What Is a Solar Charge Controller?

A solar charge controller manages the power going into the battery bank from the solar array.  It ensures that the deep cycle batteries are not overcharged during the day and that the power doesn’t run backwards to the solar panels overnight and drains the batteries. Some charge controllers are available with additional capabilities, like lighting and load control, but managing the power is its primary job.

 

A solar charge controller is available in two different technologies, PWM and MPPT. How they perform in a system is very different from each other. An MPPT charge controller is more expensive than a PWM charge controller, and it is often worth it to pay the extra money.

 

PWM Solar Charge Controller

A PWM solar charge controller stands for “Pulse Width Modulation”. These operate by making a connection directly from the solar array to the battery bank. During bulk charging, when there is a continuous connection from the array to the battery bank, the array output voltage is ‘pulled down’ to the battery voltage. As the battery charges, the voltage of the battery rises, so the voltage output of the solar panel rises as well, using more of the solar power as it charges. As a result, you need to make sure you match the nominal voltage of the solar array with the voltage of the battery bank. *Note that when we refer to a 12V solar panel that means a panel that is designed to work with a 12V battery. The actual voltage of a 12V solar panel, when connected to a load, is close to 18 Vmp (Volts at maximum power). This is because a higher voltage source is required to charge a battery. If the battery and solar panel both started at the same voltage, the battery would not charge.

 

A 12V solar panel can charge a 12V battery. A 24V solar panel or solar array (two 12V panels wired in series) is needed for a 24V battery bank, and 48V array is needed for 48V bank. If you try to charge a 12V battery with a 24V solar panel, you will be throwing over half of the panel’s power away. If you try to charge a 24V battery bank with a 12V solar panel, you will be throwing away 100% of the panel’s potential, and may actually drain the battery as well.

 

MPPT Solar Charge Controller

An MPPT solar charge controller stands for “Maximum Power Point Tracking”.  It will measure the Vmp voltage of the panel, and down-converts the PV voltage to the battery voltage. Because power into the charge controller equals power out of the charge controller, when the voltage is dropped to match the battery bank, the current is raised, so you are using more of the available power from the panel. You can use a higher voltage solar array than battery, like the 60 cell nominal 20V grid-tie solar panels that are more readily available. With a 20V solar panel, you can charge a 12V battery bank, or two in series can charge up to a 24V battery bank, and three in series can charge up to a 48V battery bank. This opens up a whole wide range of solar panels that now can be used for your off-grid solar system.

 

The Key Features Of A Solar Charge Controller Are:

 

  • Multistage Charging Of Battery Bank:

Changes the amount of power set to the batteries based on its charge level, for healthier batteries.

  • Reverse Current Protection:

Stop the solar panels from draining the batteries at night when there is no power coming from the solar panels.

  • Low Voltage Disconnect:

Turn off attached load when battery is low and turns it back on when the battery is charged back up.

  • Lighting Control:

Turn attached light on and off based on dusk and dawn. Many controllers are configurable, allowing settings for a few hours or all night, or somewhere in between.

  • Display:

May show voltage of battery bank, state of charge, amps coming in from solar panel.

 

If you are looking for high quality solar charge controllers, I recommend that you can visit the website of Power Master Technology Co., Ltd. which is the professional solar panel manufacturer in the industry. You can find numerous solar charge controller related products on their website. Feel free to send inquiries to Power Master to obtain the product you need.

The toilet flush valve is a key element in the toilet tank. The flush valve is not at fault very often.

 

The toilet flapper can cause the toilet to run intermittently or not flush correctly. Before you assume it is the flush valve make sure the flapper is not the culprit.

 

It includes a fill tube and the flapper and water inlet for the toilet bowl. Most replacement kits include a new gasket for the tank and bolts to hold the tank in place. You will want to replace the flush valve if the seal between the tank and the bowl is leaking and does not respond to tightening. Or if the flapper will not seat even after being replaced.

 

Replacing a Toilet Flush Valve

Draining the Tank

Draining the toilet tank is the first thing you want to do before working on a flush valve. Toilet tanks have a lot of water in them that can get everywhere. It is clean water, but still, it makes a mess.

 

Turn off the water supply to the toilet first. Most tanks have a fill line marked on the side of the tank. Some do not. You can use a marker to put a mark at the correct water level if it is missing. The new flush valve tube may be a different height than the old one.

 

With the water turned off, flush the toilet to drain out most of the water from the tank. Place a pail below the nut for the toilet tank inlet. Loosen the nut on the water supply line. If the water is off, you should not get much water from the supply line.

 

There will be about an inch of water left in the bottom of the tank. Sopping the water up with rags will be a tedious task. The best way to finish draining the tank is to loosen the nut to the toilet fill valve. Loosen the nut to the fill valve and let the water drain into the pail.

 

Any water that you do not remove is likely to wind up on the floor. Removing the toilet flush valve will completely open up the bottom of the tank. Draining the toilet tank prior to this step is important.

 

Removing the Toilet Tank Bolts

Removing toilet tank bolts begins with the right tools. The tops of the bolts usually take a large flat blade screwdriver. On the underside of the bolts you may find brass or plastic nuts. The plastic nuts may have wings on them that allow you to hold them with your fingers, this is nice feature.

 

Depending on the configuration of your toilet, you might need an adjustable wrench, box end wrench or even a deep socket wrench.

 

You may have gotten a tool with the toilet that was used to tighten these nuts. Your builder or plumber may have thrown it away. Finding it now may be a challenge. Before you begin, try to locate wrenches that you can use on the nuts in question.

 

The tank is held onto the base by two or three bolts that are visible from inside the tank. Many times you can hold the plastic nuts with your fingers. Loosed and remove both bolts. That’s all there is to it, the tank should be free. Place a piece of cardboard on the floor and pull the tank up from the base. Lay it on its back on the cardboard.

 

Removing the Flush Valve

After you have removed the tank from the base, removing a toilet flush valve is pretty easy. Lay the tank on its back to see the washer and nut for the flush valve.

 

Before you purchase a flush valve, make sure you know the size. Most of them are a nominal 3″ or 4″ diameter. If you are not certain, you want to take the old flush valve with you to match it up.

 

Certain brands of toilets have proprietary flush valves that only fit that brand of toilet. This is usually only true of more expensive toilets. If you are in doubt, check the internet for your model of toilet to see which flush valve it takes.

 

Remove the rubber washer from the base of the tank. There is a large plastic nut that holds the flush valve in place. Use a large pair of adjustable pliers to remove the nut, holding the valve assembly from the inside of the tank.

 

Remove the tubing that is connected to the top of the flush valve tube. Remove the large nut and the flush valve should be free. Remove and discard the old flush valve along with the flapper. You should have gotten a new one with the flush valve kit.

 

Installing a New Flush Valve

By this time you should have the old flush valve removed. Before installing the toilet flush valve you want to get the instructions for the new one. Follow the instructions on the new valve to properly locate the washers and nut.

 

Put the new flush valve into the tank and orient it appropriately the same way the old one was. There should be a washer between the valve and the tank, if it is supplied loose you will need to put it on. Put the plastic nut on and tighten it down.

 

Obviously, with plastic fittings you want to exercise some caution with tightening them. On the other hand, make sure the nut is snug. If you get a leak from this connection, you will have to start all over again. Yes that is correct, you won’t know until it is all put together and you turn the water on.

 

Place the main seal over the outlet and push it up to the bottom of the tank. Attach the tubing at the top of the fill valve. At this point the inside of the tank should look similar to how it was when you took it apart.

 

Replacing the Toilet Tank

You may want a little help replacing the toilet tank. It is fairly heavy with all of the parts inside. In addition, it is a little awkward to handle.

 

Put the tank back on the toilet base and start the bolts and washers through the holes. Put the wing nuts on and snug them up finger tight. Hold the wing nuts and use the screwdriver to tighten the bolts.

 

Tighten them down evenly, switching back and forth. Do not over tighten. Make sure the tank is secure.

 

Hook the flapper chain to the tank lever making sure that there is no slack. It should operate freely, up and down.

 

Make sure the nut for the fill valve is snug and then hook up the water supply. Tighten the nut for the water supply line, don’t over tighten it, and remember it is plastic. Turn the water back on and check for leaks. First check the water supply and then the main seal. No leaks, good. The float for the tank should still be set at the proper height.

 

When the tank stops filling, check the water level. Too low, adjust the float until the tank fills to the correct level. After that, flush the toilet. All your problems should be solved.

 

Summary

So replacing a toilet flush valve is a little bit of work. Taking the tank off sounds a little scary at first. Once you are past that it is a breeze. One big plastic nut and a few bolts to tighten. You have to do a leak check, but that’s not hard.

 

All done, toilets works great, Good Job! This is a home repair has a higher level of difficulty. By following the instructions and taking your time you were able to do it. What’s even better is that you saved some money, great.

 

If you are looking for high quality toilet flush valves, I recommend that you can visit the website of Kingsway Technology Inc. The company provides electronic flush valves both for toilet and urinal uses. Its products feature easy installation to convert manual flush valve to automation. Kingsway is the best choice of automatic sanitary products manufacturer for you.

The intent of this article is to cover all the important things to consider and provide information to help you choose the right spray gun for you.

 

If you are just getting started in spray application you may be over whelmed by all the variables that are to be considered. From choosing the right coating, to safety considerations when spraying, to choosing the actual spray equipment. If you have been able to wade through the choices you may be at the point that you have decided you will be using a spray gun and want to determine which spray gun will best meet your needs.

 

Variable 1 – Fluid Viscosity

 

Viscosity is usually referenced as low, medium or high but if you do not have the viscosity of your coating provided you can also use a measuring device like a Zahn cup which will give you a reading in seconds. You can then use a conversion chart to determine the viscosity of a given coating. Most spray gun manufacturers including Binks and Devilbiss will often list the proper spray gun set up based on the coating viscosity you will spray using a certain cup like for the Trophy Gun the viscosity is listed in seconds in a Zahn 2 Cup. You can also often get a spray gun recommendation on the technical data sheet for your coating. However if you will be spraying a variety of coatings then having a general reference point of the coating type and viscosity of the coating will give you the ability to reference what spray gun setup might be ideal.  In general certain types of spray guns are better suited for heavy viscosity coatings than others.

 

For high viscosity coatings like zincs, enamels, ceramics, or glues you will typically want to use a conventional spray gun. Or if you need to spray even heavier bodied coatings or need higher production then you will often want to consider an Airless or Air Assist Airless.

 

For other coatings it will depend on your finish requirements. HVLP will help reduce the coating you use by having higher transfer efficiency. LVMP will allow for similar transfer efficiency to HVLP but may not meet environmental regulations in certain industries, conventional will provide the finest atomization but can use twice as much paint in a given time that HVLP will.

 

In addition to having implications for the type of gun to choose, viscosity will also be important in determining how fluid is delivered in a spray gun. The three ways to feed paint to a spray gun include pressure, suction, or gravity. Each feed method has its benefits and limitations. In general Gravity feed spray guns will keep waste to a minimum and provide ease of use. However to use a gravity feed spray gun the material must be thin enough to flow easily. Suction feed spray guns will have similar fluid flow requirements to gravity fed spray guns. Suction fed spray guns do offer potential agitators which can be helpful for coatings that require agitation. Suction feed spray guns will require slightly more cleaning. If your coating is highly viscous you will most often need a pressure fed spray gun. Pressure feed spray guns can supply highly viscous coatings easily making them the ideal choice for high viscosity coatings.

 

Variable 2 – Production Requirements

In addition to a variety of feed methods and air cap styles, high quality spray guns have a variety of set ups available. By offering larger air caps and fluid nozzles you will be able to choose a spray gun that will be able to provide the production level you need or if a spray gun is not fast enough you may want to consider an airless.  You can get an idea of what production you can expect out of various fluid nozzles here. The Air Cap you choose will determine a few important things including the size of the spray pattern and the caps ability to break up heavy viscosity coatings the higher the CFM of the air cap typically the heavier bodied coating it will atomize. BY knowing your production requirement you can be better able to choose the right fluid nozzle and air cap

 

In addition to choosing the air cap and fluid nozzle the Production requirement will be pertinent in choosing how you feed your spray gun. Pressure pots offer higher volumes of coating which can be ideal if you will be spraying more than a gallon of paint at a time. They also provide greater control over your fluid and air pressures which can help in meeting a production goal. Or if you need the ability to continuously paint you can feed your spray gun from a diaphragm pump or fluid transfer pump. If you will be painting in small quantities and not have coatings with high viscosity then gravity or siphon feed spray gun could be ideal.

 

Variable 3 – Compressed Air Availability

Different spray equipment will need different amounts of air. A typical spray gun can require 20 CFM of air while an airless can often require significantly more if it is air fed using up to 120 CFM. You can learn more about compressor requirements for spray equipment here.

 

Variable 4 – Finish Quality Requirements

A final variable to consider is the finish requirements you will need. Spray guns are typically the best appearing finishes. If the coatings are not highly viscous most of the times you can achieve an automotive quality break up of a coating with HVLP, Conventional, or LVMP.

 

However with heavier bodied coatings you will typically need a conventional gun to get good break up. An air assist airless will provide a finish that is close to a spray gun but not quite the fine finish, they are often used for higher production that requires a quality finish. If you primary need high production or spraying high solids coatings you will typically need an airless.

 

Variable 5 – Length and Diversity of Use

Spray guns vary greatly in their prices as well as their quality. Higher quality spray guns offer greater variety of air caps, fluid nozzles, and are able to be completely rebuilt. Lower cost spray guns will often not be rebuild able and have limitations on the variety of set ups that are available. You can learn more about spray gun prices and quality differences here.

 

Conclusion

Choosing the right spray gun for your coating can be a lot to consider. By knowing more about your finish quality, production, compressed air, and viscosity of your paint you will be able to better determine the right spray equipment for you.

 

By the way, if you want to find quality spray guns, I can recommend that you can try to visit the website of the professional spray gun manufacturer – KSPARK International Ltd... The company is specializing in kinds of air spray guns, air blow gun, mini compressor, and much more… For more details about spray gun series, welcome to check out Kspark’s website: www.kspark-spraygun.com to see what products they can offer you.

A Brief Discussion of Composite Materials

On October 13, 2017, in Fabrics, Manufacturer, Textile, by Jasmie K.
0

Does “composite materials” sound familiar? And do you know what it is? This overview will show you a brief discussion of composite materials.

 

Definition

A “composite” is when two or more different materials are combined together to create a superior and unique material. This is an extremely broad definition that holds true for all composites, however, more recently the term “composite” describes reinforced plastics.

 

Background on Composites

The history of composite materials dates back to ancient times for construction applications; straw was mixed with mud to form a building material known as adobe.

 

The straw provided the structure and strength, while the mud acted as a binder, holding the straw together in place.

 

Since the days of adobe, the use of composite materials has evolved to commonly incorporate a structural fiber and a plastic, this is known as Fiber Reinforced Plastics or FRP for short. Like straw, the fiber provides the structure and strength to the composite, while a plastic polymer holds the fiber together. Common types of fibers used in FRP composites include:

 

  • Fiberglass
  • Carbon Fiber
  • Aramid Fiber
  • Boron Fiber
  • Basalt Fiber
  • Natural Fiber (Wood, Flax, Hemp, etc.)

 

In the case of fiberglass, hundreds of thousands of tiny glass fibers are compiled together and held rigidly in place by a plastic polymer resin. Common plastic resins used in composites include:

 

  • Epoxy
  • Vinyl Ester
  • Polyester
  • Polyurethane
  • Polypropylene

 

Examples of Composites

The most common example of a “composite” in a broad sense is concrete.

 

In this use, structural steel rebar provides the strength and stiffness to the concrete, while the cured cement holds the rebar stationary. Rebar alone would flex too much and cement alone would crack easily. However, when combined to form a composite, an extremely rigid material is created.

 

The composite material most commonly associated with the term “composite” is Fiber Reinforced Plastics.

 

This type of composite is used extensively throughout our daily lives. Common everyday uses of fiber reinforced plastic composites include:

 

  • Aircraft
  • Boats And Marine
  • Sporting Equipment (Golf Shafts, Tennis Rackets, Surfboards, Hockey Sticks, Etc.)
  • Automotive Components
  • Wind Turbine Blades
  • Body Armor
  • Building Materials
  • Water Pipes
  • Bridges
  • Tool Handles
  • Ladder Rails

 

Benefits of Composites

In comparison to common materials used today such as metal and wood, composites can provide a distinct advantage. The primary driver and advantage in the adoption of composite materials are the lightweight properties. In transportation, less weight equates to more fuel savings and improved acceleration. In sporting equipment, lightweight composites allow for longer drives in golf, faster swings in tennis, and straighter shots in archery. While in wind energy, the less a blade weighs the more power the turbine can produce. Besides weight savings, the most important benefits of composites include:

 

  • Non-Corrosive
  • Non-Conductive
  • Flexible, Will Not Dent
  • Low Maintenance
  • Long Life
  • Design Flexibility

 

If you have any interest in composite materials, you can try to visit the website of Taiwan Electric Insulator Co. Ltd. TEI has a vast range of specific material for your needs, from electroplated glass-fiber, the latest bulletproof aramid fabrics to high spec carbon fiber and carbon modulus.

To begin, grommets can also be known as eyelets. Many people use the terms interchangeably, referring to eyelets when they’re small-ish and grommets when they’re large-ish. In addition, if you see a sewing project that refers to eyelets, make sure to confirm if it’s the kind you install or the ones you can sew with your machine. Many upper-end sewing or sewing/embroidery machines offer an eyelet option within their selection of buttonholes.

 

In general, grommets are available in metal, rubber (for industrial purposes), and plastic (Snap-on type), and they come in a variety of colors and finishes.

 

A grommet is comprised of two pieces: a male and a female. Since we’re not too crazy about that terminology, we took to the Internet to learn how others identify the grommet parts. We discovered the male section is considered the actual grommet and the female section is a washer.

 

When these two parts are forced together, with fabric sandwiched in the middle, you end up with a fantastic looking, durable hole.

 

Grommets often serve a dual purpose in a project, a perfect blend of form and function. They add a certain industrial or modern look; in fact, sometimes metal eyelet’s only job is to look cool as an embellishment. But, they usually have very defined purposes as channels, handle anchors, and more. You see grommets on garments, accessories, and certainly in plenty of home décor items.

 

Grommets and Installation Tools

Grommets and the tools you need to insert them are readily available at your local craft or fabric supplier (in store and online) as well as from many hardware suppliers. Depending on where you choose to purchase your grommets, there may be a few visual differences in the tools, but probably not as much variation in the grommets themselves.

 

Grommet Kits

The first time you purchase grommets, you should buy a kit. Why? Because in a kit, you also get the tools needed for successful installation. It’s important to note that for each size grommet you buy, you need coordinating tools.

 

Afterwards, you can simply buy the grommets only and re-use the original tool. Remember, when you change to a new size, buy a new kit.

 

Actual Grommets

As we mentioned earlier, grommets are available in a range of sizes. They also come in a variety of finishes and colors.

 

Grommet Tools

The actual grommet installation “tools” can consist of a single grommet plier, or a combination of a setter and anvil. Grommet Pliers are normally used for small grommets and eyelets. For larger grommets, as we mentioned above, you use a setter and anvil to exactly match the size of the grommet.

 

If you choose to purchase your grommet kit at a hardware store, or other professional tool supplier, the tool set may contain what’s called a grommet inserting die (looks a lot like the setter and anvil) and a hole cutter. Some may also include a cutting pad. Here’s one example of a higher end kit.

 

Other Tools You’ll Need

 

  • Interfacing

Depending on the type of fabric you’re using in your project, you may need a strong layer of interfacing between or behind the fabric layers. It’s often recommended to use canvas instead of standard interfacing. If you do choose an interfacing, it should be a mid to heavy weight.

 

  • Pen, Pencil or Marker

You need to accurately mark the position and spacing of each grommet. You can use a fabric marking pen that will disappear, or even a regular pencil or marker since you will be cutting out the center and covering the outer area with the actual grommet.

 

  • Small Sharp Scissors or Xacto Knife

Once you mark the position of the grommets, you need to cut a precisely-sized hole (more on this in the steps below). Depending on the size of the grommet, that hole might be very tiny. Very sharp scissors or a Xacto knife is key to precise cutting.

 

  • Rubber (Or Rawhide) Mallet or A Traditional Hammer

You can use either in the installation. We prefer a mallet because it more evenly distributes the force of the hammering.

 

  • Sturdy Surface

Since you do have to actually hammer the grommets to secure them in place, you need a strong, sturdy work surface. Your glass coffee table would not be a good choice. A sturdy table or counter, or even the floor would be better.

 

If you need more information about metal eyelet and grommet, welcome to check out the website of Dyi Er Kang Enterprise Co., Ltd.. They are the company of specializing in producing a variety of plastic and metal garment accessories. Feel free to send inquiries to them for further details you need.

The solutions you use for your cleaning projects are essential for achieving high performance. If you want to ensure your customers are satisfied, then you need the best products and carpet cleaning equipment you can get your hands on. If you talk to different carpet cleaning professionals, you may find that they each have their own set of techniques.

 

Some floor cleaning experts prefer to skip the preconditioning step when doing carpets. Then there are others who apply pre-conditioners, but fail to do so at the recommended amounts of the manufacturer. In most cases, this is due to impatience – their sprayers are too slow, so they rush through the process with fewer products being applied.

 

Different types of sprayers are also used by experts to apply various solutions, such as deodorizers and fabric protectors. Knowing the best sprayers to use for carpet cleaning isn’t always clear-cut. Is it really required for you to use sprayers in the first place? You can clean carpets just using equipment, such as tile cleaning and truck mounted carpet cleaning machines. However, sprayers can help ensure certain products are applied correctly.

 

It all comes down to choosing the right sprayers for the cleaning process.

 

Trigger Sprayers

 

This is an economical option for carpet cleaning professionals. It’s best to use trigger sprayers when you are applying small amounts of solutions, such as a localized deodorizer, to a spot on the carpet or a couch cushion. Some experts choose to use trigger sprayers exclusively for cleaning furniture. Using this for a wide area wouldn’t be feasible.

 

Pump-Up Sprayers

 

These are the most commonly used sprayers. They can be purchased in various sizes, the smallest being quart-sized. You can use them much like you would a trigger sprayer, however, it has a higher capacity for pressure and minimizes fatigue. This is a good choice if you’re looking to apply chemicals to both carpets and furniture. You can use it for deodorizing, post treatments, pre-conditioning and other types of applications.

 

Battery / Electric Sprayers

 

Obviously, you want to find carpet cleaning equipment that will make your job faster and easier. This is what makes battery and electric sprayers attractive. It’s simple to operate and it’s portable, much like the pump-up sprayer (minus adding pressure to the tank).

 

Selecting the best sprayer all comes down to your own preferences. Living Fountain Plastic Ind. Co., Ltd. is the professional trigger sprayer manufacturer in Taiwan. They offer kinds of sprayer, pumps, and plastic bottles to clients. If you need more information about their products, welcome to check out Living Fountain’s website to find the details you need.

The Ultimate Guide to Plastic Recycling

On September 29, 2017, in Machine, Manufacturer, by Jasmie K.
0

Plastic is among the most popular and important materials used in the modern world. However, its popularity is part of the huge problem and reason why plastics should be recycled. Instead of throwing them away polluting the land and our water bodies, we can optimize the lifespan of plastics by recycling and reusing them.

 

Plastic recycling refers to the process of recovering waste or scrap plastic and reprocessing it into useful product. Due to the fact that plastic is non-biodegradable, it is essential that it is recycled as part of the global efforts to reducing plastic and other solid waste in the environment.

 

Process of Plastic Recycling

 

The following is a step by step process of plastic recycling:

 

  • Collection

 

Plastics are available in a number of forms for example plastic containers, jars, bottles, plastic bags, packaging plastic, big industrial plastics just to mention but a few. Due to their nature and availability, there are plastic collection centers and some business people have ventured into plastic collecting business as a source of income. Tons and tons of scrap plastic are collected and sent to a collecting yard where they are then packed and transported to plastic processing plants. Unfortunately, not all countries have the capacity to recycle plastic. Very few developing countries can actually recycle plastic. This means that, plastic waste is still a major problem to some countries in the world.

 

  • Sorting

 

The actual plastic recycling process starts with sorting of the different plastic items by their resin content and color. This process is also done to ensure all contaminates are eliminated. There are specially designed machines that help in sorting of the plastics according to their resin content. Then the recycling mill sorts the scrap plastic by symbols at the bottom of the plastics.

 

  • Shredding

 

After sorting the plastics, the next step is to cut the plastics into tiny chunks or pieces. The plastic bottles and containers are then ground and cut into tiny pieces or flakes. The heavier and lighter plastic flakes are separated using a specially designed machine. The separation process helps in ensuring that the different plastics are not put together or mixed up in the final product. Remember that different plastics are used to make different items.

 

  • Cleaning

 

After a complete separation, the flakes or chunks are then washed with detergents to remove the remaining contamination. Once the cleaning process is complete, the clean flakes are passed through specialized equipment that further separates the plastic resin types. The plastic flakes are then subjected to moderate heat to dry.

 

  • Melting

 

The dry flakes are melted down. They can be melted down and molded into a new shape or they are melted down and processed into granules. The melting process is done under regulated temperatures. There is specialized equipment designed to melt down plastic without destroying them.

 

  • Making of pellets

 

After the melting process, the plastic pieces are then compressed into tiny pellets known as nurdles. In this state, the plastic pellets are ready for reuse or be redesigned into new plastic products. It is important to point out that recycled plastic is hardly used to make identical plastic item or its previous form. It is in this pellet form that plastics are transported to plastic manufacturing companies to be redesigned and be used in making other useful plastic products.

 

Advantages of Recycling Plastics

 

Plastics should be recycled because of a number of reasons as can be seen below:

 

  • Provision of a Sustainable Source of Raw Materials
  • Reduces Environmental Problems
  • Reduces Landfill Problems
  • Consumes Less Energy

Electroplated diamond cutters are used for cutting marble, tile, FRP, carbon or graphics.

Electroplated Diamond Cutters

Electroplated Diamond Cutters have very sharp cutting performance and generate minimum heat. Unlike metal bond diamond cutting tools (Sintered, Laser Welded & Silver Brazed Blades), Electroplated Diamond Cutters are more suitable to be used on dry cutting. For they have very high concentrated diamonds rigidly bonded on the surface by nickel alloy and the diamond particles protrude from the bond. The nickel bond electroplated diamond cutting discs are particularly suitable for beginning cutting operation.

 

One of the unique advantages of the Electroplated diamond cutting discs is flexibility of making into almost any diamond coating designs and specifications.

 

  • Continuous rim cutting discs provide smoother cutting on fiberglass, plastic, ceramic tiles & etc.
  • Segmented rim cutting discs are more suitable for cutting marble, granite and abrasive materials where chipping is not a problem.

Buying Tips of City and Hybrid Bikes

On September 27, 2017, in Bike Tools, Health, Manufacturer, Sport, by Jasmie K.

Looking for an easy and affordable way to enjoy get outside for fitness – and fresh air? Wishing you could find a stress-free and more manageable approach to running errands? Want a new outlet for commuting, or recreation that is less aggressive than a traditional road bike but still lightweight and sporty and fun to ride?

 

These are the reasons many people choose a City or Hybrid bicycle. But this isn’t your mom or dad’s old bike. Older “vintage” bikes are often made of steel, fewer gears, and slower and heavier to ride. Advances in the engineering of bicycles and city bike frames make these bikes faster, more responsive, and generally more fun to ride than what you might have experienced 10 or 15 years ago.

 

Here are a few easy questions/considerations to help you select the best bike:

 

  • Where do you plan on riding?
  • Is top quality a priority, or is affordability more important?
  • Do you plan to lock your bike up on the street?
  • Do you consistently select high-tech gadgets or do you prefer practical, simpler designs?
  • What is your budget for this purchase? (This is an easy way to narrow down the selections.)
  • What type of riding do you plan to do?

 

The last question is one of the best ways to determine which bike type is the correct choice. If you envision leisurely Sunday rides up the West Side Highway, occasional outings with friends in search of the perfect picnic spot and having fun while you exercise, commuting to or from work in a low-key experience, or running errands with a bike that is lightweight and easy to maintain, a hybrid or city bike is a great choice.

 

There is some variation within the models, to accommodate your preferences. Cruiser or comfort bikes will be slower, but have a vintage appeal and their step-through features, suspension systems, and cushier saddles are friendlier for people less flexible or comfortable with their feet too far from the ground.

 

If you’re looking to commute, city and commuter bikes offer features such as racks, fenders, lights, bells and kickstands – all you need to be equipped for the streets, and tow your belongings.

 

If you plan to ride longer distances, climb hills and work a bit to get in better shape, you still want to be comfortable, but you’re interested in lightness, nimble handling and even easy climbing, hybrid bikes are a perfect fit. A versatile jack-of-all-trades, hybrids are lighter and roll and pedal more easily than comfort bike. Some hybrids are designed for occasional off-road (trail) use, too.
