Based on polyethylterephthalate (PET), Ertalyte is an un-reinforced semi crystalline thermoplastic polyester. It is manufactured from proprietary resin grades, and is found to have remarkable dimensional stability, outstanding wear resistance, high performance, a low coefficient of friction, and is able to resist acids better than polyacetal and nylon.

The following are some of Ertalyte’s impressive aspects:

• Ideal for both dry and wet environments
• Exceptional resistance to dirt
• Superb stain resistance
• Good electrical insulating properties
• Acceptable for food contact (FDA approved)
• Great creep resistance
• Good resistance to gamma and x-rays, and other high energy radiation

Ertalyte properties make it especially appropriate for the manufacture of mechanical precision parts that are meant to uphold high loads and/or are to endure wear. Compared to nylon and acetal, this material keeps more of its original strength in temperatures as high as 190° F. Furthermore, it provides better abrasion and chemical opposition, and its reduced humidity absorption allows electrical and mechanical properties to carry on almost entirely unaffected by moisture.

There is also Ertalyte TX, which is a polyethylene terephthalate compound that incorporates a solid lubricant that has been uniformly dispersed throughout it. In other words, this particular formula is PET + solid lubricant. This product not only boasts incredible wear resistance, but provides an even lower coefficient of friction, and has higher pressure-velocity capabilities compared to standard Ertalyte.

Semitron ESd (electrostatic discharge – also known as static electricity) is a family of static dissipative products that were designed to be used when there are problems with electrical discharge in operation. These products are often utilized for sensitive electronic components, examples of which include hard disk drives, circuit boards, and integrated circuits. It can help protect against static electricity damage that can damage these electrical devices.

Semitron products are an ideal option for components in high speed electronic printing and reproducing equipment, as well as in handling applications like IC device testing fixtures, inserts, wafer combs, and handling trays. Compared to many other types of “dissipative” plastic shapes, these materials are electrically stable and are inherently dissipative. They don’t depend on atmospheric phenomena to be set in motion. Furthermore, surface treatments are not needed for dissipation to be achieved. Instead, static electricity is dissipated via this family of products as readily as it is dissipated along the surface.

Each Semitron product dissipates 5 KV in less than two seconds per Mil-B-81705C. Furthermore, they are always static dissipative, they do not use graphite powder or metal, and the have continual thermal performance from 90° C to 260° C, depending on the base polymer.

Vespel SP-1 is one of many Vespel products. These materials are highly durable polyimides that are designed to provide outstanding wear resistance, low coefficient of friction, and insulation. There are many different shapes and parts, each with different attributes to accommodate the design needs of engineers.

While it can be utilized for a variety of applications, Vespel SP-1 has superior wear properties, as well as top thermal and electrical insulation for valve seats, balls, gaskets, insulators, poppets, clamping rings, and more. In fact, it is often used as a thermal conductivity reference material for the purpose of testing thermal insulators. This is because it can withstand being subjected to repeated high temperatures without its mechanical or thermal properties altering.

For many years, Vespel was the only option for those seeking high-end polymide parts, which has made it quite the exotic and expensive polymers. Now, however, those who require these special plastics for engineering applications will discover that another excellent option is Torlon. This is more cost effective materials that feature stiffness that lasts across a broad temperature range (500° F), maintains dimensional stability even when temperatures are elevated, and has bearing and wear properties that last longer compared to most exotic materials, including Vespel Sp-1. Thus, it is possible to obtain good value at a favorable price, without sacrificing performance, quality, or reliability.

What is Solar Panel (photovoltaic panel)?

Today, world is facing immense big problem regarding Energy Crisis. All we know about Current Energy sources not gonna last long and so need for alternate energy source and all that blah .. blah .. blah…!

Solar Energy could be one of major solutions to our Energy problem but how to capture that energy is main problem and that is the thing which is holding us back from using most precious Energy Source Ever, Sun!!!

So, People today have found out some ways of using solar energy for various tasks like water heating, cooling their homes etc. But we all know that most clean and useful form of energy is Electricity. With Electricity available, we can perform all the works like Heating water, Cooling houses and offices, Running Pumps, Running Industries and everything. So, researchers are making their efforts in finding something that can convert Solar Energy to Electricity. Today, we have a solution on the problem. The device is Photovoltaic Panel or PV Panel or Solar Panel.

In short, Solar Panel is the Device that converts Solar Energy and Converts it to D.C. (Direct Current) electricity.

Some Important Features of PV Panels:

1. Most Important, They make no pollution while conversion of energy, so can be called as clean energy source.
2. Solar Panels works on Sun which is forever source of energy.
3. They are Easy to Install and Simple in operation.
4. They have really low maintenance cost.
5. Solar Panel can work for long time.
6. They make no sound while working.

Construction and Working of Solar Panels:

Solar Panels is Modular structure. When we say Solar Panel, we imagine huge long shiny boards, true! So, that is called as array. This array is formed from number of Panels.

Each Panel is not elemental. It consist of much smaller Modules. And each module is then made up of number of solar cells.

So, most basic and most important part of Panel is pretty small cell. This cell is a lot like P-N junction diode in which electrons crosses the junction then travels thrugh the holes. Here, electrons take solar energy to cross the junction and so we get voltage as output. This cell is made up of silicon or germanium which are semiconductor materials.

In general, at equatorial region (where Solar Energy is maximum) the solar Pannel of size 1/5 meter can produce about 2 Ampere of Current at 2 Volt potential difference.

The performance of Solar Panels is decreased by one major factor, Heating of Panels. As the temperature of Panels grows the efficiency of Panels is decreased dramatically.

Most Important Use of Solar Panels Today:

So, can you guess where these Panels are used and function is extremely important? I bet, Satellites! Satellites need huge amounts of electricity for its various functionalities and they depend on solar panel for the same.

Limitations:

• Very high installation and Production cost.
• Solar panels need large area for energy collection so as compared to fossil fuels they are space consuming.
• Solar energy is not same in all the parts of the world.
• It is not continuous, for ex. it does not works at night so storing mechanism is necessary for working in offtime.

Hi, I am Pradeep Sharma. I have completed my Mechanical Engineering from University of Pune, Maharashtra(India). Currently, I am working with Mahindra & Mahindra Company at Nasik.

Introduction:

Pneumatic tires are manufactured according to relatively standardized processes and machinery. Annually, over 1 billion tires are manufactured in around 450 tires factories in the world. Tire factories start with bulk raw materials such as rubber ,carbon black and chemicals and produce numerous specialized components that are assembled and curred.

Construction of Tire:

The tire is an assembly of numerous components that are built up on a drum and then cured in a press under heat and pressure. Heat facilitates a polymerization reaction that cross-link rubber monomers to create long elastic molecules, which permits the tyre to be compressed in the area were tyre  contact the road surface and spring back to its original shape under high frequency cycles.

Components used in tire assembly:

1. Inner Liner:

The inner liner is an extruded rubber sheet compounded with that result in low air permeability. The inner liner assures that the tire will hold high pressure air inside, without diffusing air gradually through the rubber structure.

2. Body ply:

The body ply is a calendered sheet consisting of one layer of rubber, one layer of reinforcing fabric and second layer of rubber, earliest textile used was cotton and later materials include rayon, nylon, polyster.Passenger tires typically have one or two body plies, it give strength to tire structure .Truck tires, off-road tires, and aircraft tires have progressively more plies.

3.    side wall:

Sidewalls are non-reinforced extruded profiles with additives to give the sides of the tire  good abrasion and environmental resistance. Additives used include antioxidants and antiozonants.Sidewall extrusions are nonsymmetrical provide a thick rubber area.

4. Bead:

Beads are bands of high tensile-strength steel wire encased in a rubber compound. It is coated with special alloys of bronze or brass. Coating protect the steel from corrosion. Beads inflexible and inelastic ,and provide the mechanical  strength to fit the tire to the wheel. Bead rubber includes additives to maximize strength and toughness.

5. Apex:

The apex is a triangular extruded profile that mates against the bead.

6. Belt package:

Belt are calendered sheet consisting of a layer of rubber , a layer of closely- spaced steel cords, and a second layer of rubber. The steel cords are oriented radially in radial tire construction, and at opposing angles in bias tire construction. Belts give the tire strength. Passenger tires are usually made with two or three belts.

7. Tread:

Tread is a thick extruded profile that surrounds the tire carcass. Tread compound include additives to impart wear resistance and traction in addition to environmental resistance.

8. Side wall carcass:

This part of the tire serves as the load bearing framwork that forms the tire’s body shape.The carcass are made of rubber coated fabric as well as steel cords that are placed in radial direction.It contains the inflation pressure that helps out to support the load and the overall absorbing of impact.

9. Inner liner:

The inner liner is the area of tire that is made of special rubber that attaches to the carcass.It is designed to withstand a high resistance to air migration.

Materials used in Tire Manufacturing:

• Natural rubber is the basic elastomer used in tire making.
• Styrene-butadiene co-polymer is a synthetic rubber which is often substituted in part for natural rubber based on the comparative raw materials cost.
• Polybutadiene is used in combination with other rubbers because of its low heat-buildup properties.
• Halo-butyl rubber is used for the tubeless inner liner compound, because of its low air permeability. The halogen atoms provide a bond with the carcass compounds.
• Carbon black, forms a high percentage  of  the rubber compound. This gives reinforcement and abrasion resistance.
• Silica, with carbon black is used in high performance tires, as a low heat build up reinforcement.
• Antioxidant and antiozonants prevent  sidewall cracking due to the action of sunlight and ozone.
• Textile fabric reinforces the carcass of the tire.

Introduction:

Torlon is kind of plastic. Saying just a kind of plastic is like discrediting a lot of Torlon qualities. It is very high performance plastic. It is related to family Polyetheretherketone (Big name, mhmm!).

Major Properties of Torlon:

1. As I have initially told, its plastic. And hence its got to have very good chemical stability.

2. Apart from that, designers generally have to think about temperature considerations when they include plastic parts in their design. Because, at higher temperature most of the plastic gets dilated and fails to perform. But Polyetheretherketone torlon remains stiff and hard even at elevated temperatures.

3. Again, as it is plastic, there are lot of possibilities in manufacturing things with it as plastic allows to use molding, extruding etc. with ease.

Practical Uses of Torlon:

Torlon have very wide applications in various industries like Electronics and Telecommunications, Semiconductors, Aerospace, chemical processing and pharmacy etc.

1. In mechanical manufacturing industries, at flexible joints like bearings and bushings, needs plastic parts. But due to high speed and friction these parts get heated and don’t perform at extreme condition. Torlon have creep resistance up to 500 degree F. (260 degree C.). This employs Torlon for such jobs.

2. In aerospace industry, weight is major issue. Torlon can replace many metal parts with no compromise in work quality like wear resistance.

3. As told before, its stable. It can sustain intense chemical environments in industries. Also it stands good with fuels.

4. Connectors and fixtures can be machined from Torlon PAI to offer consistent electrical performance.

5. Torlon maintains high stiffness and strength in extreme temperature.

6. Excellent chemical resistance allows torlon to be used widely in chemical factories, laboratories etc.

7. Larger tolerance means, more scope to error. High stiffness and high temperature stability allows designer to come up with very low tolerances.

And Many More!!!

1. There are More Cost-Effect Options Than Vespel SP-1

Hello Folks!!!

As expected, consumermate.com is ready with their new category (categories! I guess!!). Firstly, I had seen consumermate in November 2009. Those times, it provided pretty nice tools and information about laptops and mobile phone handset. Soon later, they added LCD’s and Plasma TV. And now, they are ready with two more rocking products, Digital Cameras and Camcorders. At start of this article I have written “As Expected”! The reason is here. I frequently visit consumermate for latest tech products. I am monitoring that, these people have their unique concept, they have developed appropriate tools (like search and compare tools) and most important “They are constantly maintaining, updating and growing with pace!”

Searching your camera is very easy here. It’s similar to those tools Laptop search or mobile search. You can select cameras on cost and hardware basis, compare them and get complete information about products. Consumermate have new feature which lets you enter your product and contact information. Then dealers in your city will contact you.

Being related to Animation and Filmmaking field, I have used some high end cameras. Few days back, my friend purchased pretty expensive version of nikon camera. I asked him about high costs. But when I handled camera, saw its functionality and rocking outputs, I was damn amazed. It worths! I am currently using that SONY Cyber Shot and canon powershot digital camera. Canon powershot is cheaper but its performance overtakes other. Moreover, it have very simple interface so anyone can learn to use it very easily. The camera is so magnetic that sometimes I feel I am not using camera for taking photographs, but taking photographs for using the camera!

So, what yours choice Nikon or some canon slr type. Whatever! Go to consumermate.com. They know what you need to know! And by the way, after you get camera, I would like to see some photographs by you. So, don’t forget to post links to your photos below!

Till then, Have a nice time!!!
