Advice 1: How to melt plastic

In the manufacture of a variety of plastic structures sometimes it is necessary to melt the material to give it desired shape or to connect the parts together. Carrying out melting of plastic products and plastic, be careful, as a poorly timed heat exposure may cause a fire.
How to melt plastic
You will need
  • - capacity for melting plastic;
  • - soldering iron or soldering station;
  • - gas burner;
  • - industrial dryer;
  • - welding gun.
Instruction
1
Before you start melting the plastic, try it out with a small piece. Not every type of plastic is susceptible to melting under normal conditions, so it is advisable to find out during the experience. A piece of material to grab with forceps or tweezers and hold it close to the open flame of a candle or gas burner. Heated plastic will either melt slowly or immediately begin to burn in the open air.
2
Making sure that plastic can be melted, chop the source material and place it in a metal container, for example, in a tin can. For the safety of the melting material, a container of shredded plastic insert in another bowl with large size. Fill it with water and put the whole construction on fire or stove, making a kind of water bath. This method is suitable for processing plastic with a low melting point.
3
To melt small pieces of plastic, use the heated tip of a soldering iron or a gas torch. If possible, use a soldering station with a built-in adjustment of heating temperature of the tip. Need to pick up the melting temperature on the basis of the experiment. Too high temperature may cause ignition of the material or make the plastic brittle.
4
For melting plastic with high strength use the welding gun or heat gun. The working procedure of welding gun is indicated in the technical documentation. Set includes filler materials for welding different types of plastic and plastic, for example, to fuse the seams of the connected products.
5
When processing plastic of high temperatures observe precaution. Preferably all procedures are done in the open air to avoid poisoning with burning products. Avoid contact of the melt on the exposed parts of the body and clothing to prevent burns and damage tissue.

Advice 2: Liquid plastic applications

Not so long ago on the market of construction materials are a liquid plastic. This polymeric material is deservedly gaining rapid popularity, providing us with amazing opportunities. To understand what can be useful for liquid plastic, consider the quality and scope of this material.
Liquid plastic applications

Mounting and sealing of



Liquid plastic is available in the form of glue. Operates on the principle of diffusion welding, when the molecules are stuck together as if objects penetrate each other and the surface become one.

In the case when we need to join materials made of foamed or solid PVC so the glue is indispensable. Inherent excellent weather resistance (temperature, humidity, etc.) and resistance to UV radiation, which is very important, for example, when working with plastic glazing. Another unique feature - when applied topically, the adhesive does not yellow. This allows you to use it as a great sealant.

Impact resistant decorative coating



There is also enamel "liquid plastic" aka "liquid plastic". This extra-strong paint with a high gloss. Due to the high abrasion resistance, it can be used in places with high traffic and loads. This could be warehouses, stores, garages. You can also handle floors and stairs in residential buildings. Irreplaceable liquid plastic in the treatment of swimming pools. This coating is resistant to water, oils and petroleum products. High workability – easy to apply and has a high hiding power. The basis for applying can be bricks, concrete, wood, plaster, previously painted with alkyd and acrylic paints surface steel, galvanized surface.

Stop rust



If you want to defeat the corrosion liquid plastic with inhibitor rust is a very good technological solution. First, the high adhesion of this material to the metal ensures that the coating will remain intact for a long time. The second advantage is that you can apply paint directly on rust, without spending time on the surface of the soil and waiting for it dry. Dense texture and high content of anti-corrosion additives will eliminate the re-appearance of rust, and the lifetime of the coating is 7-10 years. As a rule, enamel "liquid plastic" used to protect pipelines and other engineering structures made of metal.

Despite the uniqueness of this modern building and finishing material it should be noted that the liquid plastic can not be classified as organic products. The material in all of its modifications has a strong odor and requires the use of personal protective equipment – respirator and gloves. A wide range of applications and a large number of constituents makes a closer approach to the selection of material for the realization of the idea. Use liquid plastic is only for the purposes and according to instructions.

Advice 3: What is different plastic from plastic

In society there is a perception that plastic and plastic is a different material that differ from each other quality. Supposedly the plastic is stronger and better. Plastic, according to the allegations, the lower quality and fragile. This is a myth and nothing more.
Plastic is the main material for the production of goods for everyday use.

What kind of material is plastic



Plastic, it is plastic, is organic material, which are synthetic or natural high-molecular compounds, so-called polymers. Especially wide application in the production of got plastic on the basis of synthetic polymers.

The name of this material implies that under the influence of heat and pressure it can take a given shape and store it after cooling or curing. In fact, the process of manufacture of plastics represents the transition of the material from viscous to solid state.

The history of plastic



The history of plastic begins in 1855. It was received by English Metallurgist and inventor, Alexander Parkes named parkesine. A little later she had another name - the celluloid.

The development of plastics as materials started with the use of natural components, possessing good ductility, chewing gum and shellac. A little later began to be used chemically modified natural materials - rubber, nitrocellulose, collagen and galalith. As a result, their production has come to the use of fully synthetic molecules, bakelite, epoxy, polyvinyl chloride and polyethylene.

For a long time parkesine was the brand name of the first artificial plastic was made from cellulose treated with nitric acid and solvent. In the second half of the 19th century it was often called faux ivory.

In 1866, the year Alexander Parkes created my own firm, involved in the mass production of parkesine. But after two years she broke, as Parkes tried to reduce costs of production, and it's detrimental impact on the quality of the final products.

Successors parkesine steel xylonite, which was produced by Daniel Spillum, a former employee of the parks and celluloid, produced by John Wesley Hyatt.

The origins of misconceptions



Plastic and plastic — the same material. And the difference between them comes down only to the point of view of the Russian language. "Plastic" is the short name for plastic, but due to the nature of the advertising of the filing of this words it has become associated in the consumer with high quality and reliability. Moreover, thanks to the competent advertising formed the opinion that plastic products are manufactured exclusively in Japan. Plastic was considered a product of poor quality, fragile, brittle and even harmful, if it was made in China or third world countries.

The way of presenting information about plastic affects only the perception of the consumer – positive or negative - but not on the quality of this material.
