If you decide to use polyvinyl chloride in construction or repair, what is it important to know before starting work. This material belongs to synthetic thermoplastic textures.
PVC specifications
In the conditions of the plant, two types of PVC are produced, the first of which is plasticized, while the second is unplasticized. In the latter case, no plasticizer is used. Externally, PVC has the form of a white powder, which has no smell. It has high strength qualities and dielectric properties. If you decide to purchase polyvinyl chloride, what it is, you need to find out. It is resistant to alkalis, mineral oils, acids and does not dissolve in water. Dissolution and swelling are facilitated by ketones, ethers, as well as aromatic and chlorinated hydrocarbons. The material is resistant to oxidation and almost does not burn. Polyvinyl chloride has not very impressive heat-resistant characteristics; when exposed to a temperature of 100 degrees, it begins to decompose. In order to achieve heat resistance and improve solubility qualities, PVC is subjected tothe effects of chlorination.
Use area
Today, polyvinyl chloride is widely used. What is it that every home master and specialist in the field of construction should know. This material is used in medicine, replacing glass and rubber. Thus, it was possible to obtain disposable items. Due to its chemical stability and inertness, PVC has gained high popularity in the mentioned field. Products from it are diverse and easy to manufacture, and are much cheaper than previously used materials.
PVC is also used in the transportation industry. It is used in the production of door panels, armrests, as well as in the creation of cable insulation. It is thanks to this that the car began to have a longer life span, which increased by six years compared to previous indicators. This approach has increased the safety of transport, since with the help of PVC it was possible to create airbags, as well as protective panels that can protect passengers from injury in accidents.
Repair and construction
Considering polyvinyl chloride, what it is can be found in this article. This material is used today for design purposes. This opportunity arose due to the fact that modern technology allows you to create PVC products of any shape. Thus, it was possible to create interior elements. Most often, this polymer can be found in construction. From it are obtainedwear-resistant, rigid, lightweight products that are excellent at resisting corrosion and chemical attack. Such a high popularity in the field of construction is also due to fire safety, the material is difficult to ignite, and when the source of temperature is removed, it stops burning and smoldering. That is why such products can be used at facilities that require increased fire safety requirements. PVC material is durable, more than 75 percent of the pipes made from it demonstrate life activity for more than 40 years.
Production technology
Obtaining polyvinyl chloride is carried out by the method of radical polymerization of raw materials, which is vinyl chloride. The most widely used in the industry is the suspension method, this is due to the fact that it provides high performance. Such polymerization is carried out according to the periodic system. Vinyl chloride, which is contained in an amount of 0.02 - 0.05 percent in the aquatic environment, is used as the main component. The prepared raw material is heated to 65 degrees, and then subjected to a similar effect to obtain a homogeneous product. Polymerization occurs in drops of vinyl chloride. Ultimately, it is possible to obtain porous microgranules. The production is fully automated, while the polymerization is carried out in reactors with a volume exceeding 200 cubic meters. After completion of polymerization, the degree of vinyl chloride, which by this timereacted, reaches 90 percent. The elements that were not used are removed, while the PVC itself is sifted and dried under the influence of hot air. After that, packaging takes place. Polyvinyl chloride, the properties of which were described above, is converted into vinyl plastic or plastic compound at the last stage.
PVC end products
PVC material can be converted into vinyl plastic. It is a tough product. It is characterized by high mechanical strength, chemical resistance and water resistance. Among the disadvantages are low impact strength, poor frost resistance and an insignificant operating threshold. As for plasticizers, these are soft products that have significant elasticity. They are also waterproof and oil resistant. They are resistant to all kinds of organic solvents.
Conclusion
Polyvinyl chloride, pipes from which are produced today, acts as one of the most common materials among plastics. World production accounts for approximately 17 percent of the total output of plastics, and ranks third among polymers. Products made of PVC have found their practical application in many sectors of the economy, industry, heavy engineering, medicine and agriculture. Today, plastic windows are installed in almost every house, and products based on the described material are also used. It is the wide distribution that indicates excellentthe qualitative characteristics of the material described above, which has high strength, resistance to external damage and influences of a different nature.
