What is pvc material Three main characteristics of pvc material

pvc material was first discovered in France and Germany respectively, is a white solid, fragile, no practicality. Later with the commercial slowly evolved into the current decoration materials, with the continuous progress of science and technology, pvc material used in various fields, in life we see the most is used for the top layer of the ceiling. So what is pvc material? Here is a brief introduction to pvc is what material, what are the characteristics of it.

PVC is what the material

pvc is known as poly vinyl chloride ( PVC molecular structure ) abbreviation. Commonly speaking, our common pvc is a kind of plastic decorative material. Its chemical name is polyvinyl chloride. It is made of vinyl chloride monomer by polymerization reaction of amorphous thermoplastic resin plus certain additives (such as stabilizers, lubricants, fillers, etc.) composition. It has mechanical properties, strong resistance to acid and salt, and low softening point. Chemical properties are stable. Commonly used in the production of sheet, wire, cable insulation, seals and other items.

The essence of PVC is a vacuum blister film, used for all kinds of panels of the surface layer of the packaging, so it is also known as decorative film, with adhesive film, used in building materials, packaging, pharmaceuticals and many other industries. Among them, the building materials industry accounted for the largest proportion,

for 60%, followed by the packaging industry, there are a number of other small-scale application of the industry.

The three main characteristics of pvc material

1, perfect structure

pvc is a material, PVC is the world's favorite, quite popular and is also widely used in a synthetic material. Its global usage is the second highest among all kinds of synthetic materials. According to statistics, only in 1995 a year, not PVC in Europe's production volume of about five million tons, while its consumption is 5.3 million tons. In Germany, PVC production and consumption of an average of 1.4 million tons. PVC is 4% growth rate in the world-wide production and application. In recent years, the growth rate of PVC has been particularly significant in Southeast Asia, where there is an urgent need for infrastructure development. PVC is the most suitable material for the production of three-dimensional surface films.

2, strict process

First, the unique properties of PVC (rain, fire, anti-static, easy to mold). PVC production process is not complicated, the ordinary production line generally consists of rolling machine, printing machine, back coating machine and cutting machine, mainly through the rolling machine of the direct stirring, roller rotation and high temperature rolling production of a thickness of 0.3 mm to 0.7 mm of the film, production at the same time and through the printing machine and the printing of the film. The film is produced with a thickness of only 0.3 mm to 0.7 mm, and at the same time printed on the front side of the film by the printing machine, and back-coated on the back side of the film by the back-coating machine with a layer of back-coating.

Don't underestimate the back coating, it is an important guarantee of the quality performance of PVC film. Back coating by a special material, is a high-energy affinity agent, it is because of this layer of back coating, PVC film can be tight and in the dense board or other board fusion together, ten or even fifteen years do not open the glue. The biggest problem with ordinary laminating film is that it is impossible to solve the problem of film shedding. Because the whole set of production process is in the high temperature (rolling machine temperature reached 220 degrees), which makes the PVC film has a high light resistance and fire resistance, to ensure that the PVC film of high quality.

Secondly, PVC low input high output characteristics. pvc on the production of machinery requirements are very high, usually a set of production line production equipment cost about 39 million marks, equivalent to about RMB 160 million yuan. But on the other hand, the production process of PVC film is quite simple, the machine output is also very large, so comprehensively, PVC is actually a low-input, high-yield products.

3, extraordinary performance

PVC film is the application of special vacuum film press in 110 degrees of high temperature pressure attached to the surface of the sheet, not easy to fall off. pvc is what material? The raw materials used in the production of PVC film in Germany are specially refined, the toxic substances are completely refined out, so PVC is completely non-toxic and odorless, there is no *** on human skin or respiratory system, for those who are allergic to wood and paint, the use of PVC film packaging of furniture or kitchen utensils is very suitable. Through the use of PVC film as a decorative film, people can use a large number of medium density board, particle board, plywood and fiberboard, reducing the amount of wood used, thereby reducing the destruction of forests and even the environment. From this point of view, PVC film has made a great contribution to the protection of the ecological environment.
