1, the structure of the United States
What PVC material is PVC? PVC is a kind of synthetic material that is popular, popular, and widely used in the world today. Its global use ranks second among various synthetic materials. According to statistics, in 1995 alone, PVC production in Europe was about 5 million tons, while its consumption was 5,300,000 tons. In Germany, PVC production and consumption average 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%. In recent years, the growth of PVC in Southeast Asia has been particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC is a composite material.
2, strict process
(1), PVC unique performance (rain, fire-resistant, anti-static, easy to shape). The production process of PVC is not complicated. The common production line is generally composed of a roller press, a printing machine, a back coater and a cutting machine, and is mainly produced through the direct-acting stirring of a roller press, the rotation of a roller, and the high temperature rolling to produce a thickness of only For a film of 0.3 mm to 0.7 mm, the color is printed on the front surface of the film at the same time and by a printer, and a back coat is attached to the back of the film by a back coater. Do not underestimate this layer of back coating, it is an important guarantee for the quality of PVC film. The back coating consists of special materials and is a kind of high-energy affinity agent. Because of this back coating, the PVC film can be tightly integrated with the middle dense plate or other plate materials. It does not open glue for ten years or even fifteen years. However, the problem with ordinary masks is that they cannot solve the problem of film shedding. Because the entire production process is carried out at high temperatures (220 degrees inside the roller press), this gives the PVC film high light resistance and fire resistance, ensuring the high quality of the PVC film.
(2), PVC low input high output characteristics. Pvc has a high demand for production machines. Usually, the production cost of a production line for a production line is about 39 million marks, equivalent to about RMB 160 million yuan. On the other hand, the production process of PVC film is quite simple, and the output of the machine is also very large. Therefore, in a comprehensive view, PVC is actually a product with low input and high output.
3, extraordinary performance
The PVC film is applied on the surface of the sheet at a high temperature of 110 degrees using a dedicated vacuum laminator and is not easily peeled off. What is pvc? Germany's raw material for the production of PVC film is specially refined, and toxic substances are completely extracted. Therefore, PVC is completely non-toxic and odorless, without any irritation to the human skin or respiratory system. For those who want to use wood and paint For allergic people, PVC film-packed furniture or kitchen utensils are very suitable. By using a PVC film as a decorative film, people can use a large number of medium-density panels, particleboards, plywood, and fiber boards to reduce the amount of wood used, thereby reducing damage to the forest and the environment. From this perspective, PVC film has made a great contribution to the protection of the ecological environment.
