The reason why PVC can be widely used in the building materials industry is two important reasons:

One is the unique performance of PVC (rainproof, fireproof, antistatic, and easy to mold), and the second is the low input and high output of PVC. So why can PVC have the above two advantages? Let's find the answer from its production process.

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 the printing machine, 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 is composed of special materials and is a kind of high-energy affinity agent. Because of this back coating, PVC film can be tightly integrated with the middle dense plate or other plate materials. It does not open glue in ten years or even fifteen years. The biggest problem with ordinary veil is that it cannot solve the detachment of the film. 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. Of course, the requirements for production machines are very high. Usually the production cost for a production line is 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, 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.
