Fireproof pvc foam board 12mm strict process

PVC is widely used in the building materials industry, not only because of the unique properties of PVC, but also because of the stringent production process of PVC. PVC crust board manufacturers today to tell you about this issue, we all know that PVC crust board is the main component of PVC, PVC production process and the use of PVC clad board performance has a great relationship, then, the following Let us learn together.

In fact, the production process of PVC is not complicated. The ordinary 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. Films of only 0.3 mm to 0.7 mm are produced at the same time and printed on the front of the film by a 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.
