Manufacturing process of PVC crust boardManufacturing process of PVC crust board
With its unique performance and beautiful appearance, pvc crust board is widely used in major industries. I believe that many customers are interested in its production process. I will introduce it in detail for you:
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. It is mainly produced by the direct motion stirring of the roller press, the rotation of the roller and the high temperature rolling. Films with a thickness of 0.3 mm to 0.7 mm are printed on the front side of the film at the same time of production and by a printing machine, and a layer of back coat is attached to the back of the film by a back coater. Don't underestimate this layer of back coating, it is an important guarantee for the high quality performance of PVC film. The back coating is composed of special materials and is a kind of high-energy affinity agent. It is precisely because of this layer of back coating that the PVC film can be tightly fused with the medium-density board or other boards. It will not be glued for ten or even fifteen years. The biggest problem with ordinary face masks is that they cannot solve the problem of film shedding. Since the entire production process is carried out at high temperature (the temperature in the roller press reaches 220 degrees), this makes the PVC film with high light resistance and fire resistance, ensuring the high quality of the PVC film. Of course, this has high requirements for production machines. Usually, the production cost of a production line is about 39 million marks, which is equivalent to about 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, so from a comprehensive perspective, PVC is actually a product with low input and high output.
