WHAT ARE THE PROBLEMS AND CAUSES OF PVC FILM PRODUCTION

PVC membrane structure material is a membrane structure material used by general membrane structure companies. PVC membrane structure material is made of membrane structure polyester fiber and PVC membrane structure material coating. Its characteristics include: the surface treatment of PVC membrane structure material coating material is coated with acrylic resin of several microns thick membrane structure material to improve the antifouling performance of PVC membrane structure material and increase the service life of PVC membrane structure material Improving the fire resistance of PVC membrane structural materials and the strength of PVC membrane structural materials.

1、 PVC blister films may wrinkle during production due to the following reasons:

The spacing between narrow and long workpieces is too small

The edges and corners around the base plate are not chamfered

The spacing between the transverse and longitudinal directions of the workpiece is not in a straight line, resulting in increased resistance

The temperature set by the machine is too high

The time for the machine to set its own pressure is too long

2、 PVC blister films may be blanched during production due to the following reasons:

The temperature set by the machine itself is too high

The time for the machine to set its own pressure is too long

3. Improper setting of its line type
