Production process of PVC plastic coated cloth

There are two production processes for PVC plastic coated cloth. One is horizontal machine production, which is the kind of heavy-duty large cylinder. After the sheet is put into the material, it is placed on the belt and pressed and flattened by the bottom of the heavy-duty large cylinder. , then pull on the dryer to dry, then trim, divide and pack. One is vertical machine production, straightening the cloth into the raw material box and pulling it out. The glue material on the sheet is high-purity PVC material, and then both sides are straightened through the machine and scraped with a knife. After drying, it is dried in a dryer, trimmed, divided into circles, and packaged. There are two types of dryers, one is electric burning and the other is boiler. PVC plastic coated cloth is upgraded and improved on the basis of traditional oil wax canvas. It has the following characteristics: 1. Good waterproof performance, 100% waterproof; 2. High tensile strength, continuous pulling force in the warp and weft directions; 3. Very little water absorption, quick drying after rain, no weight gain; 4. Heat resistance Good performance, no effect at 70℃; 5. Good aging resistance, no hard cracking in summer with high temperature; no cracking in cold environment (-20℃) in winter (need to add special antifreeze); 6. Light weight , about 0.65kg per square meter; 7. Long service life, normal use can reach 2~3 years.
