Do you know the production process of PVC plastic coated cloth?1

The production process of PVC plastic-coated cloth, there are two kinds of PVC plastic-coated cloth production process, one is horizontal machine mechanical production, which is the kind of heavy-duty large cylinder, put the sheet cloth into the material and then put it on the belt. , pressed and flattened at the bottom of the heavy cylinder, then pulled into the dryer to dry, then trimmed, divided into circles, and packaged. 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.
