I believe that many friends who work in transportation and cargo yards know about PVC coated cloth and PVC waterproof tarpaulin, because this is a cargo covering equipment that everyone in the industry must know. Because canvas can shelter from wind and rain, is durable, wear-resistant and environmentally friendly, logistics companies, storage terminals, factories, farms and most companies need to use it to cover cargo in large quantities. In recent years, PVC coated cloth has been widely used in car tarpaulins, ship tarpaulins, open-air cargo yard tarpaulins, train tarpaulins, construction site tarpaulins, crop tarpaulins, machine covers, outdoor camping tents, etc., and has a wide range of uses.
PVC coated cloth is a high-quality product among tarpaulins. It has excellent mildew resistance, obvious waterproofness, is more waterproof than other canvases, has good low-temperature softness, high strength, strong tensile strength, anti-corrosion, anti-aging, and relatively light characteristics; Adding method: heat sealing machine, sewing machine. To judge the quality of a piece of PVC coated cloth, focus on several points:
1. Appearance. Excellent PVC coated cloth has good color and is very bright; one side is flat and smooth, and the other side has some granular objects, which means that the resin component is added appropriately and the temperature is appropriate; there are no pinholes, the resin density is high, the anti-aging is good, and the service life is long.
2. Tension. According to different processes, the canvas is very careful in the material ratio and is matched appropriately, so that the damage to the cloth blank is small and the tension will be better; the warp and weft density of the yarn is high and the tension is good.
3. Waterproof performance. The waterproof performance is good, the glue is good, and the canvas will not have pinholes, which means that the production material is very good. In terms of material addition, the resin component is high, the density is high, and the waterproof performance is good.
4. Feel. It feels very soft. Although it feels that the thickness is average, the thickness has actually reached the requirement. It is just because the resin component is high and the processing technology is good, so it feels very soft and does not feel rough.
5. Production process. PVC coated cloth is produced by vertical machine. The cloth is straightened and put into the raw material box and pulled out. The glue material on the cloth is high-purity PVC material. Then both sides are straightened and scraped by the machine. After scraping, it is dried in the dryer, trimmed, divided and packaged. There are two types of dryers, one is electric burning and the other is boiler. The vertical machine has high requirements for raw materials and must have a certain purity. Often, PVC canvas produced by vertical machines is slightly more expensive, and the purity of canvas products is also high.
6. Environmental performance. PVC coated cloth uses polyester filament as the base fabric, with PVC double-sided coating on the surface. It selects high-quality environmentally friendly resin, has a smooth surface, bright colors, and has waterproof, fireproof, corrosion-resistant, mildew-proof, cold-resistant, high-temperature-resistant, UV-resistant, and aging-resistant properties.
