How to distinguish between good and bad tarpaulins?

Many ways to identify the quality of tarpaulins are for transportation. Friends in the freight yard all know PVC plastic-coated cloth and PVC waterproof tarpaulin, because this is the equipment that must be known in the industry. Because canvas has the characteristics of sheltering from wind and rain, durability, wear resistance, and environmental protection, most companies need a large amount of canvas to cover goods in logistics companies, storage terminals, factories, and farms. In recent years, PVC coated cloth has been widely used in automobile tarpaulin, ship tarpaulin, freight yard tarpaulin, train tarpaulin, construction site cloth, crop tarpaulin, machine cover, camping tent, etc., and has a wide range of uses.

PVC coated cloth is the best among tarpaulins. It has excellent mildew resistance, obvious water resistance, more waterproof than other canvases, good low temperature flexibility, high strength, strong tensile force, anti-corrosion, anti-aging, relatively light, etc.; adding method: heat sealing machine, sewing machine. To judge the quality of a piece of PVC plastic-coated cloth, there are mainly the following points:

1. Appearance. Excellent PVC coated cloth with good color; one side is flat and smooth, and the other side has granules, indicating that the resin components are properly added and the temperature is suitable. No pinholes, high resin density, good aging resistance and long service life.

2. Pull force. According to different crafts, the canvas is very particular about the material ratio, and the matching is very suitable, so that the less damage to the fabric, the better the tensile force; the yarn has a high warp and weft density and good tension.

3. Waterproof performance. The waterproof performance is good, the glue quality is good, and the canvas does not appear pinholes, indicating that the production material is very good. In terms of material, there are many resin components, high density, and good waterproof performance.

4. Feeling. Soft to the touch. Although the thickness seems average, the thickness has actually reached the required thickness. Just because the resin content is high and the processing technology is good, it feels very soft and does not feel rough.

5. Production process. PVC plastic-coated cloth is produced by vertical machine, and it is mechanically produced by vertical machine. Straighten the fabric and put it into the raw material box and pull it out. The glue material on the thatch is high-purity PVC material, and then both sides are straightened by the machine. Knife scraping, after knife scraping, it is dried, trimmed, divided, and packaged by a dryer. There are two types of clothes dryers, one is electric and the other is boiler. Vertical machines have high requirements on raw materials, which must have a certain purity. The PVC canvas produced by the vertical machine is often slightly more expensive, and the purity of the canvas products is also high.

Environmental performance. PVC coated cloth uses polyester filament as the base cloth, the appearance is PVC double-sided coating, high-quality environmental protection resin is selected, the surface is flat, the color is bright, waterproof, fireproof, anti-corrosion, mildew-proof, cold-resistant, high-temperature resistant, UV-resistant, anti-aging and other performance.
