How to judge the quality of plastic coated cloth?

PVC plastic coated cloth has the properties of waterproof, mildew proof, wear resistance, durability, cold resistance and aging resistance. It is widely used in many fields with its superior performance. However, there are many tarpaulin manufacturers in the market. How should enterprises judge the quality of PVC plastic coated cloth? good or bad? The main component of PVC plastic coated cloth is polyvinyl chloride (ie PVC). PVC canvas processing adds some auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process to enhance its heat resistance, toughness, ductility, etc. It is used for car tarpaulins, train covers, ship covers, open-air freight yard covers, industrial and agricultural fields, etc. Its quality is mainly judged from the following points: PVC plastic coated cloth Appearance: excellent PVC plastic coated cloth The color is good and bright; one side is flat and smooth, and the other side has some granular objects, indicating that the resin composition is properly added and the temperature is suitable; no pinholes, high resin density, good aging resistance, and long service life. Tensile force: According to different processes, the canvas is very careful in the material ratio, and the matching is very suitable, so that the damage to the cloth blank is small, and the tensile force will be better; the warp and weft density of the yarn is high, and the tensile force is good. Waterproof performance: The waterproof performance is good, the glue is good, and the canvas will not have pinholes, indicating that the production material is very good. In the addition of materials, there are many resin components, high density and good waterproof performance. Hand feel: It feels very soft, although the thickness seems to be average, but in fact the thickness has reached the requirement, just because the resin composition is high and the processing technology is good, so it feels very soft and does not feel rough. Environmental protection performance: PVC plastic coated cloth is based on polyester filament, with PVC double-sided coating on the surface, selected high-quality environmentally friendly resin, smooth surface, bright color, waterproof, fireproof, anticorrosion, mildewproof, cold resistance, high temperature resistance , Anti-ultraviolet, anti-aging and other properties. Production process: PVC plastic coated cloth is produced by vertical machine, and vertical machine is used for mechanical production. Straighten the cloth and put it into the raw material box and pull it out. Scrape straight through the machine with a knife, scrape it with a knife and then dry it in a dryer, trim the edges, divide it into circles, and pack it. There are two types of dryers, one is electric burning and the other is boiler. The vertical machine has high requirements on raw materials, and the raw materials must have a certain purity. The PVC canvas produced by the vertical machine is often slightly more expensive, and the purity of the canvas product is also high. At present, many manufacturers in the market can provide PVC plastic-coated cloth, but due to the differences in material, process and cost, the quality of PVC plastic-coated cloth on the market is uneven, so enterprises must make comparisons and judgments. Wantai, as a domestic professional The tarpaulin manufacturer currently offers various types of high-quality PVC plastic-coated cloth at a discount.
