pvc tarpaulin has excellent mildew resistance, obvious waterproofness, more waterproof than other canvases, good low-temperature flexibility, high strength, strong tensile force, relatively light and other characteristics; it is very versatile, such as foreign trade, grain storage, oil fields, and docks. , Tents, drilling tower clothing, railway and road transportation, warehousing, coal mines, open-air cargo yards and other canvas products. So how to judge the quality of pvc tarpaulin when buying?

1. Appearance. Excellent pvc tarpaulin has good color and luster; one side is flat and smooth, and the other side has some granular objects, indicating that the resin component is added properly and the temperature is right; there are no pinholes, the resin has high density, good aging resistance, and long service life.

2. Pulling force. According to different processes, pvc tarpaulin is very careful in the material ratio, and the matching is very suitable, so that the damage to the fabric is less, the better the tension will be; 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 quality is good, and the pvc tarpaulin will not appear pinholes, indicating that the production material is very good. In the addition of materials, PVC has many components, high density and good waterproof performance.

4. Hand feeling. It feels very soft. Although it feels normal in thickness, the thickness has actually reached the required thickness. It is only because of the high resin content and good processing technology, so it feels very soft in the hand and does not feel rough.

5. Production process. The pvc tarpaulin is produced by a vertical machine, which is mechanically produced by a vertical machine. The cloth is straightened into the raw material box and pulled out. The glue material on the tarpaulin is a high-purity PVC material, and both sides are straightened by the machine knife. Scrape, scrape with a knife and then go through a dryer to dry, trim, divide, and pack. There are two types of dryers, one is to use electricity and the other is to use a boiler. Vertical machines have high requirements for raw materials and must have a certain degree of purity for raw materials. The pvc tarpaulin produced by the vertical machine is usually slightly more expensive, and the purity of the canvas product is also high.

6. Environmental performance. pvc tarpaulin uses polyester filament as the base fabric, the exterior is PVC double-sided coating, the selection of high-quality environmentally friendly resin, the surface is smooth, the color is bright, it is waterproof, fireproof, anti-corrosion, anti-mildew, cold, high temperature, anti-ultraviolet, and anti-corrosion. Aging and other properties.
