PVC tarpaulin has the advantages of excellent waterproof, anti-aging, anti-static and tear resistance. It is a very popular protective cloth at present and is widely used in daily life, industrial production and other fields. The production process and application characteristics of cloth!
PVC tarpaulin
Production technology of PVC tarpaulin:
It is produced by vertical machinery, straightened by vertical machinery, put into the raw material box and pulled out. The colloidal material on the cover is a high-purity polyvinyl chloride material, and then straightened on both sides, scraped with a knife, dried with a knife, trimmed, divided into circles, and packaged. There are two types of dryers, one is electric burner 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 tarpaulin product has high purity.
Production process and characteristics of PVC tarpaulin:
Appearance: good color, bright reflection; one side is flat and smooth, and the other side has some granular objects, indicating that the resin composition is appropriate and the temperature is suitable; no pinholes, high resin density, good aging resistance, and long service life.
Stretching: According to different processes, the canvas is made with excellence in the material ratio, so that the damage to the fabric is less, and the stretching ability will be better; the higher the warp and weft density of the yarn, the stronger the stretching ability.
Waterproof performance: 100% waterproof performance, good glue, no pinholes in canvas, high quality production materials. Material addition, resin composition and density determine the performance of PVC tarps.
Feeling: It is very soft to the touch, 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, it feels very soft and does not feel rough.
Environmental performance: Polyvinyl chloride tarpaulin is based on polyester filament, the appearance is PVC double-sided coating, high-quality environmentally friendly resin is selected, the surface is smooth, the color is bright, and it is waterproof, fireproof, anticorrosion, mildewproof, cold resistance High temperature resistance, anti-ultraviolet, anti-aging and other properties;
