1. appearance: good color, shiny and reflective; One side is flat and smooth, and there are some granular objects on the other side, which indicates that the resin composition is properly added and the temperature is appropriate; No pinhole, high resin density, good aging resistance and long service life.
2. tension: according to different processes, the canvas keeps improving in the material ratio, so that the damage to the cloth blank is small, and the tension will be better; The higher the warp and weft density of the yarn, the stronger the tensile force.
3. waterproof performance: 100% waterproof performance. With good colloid, the canvas will not have pinholes. It is a high-quality production material. Material addition, resin composition and density all determine the performance of PVC waterproof cloth.
4. feel: it feels very soft. Although the thickness feels average, the thickness actually meets the requirements. It is only because the resin composition is high and the processing technology is good. Therefore, it feels very soft and will not feel rough.
PVC tarpaulin production process:
The vertical machine is used for production. The vertical machine is used for mechanical production. The cloth is straightened and pulled out into the raw material box. The colloidal materials adhered to the tarpaulin are high-purity PVC materials. Then both sides are straightened and scraped with a knife. After scraping with a knife, the cloth is dried in a dryer, cut edges, divided circles and packed. There are two types of dryers, one is electric and the other is boiler. The vertical machine has high requirements for raw materials, which must have a certain purity. PVC canvas produced by vertical machines is often slightly more expensive, and the purity of canvas products is also high.
Environmental protection performance of PVC tarpaulin:
With polyester filament as the base cloth, the surface is PVC double-sided coating, and high-quality environmental protection resin is selected. The surface is bright and clean, and the color is bright. It has the properties of waterproof, fire prevention, corrosion prevention, mold resistance, cold resistance, high temperature resistance, ultraviolet resistance, aging resistance, etc;
PVC tarpaulin product features:
Waterproof, sunscreen, mildew proof, reinforced silk production, tear resistance, cold resistance, high temperature resistance, etc;
