What is a PVC knife scraping时间:2023-06-07 PVC knife-scraped coated fabric is a PVC coated fabric produced by a special knife-scraping process. It uses high-strength polyester fiber (or glass fiber) as the base fabric. The PVC paste resin is evenly scraped on the substrate through a multi-coating process, and then plasticized and shaped at high temperature. It is characterized by thick coating, high strength, and stable performance. It is a kind of high-end PVC tarpaulin. Features of PVC knife-scraped cloth Super wear resistance The surface PVC coating is thick, and the scratch resistance is 2-3 times that of ordinary PVC tarpaulin, which is suitable for high-frequency friction scenes (such as truck cover). High waterproofness The coating has no pores, the water pressure withstands >5000mm water column, and the seams are welded by hot air, which is completely leak-proof. Anti-ultraviolet Add double UV absorber, outdoor service life is 8-15 years, not easy to brittle and fade Resistant to extreme temperatures -40℃~+80℃ maintains flexibility (no hardening at low temperature, no adhesion at high temperature). Flame retardant optional Customizable B1 grade flame retardant Main applications High-end logistics: container tarpaulins, railway freight covers (long-term friction resistance required).Construction field: stadium roofs, membrane structure buildings (high strength and weather resistance requirements).Environmental protection projects: sewage treatment pool covers, landfill anti-seepage (chemical corrosion resistance).Special vehicles: military awnings, explosion-proof transport vehicle covers (tear resistance + flame retardant).Outdoor advertising: large-scale inkjet substrates (excellent surface flatness and strong ink absorption). PVC knife-coated cloth is a representative of industrial-grade protective materials. With its advantages of ultra-thick coating, extreme durability, and full environmental adaptability, it is widely used in scenes with strict performance requirements. Although the cost is high, the long-term cost performance is significantly better than ordinary PVC tarpaulins. |
