Tarpaulin manufacturers teach you how to distinguish three-proof tarpaulin and five-proof tarpaulin

      The plastic-coated high-strength polyester waterproof cloth of PVC three-proof tarpaulin is based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin and added with speed-increasing agent, anti-fungal agent, anti-aging agent, agent, etc. A variety of chemical additives, plasticized at high temperature. It is waterproof, anti-mildew, and has a special surface treatment for non-slip effect. It is an internationally popular waterproof cloth with a very large width, reaching 2 meters wide. When processing the finished product, it can reduce seams and improve quality. It can be heat-sealed and spliced. Worry about water leakage in the pinhole. It also produces products with different functions, different colors and different thicknesses according to user needs.

      Tarpaulins are widely used in transportation, logistics, construction sites, agricultural granaries and other fields due to their good anti-aging and tear-resistant properties. Tarpaulin has a wide range of use, which brings great convenience to people's production and life. Tarpaulins are divided into three levels according to their needs: ordinary tarpaulins, three-proof tarpaulins, and five-proof tarpaulins. Among them, what kind of tarpaulin are "three-proof tarpaulin" and "five-proof tarpaulin"?

      Here is a detailed description of the tarpaulin-related knowledge for you. "Three defenses" have different interpretations in different fields. Among them, Baidu Baike's interpretation of "three defenses" refers to "anti-nuclear weapons, anti-biological weapons, and anti-"chemical weapons." In the electronics industry, "three defenses" refer to " Anti-mold, anti-moisture, and anti-salt fog"; in the agricultural field, three preventions refer to "drought prevention, flood prevention, and wind prevention"; in industry, three preventions refer to "antifreeze, anti-skid, and anti-poisoning"; in the construction industry, it refers to The "waterproof, fireproof, and shockproof" three-proof tarpaulin is different from the "three-proof" mentioned above. The three-proof tarpaulin mainly refers to the anti-aging, waterproof, and mildew-proof; the five-proof tarpaulin is also in addition to the three-proof It must be fireproof and anti-corrosion. It is required that the water pressure resistance value is ≥2000MM water column, the cold resistance temperature is -20°C, the mildew resistance test is--grade, and the flame retardant grade is above V-2. This is the main three-proof tarpaulin and non-proof tarpaulin Several requirements. Due to the high quality requirements for three-proof tarpaulin and five-proof tarpaulin, PVC material is mainly used, and users can also choose the grade of tarpaulin according to their needs. The following is the current PVC three-proof tarpaulin Main application areas:

1. Freight tarpaulins for cars and trains;

2. It is used to cover the stacks in the warehouse;

3. Build temporary granaries and cover all kinds of crops in the open air;

4. Temporary sheds on various construction sites such as construction sites, electric power construction sites, etc.;

5. Outer sheath of various machinery and equipment;
