Tips for choosing tarpaulin

     Tarpaulin (or waterproof cloth) is a kind of waterproof material with high strength, good toughness and softness. It is often used as canvas (canvas), polyester with polyurethane coating or polyethylene plastic.

     There are many kinds of tarpaulins. Each kind of tarpaulin is made of different materials and has different use effects. The tarpaulin is usually provided with solid grommets at the corners or edges to facilitate binding, hanging or covering with ropes.

     Because of its waterproof characteristics, it is often used in construction sites, chemical industry, grain rain proof, truck waterproof, etc. Because of its sunshade characteristics, it is often used for drying raw materials in factories and sunscreen in greenhouses.

     There are many national standards for tarpaulins. The quality requirements include chloride ion detection, quality detection, tension detection, fire rating detection, combustion performance detection, index detection, material detection, aging test, density detection, service life evaluation, etc. Take the packaging industry standard BB / t0037-2012 double coated PVC flame retardant waterproof cloth and tarpaulin as an example, and let you have a deeper understanding.

      Many people can't tell the difference between PE tarpaulin and PVC coated tarpaulin. Literally, PE and PVC are definitely different. The difference between these two kinds of tarpaulins will be explained in essence. PE: its chemical name is polyethylene. It is a semi crystalline thermoplastic material and is the material for manufacturing PE tarpaulin. What are the characteristics of PE? We have learned that polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance, good water absorption, good electrical insulation, can be used normally at - 70 to - 100 ° C, and has good chemical stability. HDPE (high density polyethylene) is generally used in the production of PE tarpaulin. This material has high service temperature, good hardness, mechanical strength and chemical resistance. Polyethylene is suitable for hollow blow molding, injection molding and extrusion of various products (hard), such as various containers, nets, packing belts, and can be used as cable coatings, pipes, profiles, sheets, etc.

      PE tarpaulin raw materials generally refer to color striped cloth. PE film is coated on both sides of PE woven cloth, and polypropylene woven cloth is also used. The production process is: wire drawing round woven cloth double-sided film coating. This kind of tarpaulin has poor waterproof performance. Generally, it cannot guarantee the waterproof performance after one use. The disadvantage is that it is easy to wear and tear. The advantage is that it is light in weight, clean and pollution-free. It is generally used for temporary stacking of goods to prevent rain and dust, and is not suitable for long-term use in the open air.

      PVC tarpaulin is a plastic coated high-strength polyester waterproof cloth, which is made of high-strength polyester canvas as the base cloth, coated with polyvinyl chloride (PVC) paste resin and added with various chemical additives such as accelerator, mildew inhibitor, anti-aging agent and antistatic agent, and plasticized at high temperature. It is waterproof, mold proof, cold resistant, aging resistant and antistatic; And the breaking strength, tear elongation and tear strength of this product are much better than the traditional tarpaulin; The appearance of the product is colorful and pleasing to the eye. The surface is specially treated for anti-skid effect. It is an internationally popular waterproof canvas with a large width. When processing finished products, it can reduce the seam and improve the quality. It can be heat sealed and spliced to avoid the worry of water leakage in sewing pinholes. And can produce products with different functions, different colors and different thicknesses according to user needs.

     There are many kinds of tarpaulins and their uses are also very wide. When purchasing tarpaulin products, consumers should pay attention to selecting products from regular manufacturers, and check the product implementation standards and corresponding test reports to prevent property loss caused by unqualified products purchased.
