PVC tarpaulin has good rain resistance, pvc tarpaulin has good durability, and the aging resistance of pvc tarpaulin is much better than that of PP and PE tarpaulins. From the current point of view, such technical advantages are still trustworthy and are the key to bringing market sales. The quality is guaranteed, and the package service is provided within the stipulated time limit, and it can be replaced if there is a quality problem. The advantages that mechanization brings to the pvc tarpaulin factory will allow it to gain a foothold in the fierce market competition, bring more customers and bring more benefits to itself.
PVC is actually a kind of vinyl polymer, the main component is polyvinyl chloride (Polyvinylchloride, PVC), and its material is a non-crystalline material. In actual use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives. It has non-flammability, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
Polyethylene abbreviated as PE, it is a polymer of ethylene, non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, and good electrical insulation. It is suitable for packaging materials for food and medicine, making food utensils, medical equipment, and insulating materials for the electronics industry.
Polyvinyl chloride is abbreviated as PVC in English, which is a polymer of vinyl chloride. It has good chemical stability and is resistant to acid, alkali and some chemicals. It is resistant to moisture, aging, and flame retardant. The temperature cannot exceed 60℃ when it is used, and it will harden at low temperatures. Polyvinyl chloride is divided into soft plastic and hard plastic. The soft ones are mainly made into films, which can be used as packaging materials, rainproof products, agricultural seedling raising films, etc., and can also be used as insulation layers for cables and wires, and artificial leather products. Rigid ones are generally made of pipes and plates. The pipes are used as water pipes and pipes for transporting corrosion-resistant fluids. The plates are used as the lining and floor of various storage tanks.
PVC tarpaulin is non-toxic, while polyvinyl chloride monomers are highly toxic. Whether polyvinyl chloride products are toxic depends on whether the residual monomers in the polymerization process are removed to certain requirements, and on the other Whether the additives added during processing are toxic. For example, if the content of vinyl chloride monomer in PVC food cling film is too high, especially in high-temperature environments such as microwave ovens, it is easy to decompose substances that have carcinogenic effects on the human body; in addition, plasticizers and stabilizers for processing PVC cling film If the choice is not good, it is easy to cause certain harm to the human body.
