Polyvinyl chloride resin is a typical product of thermoplastic general purpose plastics. It is formed by polymerization of vinyl chloride (CH2 = CHCI). There are two kinds of soft resins with plasticizers (phthalates) and hard resins without plasticizers. The specific gravity of hard PVC is between 1.35 and 1.45, and the specific gravity of soft PVC is 1.16 to 1.35. The heat resistance temperature is only 49 ?? C ~ 71 ?? C and 66 ?? C ~ 79 ?? C respectively, which are very low, not easy to burn, and good electrical insulation performance. Often used in wire sheath insulation material, film, sheet, vinylon brick, LP record, pipe, etc., in addition to the car mat, raincoat and coating seasoning. Due to the poor heat resistance and weather resistance of the resin, the performance will deteriorate and yellowing under the action of ultraviolet light and heat, and various improvements are being made.
Polyvinyl chloride can also form copolymers with other resins. For example, the copolymer generated with polystyrene can improve the impact resistance strength; The copolymer formed with polypropylene can also improve the impact strength; The copolymer formed with acrylonitrile can improve the tensile strength and be used as the raw material of synthetic fiber. The copolymer formed with Vinylnylon acetate can reduce the melting viscosity and improve the formability of the material. The biggest problem with PVC is the disposal of its waste, which releases chlorine gas when it is burned.
Polyvinyl chloride has abundant raw materials, low price, good performance and wide use. When PVC is used as a plastic, various additives are often added according to different performance purposes, such as stabilizers, plasticizers, lubricants, fillers and pigments. Hard PVC plastic can manufacture a variety of devices and profiles, often processed chemical production of corrosion-resistant pipes, valves, ventilation equipment, as well as window frames, furniture, agricultural products. The plasticized soft PVC can be used for wire, cable and hose. The rolled film can be made into daily necessities such as raincoats, toys and used as packaging materials and agricultural heating shed covering materials. Foam PVC can be used to make plastic floors, soles, life-saving equipment and insulation and sound insulation materials. PVC foam leather can be used as a substitute for leather, imitation leather jacket, sandals and so on. PVC thermoplastic elastomer can be used for sealing materials such as car shields, bushings and container doors. PVC fiber (also known as chlorlon) can be made of work clothes, filter cloth, carpet, tent, etc., made of knitted underwear has a certain auxiliary effect on rheumatoid arthritis.
