Pvc material has good electrical insulation properties, can be used as low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release HCL gas, so that polyvinyl chloride color, so its application is narrow, the use of temperature is generally between -15 to 55 degrees. The following small series for everyone to introduce pvc is what material knowledge. What is PVC material? The English name of pvc is abbreviated as poly vinyl chloride (PVC molecular structure). In general, our common PVC is a kind of plastic decoration material. Its chemical name is polyvinyl chloride. It consists of an amorphous thermoplastic resin made by polymerizing vinyl chloride monomers plus certain additives (such as stabilizers, lubricants, fillers, etc.). It has mechanical properties, strong acid and salt resistance, and low softening point. Chemical stability. Commonly used in the production of thin plates, wire, cable insulation, seals and other items. The essence of PVC is a vacuum-absorbing film, which is used for surface packaging of various types of panels. Therefore, it is also known as a decorative film, attached film, and is used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for the largest proportion, which is 60%, followed by the packaging industry, as well as other small-scale applications. Pvc types: According to the different hardness, pvc is divided into hard pvc and soft pvc two. 1, soft pvc Soft pvc contains softeners that tend to become brittle and difficult to store, so its range of use is limited. Common soft pvc is generally used in the floor, ceiling and leather surface. 2, hard pvc Also known as UPVC, or PVC-U products. Hard PVC does not contain softeners, so it has good flexibility, easy molding, is not brittle, non-toxic and non-polluting, and has a long storage time. Therefore, it has great development and application value. Its wide range of applications: pipeline industry, water supply and drainage, flame retardant electric cable bushings, electrical appliances, flame-retardant switch housings, sockets, profiles, steel, some fenders, bumpers and so on. Pvc application: Compared with Kimura and steel, PVC has the advantages of high elasticity, high cold strength, wear resistance, and good finish. Therefore, the proportion of PVC in the world is approximately 65% ​​for building plastics, 8% for packaging, 7% for electrical and electronics, and furniture. And decoration accounted for 5%, the general consumption of 4%, and the other 11%. Due to its high chemical stability, it can be used to produce anti-corrosion pipelines, pipe fittings, oil pipelines, centrifugal pumps and blowers. Polyvinyl chloride hard plates are widely used in the chemical industry to make various tank linings, building corrugated boards, door and window structures, wall decorations and other construction materials. Due to its excellent electrical insulation properties, it can be used in electrical and electronic industries for the manufacture of plugs, sockets, switches and cables. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather! Polyvinyl chloride has high mechanical strength and good corrosion resistance. It can be used to produce exhaust gas detoxification towers and gas liquid transport pipes in chemical, textile and other industries. It can also be used to make storage tanks, centrifugal pumps, ventilators and joints instead of other corrosion resistant materials. When the plasticizer is added in an amount of 30% to 40%, a soft polyvinyl chloride is obtained, which has a high elongation rate, a soft product, good corrosion resistance and electrical insulation, and is often used as a film. Industrial packaging, agricultural education and daily raincoats, tablecloths, etc., can also be used to make acid and alkali resistant hoses, cable wrappers, and insulation layers. PVC material is widely used, with good processing performance, low manufacturing cost, corrosion resistance, good insulation and other characteristics, mainly used for production: pvc cards, pvc OEM, pvc wire, pvc curtains, pvc plastic welded wire mesh, pvc foam Boards, pvc ceilings, pvc pipes, pvc skirtings, etc., as well as threading pipe, cable insulation, plastic doors and windows, plastic bags and so on. PVC products are everywhere in our daily life. PVC is used to make all kinds of imitation leather for luggage, sports products such as basketball, football and rugby. It can also be used to make belts for uniforms and special protective equipment. Pvc board: The PVC board is a sheet made of PVC as a raw material and has a honeycomb mesh structure in cross section. According to the production process can be divided into PVC crust foam board and PVC free foam board. PVC foam board is widely used in furniture, cabinets, bath cabinets, display racks, etc. due to its features such as anti-corrosion, moisture-proof, mildew-proof, non-absorbent, drillable, sawable, planable, easy thermoforming, and thermal bending. Box core, indoor and outdoor decoration, building materials, chemicals and other areas of the board, advertising signs, printing, silk screen, inkjet, computer lettering, electronic instrumentation product packaging and other industries. PVC hard plastic board has excellent corrosion resistance, insulation, and a certain degree of mechanical strength; after the secondary processing can be made of sulfuric acid (hydrochloric acid) tank (tank box); medical empty needle rack, process frame; public Toilet water tanks; processing products of the template, decorative panels, exhaust ducts, equipment lining and other special-shaped products, containers. It is an ideal material for chemical, building materials, decoration and other industries. Pvc pipe: PVC pipe (UPVC pipe) PVC pipe is a PVC pipe that is first developed and applied by the combination of polyvinyl chloride resin and stabilizers, lubricants, etc., and hot extrusion. UPVC pipe has strong anti-corrosion ability, easy to bond, low price of PVC pipe and hard texture, but due to the seepage of UPVC monomer and additives, it is only suitable for the water supply system where the delivery temperature does not exceed 45°C. PVC floor: PVC flooring is a new type of lightweight floor decoration material that is very popular in the world today, also known as "lightweight floor materials." It is a popular product of Japan and Korea in Europe, America and Asia. It has become popular in foreign countries. It has entered the Chinese market since the early 1980s and has been widely recognized in large and medium-sized cities in China. It has been widely used, such as indoor homes and hospitals. , schools, office buildings, factories, public places, supermarkets, businesses, stadiums and other places. "PVC floor" refers to the floor made of PVC material. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw materials, and additives such as fillers, plasticizers, stabilizers, colorants, etc. are added to the sheet-like continuous substrate by a coating process or through calendering, extrusion or extrusion. Process production. Editor's summary: The above is the introduction of Xiaobian's knowledge of pvc material. More practical knowledge, please pay attention to Qijia information.
