One, the Chinese name of the PVC material is polyvinyl chloride;
Main uses
1. PVC profiles
Profiles, profiles is the largest field of PVC consumption in China, accounting for about 25% of the total consumption of PVC, mainly used for the production of windows and doors and energy-saving materials, and its application is still a relatively large increase in the national scope. In developed countries, the market share of plastic doors and windows is also high, such as Germany for 50%, France for 56%, the United States for 45%.
2. Polyvinyl chloride pipes
In many polyvinyl chloride products, polyvinyl chloride pipe is its second largest consumption area, accounting for about 20% of its consumption. In our country, PVC pipe is developed earlier than PE pipe and PP pipe, with many varieties, excellent performance, wide range of use, and occupies an important position in the market.
3. Polyvinyl chloride film
PVC film field of PVC consumption ranks third, accounting for about 10% or so. PVC and additives mixed, plasticized, using three-roller or four-roller calender to make the required thickness of transparent or coloring film, with this method of film processing, become calendered film. It can also be cut and heat-laminated to process bags, raincoats, tablecloths, curtains, inflatable toys and so on. Wide transparent film can be used for greenhouses, plastic greenhouses and ground cover. The bi-directionally stretched film can be used for shrink-wrapping due to its heat-shrinkage property.
4. PVC hard materials and sheets
PVC in the addition of stabilizers, lubricants and fillers, after mixing, with the extruder can be extruded in a variety of calibers of the hard pipe, profiled pipe, corrugated pipe, used as a downpipe, drinking water pipe, wire casing or staircase handrails. The calendered sheets are overlapped and hot pressed to make various thicknesses of rigid sheets. Sheet can be cut into the desired shape, and then use PVC welding rod with hot air welding into a variety of chemical-resistant storage tanks, air ducts and containers.
Two, pe material Chinese name for polyethylene;
Main uses
1, high-pressure polyethylene: more than half of the film products, followed by pipe, injection molding products, wire wrapping layer, etc.
Intermediate and low-pressure polyethylene: injection molding products and hollow products.
Ultra-high-pressure polyethylene: due to the excellent comprehensive performance of ultra-high polymer polyethylene, it can be used as engineering plastics.
2, printing: for water, oil and chemicals and other high performance product labels, Han Yuan printing often use this material in cosmetics, shampoo, washing and other daily-use chemical labels in the use of the process of moisture resistance, extrusion resistance requirements. Excellent flexibility, especially for plastic bags. It can also be used in cases where PVC labeling materials cannot be used due to environmental requirements.
3, processing: polyethylene can be used in blow molding, extrusion, injection molding and other methods of processing, widely used in the manufacture of film, hollow products, fibers and sundries.
Three, the Chinese name of the PP material is polypropylene;
Main uses
1, household appliances. Some of China's plastic raw materials manufacturers have developed a washing machine special material such as PP1947 series, K7726 series, etc., by the washing machine manufacturers welcome. Therefore, in the next few years should increase the development of PP special materials for household appliances, in order to meet the changing needs of the market.
2, plastic pipe: PP pipe is mainly used as agricultural water pipeline, but due to early product performance there are still some problems, the market failed to open. Reportedly, South Korea developed a high-pressure water supply pipe with no rules **** polypropylene PP-R112 new grade, the use of the pipe produced by the grade can be in 20 ℃ and 11.2MPa under ultra-high-pressure state of use for 50 years.
3, high-transparent materials: with the continuous improvement of people's standard of living, will inevitably bring in culture, entertainment, food, medical care, materials, home decorations, and other aspects of the different changes in the requirements and improve the market for many items more and more use of transparent materials. Therefore, the development of transparent PP special materials is a good development trend, especially the need for high transparency, good fluidity, molding fast PP special materials, in order to design and processed into people's favorite PP products.
Four, the Chinese name of the PC material is polycarbonate;
Main uses
1, optical lighting: used in the manufacture of large lampshades, protective glass, optical instruments, left and right eyepiece barrels, etc., but also can be widely used for transparent materials on the aircraft.
2, electronic and electrical appliances: polycarbonate is an excellent E (120 ℃) level insulating materials, used in the manufacture of insulated connectors, coil frames, tube holders, insulating bushings, telephone shells and parts, battery shells of the lamps and so on. Can also be used for the production of very high dimensional accuracy of the parts, such as optical disks, telephones, electronic computers, video recorders, telephone exchanges, signal relays and other communications equipment. Polycarbonate thin touch is also widely used as capacitors, insulated leather bags, audio tapes, color video tapes and so on.
3, mechanical equipment: used in the manufacture of a variety of gears, racks, worm gear, worm, bearings, cams, bolts, levers, crankshafts, ratchets, but also for some mechanical equipment shells, covers and frames and other parts.
4, medical equipment: cups, cylinders, bottles for medical purposes, as well as dental instruments, pharmaceutical containers and surgical instruments, and can even be used as artificial kidneys, artificial lungs and other artificial organs.
