Main uses of polyvinyl chloride (pvc)

2019-07-10 11:40:47

1. Polyvinyl chloride profile

Profiles and profiles are the area of my country's PVC consumption, accounting for about 25% of the total PVC consumption. They are mainly used to make doors and windows and energy-saving materials, and their application is still growing significantly across the country. In developed countries, the market share of plastic doors and windows is also the highest, such as Germany at 50%, France at 56%, and the United States at 45%.

2. Polyvinyl chloride pipe

Among many polyvinyl chloride products, polyvinyl chloride pipes are its second largest consumption area, accounting for about 20% of its consumption. In my country, polyvinyl chloride pipes are developed earlier than PE pipes and PP pipes, with more varieties, excellent performance, and a wide range of applications, and occupy an important position in the market.

3. Polyvinyl chloride film

The consumption of PVC in the field of PVC film ranks third, accounting for about 10%. After PVC is mixed with additives and plasticized, a three-roll or four-roll calender is used to make a transparent or colored film with a specified thickness. The film is processed in this way to become a calendered film. It can also be cut and heat-sealed to process packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. The wide transparent film can be used for greenhouses, plastic greenhouses and mulching films. The biaxially stretched film has the characteristics of heat shrinkage and can be used for shrink packaging.

4. PVC hard materials and plates

Stabilizers, lubricants and fillers are added to PVC. After being mixed, the extruder can be used to extrude hard pipes, special-shaped pipes and corrugated pipes of various calibers, which can be used as sewer pipes, drinking water pipes, wire casings or staircase handrails. . The calendered sheets are overlapped and hot pressed to make hard plates of various thicknesses. The plate can be cut into the required shape, and then welded with hot air with PVC welding rod to form various chemical resistant storage tanks, air ducts and containers.

5. PVC general soft products

The extruder can be used to squeeze into hoses, cables, wires, etc.; the injection molding machine can be used with various molds to make plastic sandals, shoe soles, slippers, toys, auto parts, etc.

6. Polyvinyl chloride packaging materials

Polyvinyl chloride products are mainly used for packaging in various containers, films and rigid sheets. PVC containers are mainly used to produce mineral water, beverages, cosmetics bottles, and are also used for packaging refined oil. PVC film can be used for co-extrusion with other polymers to produce low-cost laminated products and transparent products with good barrier properties. Polyvinyl chloride film can also be used for stretch or heat shrink packaging for packaging mattresses, cloth, toys and industrial goods.

7. Polyvinyl chloride wall panels and floors

Polyvinyl chloride wall panels are mainly used to replace aluminum wall panels. Except for a part of PVC resin, the other components of PVC floor tiles are recycled materials, adhesives, fillers and other components, which are mainly used on the ground of airport terminals and other hard ground.

8. Polyvinyl chloride daily consumer goods

Luggage bags are traditional products made by the processing of polyvinyl chloride. Polyvinyl chloride is used to make all kinds of imitation leather, used in luggage bags, sports products, such as basketball, football and rugby. It can also be used to make belts for uniforms and special protective equipment. Polyvinyl chloride fabrics for clothing are generally absorbent fabrics (without coating), such as ponchos, baby pants, imitation leather jackets and various rain boots. Polyvinyl chloride is used in many sports and entertainment products, such as toys, records and sports goods. Polyvinyl chloride toys and sports goods have a large growth rate. They have an advantage due to their low production cost and easy molding.

9. PVC coated products

Artificial leather with a backing is made by coating PVC paste on cloth or paper, and then plasticizing it at a temperature above 100°C. It is also possible to calender PVC and additives into a film, and then press it with the substrate. Artificial leather without a substrate is directly calendered by a calender into a soft sheet of a certain thickness, and then the pattern is pressed. Artificial leather can be used to make suitcases, purses, book covers, sofas and car cushions, etc., as well as floor leather, used as floor coverings for buildings.

10. PVC foam products

When mixing soft PVC, add an appropriate amount of foaming agent to make a sheet, which is foamed into foam plastic, which can be used as foam slippers, sandals, insoles, and shock-proof cushioning packaging materials. The extruder can also be used to form low-foaming hard PVC boards and profiles, which can replace wood and is a new type of building material.

11. PVC transparent sheet

The impact modifier and organotin stabilizer are added to PVC, and it becomes a transparent sheet after mixing, plasticizing and calendering. Thermoforming can be made into thin-walled transparent containers or used for vacuum blister packaging. It is an excellent packaging material and decorative material.

12. Other

Doors and windows are assembled with hard profiled materials. In some countries, it has occupied the door and window market together with wooden doors, windows, aluminum windows, etc.; wood-like materials, steel-based building materials (northern, seaside); hollow containers.

The virtual circuit is one of the services provided by the packet switching network (the other is the datagram service). Simply put, it is to establish a virtual logical connection between user hosts through the internal control mechanism of the network, and to ensure the transmission of information on it. The correctness and sequence of packets, the establishment and removal of virtual circuits before and after communication. A virtual circuit is a virtual circuit that is established when the network is initialized, and the virtual circuit is always maintained. Both X.25 network and B-ISDN provide PVC services. PVC plastic bags are generally prohibited.
