Features of this section
Polyvinyl chloride resin
(1) PVC general soft products
It can be extruded into hoses, cables, wires, etc. using an extruder; it can be made into plastic sandals, soles, slippers, toys, auto parts, etc. by using injection molding machines with various molds.
(2) PVC film
After PVC is mixed with additives and plasticized, a three-roller or four-roller calender is used to make a transparent or colored film with a specified thickness. The film is processed in this way to become a rolled film. It can also be processed by cutting and heat-sealing packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. Wide transparent films can be used for greenhouses, plastic greenhouses and mulch films. The biaxially stretched film is heat shrinkable and can be used for shrink packaging.
(3) PVC coated products
Substrate-made artificial leather is made by coating PVC paste on cloth or paper, and then plasticizing it above 100 degrees Celsius. It can also be rolled by rolling PVC and auxiliary into a film, and then laminated with the substrate. The artificial leather without substrate is directly rolled into a soft sheet of a certain thickness by a calender, and then pressed into a pattern. Artificial leather can be used to make suitcases, bags, book covers, sofas, and car cushions, as well as floor leather, which is used as flooring materials for buildings.
(4) PVC foam products
When soft PVC is mixed, a suitable amount of foaming agent is added to form a sheet, which is foamed into foam plastic, which can be used as foam slippers, sandals, insoles, and shock-absorbing cushioning packaging materials. It can also be made into low-foam rigid PVC sheets and profiles with an extruder base, which can be used as a substitute for wood and is a new type of building material.
(5) PVC transparent sheet
PVC is added with an impact modifier and an organotin stabilizer. After mixing, plasticizing and calendering, it becomes a transparent sheet. It can be made into thin-walled transparent containers or used in vacuum blister packaging by thermoforming. It is an excellent packaging material and decorative material-such as moon cake packaging boxes.
(6) PVC paste resin
Disperse PVC in a liquid plasticizer and swell and plasticize it to form a plastisol. Generally, emulsion or micro-suspension resin is used. Stabilizers, fillers, colorants, etc. need to be added. After sufficient stirring, deaeration, mix It is made into PVC paste, and then processed into various products by feeding, dipping, casting or slush molding. Such as hangers, tool handles, Christmas trees, etc.
(7) PVC rigid boards and plates
Stabilizers, lubricants and fillers are added to PVC. After mixing, hard pipes, shaped pipes, corrugated pipes of various calibers can be extruded with an extruder, and used as sewer pipes, drinking pipes, wire sleeves or stair handrails. . The rolled sheets can be laminated and hot pressed to produce hard boards of various thicknesses. The board can be cut into the desired shape, and then welded with hot air using PVC welding rods to various chemical resistant storage tanks, air ducts and containers.
(8) PVC other
Doors and windows are assembled from hard shaped materials. In some countries, it has occupied the door and window market together with wooden doors, windows and aluminum windows; wood-like materials, steel building materials (north, seaside); hollow containers.
PVC is a polyvinyl chloride plastic with bright color, corrosion resistance, and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process, its products generally do not store food and drugs.
PVC is actually a vinyl polymer. Simply put, an aqueous salt solution undergoes chemical decomposition under the action of an electric current. This process produces chlorine, caustic soda and hydrogen. Refining, cracking petroleum or gasoline can produce ethylene. When chlorine and ethylene are mixed, dichloroethylene is produced; dichloroethylene can be converted to produce chlorinated vinyl, which is the basic component of polyvinyl chloride. The polymerization process links the chlorinated vinyl molecules together to form a polyvinyl chloride chain. The polyvinyl chloride produced in this way was in the form of a white powder. It cannot be used alone, but can be mixed with other ingredients to produce many products.
