PTFE is currently the largest amount of fluoroplastics in the variety, accounting for about 60% of its total demand, its excellent performance, trusted by users. The application of other fluoroplastics in semiconductor, medical, wire coating and other fields is also expanding.Recycling fluoroplastics(Teflon)The purpose of can be summarized:
The use of its drug-resistant plastic in the drug-resistant applications have long been not limited to the manufacture of seals, gaskets, pipe fittings, in other parts that require corrosion resistance (such as pipes) on the star is also increasing. With the progress of raw materials and processing technology, the molding method of recycled fluoroplastics has expanded the range of factory choices: such as injection molding can greatly improve production efficiency, cutting process can be used in small batch production, PTFE bonding and welding technology development makes it possible to manufacture large storage tanks and equipment linings, FEP powder spraying process makes processing more flexible and convenient. In the semiconductor production process, anti-corrosion, anti-pollution has been more use of fluoroplastics.
2. The friction coefficient of PTFE in the field of machinery industry is small, and its static friction coefficient is lower than that of dynamic friction coefficient. It can be used in the field of low speed and high load, such as in civil engineering, chemical engineering, bridge and other structural parts, which can solve the expansion problem caused by thermal expansion and vibration. Specific applications are:
(1) anti-pollution machinery (such as textile, paper, pharmaceutical, food machinery) bearing sleeve;
(2) conveying alkali, solvent and other non-lubricating liquid machinery (such as mixer, dyeing machine, pump);
(3) in acid, alkali and other corrosive environment (such as electroplating bath chemical equipment) work under the sleeve;
(4) Prohibited oil lubrication (such as oxygen making equipment);
(5) Yuan oil lubrication (such as ultra-low temperature refrigerators, liquid fuel pumps);
(6) Sliding parts working in an environment with poor oil lubrication effect (adding high-temperature dryer, furnace-end platform, furnace conveyor belt);
(7) Sliding member (movable support) at low speed and high load.
3. Fluoroplastics in the electrical field are flame retardant materials. The critical oxygen index is high and corrosive, which can be used as the insulation layer of the wire.
The insulation resistance and insulation strength of the ETFElPvDF are high, and the mechanical strength is also excellent. QT is used for computer and communication cable. The use of its weather resistance, radiation resistance and other characteristics can be used in oil wells and nuclear reactors small cable. Recycled fluoroplastics manufacturers use their low relative dielectric constant and dielectric loss at high frequency can be used in communication equipment, high-frequency electrical instruments, PTFE and carbon black, carbon fiber and other conductive substances can be mixed as anti-static materials and heating element materials. PvDF can also be made into piezoelectric components for the radio industry and the instrumentation industry.
4. Non-stick: Recycled fluoroplastics manufacturers can use the non-stick nature of fluoroplastics to manufacture kitchen equipment (such as non-stick pans, snack molds), exterior wall coatings for high-level buildings, foam plastic molding molds, copier rollers, etc. In addition, in artificial blood vessels, heart valve and other medical soil engineering materials, gas separation membrane, waterproof breathable composite fabric and other aspects of the use is also increasingly widespread.
