Among them, filling modification is a simple and effective method, which can not only maintain its advantages, but also use the compound effect to improve and overcome the defects of pure PTFE and improve its comprehensive performance.
Generally, there are four basic principles for selecting the filler: The filler is stable under sintering conditions of 380 ~ 400 cC, and is not compatible with or with PTFE The contacted metal or fluid reacts; ②The particle size is small and can be mixed evenly with PTFE powder; ③The filler does not absorb moisture and will not cluster by itself under sintering conditions; ④It can improve the mechanical strength and wear resistance of PTFE or improve Thermal conductivity, reduction of linear expansion coefficient, etc.
However, its low strength, wear resistance, creep resistance, and poor thermal conductivity have limited its wide application. The performance of the modified PTFE composite material is closely related to the type, content and molding process of the filler.
At present, in order to improve the Toaster Bag Manufacturers mechanical properties of PTFE composite materials, modification methods such as filling modification, surface modification and blending modification are usually used to meet people's requirements.PTFE is a high-molecular polymer with excellent performance, and its applications involve aerospace, petrochemical, machinery, electronics, construction, light textile and other industrial sectors. Adding different fillers to PTEF can significantly improve its tensile properties, impact properties, hardness or wear resistance
Megosztás a facebookonIt can withstand high temperature to 300°C in a short time, and generally can be used continuously between 240°C and 260°C. Under a certain load, it has the dual advantages of wear resistance and non-sticking. After Teflon spraying, the unique insulation and anti-static properties are widely used in the electronics industry.Teflon spray high-performance special coating is a fluorine coating based on polytetrafluoroethylene resin, the English name is Tefion.
After the inner wall of the bearing is treated, it has self-lubricating and wear resistance 【Corrosion toaster bags resistance application】[Resistant to high and low temperature applications] Teflon is hardly corroded by chemicals and can protect parts from any kind of chemical corrosion. (all are the transliteration of Teflon). It has remarkable thermal stability. Short downtime, saving working hours and improving work efficiency [Teflon wear resistance] It has excellent wear resistance under high load. It can work at freezing temperature without embrittlement and does not melt at high temperature.
[Electrical insulation application] After being coated with Teflon special industrial coating, it has good insulation and high resistivity on the surface, which can play an anti-static effect. Teflon spray coating is a rare high-performance coating that combines heat resistance, chemical inertness and excellent insulation stability and friction. It has a comprehensive advantage that other coatings can’t compete.
It has excellent chemical stability, excellent non-stick characteristics, and high operating temperature. Teflon spray is divided into several basic types: PTFE, FEP, PFA, ETFE: 1.html Teflon coating, Teflon coating,. Teflon spray has excellent heat resistance and low temperature resistance. Teflon sprayed PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260°C, with a high operating temperature of 290-300°C, extremely low friction coefficient, good wear resistance and excellent chemistry stability. (In addition, there are special coatings, which can make the coating conductive).
Its application flexibility makes it Can be applied to almost all shapes and sizes of products. It does not stick to water or oil, and it is not easy to stick to solutions such as sticky during production operations. 200°C.kytfl. Teflon spray ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene. The advantage of PFA is that it has a higher continuous use temperature of 260°C, stronger stiffness and toughness, and is especially suitable for anti-sticking and chemical resistance applications under high temperature conditions.
A small amount of dirt can be removed by simply wiping. 3. Because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon spray, etc. 2. Teflon sprayed PFA: PFA (perfluoroalkyl compound) non-stick coating melts and flows during baking to form a non-porous film like FEP. The resin is a tough fluoropolymer that can form a highly durable coating with excellent chemical resistance and can be used in Work continuously at 150°C
