特种涂料 是以聚四氟乙稀为基体树脂的氟涂料,英文名称为Teflon,因为发音的缘故,通常又被称之为铁氟龙、铁富龙、特富龙、特氟隆等等(皆为Teflon 的译音)。 Teflon high-performance special coating is a PTFE coating based on polytetrafluoroethylene. The English name is Teflon. Because of its pronunciation, it is often called Teflon, Teflon, Teflon, and special Fluon and so on (both are transliterated by Teflon). Teflon (Teflon) coating is a unique high-performance coating, which combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has the comprehensive advantages that other coatings can't compete with. Its flexible application The nature makes it applicable to almost all shapes and sizes.

A、 PTFE、FEP、ETFE几种基本类型: Teflon is divided into several basic types: PF A, PTFE, FEP, ETFE:

1. Teflon PFA: PFA (perfluoroalkylate) non-stick coating, like FEP, melts and flows to form a non-porous film during baking. The advantage of PFA is that it has a higher continuous use temperature of 260 ° C and stronger rigidity. It is especially suitable for use in the fields of anti-sticking and chemical resistance under high temperature conditions.
聚四氟乙烯 )不粘涂料可以在260℃连续使用,具有最高使用温度290-300℃,极低的摩擦系数、良好的耐磨性以及极好的化学稳定性。 2. Teflon PTFE: PTFE ( polytetrafluoroethylene ) non-stick coating can be used continuously at 260 ° C, with a maximum use temperature of 290-300 ° C, extremely low friction coefficient, good abrasion resistance and excellent chemical stability Sex.
3. Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows to form a non-porous film during baking. It has excellent chemical stability and excellent non-stick characteristics. The maximum operating temperature is 200. ℃.
4. Teflon ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene. The resin is the toughest fluoropolymer. It can form a highly durable coating with excellent chemical resistance. Continuous working at 150 ° C.

After Teflon coating, it has the following characteristics:
化学腐蚀 1. Corrosion resistance: Teflon is hardly attacked by drugs and can protect parts from any kind of chemical corrosion .
2. Sliding property: Teflon coating has a low coefficient of friction. The friction coefficient changes when the load slides, but the value is only between 0.05-0.15.
3. Not sticky: Almost all materials are not bonded to the Teflon coating film. Very thin films also show good non-stick properties. 4. Heat resistance: Teflon coating film has excellent heat resistance and low temperature resistance. It can withstand high temperature to 300 ℃ in a short time, and can be used continuously between 240 ℃ ~ 260 ℃. It has significant thermal stability. It can work at freezing temperature without embrittlement and does not melt at high temperature.
5. Moisture resistance: The surface of the Teflon coating film is not stained with water and oil, and it is not easy to stain the solution during the production operation. If there is a small amount of dirt, it can be removed by simple wiping. Short downtime saves man-hours and improves work efficiency.
6. Abrasion resistance: Under high load, it has excellent abrasion resistance. Under certain load, it has the dual advantages of wear resistance and non-adhesion.
