. The difference between Teflon and PVC
Teflon is called Polytetrafluoroetylene in English, referred to as Teflon, PTFE, F4, etc. Teflon high-performance special coating is a fluorine coating with PTFE as matrix resin. The English name is Teflon, which is usually called Teflon because of pronunciation.
Teflon Molecular Formula Picture
It is Teflon, Teflon, Teflon, Teflon, etc. (all transliterations of Teflon). Teflon (Teflon) coating is a unique high-performance coating, combining heat resistance, chemical inertness and excellent insulation stability and low friction, with other coatings can not compete with the comprehensive advantages, its application flexibility makes it can be used in almost all shapes and sizes of products.
The main component of PVC is polyvinyl chloride poly (hydrogen ethylene), bright color, corrosion resistance, strong and durable, due to the increase in the manufacturing process of plasticizers, anti-aging agents and other toxic auxiliary materials to enhance its heat resistance, toughness, ductility, etc., so its products generally do not store food and medicine. It is a kind of synthetic material which is popular and widely used in the world today. Its global usage ranks second among all kinds of synthetic materials. PVC materials are widely used and are mainly used to make: Pruvin pvc cards; Pvc OEM; Pvc iron wire; Pvc curtain; Pvc plastic coated welding net; Pvc foam board, pvc ceiling, pvc water pipe, pvc skirting line, threading pipe, cable insulation, plastic doors and windows, plastic bags, etc. PVC products can be seen everywhere in our daily life. PVC is used to make a variety of imitation leather, used in luggage, sports products, such as basketball, football and football. It can also be used to make belts for uniforms and special protective equipment. PVC material is widely used, and has good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics.
2. Teflon wire refers to the outer skin, and the wire core in the middle is all metal wires.
Teflon line has high temperature resistance, up to 220 degrees, PVC line is generally 90-110 degrees.
3. Teflon wire because of the high molding temperature of the wire skin, so the surface of the metal wire is high temperature tin coating, so its welding temperature requirements than conventional PVC wire about 30 degrees higher.
4. The tin plating layer is high temperature tin, and the difficulty of plating metal tin is relatively large, and the coating is relatively thin. Therefore, in the welding process, because the tin layer is high temperature tin and the thickness is relatively thin, it is best to use flux to improve the welding effect.
5. Automotive temperature sensor due to the technical requirements of high temperature and oil resistance, Teflon line is the best choice.
6. The recommended soldering process is: soldering iron soldering 350-400 degrees/time is less than seconds solder paste flux.
