Teflon RodThe raw material has the small and medium-sized interfacial tension of the solid raw material, does not adhere to all chemical substances, and also has the characteristics of high and low temperature resistance test, which makes it very common in the production and manufacture of non-stick pot for example.
Teflon RodThe key to the glue removal process includes two kinds:Teflon RodThe component or sheet is mounted on the substrate, and itsTeflon RodCoated or laminated glass composite type of lacquered cloth after heat shrinkable film and set on the plate.
With the continuous development trend of raw material application technology,Teflon RodThe three major defects of raw materials: cold flow, difficult welding welding, refractory process performance has been slowly get rid of, and then make it in electronic optics, electronic devices, medicine, petrochemical equipment, petroleum pipeline waterproof layer and other diverse industries more broad application prospects.
Teflon RodThe characteristics are stable, but care should also be taken to avoid high temperatures, which is very much to prevent the use of fire.Harmful gases are dissolved above 400°C. PTFE can be long-term application at 260 ℃. Because high-temperature cracking also causes toxic by-products such as fluorine and phosgene, it is necessary to pay attention to safety precautions and avoid PTFE touching fire.
Teflon RodIt is a high polymer of tetrafluoroethylene, a Milky White or gray chemical substance. It is made by converging with hydrochloric acid at high pressure.Teflon Rod, inAt 370 ° C., the obtained tetrafluoroethylene powder was molded and calcined, resulting in a tough, non-thermosetting plastic and non-porous structure epoxy resin.Teflon RodAlthough most are crystalline, there is no melting point.
Teflon RodThe plastic deformation increases with the increase of temperature, while the physical properties are greatly affected. And over highAt 327 ° C., it changed into a transparent liquid with no fluidity and no shape. At temperatures above 400°C,Teflon RodDissolves and releases harmful volatile chloride vapors. Its ultra-low temperature characteristics are also very good, the temperature is less-80 ℃ can still maintain its ductility.
BecauseTeflon RodThe construction is high density, so it has vacuum pump characteristics. Its occupancy rate is very low, and its vapor pressure and outgassing rate at indoor temperature are very low, which is better than vulcanized rubber and other plastics.
