Speaking of Teflon casing, I believe everyone has a certain understanding of it through the previous introduction. They should also know that it is also called in some places."Teflon Casing". So, we know today to introduce the performance advantages of Teflon casing what are the following to introduce and its application.
Teflon casing in use when its advantages are also very clear. For example, the physical and mechanical properties, the relative density of Teflon casing is relatively large, the water absorption rate is low, and there is no elastic toughness; this is also a more prominent side. Moreover, it also has a very small coefficient of friction and shows good lubricity. In this case, it is naturally used in different places.
The static friction coefficient of Teflon casing is less than the dynamic friction coefficient, and the friction coefficient is almost constant from ultra-low temperature to melting point. In the future, when you use it, you must first understand these things. In this way, you will not be fooled when choosing. Of course, its hardness is low and it is easy to be worn by other materials, which is also the place you should pay attention. Therefore, if a PTFE film is formed on the surface of the abrasive, the wear loss can be reduced to a certain extent.
Teflon casing is a non-polar material with excellent dielectric properties. What you see now is also its advantages. And when in use, when the crystallinity of Teflon casing is inBetween 50% and 80%, the dielectric strength is almost independent of crystallinity, so that its dielectric properties are not affected by frequency and temperature, nor by humidity and corrosive gases; and the volume resistivity and surface resistivity of Teflon casing are lower in all engineering plastics. The thermal stability of Teflon casing is very prominent in engineering plastics.
It can be used fromFrom 200 degrees Celsius to the melting point, its decomposition rate is very slow, the decomposition amount is very small, the decomposition amount is less than one millionth of a month, and its temperature here is 200 degrees Celsius, so it is naturally negligible under such circumstances. Moreover, it is still not brittle at -250 degrees Celsius. Of course, it can be used for a long time at -250~260 degrees Celsius under such circumstances. And its use is also very extensive. For example, it can be used in the production and manufacture of exhaust pipes, pipelines and compressed air pipelines to transport corrosive vapors. It has become a key anti-corrosion material in chemical plants, crude oil, textiles and other fields.
The content of the above article is to introduce some basic information about the characteristics of Teflon casing and its application. Today's knowledge points are here first. Hope to help you, if you still don't understand anything, please continue to pay attention to our website.
