The reason why PTFE is difficult to bond
First, its surface energy is relatively low, and the surface tension is very small. Therefore, when we bond, we cannot fully wet the PTPE on the surface, which will lead to difficult bonding, which is a cause of objective existence. If you want to change, you need to change the composition of PTFE so that you can solve this problem.
Second, the cleanliness of the surface is very large, so that it will ensure its chemical properties, then it will increase the difficulty of bonding. This is an important point, and it is considered to be controllable. In response to such a situation, we must also deal with it in a timely manner, first determine the cause and then solve the problem, so that we can slightly change the state, so as not to affect the work situation.
Various profiles and parts made of PTFE, such as bars, tubes, films, bearings, gaskets, valves, etc., are widely used in machinery, chemical, aerospace, electrical and electronics, defense industry, cutting-edge technology, medical and electrical insulation. And other fields.
PTFE has excellent performance
PTFE has many excellent functions. Such as a very low coefficient of friction, non-stick surface characteristics, a wide temperature range of -180 ° C ~ +260 ° C, excellent resistance to aging and chemical resistance. The PTFE raw material belt is made of 100% PTFE, which has a network of elongated fibers and a network of expanded structures. The PTFE raw material belt has the characteristics of good toughness, high longitudinal strength and easy deformation in the transverse direction. It is ideal for sealing on the packing and thread. However, it cannot be used in situations where high concentrations of oxygen or liquid oxygen are desired to come into contact. The Teflon tape is mainly used for packing and threaded seals. It is widely used in the sealing of pipe plugs and valve interfaces for strong oxidants, strong acids, alkalis, oxygen, gas, high temperature steam and various chemically aggressive media. The Teflon raw material belt is an auxiliary product commonly used in plumbing installations, used for pipe joints to enhance the tightness of pipe joints.
