Improvement method of ptfe

As we all know, polytetrafluoroethylene is widely used in various fields of national economy due to its superior comprehensive performance. However, polytetrafluoroethylene has a big shortcoming -- its surface is very smooth and it is difficult to bond with other materials, which causes great limitation to its application range. In order to make the application of ptfe more extensive and unrestricted, there are already commercial grade ptfe surface treatment agents, also known as sodium treatment agents, which can be used for ptfe pipe, film, plate, filling ptfe and other products surface treatment.
The purpose of the natrification treatment agent is to improve the adhesion performance, and it is used to treat plastics, fillers, pigments, adhesion carriers and other surface materials. Ptfe sodium primer is to improve the adhesion performance of ptfe and expand the application scope of ptfe. The surface of ptfe treated with ptfe sodium primer is hydrophilic and can be bonded with general glue.
The surface of the treated polytetrafluoroethylene is not resistant to ultraviolet light irradiation, in the strong ultraviolet light long-term irradiation, will lose the treatment effect. Therefore, after the treatment of polytetrafluoroethylene if not timely glue, should avoid light preservation.
In the application of ptfe is more and more extensive at the same time, the requirements of ptfe are also increasing. For many years, the surface treatment methods of ptfe have been studied in order to improve the adhesive properties of ptfe. There are many treatment methods, natrification is only one of them, is also one of the most widely used, other methods, such as plasma treatment, electrolytic reduction, high temperature melting treatment, radiation grafting treatment, metal evaporation and chemical filler method.
