Surface modification of PTFE board

- Jun 11, 2020-

Due to the extremely low surface activity and non-stickiness of PTFE plates, it is necessary to modify the surface of PTFE plates with other composite materials. PTFE plates are widely used as high and low temperature resistant, corrosion resistant materials, insulation materials, anti-sticking coatings, etc. in the industries of atomic energy, aerospace, electronics, electrical, chemical, machinery, instrumentation, instrumentation, construction, textile, food and other industries. So, what is the surface modification of PTFE board? The PTFE plates were treated with low-temperature plasma of some inert gas, resulting in the breaking of carbon-fluorine bonds or carbon bonds, generating a large number of free radicals, thereby increasing the surface free energy of the PTFE plates and improving their wettability and Adhesion. PTFE plates are widely used as high and low temperature resistant, corrosion resistant materials, insulation materials, anti-sticking coatings, etc. in the industries of atomic energy, aerospace, electronics, electrical, chemical, machinery, instrumentation, instrumentation, construction, textile, food and other industries. Immerse the tetrafluoride plate in the potassium acetate melt and process it at an appropriate temperature to form an active activation layer. Adding heat treatment to the mixture of sodium hydroxide and melamine can improve the surface activity of the PTFE board. After a certain intensity and time of corona treatment, PTFE plates can be formed. After chemical corrosion modification, the PTFE board can be treated with certain chemical reagents to improve its surface activity. These chemical reagents can be sodium metal amide solution, sodium naphthalene tetrahydrofuran solution, alkali metal amalgam, pentaalkyl iron solution, etc.
