The English abbreviation of polytetrafluoroethylene is ptfe, also called Teflon. This material is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all solvents and is resistant to high temperatures. Therefore, people often combine ptfe with other materials to obtain polytetrafluoroethylene. Composite membrane.
Polytetrafluoroethylene is particularly resistant to corrosion. No matter it is strong acid or alkali, such as sulfuric acid, hydrochloric acid, nitric acid, caustic soda or even aqua regia, or strong oxidant, such as potassium dichromate or potassium permanganate, it cannot touch even a hair. . It can be said that its chemical stability exceeds that of glass, ceramics, stainless steel, and even gold and platinum. We know that even gold and platinum will dissolve in aqua regia. However, polytetrafluoroethylene remains the same after being boiled in boiling aqua regia for dozens of hours.
The polytetrafluoroethylene composite membrane has a microporous structure with staggered fibers and a porosity of up to 80% to 90%. After high-temperature heat setting treatment, the microporous structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform, the surface filtration mechanism makes it easy to remove dust, it is highly hydrophobic, has low surface energy, and has good non-adhesive ability, effectively removing dust accumulated on the surface.
