PTFE composite membrane can intercept dust
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, whether it is strong acid or alkali, such as sulfuric acid, hydrochloric acid, nitric acid, caustic soda or even aqua regia, or strong oxidants, such as potassium dichromate, Even potassium permanganate can’t move even a hair on it. 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, it has small and uniform pore size, surface filtration mechanism, easy dust removal, strong hydrophobicity, low surface energy, good non-adhesive ability, and effectively removes dust accumulated on the surface.
It is a fluorine material film manufacturer integrating production, sales and customization. The company has advanced polytetrafluoroethylene composite membrane production lines as well as composite production lines. The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
