Surface filtration mechanism of ptfe base membrane
The ptfe base tape film is mainly made of suspended polytetrafluoroethylene resin by molding and sintering into a blank, and then turning and rolling. It is a new type of polymer material. Today we will take a look at what this material has to offer Outstanding.
PTFE base tape film is a polytetrafluoroethylene film that is biaxially stretched vertically and horizontally. It is a new material that is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all solvents.
It has a microporous structure with staggered fibers. The porosity can reach 80%~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, and the surface filters Mechanism, easy dust removal, strong hydrophobicity, low surface energy, good non-adhesive ability, and effectively remove dust accumulated on the surface.
Using the pore-forming characteristics of polytetrafluoroethylene plastic resin, the ptfe base tape film is made by biaxial stretching method.
The surface of the membrane can reach more than one billion micropores per square centimeter. The diameter of each micropore (0.1μm-0.5μm) is hundreds of times smaller than the diameter of water molecules (20μm-100μm) and smaller than the diameter of water vapor molecules (0.0003 μm-0.0004μm) is tens of thousands times larger, allowing water vapor to pass through, but water droplets cannot pass through. This microporous structure can be used to achieve excellent waterproof and breathable functions.
It is a fluorine material film manufacturer integrating production, sales and customization.
The company has advanced PTFE membrane production lines and 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.
