The porosity of hydrophilic ptfe membrane
In recent years, in order to better respond to the call of national policies and concepts to protect the environment, hydrophilic PTFE membrane As a new type of polymer environmentally friendly material, it has been of great help in meeting the requirements of industrial environmental protection and clean production.
Usually through two or more filtration methods of the same or decreasing pore size, collectively called sequence filtering. In the sequential filtration system, if a sterilizing grade filter is added before the final sterilizing filter, and the sterility between the two filters is ensured, and the microbial contamination level of the pre-filtration medium is controlled to be generally less than or equal to 10cfu/100ml, this kind of This situation is called a redundant filtering system.
The porosity of the hydrophilic PTFE membrane can reach 80%~90%, and it has undergone 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 it has a surface filtration mechanism. , easy to remove dust, with strong hydrophobicity and low surface energy, which can ensure the complete retention of impurities such as bacteria, while having a large flux. When used for gas filtration, it can achieve 100% interception of various phages, bacteria and particles above 0.02um.
It is a fluorine material film manufacturer integrating production, sales and customization. The company has advanced hydrophilic 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.
