Membrane is a material with selective separation function. Membrane technology has been widely used in medicine, chemical industry, food, electronics, water treatment and other fields. Among them, membrane separation and purification technology is widely used, and the key to membrane separation technology lies in the membrane preparation technology.
PTFE, also known as polytetrafluoroethylene, is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all Solvent, high temperature resistance, filter membrane products processed from PTFE have strong physical and chemical performance stability. ptfe hollow fiber membrane is made of ptfe material. The product has good performance.
The basic principle of hollow fiber membrane is to use asymmetric microporous structure and semi-permeable membrane medium at room temperature with corresponding pressure and flow rate according to both sides of the membrane. The pressure difference acts as a driving force, allowing solvents and small molecule substances to pass through, while large substances and particles such as proteins, water-soluble polymers, and small bacteria are blocked by the filter membrane, achieving the purpose of separation, classification, purification, and concentration. A new membrane separation technology .
The ptfe hollow fiber membrane produced has strong hydrophobicity, chemical resistance, water resistance and low wind resistance, and can be obtained Very high dust removal efficiency. For some small particles with a diameter of 0.1um-0.3um, the filtration level can reach H13-U16. In addition, the biaxially stretched film can undoubtedly achieve very low emissions in intercepting various types of dust generated during the production process of the company, and all of them comply with current environmental protection standards.
The ptfe hollow fiber membrane has a fibrillar microporous structure, a porosity of more than 88%, and a pore size range of 0.1μm-1μm. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation. This film can also be coated on various fabrics and substrates using special processes to become a new filter material. Interested parties can enter the store for consultation.
