PAN ultrafiltration membrane UF-4040-4 inch PAN ultrafiltration membraneis determined by comparing the pore size of ultrafiltration membrane with the diameter of harmful substances. When the diameter of harmful substances is larger than the pore size of ultrafiltration membrane, they can be retained by ultrafiltration membrane. With the continuous maturity of membrane technology, it has become the mainstream technology for purifying drinking water in the world, and has also been widely used in the fields of beverage, biology, food, medicine, etc.

PAN ultrafiltration membrane UF-4040-4 inch PAN ultrafiltration membranefeatures:

Compared with PVC ultrafiltration membrane, it is more brittle, the membrane filament is easy to break, the quality is poor; the acid and alkali corrosion resistance is poor, and the service life is short; the main composition is polyacrylonitrile, which is not a food-grade material, and may cause secondary pollution. The lack of these advantages results in high PAN yield and low cost.

Second, the compression resistance, flexibility is better, will not be subject to external force and easy to break, therefore, ultrafiltration membrane wire is not easy to break, the quality is better than PAN ultrafiltration membrane; corrosion resistance is good, so the service life is longer than PAN; for food grade materials PVC, will not cause secondary pollution; not easy to absorb water, easier to clean. However, PVC so many advantages mean that its raw materials are more expensive, manufacturing processing is more complex, and the cost is higher than PAN.
