As we all know, uf membrane use is a whole screening process related to the diameter and size of the membrane. The filter paper material is very important in the work of uf membrane use, and different materials show different characteristics. Such as water absorption and pile formation; the filter paper material comes from stability and cost, which are the index characteristics of whether the filter material is suitable for your needs.

At present, there are four main types of uf membrane module in the sales market: polysulfone (PS), polyacrylonitrile (PAN), polyvinylidene fluoride (PVDF), polyvinyl chloride (PVC) and inorganic materials. In-depth analysis as follows:

1. Polysulfone (PS), a film made of this material, is easy to form, has good mechanical strength, high temperature resistance, and good solvent resistance. It is currently a widely used material.

2. Polyacrylonitrile (PAN) is similar to polysulfone, with good mechanical equipment and organic chemical properties. The nitrile group of PAN is a genetic gene with strong optical rotation, but PAN is not very hydrophilic. Generally, vinyl acetate or vinyl acetate is introduced to improve the flexibility and water absorption of the chain, thereby changing its process performance.
3. Polyvinylidene fluoride (PVDF). The uf membrane module of this material has excellent mechanical strength, heat resistance and solvent adhesion. It can be used in strong alkalis, strong acids and various organic solutions, but the cost is high.
4. Polyvinyl chloride (PVC), the uf membrane module produced by this material has good mechanical strength and excellent organic chemical adhesion properties, the material source is generally stable, and the cost is moderate, and a good ro uf membrane can be produced.

Generally speaking, this is a new type of uf membrane module material developed and designed in recent years. At present, China is still in the laboratory research stage and has not yet been commercialized. The ro uf membrane of this material has the characteristics of heat resistance, good resistance to organic solutions, resistance to embrittlement, strong renewable resources, and suitable separation.
