What Materials Are Used in UF Membrane?

  Ultrafiltration membrane is a kind of filtration technology between microfiltration and nanofiltration, and its membrane filament is made of various materials, mainly including the following:

1. PVC (polyvinyl chloride): the membrane filament made of this material has high strength, is not easy to break, has good hydrophilicity, and is relatively inexpensive. Due to the unique membrane manufacturing process and membrane filament post-treatment process, PVC membrane filament filtration accuracy, temperature resistance, corrosion resistance and other properties have been significantly improved. Therefore, PVC is one of the most common ultrafiltration membrane materials on the market.

2. PP (polypropylene): the membrane filament of this material has excellent mechanical properties and heat resistance, good chemical stability, and can withstand a variety of chemical media in addition to strong acids and alkalis. the pore size distribution of PP ultrafiltration membranes is narrow, with high filtration precision, suitable for the separation and concentration of macromolecular solutions, proteins, oils and other substances.

3. PS (polystyrene): the membrane filament of this material has good light transmittance, waterproof and moisture resistance, and is not easy to be deformed and aged. ultrafiltration membranes made of PS are suitable for filtering solutions containing pigments and dyes, such as pulp, dye wastewater and so on.

4. PE (polyethylene): the membrane filament of this material is soft, pressure-resistant, abrasion-resistant, acid- and alkali-resistant, and is suitable for all kinds of water treatment fields. ultrafiltration membranes made of PE are usually manufactured by meltblown process, which has better filtration performance and longer service life.

5. PTFE (polytetrafluoroethylene): the membrane filament made of this material has excellent resistance to high temperature, corrosion and aging, and can be used in harsh environments such as strong acids, alkalis and organic solvents etc. Ultrafiltration membranes made of PTFE are suitable for filtration of solutions containing macromolecules, such as proteins, enzymes, nucleic acids etc. Different ultrafiltration membranes have different characteristics.

Different ultrafiltration membrane materials have different characteristics and scope of application, according to the actual needs of the selection of suitable materials to meet a variety of water treatment needs.

  JX-purification has developed TIPS PVDF ultrafiltration membrane filament, the quality is the best, at present there are not many factories in China can do it, buy this kind of membrane filament will make your membrane quality better.

Advantages of TIPS ultrafiltration membrane：

  As a kind of filtration membrane, ultrafiltration membrane has the following advantages:

1. High filtration precision: the pore size of ultrafiltration membrane ranges from 1-100 nanometres, which can filter out most of the impurities such as tiny particles, suspended matter, bacteria and viruses, and achieve high-precision filtration effect.

2. good flux performance: ultrafiltration membrane has a high flux, which can ensure the filtration effect at the same time, reduce the filtration resistance, reduce filtration costs.

3. good chemical stability: ultrafiltration membrane has good corrosion resistance and chemical stability, which can adapt to various chemical environments and is not easy to be corroded or produce harmful substances.

4. good mechanical strength: ultrafiltration membrane has high mechanical strength, can withstand greater pressure and friction, not easy to break or deformation.

5. Long service life: the service life of ultrafiltration membrane is long, generally up to several months to several years, reducing the frequency and cost of membrane replacement.

6. environmental protection: ultrafiltration membrane can be reused, reducing the pollution of the environment and waste of resources.

7. Easy to clean and maintain: ultrafiltration membranes are easy to clean and maintain during use, and can be used to remove pollutants and restore their filtration performance through simple physical or chemical methods.

8. Wide application: ultrafiltration membrane can be applied in various fields, such as water treatment, biomedicine, food and beverage, environmental protection, etc. It has a wide range of application prospects.
