100Pcs PP Polypropylene Microporous Filter Membrane，Resistant to Organic Acid & Alkali Solution Filter Paper Dia.150/200/300/400/500 mm Optional (Dia. 500mm, Aperture 0.45μm)

🔔️🔔️Application fields 🔔️PP filter membranes are widely used in the fields of medicine, chemical industry, food, beverages, and electronics. 🔔️PP filter membranes have good strength, will not deform, do not have medium leakage, and will not cause re-contamination. 🔔️PP filter membranes have low resistance and fast flow rate. They can achieve a high flow rate even under low pressure difference, have a long service life, and are particularly suitable for filtering high-viscosity and items with a large amount of suspended matter. The longer the filtration time, the higher the filtration accuracy. 🔔️PP filter membranes are generally used for liquid filtration, but they can also be used for gas filtration. 🔔️🔔️Usage method of PP polypropylene filter membrane 🔔️For PP filter membranes, before use, they can be soaked in absolute ethanol for 1 hour. This can enhance their hydrophilicity and can also be used as a cleaning method. However, if you directly open and use it without following these steps, it is still possible, and generally, there will be no significant impact. The smooth side of the PP filter membrane is the front side, facing the liquid surface. Then, put the filter membrane into the corresponding filter device, check if it is sealed properly, and then perform the pressure (positive pressure/negative pressure) filtration operation. When the pressure gauge rises rapidly or the liquid output slows down rapidly, it is recommended to stop working immediately and replace the filter membrane.

• 🔔️Product Name: PP Polypropylene Microporous Filter Membrane
• 🔔️The PP polypropylene microporous filter membrane is a filtration material formed by thermally bonding ultra-fine polypropylene fibers together.
• 🔔️The product is made from food-grade polypropylene as the raw material. Throughout the production process, no additives are used. It features stable physical and chemical properties, high porosity, large pollutant-capturing capacity, and excellent pressure resistance.
• 🔔️Working tolerance temperature: ≦ 80°C
• 🔔️The PP filter membrane is slightly neutral and has poor hydrophilicity. It needs to be pressurized to become hydrophilic. If it still fails to become hydrophilic after pressurization, it is recommended to soak it in 75% or more ethanol before use. If your solution contains organic solvents, generally no such operation is required as most organic solvents can make the PP filter membrane become hydrophilic.
