Microporous Membrane Filter white color NYLON material φ47 φ50 for cosmetic gamma sterility

The overview is made of nitrocellulose and cellulose acetate. It is a porous membrane filter material with a relatively uniform pore size distribution of penetrating micropores. The porosity is as high as about 80%. The microporous membrane is made of a polymer chemical material, and the pore-forming additive is specially treated and applied to the support layer. In the application of membrane separation technology, microporous membrane is the most widely used membrane variety. It is simple and fast to use, and is widely used in many fields such as scientific research, food testing, chemical industry, nanotechnology, energy and environmental protection. The microporous membrane is hydrophilic, non-toxic and hygienic. It is a porous membrane filter material with a relatively uniform pore size distribution and a microporosity with a microporosity of up to 80 Å. It is mainly used for the filtration of aqueous solutions, so it is also called aqueous film. Second, the characteristics of the pore size is relatively uniform, high porosity, no media shedding, thin texture, low resistance, fast filtration rate, minimal adsorption. It is flammable and should be sealed, moisture-proof and fireproof. Third, the main purpose of filtering liquids and bacteria such as liquid medicine, gas, oil, beverages, alcohol, electronic instruments, etc., can also be used for the inspection of particles and bacteria.

Overview and characteristics: Polypropylene microporous membrane is made of polypropylene microfiber hot melt bonded together. It is a membrane material for deep filtration. It has the following characteristics: food grade isotactic polypropylene is used as raw material. , no additives in the whole process of production; stable physical and chemical properties, good compatibility; with a series of pore diameters, high porosity, large amount of dirt, recoil and high temperature disinfection; good pressure resistance
Accuracy: 0.1um, 0.22um, 0.45um, 0.65um-100um

Note: (1) The nominal accuracy is detected by bubbling pressure method, and the detection reagent is anhydrous ethanol. (2) The flow rate is the initial water pressure of 0.1 MPa, the film thickness is 0.18 mm-0.35 mm, and the water flow rate under the condition of raw water turbidity 3 NTU detection. (3) The above parameters can be adjusted according to the specific requirements of customers.
3, size: diameter (mm) 50, 60, 100, 150, 200, 300, 400, 500, 550, 600, 800, 1000, 1200, 200 × 200, 300 × 300, 400 × 400, 500 × 500 600×600

Parameter:

1. PP filter membrane is made of polymer material, non-toxic, and can be widely used in medicine, chemical, food, beverage and other fields.
2, PP filter membrane is excellent in chemical resistance, it can be resistant to acid, alkali and solvent, including polar solvents (except benzene xylene).
3, PP filter membrane temperature resistance, can be 121 ° C, 30 minutes hot pressing disinfection, working temperature below 100 ° C.
4, PP filter membrane strength, no deformation, no media shedding, no re-contamination. It can be used after infiltration with 70% ethanol for several minutes before use.
5, PP filter is a deep filter, the resistance is small, the flow rate is fast, in the case of low pressure difference, it can reach higher flow, long service life, especially suitable for differential filtration, high viscosity, filtration of many suspended materials, filtration time The longer the filter, the higher the filtering accuracy.
6, PP filter membrane is hydrophilic, especially for liquid filtration or gas filtration.
