keyword description: polyether sulfone membrane folding filter

folding polyether sulfone membrane filter material: using pure polypropylene pleated filter material, material in compliance with GMP and FDA, ultrasonic and hot melt, do not use glue, has a wide range of chemical compatibility. Polyether sulfone membrane folding filter structure: the filter for the double polypropylene material discount structure, the inner layer of polypropylene film as the filter layer, the outer with aperture alone non-woven fabric for coarse filter layer, have played an important role prefiltering, internal and external stent for polypropylene materials; So the filter is pre filter and filter together. Filtering accuracy is 0. 10 and 0. 22, 0. 45, 0. 65, 0. 8, 1, 3, 5, 8 kinds of pore size, choose according to customer's request. Operating polyether sulfone membrane folded filter conditions: the maximum operating pressure difference at 20 ℃ 5 maximum operating differential pressure 4 bar at 60 ℃ bar80 maximum differential operation 2 ℃. 8 nar high-temperature sterilization temperature does not exceed 100 ℃ polyether sulfone membrane folding filter advantages: discount structure filter has big filter area, low starting pressure difference, fast speed, the filter volume is small, the cost is small. Due to pre filtering, and eventually filter is a unity, so the filter capacitors carrying capacity is bigger. Service life is longer than a single aperture of filter. Single pure polypropylene material, easy to determine the chemical compatibility. Disadvantages: because of the filter layer of paper folding, pressure generally should not exceed 0. 3 Mpa, such as more than pore pressure expansion phenomenon, solid wear filter, special working temperature greater than 60 ℃, recoil effect is not ideal. Model: double tong ping pressure type: outer diameter & Phi; 70 mm diameter & Phi; 28 mm length international general standards: 10, 20, 30, 40 inches folded filter membrane as the core of membrane, determine the membrane filter material, the polypropylene without weaving ( Network) After folding, points as a guide and support, insert the center pipe, into the shell, each part adopts hot melt welding technology without adhesive, sealing form a complete integrated filter, do not contain chemical pollutants, products to 100% integrity testing.
