High quality PP folded filter parameters explanation - with the sterilization method 【 3 m filter.

PP folded filter membrane as the core of the membrane folded filter, 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. Endotoxin & le; 0. 25 ev/ml in the American pharmacopoeia ( VSP) Standard.

discount structure of pp cotton filter 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. But PP folded filter in addition to the above advantages, also has a small job stress ( General should not exceed 0. 3 Mpa, such as more than pore pressure expansion phenomenon) , solid easy wear filter, special working temperature greater than 60 ℃, the recoil effect is not ideal, and so on.

hebei pp folded filter testing and sterilization operation method:

detection steam supply and pressure of compressed gas, set them on the required value, the pressure value should be set at 1. 5 bar between 2 bar.

open va and vb, purify the steam line until completely remove the condensate.

open valve c, d, until completely discharge condensate.

slowly open valve c, increasing the flow of steam, to wait for 3 to 4 minutes further heating PP folding water filter.

some close vent valve b, d, f, make continuous discharge steam containing water droplets.

the folded filter as double polypropylene material discount structure, its inner layer as ( PP, PTFE, PES a) in the three Alone, for the final filter layer, the outer with aperture of non-woven fabric for the coarse filter layer, have played an important role prefiltering, internal and external stent for polypropylene or stainless just material; So the filter is pre filter and filter together. Filter filtration precision of 0. 10 and 0. 22, 0. 45, 0. 65, 0. 8, 1, 3, 5, 8 kinds of pore size, can choose according to customer's request.
