Melt-blown filter filtration efficiency is very stable

one Melt-blown filter pressure loss is small, filtration efficiency and stability. Polypropylene melt-blown cartridge in fine chemical fiber layer and rough fiber forming double fiber structure, reasonable reduces the loss of pressure of work, maintain the relative stability of filtration efficiency. two Melt-blown cartridge filter with high efficiency. Because of melt-blown cartridge is different from the traditional fabric filter material, fiber diameter is relatively small, generally for 5 - 25 microns, the irregular net-like porous structure of three-dimensional space, small aperture, the average pore diameter is less than 40 microns, porosity is large, the average porosity of 75% or higher, reasonably adjust the filtering precision, I plant the production of polypropylene melt-blown filter series products the indicators through additional measurement. 3. Use time long, filtering the cost is low. Melt-blown filter pore diameter gradient distribution along diameter direction ( According to the requirements of different medium filter can not only from inside to outside became smaller, can also be from outside to inside gradually become smaller) 。 Part in the process of filtration, large aperture can accommodate larger particles, there is enough space to ensure filter will not be fast blockage, and provide good shape stiffness: small aperture section can jam tiny particles, guarantee the filtration precision, fast to avoid the high precision filter clogging and the shortcoming of short service life, reduced the filtration resistance, reduce the energy consumption and improve the service life of the filter.
