Stable filter melt-blown filter how to do?

In the middle of the water filter, filter belong to one of relatively stable water filter filtration efficiency, what determines its filtering stability? Mainly from three aspects are analyzed.

a work, 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.

2, melt-blown cartridge filter with high efficiency.

the melt-blown cartridge is different from the traditional fabric filter material, fiber diameter is relatively small, generally for 5 - 25 micron;

the irregular net-like porous structure of three-dimensional space, small aperture, the average pore diameter less than 40 microns, the porosity is large, the average porosity of 75% or higher, reasonably adjust the filtering accuracy and filtering the production of polypropylene melt-blown cartridge series of products the indicators through additional measurement.

3, long using time, 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) 。

in the process of filtering, big aperture section to accommodate large 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.
