how PP filters filter, filtering principle is what?

small butterfly yesterday received a customer consultation, he mentioned a problem, he asked & other; How PP filters filter & throughout; Released, so the small butterfly answers the question here, hope I can make more customers first contact PP filter can better understand it.

the first PP filters

the definition of PP filter also called PP melt-blown filter, filter by food-grade polypropylene superfine fiber after heating molten, injection, traction, receiving shape and made of. Fiber in random space form three-dimensional microporous structure, diameter d holes along the filtrate flow gradient distribution of integrating surface, deep, precision filter, can intercept different particle size of impurities. Below is the chart;

through the picture you can see, the guangzhou source filter production of PP filter is composed of three layer filter layer;

the first layer of loose layer, and the outermost layers of the filter, it is 30 micron filtration precision is

the second compaction layer, is also a filter layer, its filtering precision is 10 microns

the third layer precision, also is the core of layer, its filtering precision is

5 microns can know from this, it is by the filter in the outgoing, like a funnel, layers of filtration, this kind of structure not only ensure the filter filtering effect, and can increase its carrying amount, prolong its service life.

summarizes the PP filter using external pressure type filter is a principle, so need to put the filter when using a seal, a mouth, water enters the filter, through the pressure of tap water, the water from the surface of the filter pressing, the sediment in the water, particles, suspended solids, colloid, impurity substances such as intercept in the surface of the filter, clean water from the center of the filter through the filter outlet hole, into the pipe, this is the principle of filter.

through the sharing of small butterfly, if you to understand more about the PP filter, if you have more related questions of PP filters, welcome to inquire! Guangzhou filter source serve you wholeheartedly!
