First, the working principle
Precision filter, also known as security filter. The shell is made of high quality stainless steel, the filter is made of filter material (polypropylene fiber meltblown or wire wound honeycomb), under the action of pressure, so that the liquid through the filter, filter residue on the filter, the filtrate through the filter Outflow, can effectively remove impurities in water, sediment and suspended solids, bacteria, so as to achieve the purpose of filtration.
Precision filter is the use of forming the filter, under the action of pressure, so that the liquid through the filter, filter residue to stay in the filter wall, the filtrate through the filter out, so as to achieve the purpose of filtration.
Molding filter are: filter cloth, filter, filter, sintered filter, wire wound filter, melt blown filter, microporous filter and multi-functional filter.
The filter pore size is not the same due to the different filter media. Precision filtration is between the sand filter (coarse filter) and ultrafiltration between a filter, filter pore size is generally 0.01-120um range. The same type of filter, according to the size is divided into different specifications.
Wire wound filter (also known as honeycomb filter) there are two: one is polypropylene fiber - polypropylene skeleton filter, the maximum temperature of 60 ℃; the other is cotton fiber cotton - stainless steel skeleton filter, the maximum temperature of 120 ℃.
Melt-blown filter is made of polypropylene as raw material, the use of melt-blown process to form the filter, the maximum operating temperature of 60 ℃.
Precise filtration removes suspended solids from water, certain colloidal substances and fine particles.
Second, the performance characteristics
1, high filtration precision, uniform filter aperture.
2, filter resistance is small, flux, interception ability, long service life.
3, the filter material cleanliness, the filter media without pollution.
4, acid, alkali and other chemical solvents.
5, strength, high temperature, the filter is not easy to deformation.
6, low prices, low operating costs, easy to clean, filter can be replaced.
