Application of PP Cotton Melt Blown Filter Element in Core Filter

January 25,2022

PP filter element is a continuous filter element formed by the high-temperature melting of polypropylene material and spraying fiber into a special filter element forming machine. Different production technologies can be used to control different filtration accuracy, and can also form a surface filter element with consistent internal and external accuracy or a deep filter element with tight internal and thin external accuracy. The filter element itself does not use any chemical adhesive, which is more in line with the high-quality requirements of hygiene and safety.

Features of PP filter element:

  1. It can effectively remove various particle impurities in the filtered liquid;
  2. Multi-layer depth structure, large pollution capacity and long service life;
  3. Large filtration flow and small differential pressure;
  4. Multiple precision options are available to meet different needs;
  5. It does not contain any chemical adhesive, which is more hygienic and safe;
  6. Resistant to acid, alkali, organic solution and oil, with good chemical stability;
  7. Low cost and easy replacement. Usage: suitable for liquid filtration.
  8. The service life is 3-6 months, and the water treatment capacity is about 6-10 tons.
  9. It integrates surface, deep, coarse and fine filtration; It has the characteristics of large flow, corrosion resistance, high pressure resistance and low cost. It is used to block large particles such as rust, sediment and insect eggs in water.


Melt blown filter:

It is a tubular filter element made of non-toxic and tasteless polypropylene particles through heating, melting, wire spraying, traction and forming If the raw material is mainly polypropylene It can be called PP solution spray filter element It is not only used in large quantities in water purification It also has excellent chemical compatibility and is suitable for the filtration of strong acids, bases and organic solvents. The utility model has the advantages of strong pollution holding capacity, long service life and low cost Filtration accuracy: 1um, 3um, 5um, 10um, 20um, 30um, 60um


Applicable pH value: 1-13

Maximum differential pressure: positive 0.4MPa.

Operating temperature: < 70 ° C at 0.25MPa.

Sterilization: withstand 126 ° C and online steam sterilization for 30 minutes.

Endotoxin: the content of endotoxin in the water extract of the filter column is less than 0.5eu/ml after LAL test


Application of filter element filter in various industries


Water treatment filter element type filters generally include PP melt blown filter element, folding filter element and wire wound filter element. The accuracy is 0.1 micron, 0.22 micron, 1 micron, 3 micron, 5 micron, 10 micron, 20 micron, 50 micron, 100 micron, etc. precision filter element, security filter element and microporous membrane filter element are commonly used.


  1. The wire wound filter element is a kind of deep filter element, which is used for filtration with low viscosity and low impurity quality. It is made of textile fiber thread (polypropylene thread, degreased cotton thread, etc.) accurately wound on the porous skeleton (polypropylene or stainless steel) according to specific process. It has a honeycomb structure with sparse outside and dense inside, which can effectively remove suspended solids, particles, rust and other sundries in the fluid; it has very excellent filtration characteristics.


  1. PP cotton melt blown filter element: it is a kind of filter material made of non-toxic and tasteless polypropylene through heating, melting, spraying, traction and receiving. PP filter element has a deep filtration structure with uniform pore size, sparse outside and dense inside, and has the excellent characteristics of high filtration efficiency and acid and alkali resistance. It can effectively remove suspended solids, particles, rust and other impurities in the liquid.


  1. Folding filter element: excellent chemical compatibility, suitable for filtering strong acids, alkalis and organic solvents. The filter membrane is folding deep filtration. The membrane has large filtration area, low pressure difference, strong pollution holding capacity, long service life and wide filtration accuracy.


Application fields of precision filter element:

Pharmaceutical industry: pre-filtration of various antibiotics and other pharmaceutical solutions

Food and beverage industry: filtration of alcohol, mineral water and drinking water

Petroleum Industry: oilfield water injection filtration

Electronic industry: high purity water pre-filtration

Chemical industry: filtration of various organic solvents, acids and lyes
