Manufacturing method of PP melt filter core equipment.

- May 21, 2018-

PP melt blown filter cartridge making machine is a non-toxic and tasteless polypropylene particle, which is made by heating, spraying, drawing and accepting the forming of tubular filter. If the material is mainly polypropylene. It can be called a PP melt filter element. It is not only used in water purification, but also has excellent chemical compatibility. It is suitable for filtration of strong acid, strong alkali and organic solvent. The structure of the PP melt filter core is the outer fiber thick, the inner layer fiber is thin, the outer layer is loose, and the inner layer is close to the gradual taper structure. The unique gradient deep filtration has formed the effect of solid filter residue, which has the characteristics of high porosity, high retention rate, large amount of pollution, large flow and low pressure drop.

PP melt-blown filter equipment manufacturing methods melt-blown technology is a kind of polymer extrusion nonwoven technology, originated in the early 1950 s, the U.S. navy lab to test for collection of radioactive particles, started developing a super fine filtering effect of filtering material, research results published in 1954. In China, the technology of melt-spraying originated from the late 1950s and early 1960s, and the equipment studied was intermittent. By the late 1960s and early 1970s, there were more than 200 stations in China. The continuous production line was introduced from the United States and Germany in about 92-94. So far, it is estimated that there are still more than 300 intermittent fusion devices running around the country.

Manufacturing method of PP melt filter core equipment.

(1) filtration efficiency and filtration precision, the filter core pore diameter is uniform, and the filtration efficiency is more than 99%.

(2) the filtering less resistance, large flow, large amount of sludge, long service life, this product in the production process of fiber diameter and clearance is adjustable, outer filter pore lining small to big, increased traffic and carrying capacity, filter is not easy to block, prolong service life.

(3) high purity, no pollution to water quality, acid and alkali resistance and organic solvents, corrosion.

(4) strength, import and export filter pressure difference is greater than 0.4 Mpa when the filter will not deformation, the temperature over 90 ℃, the filter efficiency will not decrease.

(5) this product is highly hydrophilic to polypropylene and can absorb up to ten times heavier water, so it can be used for oil and water separation.
