Precision filter materials mainly include sintered filter tube, melt-blown fiber filter and honeycomb filter.
Sintering tube is formed by sintering powder materials, the filter tube materials are ceramics, glass sand, plastic and so on. Melt-blown fiber filter element is generally made of polypropylene as raw material, which is made by heating melting, injection, traction and receiving molding. PP filter element with polypropylene as raw material is more commonly used.
Honeycomb filter is made of textile fiber roving precision winding in the porous skeleton, polypropylene line around the honeycomb filter is commonly used.
