PP melt blown filter cartridge production machine production process analysis

- Aug 31, 2018-

PP melt blown filter cartridge production machine widely used in the market are generally manufactured by a fully automatic PP melt blown filter cartridge production machine. The structure of the PP meltblown filter element is that the outer layer fiber is thick, the inner layer fiber is fine, the outer layer is loose, and the inner layer is tightly tapered to gradually tighten the structure. It is because of this special structure that it has a good filtering effect.

 

The melt-blown production process is one of the polymer extrusion non-woven processes. With the development of technology, the PP melt-blown filter production machine has gradually changed from intermittent operation to continuous production operation. In theory, all thermoplastic (high-temperature melting, low-temperature curing) polymer chipstock materials can be used in the production process of melt-blown filter elements. Polypropylene is one of the most used slicing materials in the melt-blown process. In addition, the polymer slicing materials commonly used in the melt-blown process are polyester, polyamide, polyethylene, polytetrafluoroethylene, polystyrene, PBT, EMA. , EVA, etc.

 

Usually, the PP melt blown filter cartridge production machine is a tubular filter made of polypropylene material, which is heated, melt blown, spun, drawn and received. If the material is based on polypropylene, it can be a PP meltblown filter. The structural characteristics of the PP meltblown filter produced are that the fiber fineness is relatively small, usually less than 10 microns, and most of the fiber fineness is between 1 and 4 microns.
