The configuration requirements and ultrafiltration effect of PP strting wound filter cartridge making machine

PP string wound filter cartridge making machine in the production process of the structure for the outer layer of coarse fiber and fiber thin, for use in the process of loose its outer and inner diameter gradient gradually tight structure, when making use of the very unique gradient form can be solid residue effect deep filter, when making use of high interception rate, high porosity and large quantity, etc.

 

PP string wound filter cartridge making machine effectively using a kind of polymer extrusion nonwoven technology, this technology originated in the early 1950 s, started developing with super fine filtering effect of filtering material, research results published in 1954.The fusion technology of China originated from the late 1950s and early 1960s, and the equipment studied was intermittent.By the late 1960s and early 1970s, the number of China's intermittent melt-spraying equipment had reached more than 200

 

All the raw materials of thermoplastic (high temperature melting and low temperature curing) can be used in yarn filter core.Polypropylene is a slice of filter application most raw materials, in addition, melt-blown technology commonly used polymer sliced raw materials of polyester, polyamide, polyethylene, teflon, polystyrene, PBT, EMA, EVA, etc.
