Three steps can be formed to produce pp melt blown filter element, the process is followed by high-temperature melting, jet stretching, accumulation molding, through this series of processes,pp spun filter element is shown in front of us.pp represents the raw material of melt-blown filter cartridge, that is, polypropylene raw material.
Polypropylene melt blown filter element can remove suspended matter in the liquid, impurities, microorganisms and other impurities that pollute the water source, it can effectively remove these impurities and its structural characteristics are inseparable, its clever structural design is the key to affect the filtration effect.
The structure design of Pp melt blown filter cartridge mainly adopts gradient density design and three-dimensional mesh structure. Gradient density is the key of progressive filtration, and its density gradually increases from outside to inside, which makes pp melt-blown filter element can retain pollutants and impurity particles of different precision in batches. Its three-dimensional mesh structure is the effect of jet stretching, which uses mechanical screening and adsorption to be more efficient and remove impurities faster and better.
The whole structure of this filter element is without any other adhesive, and it solely relies on its own hot melt to bond, ensuring that there will be no secondary pollution.
