Polypropylene melt blown filter element is made of polypropylene resin as a raw material to make fibers, which are wound and bonded by the fibers themselves. The structure of the filter element is a structure with thick outer fiber, thin inner fiber, loose outer layer, and tight inner layer. The unique gradient deep filtration has formed a three-dimensional filter residue effect, which has the characteristics of high porosity, high rejection, large dirt holding capacity, large flow, and low pressure drop.
PP melt blown filter element has dense and uniform pore size and high filtration efficiency. Because particles will bridge the pores of the PP meltblown filter element, particles smaller than the pores can also be blocked, and the filtration efficiency is above 98%. PP melt blown filter element has high cleanliness and no pollution to water quality. Resistant to acid, alkali and other chemical reagents and organic solvents. PP melt blown filter element is strong, when the filter inlet and outlet pressure difference is 0.4Mpa, the filter element will not deform.
Absolute filtration accuracy: theoretically, the absolute filtration accuracy is called absolute filtration accuracy for the filtration of 100% of the marked particle size. Generally speaking, the absolute accuracy actually refers to the accuracy that “tends to absolute”.
Nominal filtration accuracy: the common value of the initial filtration accuracy of the filter element. The filtering of nominal precision for the marked particle size is probabilistic filtering. Filtration accuracy: 1μm, 5μm,
