The filter box of our company adopts a high-efficiency filter method that removes impurities, and the filter method and equipment size can be flexibly selected depending on the customer's production requirements. Compared with the two-channel or multi-channel filtration used in the past, the two-stage filtration equipment has higher filtration accuracy, which is conducive to alloying treatment, and at the same time avoids the heterophasic polymerization to grow into metastable coarse particles and then diffuse and decompose into particles with the fluid. In this way, depending on the pore size of the filter plate, the particles can be captured by the second-stage filter plate before the particles are decomposed. This structure solves the problems of aluminum foil pinholes and profile burrs, and reduces extrusion dark lines. This device has been verified by the Patent Office, applied for and passed a utility model patent.
