Description

technical field

[0001] The invention relates to a metal filter tube and a preparation method thereof, in particular to an asymmetric stainless steel filter membrane tube and a preparation method thereof. Background technique

[0002] As an important member of the porous material family, porous metal materials have been widely used in functional fields such as filtration, separation, and fluid distribution in the fields of petrochemical, energy, environmental protection, food, and pharmaceuticals due to their unique properties. It is an indispensable key material to achieve technological breakthroughs. Porous metal materials have good permeability, controllable pores and pore sizes, stable shape, high temperature resistance, regeneration, and machinability. They are functional materials that cannot be replaced by other porous materials in some special industrial fields.

[0003] With the rapid development of modern industry, the requirements for the performance of filter mat...
