The series is compounded and shaped from special bone, anchoring agent, binder and little rare-earth element corrosion resistance, after pore-foring sintering, we make it, that made up many porous silerring of distribution, domearch openning connected with each other, when the liquid passing, the suspended tance, colloid porous and big molecule organic matter are dammed on the surface of the product, it is corrosion resisting, and standing up to high temperature, not become deformed, easily to be watered, long working period and no harmful matter coming out. It can instead of such filter as cotton, textile, metal wire and asbestos cloth. It is widely used in the separation and filtration of liquid phase and gas phase in petrochemical, environmental protection, engineering, etc. Especially for getting off dust and waste water from stove, it is a kind of high effection and perfect filter.
