By utilizing the production technology of our patent, thefiltering plate consisting of two pieces of cavity-structures whichis produced by mainly using corundum-based material. The processinclude raw-material classification, cleaning & selecting,mixing, high-accuracy molding through die stamping, stage-wisehigh-temperature roasting, repetitious painting of function layer,cleaning & choosing, finalizing gluing, performance testing,packing and placing in storehouse.

Repetitious roasting and layer-after-layer painting are adopted.Thus, the arrangement of pores (interior is big, exterior is small)is clear; The resistance at restoring of filtering plate's functionis small; The cleaning of filtering plate is easy; The surfacelayer is of high strength and wear-resistant. The two pieces ofcavity-structures are glued together using epoxy glue imported. Thegluing is of high strength and is corrosion-resistant &wear-resistant.

Filtering tube is made from Teflon or stainless steel. Teflon tubepossesses better ductility that provides better capability againsttemperature-difference and deformation. Stainless steel tubepossesses high strength but less capability against deformation.The customer can choose different kinds of filtering tube accordingto working conditions.
