By utilizing the production technology of our patent, the filtering plate consisting of two pieces of cavity-structures which is produced by mainly using corundum-based material. The process include raw-material classification, cleaning & selecting, mixing, high-accuracy molding through die stamping, stage-wise high-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 function is small; The cleaning of filtering plate is easy; The surface layer is of high strength and wear-resistant. The two pieces of cavity-structures are glued together using epoxy glue imported. The gluing is of high strength and is corrosion-resistant & wear-resistant.

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