Silicon carbide wear-resistant liner liner, can grouting molding can dry pressing molding, mohs hardness of 9.2 above, hardness is second only to diamond, has the high wear-resisting corrosion resistance impact resistance paste construction is convenient wait for a characteristic, can be made into arc plate, fan-shaped plate, perforated plate, plate, the impact block size etc, through the ceramic adhesive stick welding process, such as vortex chamber stitching line in hydrocyclone The inner wall of the conical pipe, the bend of the sink nozzle and the three-way diameter change pipe can bearthe impact wear of high concentration and large particle material fora long time, so as to achieve the effect of wear and corrosion resistance and reduce the production cost
