A ceramic surface polishing and repairing process

Abstract

The invention discloses a ceramic surface polishing repairing process which comprises the polishing process and the repairing process. In the polishing process, a carbon nano tube and micro-nano-level silicon nitride abrasive materials are matched to serve as functionality components of polishing liquid, the high-performance polishing treatment of workpieces is achieved under the abrasive wheel mechanical effect, the degree of finish is high, the nano-order carbon nano tube will permeate into cracks of the workpieces, and a certain repairing effect on the cracks is achieved; the polished workpieces are subject to polydopamine film wrapping treatment, polydopamine serves as a carrier, stem grafting of a metal-organic framework is carried out, then the workpieces are subject to heat treatment, and the ceramic workpieces with the surface adhering porous coal are obtained; and then a boron oxide glycol solution is used for repairing the surfaces of the workpieces, boron oxide becomes liquid under the condition that the temperature ranges from 600 DEG C to 650 DEG C and permeates into cracks of the porous coal framework and the interiors of the workpieces, then the temperature rises to 800 DEG C to 900 DEG C, crack healing is achieved, and therefore the repairing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of ceramic polishing, in particular to a ceramic surface polishing repair process. Background technique [0002] Due to defects such as deformation, unevenness, wavy edges, hidden cracks and other defects on the ceramic tile surface during the sintering process, the rough products after leaving the kiln need to go through processes such as edge grinding, scraping, rough grinding, polishing, and coating. The smoothness and flatness of the ceramic surface is a key process that affects the surface quality of ceramic tiles. The conventional method of polishing the surface of enamel ceramics is to use a high-speed rotating grinding wheel and a coolant to grind and polish the ceramic glaze under a certain pressure. The traditional polishing method mainly has poor flatness, poor luminosity, and improper vibration and grinding. Larger cracks are prone to occur on the glaze surface, resulting in high brittleness of ...

The conventional method of polishing the surface of enamel ceramics is to use a high-speed rotating grinding wheel and a coolant to grind and polish the ceramic glaze under a certain pressure. The traditional polishing method mainly has poor flatness, poor luminosity, and improper vibration and grinding. Larger cracks are prone to occur on the glaze surface, resulting in high brittleness of ceramics during use, and the surface glaze layer falling off, which seriously affects product performance
