A detection method for glaze shrinkage defects of sanitary ceramic products

Abstract

A method for detecting glaze shrinkage defects of sanitary ceramic products is disclosed. The detection method for glaze shrinkage defects of sanitary ceramic products compares the change of the distance between the two ends of the glazed fan-shaped ring body before and after sintering with the value of the unglazed fan-shaped ring body before and after sintering. The distance between the two ends changes to evaluate the effect of glazing on the sintering shrinkage of the green body. The glaze shrinkage defect detection method of sanitary ceramic products can solve the problem of evaluating the influence of glazing on the sintering shrinkage of the ceramic body in the production process of the ceramic body. In the process, the result of deformation caused by the difference between the deformation stress of the glaze layer and the deformation stress of the body itself is used to match the effect of glazing on the sintering shrinkage of the body to a greater extent in actual production, so as to determine the glaze formula and performance and the body. The matching of the reaction of the body in the firing and heating stage, and the function of detecting the defect risk of the glaze and avoiding the risk in the glaze performance design and production stage.

Description

A method for detecting glaze shrinkage defects of sanitary ceramic products technical field The present invention relates to the technical field of ceramic sintering glaze shrinkage defect detection, be specifically related to a kind of sanitary ceramics product Method for detecting glaze shrinkage defects. Background technique [0002] The sanitary ceramics industry has been developed in China for more than 40 years, and the domestic quality control methods for ceramic production are becoming more and more perfect. Defect prevention and control measures for various finished products are also developing continuously. Regular peeling off and the phenomenon that the surface of the ceramic body is exposed) There is no independent single detection method for the evaluation of defects. The current commonly used detection methods are generally through the double-sided glazed right-angle sample bricks used to detect the pore bubbles on the glazed surface. Whether there is s...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a method for detecting glaze shrinkage defects of sanitary ceramic products, which can solve the problem of the production process of ceramic bodies by using the detection method for glaze shrinkage defects of sanitary ceramic products. In order to evaluate the effect of glazing on the sintering shrinkage of the green body, this method uses the fan-shaped ring green body to faithfully record the difference between the deformation stress of the glaze layer and the green body itself during the firing process. Deformation results, in order to match the effect of glazing on the sintering shrinkage of the green body to a greater extent in actual production, so as to determine the matching of the glaze formula and performance with the reaction of the green body during the firing and heating stage, and realize the performance design of the glaze. and the function of detecting the defect risk of the glaze in the production stage and avoiding the risk
