Method and inhibitor capable of inhibiting foaming of ceramic tile polishing waste in high-temperature sintering

Abstract

The invention discloses a method and an inhibitor capable of inhibiting foaming of ceramic tile polishing waste in high-temperature sintering. The inhibitor refers to at least one of quartz and aluminum hydroxide and contains at least one of wollastonite and borax. The method includes: mixing, by mass, 10-20% of the inhibitor, 10-20% of the ceramic tile polishing waste and 60-70% of common ceramic tile blank materials; moulding the mixture to obtain blanks; finally performing high-temperature sintering to obtain smooth and compact ceramic products. The method and the inhibitor have advantages that by adoption of quartz and aluminum hydroxide as the inhibitor, high inhibition efficiency, easiness in control and wide application range are realized; the problem of high technique implementation and control difficulty in ceramic tile polishing waste based ceramic tile production is solved; efficient recycling of the ceramic tile polishing waste is realized, structural and appearance quality of ceramic tiles can be improved, production material cost is reduced, and high utilization rate and reduction of emission pollution of waste residues and materials are realized; technical simplicity in preparation, easiness in control, wide applicability and convenience in implementation and popularization are realized.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to an inhibitor and a method capable of suppressing foaming of ceramic brick polishing waste residue during high-temperature sintering. Background technique [0002] Ceramic tile polishing slag is mainly produced during the grinding and polishing process of ceramic tiles, and its components are mainly silicon carbide, magnesium oxide, magnesium chloride and brick chips in the grinding block; according to whether it contacts the polishing grinding block, the polishing slag is divided into Polishing waste that has been in contact with the polishing block and polishing waste that has not been in contact with the polishing block. [0003] In the prior art, the polishing slag that has not been in contact with the polishing block is added to the conventional powder in a certain proportion to produce porcelain polished tiles; and the most difficult to deal with is the polish...

The patent of Guangdong Hongtao Ceramics Co., Ltd. (publication number CN102617123) "Formulation and method for manufacturing ceramic tile body and glazed tile by using polishing waste residue" discloses a formula and method for manufacturing ceramic tile body and glazed tile by using polishing waste residue. Heat preservation, prolonging the firing time, increasing the oxidizing atmosphere and other means to ensure the gas discharge of ceramic polishing slag, overcome the shortcomings of the product foaming due to the excessive gas discharge of ceramic polishing slag at high temperature, but there are still complex processes, Not only need to adjust the formula, but also need to change the original firing system and firing atmosphere of the kiln, the difficulty of process implementation and control, low universality, and the disadvantages that are not easy to promote
