Production method and production line of whole-body large-particle stone-like ceramic thick plate

Abstract

The invention relates to the technical field of ceramic thick plates, and concretely relates to a production method and a production line of a whole-body large-particle stone-like ceramic thick plate.The production method of the whole-body large-particle stone-like ceramic thick plate comprises the processes of burdening, ball milling, granulating, forming, glazing, firing and the like. Blank rawmaterials of the large-particle stone-like ceramic thick plate and large-particle powder which is granulated and formed after extrusion have a high combination degree, and are not prone to cracking in the compression molding process and the sintering process, so the blank raw materials and the powder are suitable for manufacturing the large-thickness cylinder ceramic thick plate. Results of detection show that the thick plate has better hardness, antifouling property and corrosion resistance than natural stones; and the production line of the whole-body large-particle stone-like ceramic thickplate, provided by the inventor, has the advantages of high overall production efficiency, and effective reduction of the number of particle cracks, so the production quality and the customer experience effect are guaranteed.

Description

technical field [0001] The invention relates to the technical field of ceramic thick plates, in particular to a preparation method and a production line of whole-body large-grain imitation stone ceramic thick plates. Background technique [0002] Existing imitation stone ceramic tile usually carries out method decoration pattern such as ink-jet printing after applying primer once on the body surface, then applies transparent glaze once again, burnishes and polishes again. This type of product has rich patterns and bright colors, but only one surface of the tile is glazed with marble texture, and the tile after cutting is a monochromatic body, and its color is far from the texture of the marble surface. The beauty is not as good as natural marble. [0003] In order to solve the above problems, ceramic tile manufacturers add large particle powder to the green body. For example, the invention patent application with application number 201810537701.7 discloses a whole body anti...

AI Technical Summary

Problems solved by technology

[0004] The emergence of large-grained porcelain tiles can imitate natural stone vividly by using the size ratio and color matching of large particles. Cracking problem, the reasons for particle cracking are as follows: First, the particle size difference between the large particle powder and the green body powder is large. When the roller is pressed, there is a lumpy powder group between the two roller gears. , the residual powder group is repeatedly pressed when the roller faces the roller to form a high density and a very hard surface, which is different from the lumps caused by other powder groups, which will lead to particle cracking in production; the second is the size of the existing particles Insufficient strength leads to the crushing of large particles during the molding process, resulting in the appearance of cracked particles; in addition, in order to avoid easy cracking of the green body, the thickness of the green body is generally controlled at 9-15mm when making large-grain imitation tiles In order to ensure the successful yield, it is well known that the use of stone is often used for outdoor pavement and wall laying, and the thickness of the stone used will not be less than 20mm, so the existing imitation stone tiles can only be used indoors For decorative use, it cannot completely replace stone in use
