Method of manufacturing ceramic sheet with concave-convex mould effect on plane green body

Abstract

The invention relates to a method of manufacturing a ceramic sheet with concave-convex mould effect on a plane green body. The method includes: (1) pressing a plane green body, and performing drying at 140-170DEG C for 70-120min; (2) spraying engraving ink on the green body surface to obtain the pattern of the engraving ink as the mould pattern, and controlling the temperature of the green body surface at 40-50Deg C; (3) applying ground glaze, performing pattern decoration and applying cover glaze respectively on the green body sprayed with the engraving ink to obtain a semi-finished product;(4) conducting high temperature firing the semi-finished product at 1163-1187DEG C for 78-95min to obtain a ceramic sheet with concave-convex mould effect; and (5) conducting glaze polishing and edging processes on the fired sheet green brick so as to obtain a finished product.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a method for manufacturing a ceramic thin plate with a concave-convex mold effect on a planar green body. Background technique [0002] There are many types of ceramic floor tiles, among which products designed and produced according to the surface effects of stone and wood are more popular in the market. These ceramic floor tiles imitating stone and wood effects, combined with stone and wood moulds, can almost make the real ones look like real ones. At the moment when the country is emphasizing energy saving and emission reduction, with the advancement of technology and the improvement of consumer awareness, ceramic thin plates are 1 / 3 thinner than traditional ceramic tiles and have less consumables. Thinning development of the ceramic industry. Similarly, with the development of science and technology, the decorative effect of ceramic thin plates and ceramic floor ...

AI Technical Summary

Problems solved by technology

[0004] But above-mentioned production method is the method that building pottery production enterprise has used for many years, there are many deficiencies

One is that the mold needs to be replaced frequently, which increases the work intensity of the employees and the difficulty of production; the second is that the mold body will crack, and the mold with the greater the unevenness changes is more obvious; the third is that the texture of the mold body and the surface pattern sometimes deviates , so that the product grade has dropped significantly; Fourth, with the loss of molds in the production process, there is a big difference between the products produced by using the mold for the first time and the products produced after the mold has been used for a period of time, and the stability of the product mold effect cannot be guaranteed.
