Process for producing full polished glazed tiles

Abstract

The invention discloses a process for producing full polished glazed tiles. The process comprises the following steps: (1) selecting mineral raw materials, burdening, and carrying out ball milling soas to obtain slurry; (2) performing spray drying on the slurry so as to obtain powder, measuring and controlling the moisture of the powder to be 6.8-7.4%, wherein the grain composition is as follows:less than 1% of 20-mesh grain compositions, 35-47% of 40-mesh grain compositions, 50-62% of 80-mesh grain compositions, and less than 3% of 100-mesh grain composition; (3) performing compression molding on the powder so as to obtain a green brick; (4) drying the green brick, and measuring and controlling technological parameters of the green brick; and (5) glazing, namely a, spraying water onto the surface of the green brick, wherein the usage is 30+ / -6g per tray; b, sprinkling full polished ground coat on the surface of the green brick, wherein the usage is 105+ / -4g per tray, and the specific gravity is 1.89+ / -0.04g / ml; c, jetting ink on the surface of the green brick; d, performing screen printing on protective glaze by adopting a 100-mesh sieve on the surface of the green brick, wherein the specific gravity is 1.55+ / -0.02g / ml; and e, sprinkling full polished glaze on the surface of the green brick, wherein the usage is 105+ / -4g per tray, and the specific gravity is 1.89+ / -0.04g / ml,firing, and polishing, thereby obtaining the full polished glazed tiles. According to the process for producing the full polished glazed tiles disclosed by the invention, the quality control is accurate, the yield is high, the production quality is stable, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics processing, in particular to a production process of fully glazed tiles. Background technique [0002] In the existing production process of full-glazed tiles, glaze production and blank pressing are usually controlled separately, and the final bricks often need to be graded. If there are full-glazed tiles that fail to meet the minimum quality requirements When they are treated as waste bricks, the rate of waste products is often high, especially the unreasonable operation in the process of blank and glaze line processing, and the indirect factors affecting the quality of bricks in different steps are not considered uniformly. Complete and accurate measurement and control of the production quality of fully polished glazed tiles, its parameters cannot be effectively measured and controlled, resulting in low production quality of fully polished glazed tiles, low yield, and easy to cau...

[0002] In the existing production process of full-glazed tiles, glaze production and blank pressing are usually controlled separately, and the final bricks often need to be graded. If there are full-glazed tiles that fail to meet the minimum quality requirements When they are treated as waste bricks, the rate of waste products is often high, especially the unreasonable operation in the process of blank and glaze line processing, and the indirect factors affecting the quality of bricks in different steps are not considered uniformly. Complete and accurate measurement and control of the production quality of fully polished glazed tiles, its parameters cannot be effectively measured and controlled, resulting in low production quality of fully polished glazed tiles, low yield, and easy to cause waste and increase production costs.
