A kind of grouting process of ceramic green body

Abstract

The invention discloses a ceramic green body grouting technology. The ceramic green body grouting technology comprises the steps of high-pressure tank circulation, low-pressure grouting pipe circulation, slow filling, rapid filling, high-pressure grouting, slurry discharge, consolidation and the like. By the adoption of the ceramic green body grouting technology, automatic control can be achieved, the production efficiency is improved, the production period is shortened, the yield of green bodies is improved, the quality of the green bodies is stabilized, and the labor intensity is lowered.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a grouting process for a ceramic green body. Background technique [0002] In the field of ceramic manufacturing, especially in the field of sanitary ware manufacturing, blank forming is an important step. The grouting process is the core link of green body forming. In the prior art, the body grouting process has gone through a process from manual grouting to low-pressure grouting and then to high-pressure grouting. Manual grouting has high labor intensity and low production efficiency, and the product quality largely depends on the proficiency and experience of the grouting workers, so the quality of the sanitary ware ceramic body can hardly be guaranteed. As a result, some enterprises have gradually developed a low-pressure grouting process. The grouting pressure is generally 0.3 to 0.7Mpa. In the low-pressure pouring process, although the heavy manual labor is eliminated...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the lack of sufficient pipeline circulation before grouting, the green body may be defective due to the physical properties of the residual mud being different from the new mud or the presence of gas;

[0005] 2. During high-pressure grouting, the pressure is insufficient, resulting in too long high-pressure grouting time and low production efficiency;

[0006] 3. In the technical solution of this patent, the mud is discharged by tilting the mold by mechanical means, which consumes a lot of energy and takes a long time, and the mud discharge is not clean;

[0007] 4. The mud is discharged after consolidation, so that the thickness of the green body and the quality of the green body cannot be guaranteed.
