Problems solved by technology

The main raw material of the glaze comes from natural ore components, which have high hardness. At present, the commonly used particle size control method is the combination of crushing and ball milling, but the ball milling method takes a long time, and the crushing particle size of the crusher is limited, and the wear of the crushing blades It is more serious, so it is necessary to consider the ball milling time and the service life of the pulverizer blade while controlling the glaze particle size

Embodiment 1

[0028] A kind of glazing process of daily-use ceramic green body, comprises the following steps:

[0029] (1) Glaze preparation: Mix the glaze fully and put it into a vacuum bag. After vacuuming, place it in a -15°C environment and freeze it for 5 hours. Take out the glaze and use a pulverizer to make a 270-mesh micropowder. Heat at a heating rate of -10°C / min to 115-125°C and mix for 15 minutes, then cool naturally to room temperature;

[0030] (2) Preparation of glaze slurry: Heat water to 40-50°C and keep stirring for 10 minutes, then add the glaze after the above treatment, continue to keep warm and stir at 40-50°C for 30 minutes, and let it stand for 1 hour after natural cooling to room temperature. Pass through a 270-mesh sieve, transfer the obtained filtrate into a ball mill, and ball mill until the output particle size is less than 30 μm, and then obtain the glaze slurry; wherein, the mass ratio of the glaze material to water is 1:2;

[0031] (3) Automatic glazing: th...

Abstract

The invention discloses a glazing process for a daily ceramic blank and relates to the technical field of daily ceramics. The glazing process comprises the following steps: (1) preparing a glaze; (2)preparing glaze pulp; (3) performing automatic glaze application; (4) polishing the bottom of the blank. In the glaze preparation process, the glaze is vacuumed and frozen to reduce the crushing granularity of the glaze, the abrasion degree of the glaze to blades of a crushing machine in the crushing process is reduced, and meanwhile the crushing time is shortened; due to adoption of the glaze application process, the glaze application quality is ensured, a glaze surface which is smooth and fine in hand feeling, clear and bright in gloss and fluent and smooth in line is formed on the surface of a ceramic blank after the glaze is sintered, and thus the market competitiveness of a ceramic product is improved.

Description

Technical field: [0001] The invention relates to the technical field of daily-use ceramics, in particular to a glazing process for a daily-use ceramic body. Background technique: [0002] Daily-use ceramics, as the name suggests, refer to the indispensable daily-use porcelain in people's daily life. Ceramic tableware, tea set, coffee set, wine set, table set, etc. are the most contacted by people in daily life, which are widely used. The glazing process refers to the process of applying glaze slurry on the surface of the formed ceramic body to form a glaze layer. It has the following functions: to improve the surface properties of ceramic products, make the surface of the product smoother and less prone to contamination; the glaze layer can reduce the surface of the body. Water absorption can prevent the penetration of liquid and gas; the glaze layer can improve the mechanical strength of the product and prolong the life of the ceramic product; it can improve the chemical s...
