Problems solved by technology

Different glazing methods will produce different effects. At present, in order to enhance the quality and durability of ceramics, when preparing ceramics, research is mostly carried out from the formulation and firing process of the body and glaze, and seldom enhances the durability of ceramics from the glazing method.

Embodiment 1

[0017] A glazing method for enhancing the durability of ceramics, comprising the steps of:

[0018] (1) Wet glaze preparation: add water 3 times the weight of the glaze to the glaze, stir evenly, and freeze at -23°C for 10 hours to make the glaze evenly watered and easy to grind. After taking it out, add 3 times the weight of the glaze Double the amount of anhydrous alcohol, at a temperature of 42°C and a humidity of 66%, the grinding is even and without alcohol, it can speed up the thawing of the glaze and keep the color bright, the particle size is 60-70 μm, and the glaze must be sprayed; the glaze , made of the following raw materials in parts by weight: silicon dioxide 43, aluminum oxide 10, scandium oxide 7.1, boron oxide 5.7, lanthanum oxide 5.6, palladium oxide 5.2, rhodium chloride 4.7, rust stone 4.1, diopside 3.7, Pigment 3.1;

[0019] (2) One-time glazing: Spray the glaze to be used evenly on the surface of the body with a thickness of 0.3mm, and place it in an env...

[0024] A glazing method for enhancing the durability of ceramics, comprising the steps of:

[0025] (1) Wet glaze preparation: Add water 4 times the weight of the glaze to the glaze, stir evenly, and freeze at -22°C for 11 hours to make the glaze evenly watered and easy to grind. After taking it out, add 4 times the weight of the glaze Double the amount of absolute alcohol, at a temperature of 43°C and a humidity of 67%, grind evenly, without alcohol, can speed up the thawing of the glaze, keep the color bright, the particle size is 60-70 μm, and the glaze must be sprayed; the glaze , made of the following raw materials in parts by weight: silicon dioxide 44, aluminum oxide 11, scandium oxide 7.7, boron oxide 6.8, lanthanum oxide 6.3, palladium oxide 5.8, rhodium chloride 5.1, rust stone 4.6, diopside 4.7, Pigment 3.6;

[0026] (2) One-time glazing: Spray the glaze to be used evenly on the surface of the green body with a thickness of 0.3mm, and place it in an environment wit...

Embodiment 3

[0031] A glazing method for enhancing the durability of ceramics, comprising the steps of:

[0032] (1) Wet glaze preparation: add water 5 times the weight of the glaze to the glaze, stir evenly, and freeze at -21°C for 12 hours to make the glaze evenly watered and easy to grind. After taking it out, add 5 times the weight of the glaze Double the amount of anhydrous alcohol, at a temperature of 44°C and a humidity of 68%, the grinding is uniform, without alcohol, which can speed up the thawing of the glaze and keep the color bright. The particle size is 60-70 μm, and the glaze must be sprayed; the glaze , made of the following raw materials in parts by weight: silicon dioxide 45, aluminum oxide 12, scandium oxide 8.5, boron oxide 7.8, lanthanum oxide 7.3, palladium oxide 6.6, rhodium chloride 6.1, rust stone 5.3, diopside 4.9, Pigment 4.3;

Abstract

The invention mainly relates to the technical field of ceramic glaze processing, and discloses a glazing method for enhancing ceramic durability. The glazing method includes the steps: wet glaze preparation; primary glazing; dry glaze preparation; secondary glazing; firing and drying. The method is simple and convenient to operate, glaze and a green body are closely combined, expansion coefficients are matched, surfaces are smooth and uniform, colors are bright, corrosion resistance is high, the service life is prolonged by 12.4%, and economic income is improved by 26.7%. The glaze is frozen by adding water, grinding is facilitated, anhydrous alcohol is added, the glaze is grinded in a high-temperature dry environment, unfreezing of the glaze is accelerated, and the bright colors are kept. The green body is placed in a high-temperature and high-humidity environment after primary glazing, adsorption of the green body for the glaze is promoted, needle holes and bubbles are decreased, and the service life is prolonged. The sprayed glaze is freeze-dried, the colors of the glaze are kept bright, adsorptivity of the glaze is enhanced, the glaze is applied by dry pressing, so that a glaze layer is smooth and uniform, and durability is improved. The green body is fired at low temperature after the glaze is applied, durability of the green body is improved, environments are protected, and energy is saved by 9.6%.

Description

technical field [0001] The invention mainly relates to the technical field of ceramic glaze processing, in particular to a glaze application method for enhancing the durability of ceramics. Background technique [0002] Glazing technology is a kind of ancient ceramics manufacturing technology. It refers to the process of applying glaze slurry on the surface of the formed ceramic body. The methods include dipping glaze, swaying glaze, pouring glaze, brushing glaze, blowing glaze, spraying glaze, There are many kinds of wheel glazes. Different glazing methods will produce different effects. At present, in order to enhance the quality and durability of ceramics, when preparing ceramics, research is mostly carried out from the formulation and firing process of the body and glaze, and seldom enhances the durability of ceramics from the glazing method. . Contents of the invention [0003] In order to make up for the defects of the prior art, the object of the present invention...
