Problems solved by technology

Then in the existing formula and processing method, when the glaze slurry particle distribution -10u exceeds 65%, the glaze layer is easy to produce defects such as cracks and glaze shrinkage; The vibration force is large, it is easy to shift the screen wire, and the mesh is partially deformed, so that the thicker colored impurities will also pass through the screen), which cannot effectively remove the colored impurities in the raw materials, especially some non-magnetic colored impurities. Firing at high temperature will cause spots on the glazed surface of the product, which will affect the appearance quality of the product

Embodiment 1

[0023] A kind of glaze material for double-layer glazing, its specific formula is shown in Table 1.

[0024] Table 1 Glaze formula table

[0025] Unit: grams

[0026]

[0027]

[0028] The glaze is prepared by the following method, which specifically includes the following steps:

[0029] (1) The preparation method of bottom glaze, comprises the following steps:

[0030] 1) Mix the components in the glaze formula, pass through wet iron removal, ball milling, and pulping in sequence, then pass through a 140-mesh static sieve, then pass through an electric iron removal, a 200-mesh vibrating screen, and an iron removal tank in turn, and then pass through 140 mesh static sieves, obtain slurry A;

[0031] 2) Add carboxymethyl cellulose sodium to the slurry A and stir evenly to obtain the bottom glaze; the carboxymethyl cellulose sodium accounts for 0.15% to 0.3% of the total mass of the slurry A;

[0032] (2) The preparation method of face glaze, specifically comprises th...

Embodiment 2

[0038] A method for applying a glaze in double-layer glazing (the glaze is prepared by the method described in Example 1), specifically comprising the following steps: first spraying the bottom glaze on the surface of the green body, the thickness of the sprayed glaze is 0.15-0.20 mm ; Then spray the surface glaze on the green body, and the thickness of the spray glaze is 0.6-0.8 mm.

Abstract

The invention relates to the technical field of ceramics, and discloses a preparation method of a glaze for double-layered glazing. The glaze is prepared from, by weight, 18-26 parts of potash feldspar, 1.5-3.0 parts of aluminium oxide, 2.5-4.5 parts of kaolin, 10-16 parts of calcite, 35-42 parts of quartz, 2-5 parts of zinc oxide, 3-6 parts of dolomite, 3-6 parts of frit, 8-13 parts of zirconiumsilicate, and 35-45 parts of water. The preparation method of the glaze includes preparation methods of a base coat and a face coat. During the manufacturing processes of the ground coat and the facecoat, one static screen is arranged in front of and behind an iron removing sieve (vibrating sieve), colorful impurities can be effectively intercepted. The invention adopts double-layered glazing, the method can effectively improve the glaze glossiness, flatness and pollution resistance of a health ceramic sanitary ware; thus the glaze stain defect is reduced, and the purposes of improving product quality and customer satisfaction are reached.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a glaze material for double-layer glazing, a preparation method and an application. Background technique [0002] With the improvement of people's living standards, the demand for sanitary ware is increasing, and the requirements for product quality (such as: style, function, glaze gloss, flatness, no stain resistance, pure glaze color without spots, etc.) are also increasing. high. The development of high-quality sanitary ware has a broad market prospect. The glaze luminosity, flatness, and anti-fouling performance of sanitary ware have a lot to do with the glaze formula, particle size, and glaze thickness. Luminosity, flatness, and antifouling properties have been significantly improved. Then in the existing formula and processing method, when the glaze slurry particle distribution -10u exceeds 65%, the glaze layer is easy to produce defects such as cracks and glaze shrinka...
