preparation example Construction

[0034] The preparation method of the above-mentioned enamel slurry includes the following steps: adding 100 parts of enamel glaze, 30-50 parts of glass powder, 0.3-0.5 parts of borax, 0.2-0.5 parts of sodium nitrite, 5-7 parts of clay, and 0.5-1 part of bentonite. 1 part, 0.5-1 part of sodium fluorosilicate, and 35-40 parts of water to obtain a mixture, which is then added to ball and ball mill to obtain enamel slurry.

[0035] Preferably, in the above-mentioned preparation method of enamel slurry, the zirconia balls are a mixture of two kinds of balls with diameters of 5 mm and 2 mm. The two sizes of balls are mixed for easy ball milling. The mass ratio of the zirconia balls to the mixture is 1-1.2:1. If the ratio of the total mass of the ball to the total mass of the mixture is large, each time the material is less abrasive and the ratio is small, the grinding time will be longer.

[0036] Preferably, in the above-mentioned preparation method of enamel slurry, the rotation...

Abstract

The invention specifically relates to an enamel glaze material, an enamel slurry, and a preparation method and an application thereof. The invention relates to the technical field of enamel materials. The invention aims at solving a technical problem of providing an enamel glaze material. The enamel glaze material is prepared by uniformly mixing the following raw materials, by weight: 40-45 parts of quartz sand, 9.5-10 parts of feldspar powder, 24-26 parts of borax, 2.5-3 parts of cryolite, 5.5-7.5 parts of sodium nitrate, 3.5-4 parts of lithium carbonate, 3.5-4.5 parts of fluorite powder, 2-4 parts of calcium carbonate, 3-4 parts of cobalt nitrate, 0.8-1.2 parts of nickel nitrate, 2-2.2 parts of manganese oxide, and 3.4-3.8 parts of zirconium dioxide. The enamel glaze material can be combined well with glass powder to produce the enamel slurry. The enamel slurry can be coated on the surface of a metal substrate to form an enamel coating. The coating has the advantages of smooth glaze surface, good gloss, no bubble, and no scaling. The coating can be firmly combined with a carbon steel substrate, and has good acid resistance.

Description

technical field [0001] The invention specifically relates to an enamel glaze, an enamel slurry and a preparation method and application thereof, and belongs to the technical field of enamel materials. Background technique [0002] Enamel coating refers to the one or more layers of enamel glaze coated on the metal surface when fired at high temperature, the metal matrix and the enamel glaze undergo physical and chemical reaction at high temperature, crystals are precipitated at the interface and chemical bonds are formed. Layer dense coating. It has both the strength and elongation of steel and the excellent properties of acid and alkali corrosion, oxidation resistance, easy washing, non-toxic, odorless, smooth and wear-resistant of glass, so enamel is widely used in chemical reactors, household appliances, kitchen utensils, For building exterior walls, sanitary facilities, etc., it can withstand the corrosion of various concentrations of inorganic acids, organic acids, weak...
