Problems solved by technology

Therefore, in the production of white or light-colored glazed tiles, sanitary ware and pure white polished tiles, iron removal is an important process, and a large amount of iron impurity waste is produced. These wastes are mainly composed of iron oxides, such as Iron oxide, ferric oxide, etc. are often discarded directly because they are difficult to use, which affects the environment and wastes resources

Embodiment 1

[0025] The mass percent composition of metal glaze raw materials is: 36.1% of quartz, 2.7% of iron phosphate, 7.1% of aluminum oxide, 5.1% of calcite, 13.9% of albite feldspar, 8.0% of kaolin, 22.6% of glass powder, 3.0% iron impurities and 1.5% copper oxide are recovered from sanitary ceramics, the sum of the above components is 100%, and then CMC (sodium carboxymethyl cellulose) not exceeding 2% of the total mass of the above components is added. Among them, the recovery of iron impurities in sanitary ceramics is to pass the iron impurities recovered by the conventional sanitary ceramics iron removal process through an 80-mesh sieve to remove large particles of impurities, and then calcine at 350°C to remove organic impurities, grease and other pollutants, and then Grind to a particle size ranging from 100 mesh to 250 mesh.

Abstract

The invention discloses a metal glaze prepared from iron impurities recovered from sanitary ceramics. The metal glaze comprises the components: quartz, iron phosphate, aluminum oxide, calcite, albite,kaoline, glass powder, iron impurities recovered by using a sanitary ceramic iron removal process, copper oxide and sodium carboxymethyl cellulose, wherein the particle sizes of the iron impurities recovered by using the sanitary ceramic iron removal process are 100-250 meshes. The invention further provides a method for preparing metal glaze from iron impurities recovered from sanitary ceramics,and the method comprises the steps: sieving, calcining and grinding the iron impurities recovered from sanitary ceramics, then, mixing the iron impurities recovered from sanitary ceramics with othercomponents, and carrying out ball milling to obtain glaze slip; spraying the glaze slip on the surfaces of the sanitary ceramics; and carrying out high-temperature firing to form a metal glaze layer with a bronze metal texture. On one hand, the recycle of sanitary ceramic iron removal wastes is realized, and the energy source is saved; and on the other hand, an individual sanitary ceramic productis obtained, and the demand of diversification is met.

Description

technical field [0001] The invention relates to the field of sanitary ceramics, in particular to a metal glaze prepared by recycling iron impurities from sanitary ceramics and a method thereof. Background technique [0002] The content of iron element in the earth's crust is as high as 4.2%. During the production of raw materials for sanitary ceramics and their processing and transportation, iron and its oxides will inevitably be brought in, which will affect the quality of ceramic products, especially in white or light-colored blanks. The presence of iron in the glaze will seriously affect the appearance, color and finish of the product. For example, the iron with large particles (such as rust) in the raw materials will turn into black and yellow spots after calcination, and the fine iron powder may reduce the whiteness of the brick or glazed surface under high temperature calcination, causing air bubbles and pinholes in the glazed surface. And other issues. Therefore, in...
