Problems solved by technology

However, due to the special firing system of sanitary ceramics (high temperature and long-term firing), the known glaze preparation methods used in ordinary ceramic products are difficult to apply, and it is even more difficult to produce colored glaze surfaces with regular color changes , which limits the diversification and personalized development of ceramic products

Embodiment 1

[0031]

[0032] (1) According to the formula table of glaze material A and glaze material B mentioned above, put them into the ceramic ball mill and carry out ball milling with water as the medium (first add basic glaze, silicon dioxide, dolomite, zinc oxide, zirconium silicate, long For stone powder and ceramic alkali surface and CMC, when the particle size reaches ≤10μm and accounts for 63%, then add vanadium-zirconium blue material, and continue ball milling until the particle size reaches ≤10μm and account for 72%, the ball milling ends), and glaze slurry A and Glaze slurry B; the formula of the basic glaze is: 36.49% feldspar powder for glaze, 24.19% silicon dioxide, 28.59% calcite, 4.26% zinc oxide and 6.47% aluminum oxide powder, plus the sum of the above components 1.5 % 807 frit powder.

[0033] (2) Refining the above-mentioned glaze slurry A and glaze slurry B, the first step is to sieve the glaze slurry, and the glaze slurry needs to be filtered through a 180 mes...

Abstract

The invention discloses a preparation method of blue gradient glaze sanitary ceramic. A glaze material is prepared from basic glaze, silicon dioxide, dolomite, zinc oxide, zirconium silicate, feldsparpowder for glaze, vanadium-zirconium blue and the like; glaze slurry A and glaze slurry B, which have different vanadium-zirconium blue content, are prepared through the glaze material; the glaze slurry A and the glaze slurry B are sprayed on the surface of a sanitary ceramic white body in sequence, wherein the spraying amount of the glaze slurry A is gradually reduced from the top to the bottomof a white body spraying region and the spraying amount of the glaze slurry B is gradually increased from the top to the bottom of the white body spraying region; then the glazed white body is fired in a tunnel kiln at 1202 DEG C to 1250 DEG C for 15h to 18h to obtain a blue gradient glaze sanitary ceramic product. The obtained product meets the processing and utilization performance requirementsof the sanitary ceramic, has a good gradient effect and an extremely good decoration effect, and meets the requirements of individualized bathrooms.

Description

technical field [0001] The invention relates to the field of sanitary ceramics, in particular to a method for preparing blue gradient glazed sanitary ceramics. Background technique [0002] With the continuous development of the real estate industry, the market demand for sanitary ceramics associated with real estate is huge, ceramic production technology and technology are developing rapidly, personalized products in the sanitary ware market are prominent, and product development is beginning to tend to mid-end and high-end. With the improvement of consumers' personal income and appreciation taste, the demand for mid-to-high-end sanitary ceramic products continues to expand. In addition, with the improvement of infrastructure and the increasing investment in residential housing construction, along with the steady growth of GDP, the income of ordinary people has also continued to increase, and they have begun to pay attention to bathroom decoration. The demand for personaliz...
