The invention discloses double-layer fancy glaze with chapped ground texture and a preparation method of the double-layer fancy glaze, and relates to the technical field of ceramic glaze. The double-layer fancy glaze is composed of a ground glaze layer and a cover glaze layer. The ground glaze raw materials comprise potassium feldspar, kaolin, calcite, quartz, dolomite, zinc oxide and pigment; the cover glaze raw materials comprise potassium feldspar, waste porcelain powder, blank powder, chinastone, limestone, sepiolite, quartz, zirconium silicate with the particle size D50 being less than or equal to 1.0 mu m and pigment. The preparation method comprises the following steps: respectively carrying out ball milling to prepare ground glaze slip (32-40 baume degrees) and cover glaze slip (51-53 baume degrees); spraying ground glaze on the green body, drying, and then soaking with cover glaze; and finally, sintering at the temperature of 1250-1270 DEG C in a reducing atmosphere. Through the synergistic effect of the sepiolite and other components, the cover glaze has high surface tension, forms a microcrack network during drying, generates controllable glaze shrinkage during firing, forms a three-dimensional chap texture with crack width of 1-5mm and strong curled and raised crack edges, and meanwhile, the ground glaze completely covers a green body, so that the product practicability is ensured.

The invention discloses a Xinjiang porcelain glaze and a porcelain preparation method, and relates to the technical field of ceramic materials, the porcelain glaze takes 70%-80% of Xinjiang local Sanjianlake porcelain stone as a main body, and calcite (9%-15%) and white feldspar (6%-8%) are cooperatively blended. The preparation method comprises the steps of basic glaze preparation, glaze slip ball milling, glazing and five-stage firing. The firing system comprises the following steps in sequence: oxidizing and dehumidifying at 0-500 DEG C, oxidizing and decomposing at 500-1000 DEG C, reducing and coloring at 1000-1300 DEG C, preserving heat at 1300 DEG C and cooling along with a kiln. Through unique raw material ratio and accurate firing control, iron and titanium elements in Xinjiang minerals are successfully utilized, the porcelain with bright and smooth glaze and Xinjiang characteristics is stably fired, the problem of glaze defects caused by the fact that a traditional process is not matched with Xinjiang raw materials is solved, the yield is high, and the production cost is low. And a reliable technical path is provided for realizing high-valued industrial development of Xinjiang ceramic resources.

Environmentally, it eliminates deforestation and reduces the carbon footprint by avoiding harmful mining practices. Structurally, porcelain provides superior strength, fire resistance, and long-lasting durability, with a lifespan exceeding 25 years. This invention offers a sustainable, hygienic, and durable alternative to traditional kitchen materials, promoting a safer and more reliable solution for modern kitchen designs.

The present application relates to the technical field of the production of sanitary ceramics, and in particular relates to a green body for eliminating sintering blisters from a high-pressure formed ceramic, and a preparation method therefor. On the basis of the mass percentage of raw materials, the green body comprises: 20%-25% of kaolin, 1%-3% of quartz, 5%-8% of ball clay, 17%-27% of high-alumina porcelain stone, 3%-8% of waste porcelain, 3%-10% of low-glaze recycled mud, 0%-5% of raw porcelain clay, 10%-15% of water-washed porcelain clay, 10%-21% of spodumene tailings and / or microcline, and 2%-5% of wollastonite. The green body is obtained by means of high-pressure slip casting, drying and sintering. In the present application, the formation and blocking mechanisms of sintering blisters are precisely determined, thereby effectively controlling the defect of sintering blisters in high-pressure formed sanitary ceramic products. In addition, a large number of industrial solid waste raw materials such as waste porcelain, waste mud and spodumene tailings are used in the formula of the green body of the present application, which helps to reduce the accumulation of industrial solid waste, reduce environmental pressure and promote the sustainable development of the sanitary ceramics industry.

This invention provides a manufacturing process for a double-layered insulated ceramic cup based on 3D printing. The manufacturing process includes the following steps: grinding, drying, and mixing titanium dioxide and potassium carbonate; preparing a modifier through high-temperature reaction; adding the modifier to modify porcelain stone, kaolin, and clay; adding yttrium oxide and calcium oxide and ball milling and mixing; modeling and 3D printing a double-layered ceramic green body; and sintering the double-layered ceramic green body. This invention uses kaolin, clay, porcelain stone, and porcelain clay as raw materials, and utilizes a 3D clay printer to print the inner and outer layers of the ceramic cup, with the middle layer being a vacuum insulation layer. This effectively prevents heat transfer, achieving heat insulation and anti-scalding effects, thereby improving the practicality of the ceramic cup. Furthermore, the 3D printing process for producing double-layered ceramic cups is simple and reduces the complexity of the molding process.
