example 1

[0021] A kind of fine porcelain for daily use with high light transmittance, its body includes the following mineral components (by weight): 25% of Guangxi porcelain clay, 10% of potassium feldspar, 10% of quartz powder, 40% of kaolin, 5% of clay, Alumina 5% and Bentonite 5%. Detected through analysis, the green body prepared contains following chemical composition (by weight percentage): SiO 2 55.68%, Al 2 o 3 29.78%, CaO2.34%, MgO0.24%, K 2 O2.42%, Na 2 O1.36%, Fe 2 o 3 0.14%, TiO 2 0.02%. Described Guangxi china clay ore contains following chemical composition (by weight percentage): SiO 2 60%, Al 2 o 3 22%, CaO5.5%, MgO0.6%, K 2 O0.15%, Na 2 O0.5%, Fe 2 o 3 0.15%, TiO 2 0.01%.

[0022] The production process of the high-transmittance daily-use fine porcelain is as follows: crush various mineral raw materials and mix them according to the ratio, add water and ball mill for 29 hours according to the ratio of material: water = 1:1, sieve with a 300-mesh stainl...

example 2

[0025] A kind of fine porcelain for daily use with high light transmittance, its body includes the following mineral components (percentage by weight): 28% of Guangxi porcelain clay, 8% of potassium feldspar, 9% of quartz powder, 38% of kaolin, 5% of clay, Alumina 5% and Bentonite 7%. Detected through analysis, the green body prepared contains following chemical composition (by weight percentage): SiO 2 55.96%, Al 2 o 3 29.69%, CaO2.45%, MgO0.28%, K 2 O2.32%, Na 2 O1.27%, Fe 2 o 3 0.12%, TiO 2 0.02%. The chemical composition of described Guangxi china clay ore is identical with embodiment 1.

[0026] The production process of this high-transmittance daily-use fine porcelain is as follows: crush various mineral raw materials according to the proportion and mix them, add water and ball mill for 28 hours according to the ratio of material: water = 1:1, sieve with a 300-mesh stainless steel screen, and remove iron , pressure filtration, the water content of the mud bar af...

Abstract

The invention discloses a kind of high transmittance fine household porcelain and a production technology thereof. The porcelain clay in Guangxi is added in the common raw materials and bone meal and talcum powder are not needed to add. The green body comprises the following components by weight percent: 20-35% of porcelain clay in Guangxi, 5-20% of potassium feldspar, 10-20% of quartz powder, 5-10% of alumina, 30-50% of kaolin, 5-10% of clay and 4-12% of bentonite. The production technology of the high transmittance fine household porcelain comprises the following steps: crushing and mixing the raw materials, performing ball-milling, sieving, deironing, performing filter-pressing, smelting, aging, refining, rolling or performing slip casting, enameling, and using an oxidizing atmosphere for single firing in a kiln. By adopting the formulation selected by the invention, the mud has extremely good plasticity so that the mud can be used to form the thinner eggshell porcelain and be suitable to prepare various irregular products with peculiar shapes. The products have high transmittance and strength, and smooth and delicate porcelain glaze.

Description

technical field [0001] The present invention relates to a kind of porcelain and its production process, more specifically, the present invention relates to a kind of fine porcelain for daily use with high light transmittance and its production process. Background technique [0002] my country has a history of thousands of years of ceramic culture. For thousands of years, the porcelain makers of all dynasties have been working hard to promote technological innovation and innovation in ceramic production, striving to produce low-cost, high-end daily-use porcelain and gain greater business opportunities. However, in the existing ceramic preparation technology, almost most of the high-grade daily-use porcelain can be realized through secondary firing, which still cannot achieve the goals of low loss, low energy consumption and low cost. Magnesia and bone china. [0003] In the existing technology, it is not possible to adopt the general one-time firing technology, and use ordin...
