Ordinary fine procelain

Abstract

The invention relates to procelain production and aims to provide an ordinary fine procelain featuring low firing temperature and reduced production cost. The ordinary fine procelain of the invention comprises the following components in percentage by weight: 9-12% of Guangxi soil, 5-10% of Jingxing soil, 2-6% of Shanyin soil, 2-7% of Yusi soil, 2-8% of Tang county soil, 8-14% of Longyan soil, 22-28% of quartz, 24-30% of Datong soil, 8-14% of feldspar and 6-8% of fine bone china waste powder. Blank is crushed, processed into fine powder of 100 meshes and ball-milled in a wet-type ball mill while being added with water, blank: ball: water=1:2.5:1; the mixture is levigated for 18-20 hours; the mixture passes through a sieve of 250 meshes, the fineness of the mixture is 0.8%, the mixture is dehydrated by a mud press to have a water content of 21% and then vacuum pugging is carried out on the mixture for twice at a vacuum degree more than or equal to 0.09MPa.In the invention, the fine bone china waste powder is added to the production of the ordinary fine procelain, therefore the firing temperature of the ordinary fine porcelain in the invention is reduced by about 30 DEG C compared with the firing temperature of the traditional ordinary fine porcelain.

Description

technical field [0001] The invention relates to the production of ceramics, in particular to a batching of ordinary and fine porcelain and a production process thereof. Background technique [0002] Kiln firing is a key step in ceramic production, and the control of firing temperature is directly related to the quality of ceramics. In the traditional production process, the kiln firing temperature is relatively high, usually 1250°C-1320°C. Excessively high firing temperature not only consumes a lot of energy, but also easily causes surrounding environmental pollution. Therefore, people have been working hard to explore ways to reduce the firing temperature. For example, the Chinese invention patent with the notification number CN100360461C discloses a medium-temperature high-alumina reinforced porcelain and its production process. The green body includes Datong soil, weathered potassium feldspar, oxide Aluminum, Hunan washed mud, Jiangxi lithium porcelain stone powder, Huna...

Problems solved by technology

In the traditional production process, the kiln firing temperature is relatively high, usually 1250°C-1320°C. Too high firing temperature not only consumes a lot of energy, but also easily causes surrounding environmental pollution

Therefore, people have been working hard to explore ways to reduce the firing temperature. For example, the Chinese invention patent with the notification number CN100360461C discloses a medium-temperature high-alumina reinforced porcelain and its production process. The green body includes Datong soil, weathered potassium feldspar, oxide Aluminum, Hunan washed mud, Jiangxi lithium porcelain stone powder, Hunan black feldspar, calcined talc, Jiepai soil, quartz, Guizhou soil, the production process includes ingredients, adding water ball mill, sieving iron removal, press filtration, rough smelting, stale, scouring , molding, drying, fine-graining, and kiln firing. This invention reduces the firing temperature to 1230-1280°C by adding mineralizer lithium china stone powder. However, this invention has the disadvantage of high cost and is not suitable for large-scale application.
