Manufacturing method of low temperature eco-friendly ceramic

Abstract

The invention relates to the technical field of ceramic manufacture and concretely relates to a low temperature eco-friendly ceramic and a manufacturing method thereof. The low temperature eco-friendly ceramic is prepared from dolomite, smolmitza, dolomite tailings, Xianyou stone, Yongan red soil, calcite, trona and sodium tripolyphosphate. The manufacturing method utilizes dolomite and a large amount of low-price materials such as clay and dolomite tailings as raw materials. Through a reasonable formula and use of additives, a sintering temperature of the low temperature eco-friendly ceramic is reduced to 900-950 DEG C. The manufacturing method realizes one-step sintering, has a low sintering temperature, saves fuel and reduces a production cost. The low temperature eco-friendly ceramic has effects close to those of the traditional dolomite porcelain, is degradable, is safe in use and has active social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a low-temperature environment-friendly ceramic and a manufacturing method. Background technique [0002] Baiyun porcelain has the characteristics of thick texture, strong plasticity, high ornamental value, and safe use. It is a ceramic category that is widely favored in the world. The main material of dolomite porcelain is extracted from dolomite, and the production needs to go through a second firing process. For the first time, it is bisque fired at a low temperature of 750-950°C to volatilize the lead and cadmium remaining in the green body to the maximum extent. In order to ensure the safety of the finished product, the second glaze firing is fired at 1000-1050°C after the ceramic biscuit is glazed. [0003] As the society pays attention to issues such as energy saving, emission reduction and environmental pollution, ceramic manufacturers also pay attention to ...

Problems solved by technology

[0003] As the society pays attention to issues such as energy saving, emission reduction and environmental pollution, ceramic manufacturers also pay attention to the transformation to the direction of one-time firing and low-temperature environmental protection in ceramic production. Therefore, a variety of improved lightweight ceramics have appeared on the market. Publication No. CN 104230309A discloses a single-firing lightweight ceramic, which is made of kaolin, low-temperature sand, pyrophyllite, clay, wollastonite, feldspar, and magnesia. This light ceramic is made of kaolin, magnesium Raw materials such as clay and wollastonite have replaced dolomite to achieve one-time firing of lightweight ceramics, but there are still many problems. First, the price of raw materials such as kaolin, magnesium clay, and wollastonite is higher than that of dolomite. The production cost increases and the market advantage decreases. The second is that the lack of dolomite in the ceramic body reduces the plasticity of the body. The third is that the effect of firing such light ceramics is quite different from that of traditional dolomite porcelain.
