Low-temperature glaze-fired ceramic product and preparing method thereof

Abstract

The invention provides a low-temperature glaze-fired ceramic product and a preparing method thereof, and relates to the technical field of ceramic products. The low-temperature glaze-fired ceramic product is obtained by coating a ceramic blank with low-temperature glaze and drying and firing the ceramic blank. The ceramic blank comprises, by mass, 30-40 parts of coal gangue, 40-50 parts of chinastone, 5-10 parts of bentonite, 3-8 parts of talc, 6-15 parts of wollastonite, 4-10 parts of clay, 1-3 parts of quartz and 0.2-0.6 part of sodium polyphosphate. The low-temperature glaze comprises, by mass, 5-15 parts of calcite, 30-40 parts of quartz, 10-20 parts of potassium feldspar, 9-15 parts of kaolin, 10-20 parts of talc, 15-25 parts of barium carbonate, 10-20 parts of borax, 5-10 parts of zinc oxide and 0.1-0.5 part of sodium carboxymethyl cellulose. The prepared ceramic product has high glaze surface hardness, color and luster and heat stability, the firing temperature is lowered, energy conservation and emission reduction are reduced, the adopted raw materials are easy to obtain and low in price, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ceramic products, in particular to a low-temperature glaze-fired ceramic product and a preparation method thereof. Background technique [0002] At present, my country's ceramic products have constituted one of the three indispensable materials in the field of industrial production and science and technology together with metal materials and organic polymer materials. my country's ceramics are exported overseas, and the ceramics used for export are generally undamaged first-class products, which are expensive and bring huge profits to ceramic companies. [0003] In recent years, with the development of industrial and agricultural production and the modernization of people's lives, the energy crisis has become increasingly serious. Countries around the world have vigorously advocated "energy saving and emission reduction". Fuel consumption, in foreign countries, fuel consumption accounts for about 25% of ...

AI Technical Summary

Problems solved by technology

[0004] In the process of ceramic production, there are many second-class, third-class and defective products with slight defects in quality. Most of these products are sold at low prices in China, or directly sold as refractory materials, which greatly affects the income of manufacturers. benefit

Some manufacturers even remelt some defective products that are severely damaged, and the cost of recycling is higher than the cost of repurchasing clay production, so some manufacturers choose to discard the defective products directly
