Fire-resistant domestic ceramics

Abstract

The invention discloses fire-resistant domestic ceramics, which are manufactured from the following raw materials, by weight part, 13-15 of gypsum, 5-7 of calcium oxide, 13-15 of alumina magnesia spinel, 16-20 of sericite, 6-9 of aluminium powder, 5-7 of silica sol, 7-9 of activated carbon, 1-2 of propenyl alcohol, 40-45 of coal ash, 35-40 of white glaze spheres, 6-8 of waste glass, 10-14 of maifan stone, 21-25 of green tea, 14-17 of orange peels, 6-8 of shell powder, 4-6 of shrimp shell powder, 0.2-0.3 of polyvinyl alcohol, 0.2-0.3 of tributyl phosphate, and a proper amount of deionized water. The fire-resistant domestic ceramics are high in strength, have certain shock resistance, are good in particle adhesion, and thus, the problem that conventional ceramics are damaged and prone to crack is overcome. The fire-resistant domestic ceramics are worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of daily-use ceramics, in particular to a refractory daily-use ceramic product. Background technique [0002] my country is not only rich in mineral resources, but also the world's largest coal producer and coal consumer. In recent years, my country's thermal power generation has developed rapidly, most of which use coal as fuel, with a power generation capacity of 130 million kW·h. The proportion reached 79.6%, which led to an increase in fly ash emissions year by year. At the end of 2010, the emission reached nearly 300 million tons, and the emission of a large amount of fly ash has received more and more attention. Since 1987, my country has started to use fly ash as a breakthrough in the comprehensive utilization of resources, and its comprehensive utilization has become a long-term policy for economic and social development. Waste glass substances have strong chemical stability, do not rot, burn, and c...
