Problems solved by technology

So many and huge piles of coal gangue not only adversely affect the air, landscape, and environment of the city, but also occupy a lot of high-quality land resources, causing water pollution and soil damage. So far, it has not been found that there are large amounts of coal gangue in the billet and glaze. The report of using coal gangue waste to prepare porcelain sanitary ceramics with low expansion and high infrared function, so the preparation of high infrared function ceramic materials by using coal gangue has great innovation and application prospects

Abstract

The invention relates to vitreous building sanitary ceramic with a low-expansion and high-infrared function prepared by waste gangue. The vitreous building sanitary ceramic comprises the following raw materials: a green body: 32-45% of Pingxiang gangue, 26-42% of Guangfeng black talc and 25-32% of bauxite, and glaze: 32-36% of Pingxiang gangue, 12-20% of Guangfeng black talc, 35-40% of spodumene, 0-3% of zirconium silicate, 3-6% of quartz and 3-6% of attaclay, and is prepared by compounding, ball milling, mouldiness, slip casting, glazing, dryness and firing. The ceramic takes the industrial waste gangue as the principal raw material, so that the scarce ceramic raw materials are saved; the ceramic has a treatment assistance effect; particularly, since the ceramic is very low in thermal expansivity, a product of the ceramic is good in thermal shock resistance and long in service life; and the ceramic has a wide application prospect in various sanitary ceramic products.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to low-expansion, high-infrared function porcelain building sanitary ceramics prepared from waste coal gangue in Pingxiang, Jiangxi Province and a preparation method thereof. Background technique [0002] In the past two decades, my country's building sanitary ceramics industry has developed rapidly. Since the early 1990s, my country's building sanitary production has been ranked first in the world. However, as sanitary ware products that must be used by every household, most of the products in the past were ceramics, and the microstructure of the products after firing was mainly quartz and mullite crystal phases, often because of the high water absorption rate of the product itself and the thermal expansion coefficient Large (>6×10 -6 / °C), poor thermal shock resistance and other defects. After many years of use in an environment with a lar...
