Siliceous attapulgite volcaniclastic refractory brick

Abstract

The invention discloses a siliceous attapulgite volcaniclastic refractory brick. The technical scheme includes that the siliceous attapulgite volcaniclastic refractory brick is made of high-viscosity attapulgite clay powder, attapulgite clay tailings, volcaniclastic rock mixture, quartzite, waste siliceous bricks, opal and bentonite tailings. A finished product of the siliceous attapulgite volcaniclastic refractory brick is made by uniformly stirring the ingredients, pressing, airing, calcining, cooling and packaging. The siliceous attapulgite volcaniclastic refractory brick has the advantages of high particle strength, high resistance to acidic slag, high thermal shock stability and high refractoriness. The siliceous attapulgite volcaniclastic refractory brick is made of a great quantity of various wastes, so that resource utilization rate is increased beneficially, the wastes are turned into wealth, land occupation can be reduced, environmental protection and purification are achieved, energy is saved, production cost is lowered, and economic benefit is improved. Further, the siliceous attapulgite volcaniclastic refractory brick is applicable to acidic refractory engineering.

Description

technical field [0001] The invention relates to a refractory material, in particular to an attapulgite pyroclastic rock siliceous refractory brick. Background technique [0002] Refractory materials are mainly made of natural ores such as bauxite, silica, magnesite, and dolomite after processing. [0003] 80% of my country's mineral resources are associated mines, a large amount of valuable resources are stored in tailings, and tailings stockpiles require a large amount of land. Many tailings ponds have been used beyond the time limit or overloaded, or even operated in violation of regulations, which has caused great safety hazards in the tailings ponds and posed a serious threat to the property and life safety of people in surrounding areas. [0004] In addition to attapulgite, attapulgite clay often contains minerals such as bentonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0005] Pyroclastic rocks coexist with attapulgite clay deposits. Pyroclast...

Problems solved by technology

[0005]Pyroclastic rocks coexist with attapulgite clay deposits, and pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits, and some attapulgite clay deposits The thickness of the pyroclastic rock layer in the upper layer of the mining area is as high as tens of meters. During the mining process of the attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. According to field investigations, every ton of attapulgite clay mining Rod stone clay produces more than 50 tons of pyroclastic rocks. Calculated at an annual output of 150,000 tons, the pyroclastic rocks produced are as high as 7.5 million tons. They have not been utilized for many years, and the entire mining area is re-accumulated everywhere. Pyroclastic rock mixture, causing serious waste of resources and economic losses
