acidified pyroclastic rock

Abstract

The invention discloses an acidized pyroclastic rock. The key points of the technical scheme are as follows: the acidized pyroclastic rock ingredients comprise pyroclastic rock, attapulgite clay, magnesium oxide, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate, and are input into a mill to be ground, and the ground powder is the acidized pyroclastic rock; the production method of the acidized pyroclastic rock adopts the steps of acidizing firstly and then compounding, so that sulfuric acid is prevented from chemically reacting with instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate, the pH value of the pyroclastic rock subjected to acidification is controlled to be 5.5-7.0, the utilization rate of the pyroclastic rock can be increased, good economic benefit, environment benefit and social benefit are achieved, the wastes are changed into wealth, the acidized pyroclastic rock is suitable for producing environment materials, building materials, foaming agents and fire products.

Description

Technical field [0001] The invention relates to acidification treatment, in particular to an acidified pyroclastic rock. Background technique [0002] There are also volcanic clastic rocks that coexist with attapulgite clay mines. Most of the volcanic clastic rocks are on the upper layer of the attapulgite clay mine. In some attapulgite clay mines, the thickness of the upper layer of the pyroclastic rock is as high as tens of meters. During the mining process of attapulgite clay, the volcanic clastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. According to field investigations, every 1 ton of attapulgite clay produced will produce more than 30 tons of pyroclastic rock. Based on the annual output of 150,000 tons, the produced pyroclastic rock is as high as 4.5 million tons, which has not been used for many years. The entire mining area is full of re-stacked pyroclastic mixtures, causing serious resource waste and economic losses . [0003] Py...

[0002] Pyroclastic rocks coexist with attapulgite clay deposits. Pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits. In some attapulgite clay deposits, the thickness of pyroclastic rock layers in the upper layer is as high as tens of meters. During the mining of attapulgite clay, pyroclastic rocks in the upper layer of the attapulgite clay mining area are discarded as waste. According to field investigations, more than 30 tons of pyroclastic rocks are produced for every ton of attapulgite clay mined. Calculated at an annual output of 150,000 tons, the generated pyroclastic rocks are as high as 4.5 million tons, which have not been utilized for many years. The entire mining area is full of re-accumulated pyroclastic rock mixtures, causing serious waste of resources and economic losses.
