Partition wall strip plate prepared from red mud and preparation method thereof

Abstract

The invention relates to a partition wall strip plate and in particular relates to a partition wall strip plate prepared from red mud and a preparation method thereof. The partition wall strip plate is prepared from the following raw materials in percentage by weight: 55 percent to 80 percent of the red mud, 10 percent to 30 percent of aggregate and 5 percent to 25 percent of additive; the additive is prepared from the following raw materials in parts by weight: 65 to 80 parts of silicate, 5 to 10 parts of borate, 5 to 10 parts of sulfate, 1 to 5 parts of phosphate, 1 to 3 parts of hydroxide,3 to 5 parts of halogen salt and 1 to 5 parts of lignosulfonate. According to the partition wall strip plate prepared by the invention, grain surface chemical modification, combination of substances between grains, generation of gel substances and formation of various crystal structure substances can be directly or indirectly carried out on the red mud under the action of the additive; the prepared partition wall strip plate has the characteristics of high anti-bending self-weight times, high compression strength, high softening coefficient and the like; the invention further provides a preparation method of the partition wall strip plate and the preparation method is low in cost and environmentally friendly.

Description

technical field [0001] The invention relates to a partition wall strip, in particular to a partition wall strip prepared from red mud and a preparation method thereof. Background technique [0002] Because the chemical alkali combined with red mud is difficult to remove and the content is large, and it also contains fluorine, aluminum and other impurities, it has been difficult to carry out harmless utilization of red mud. Experts from all over the world have conducted a lot of scientific research on the comprehensive utilization of red mud, but such research has made little progress. Therefore, the treatment and comprehensive utilization of red mud residue has become a worldwide problem. [0003] However, with the development of the aluminum industry, the amount of red mud discharged from the production of alumina is also increasing, and a series of problems caused by stockpiling and disposal will be It has caused serious environmental problems. [0004] Most of the alum...

Problems solved by technology

Sewage with high alkalinity seeps into the ground or enters the surface water, which increases the pH value of the water body, so that it exceeds the corresponding national standard. At the same time, because the pH value often affects the toxicity of the compounds in the water, it will also cause more serious water pollution.
