Problems solved by technology

Ordinary sintered bricks have the disadvantages of heavy weight, small size, high production energy consumption, and low construction efficiency. Using sintered porous bricks and sintered hollow bricks instead of sintered ordinary bricks can reduce the weight of buildings by about 30% and save clay by 20% to 30%. , save fuel by 10% to 20%, and increase the efficiency of wal

Abstract

The invention relates to the technical field of fired perforated brick preparation and concretely relates to an electrolytic manganese residue fired perforated brick and a preparation method thereof. The electrolytic manganese residue fired perforated brick is prepared from 45-65 parts by weight of modified electrolytic manganese residues, 15-25 parts by weight of clay, 10-15 parts by weight of fly ash, 15-25 parts by weight of coal, 10-20 parts by weight of sugar refinery residues, 15-25 parts by weight of black talc, 3-8 parts by weight of polyvinyl alcohol, 3-8 parts by weight of sodium carboxymethylcellulose, 2-5 parts by weight of crosslinked polyacrylic acid resin and a proper amount of water. The invention provides a preparation method of the electrolytic manganese residue fired perforated brick. The brick solves the problem of environmental pollution-caused by electrolytic manganese residue accumulation. The perforated brick has the characteristics of high finished product qualification rate, good air permeability and low water absorbency.

Description

【Technical field】 [0001] The invention relates to the technical field of sintered brick preparation technology, in particular to an electrolytic manganese slag sintered porous brick and a preparation method thereof. 【Background technique】 [0002] Electrolytic manganese slag is composed of manganese carbonate-based rhodochrosite, which is ground and reacted with sulfuric acid to obtain a manganese sulfate solution. After extracting metal manganese, the weakly acidic industrial waste has a fine particle size, a moisture content as high as 16%-40%, and a viscous Thick and easy to form a block and so on. Manganese metal is one of the important strategic resources in the national economy. my country is a big producer of electrolytic manganese, but at the same time, as a typical hydrometallurgical electrolytic manganese industry, while promoting economic development, it also brings serious problems such as stacking of electrolytic manganese slag and pollution. environmental probl...
