Technical Field
The embodiment of the invention relates to the technical field of building materials, in particular to a boron mud hollow brick and a preparation method thereof.
Background
At present, borax is mainly produced by using boron-magnesium-stone mineral and boron-magnesium-iron mineral in Liaoning province, and the grade (B) of the borax 2 O 3 Content) is 8-15% mostly, and the other components are gangue minerals. In the borax production process, some gangue minerals and boron ores are roasted together, and after sand is pulverized and participates in chemical reaction, the residue left is called boron mud.
The boric sludge contains various alkaline oxides, the pH value is 8-11, the boric sludge is alkaline, the part where the boric sludge is discharged is not grass, and the alkali liquor can be dissolved into underground water, so that the drinking water around the part is polluted. Because the boric sludge particles are fine, the boric sludge can be scattered along with wind after losing moisture, and the atmospheric environment is polluted. Boric sludge has become a significant source of pollution.
Therefore, the resource utilization of the boron mud is the key for the sustainable development of the boron industry and the green development of the economic ecological cycle.
