Method for preparing air-entrapped hollow brick by utilizing stove exhaust gas
The invention discloses a method for preparing an air-entrapped hollow brick by utilizing stove exhaust gas. The method for preparing the air-entrapped hollow brick by utilizing the stove exhaust gas comprises the following steps: 1) mixing 11-13 parts of fluorite slag, 5-7 parts of clay, 8-10 parts of coal gangue and 4-6 parts of sodium fluosilicate, crushing to obtain a crushed material with the particle size of 200-300 meshes, weighing and mixing 5-10 parts of phosphogypsum, 2-4 parts of aluminium powder and 20-30 parts of cement with the crushed material, and carrying out fine grinding. The method for preparing the air-entrapped hollow brick by utilizing the stove exhaust gas has the advantages that usage amount of fluorite slag is high, the problem that the stove exhaust gas is polluted, energy conservation and environmental protection are realized, the environmental pollution problem caused by stockpiling and treatment of the fluorite slag can be alleviated, and a new raw material source is provided for the hollow brick.
