Embodiment 1
[0029] A phosphogypsum-based steel wire grid composite wallboard, comprising the following components by weight on a dry basis: 70 parts of phosphogypsum powder, 15 parts of mineral powder, 2 parts of active mineral powder, 5 parts of cement, 8 parts of quicklime, and a foaming agent 1 part, 0.5 part of admixture, 3 parts of steel wire grid, 0.5 part of glass fiber mesh cloth.
[0030] When preparing, first place the steel wire mesh frame in the mold for use, then weigh phosphogypsum powder, mineral powder, active mineral powder, cement, quicklime and foaming agent and pour them into a mixer to stir and mix to obtain the mixture A. Add water with a material-to-water ratio of 0.45-0.55 into the admixture to obtain an admixture solution, add the admixture solution to mixture A and stir for 1 min with a mixer at a speed of 200 rpm to form a mixed slurry; put the mixed slurry in the mold It is poured and formed at a temperature of 40-48°C, sent to a curing room at 45°C, and left t...
