Caulking gypsum powder and preparation method therefor, and harmless treatment method for phosphogypsum |
| abstract |
Caulking gypsum powder and a harmless treatment method for phosphogypsum used in the aulking gypsum powder. The harmless treatment method for phosphogypsum comprises: regulating phosphogypsum to have neutrality or alkalescence; calcining; performing primary ageing; pulverizing; adding a curing agent into the pulverized phosphogypsum and mixing uniformly; and performing secondary ageing to obtain phosphogypsum power subjected to harmless treatment. The caulking gypsum powder comprises 100 parts by weight of phosphogypsum power subjected to harmless treatment, 10-30 parts by weight of coarse whiting, 5-20 parts by weight of white cement, 0.2-1.5 parts by weight of foaming agent, 1-5 parts by weight of retarder, 5-20 parts by weight of dispersible adhesive powder, and 5-25 parts by weight of water-retaining agent. |
