Method for producing gypsum plaster through desulfurization gypsum
The invention relates to a method for producing gypsum plaster through desulfurization gypsum and belongs to the technical field of chemical building materials and solid waste comprehensive utilization. According to the method, the desulfurization gypsum is preprocessed, then dregs in the desulfurization gypsum are removed through a cyclone separator, then calcium sulfite is removed through high-temperature oxidization, and the desulfurization gypsum and glutinous rice are mixed, steamed, cooked, extruded, stretched and smashed into powder. The method has the advantages that the binding power of the gypsum plaster is improved, and stability of the gypsum plaster is enhanced; meanwhile, cost is reduced, and the environment is protected.
