Abstract
The invention discloses alpha-gypsum and a production method thereof. The production method comprises the following steps: mixing desulfurization gypsum or citric acid gypsum and water according to a specified ratio, pulping, thereby obtaining slurry; carrying out a hydrothermal reaction on the slurry; dehydrating and drying on the reactants, thereby obtaining the finished product, namely high-strength super-hard alpha-gypsum. The produced high-strength super-hard alpha-gypsum can be made into multiple high-grade gypsum molds or high-grade buildings and decorative materials and has the advantages of high liquidity, high simulation ability, high strength, smooth surface and the like.
Description
technical field [0001] The invention relates to α-gypsum and a production method thereof, in particular to a high-strength superhard α-gypsum and a production method thereof. technical background [0002] At present, my country has become the country with the largest emission of sulfur dioxide, most of which are emitted by thermal power plants. my country's coal-fired power plants account for more than half of the country's total sulfur dioxide emissions, making them major emitters of sulfur dioxide. Limestone / lime wet flue gas desulfurization method is currently the most important method for removing sulfur dioxide. This method produces a large amount of solid residue mainly composed of calcium sulfite. Because calcium sulfite is unstable, it cannot It is easily oxidized to calcium sulfate, and its crystal form is similar to gypsum, that is, flue gas desulfurization gypsum. In power plants equipped with desulfurization devices, flue gas desulfurization gypsum is increasin...
