Abstract
Description
technical field
[0001] The invention relates to the field of industrial gypsum reuse, in particular to an industrial synthetic sulfur gypsum and a preparation method thereof. Background technique
[0002] Natural gypsum is an essential raw material for cement production, and its main components are composed of calcium sulfate and crystal water. Its main indicators are about 30% sulfur trioxide and about 10% crystal water. And the existing industrial waste residue, i.e. fluorine gypsum sulfur trioxide has 53% and no water of crystallization. Titanium gypsum has about 34% sulfur trioxide and about 18% crystal water. The external level is 35% on average. If the gypsum used in cement production has no crystal water, it will affect the performance of cement, and if the external water exceeds 10%, it will not be able to produce normally. Contents of the invention
[0003] In order to solve the above technical problems, the present invention proposes an industrial synthetic s...
