Description

technical field

[0001] The invention belongs to the field of handicraft and jewelry production, in particular to artificial ivory produced by using desulfurized gypsum, an industrial solid waste produced by a power plant, and a manufacturing method thereof. Background technique

[0002] Desulfurization gypsum is a solid waste produced in the production process of thermal power plants, with an annual output of tens of millions of tons. Enterprises generally treat desulfurized gypsum in the form of stacking in the open air, which takes up a lot of land and pollutes the surrounding ecological environment on the other hand.

[0003] Over the years, people have realized that desulfurized gypsum is also an important resource, and have adopted a variety of technologies to comprehensively utilize it. At present, the main utilization methods include using desulfurized gypsum as raw material to produce construction gypsum powder, gypsum blocks, cement Retarders, etc., but most of the...
