Characteristic 1)Desulfurization Gypsum can also be written as FGD(Flying Gypsum Division)according to its forming process.

2)Desulfuriztion Gypsum is one of the chemical Gypsum.The chemical Gypsum is wastes from human production and environment protection activities.3)Equation formula:The formation of Desulfurization Gypsum actually needs a series of complicated chemical reactivities.The theory of the forming is mainly through the following equation formula:SO2+H2O

4)H.S code:3824400000

5)Desulfuriztion Gypsum is a kind of industrial outgrowth gypsum after the process is :dust-removaled sulfur containing gas is transmitted to the absorption container.then spray the slurry which formed by power lismstone or limstone .CaSO3 is produced via reaction between the slurry and SO2 in the gas.the caso3 is oxidize to CaSO4 via introducing a lot of air.the gypsum in suspension from from the absorption container undergoes condestion and dehydration then the final outcome is high proportion of gypsum  damp loose particles whoese moisture content is 10%-20%

Purpose

As a kind of industrial ourgrowth gypsum.it has some characteristics of natural gypsum and recycled gypsum.some resource limited countries have produced chemical gypsum to replace natural anhydrite gypsum.some plasterdord factories are usin g desulfuriztion gypsum as an additive.in addition,Desulfuriztion gypsum can be also used as additive for cement manufacturing to shorten the solidification time.
