Pure gypsum is a white-to-transparent mineral, though impurities can give the mineral a gray, brown, or pink coloration. Its chemical name is calcium sulfate dihydrate, and its chemical formula is CaSO4•2H2O. When gypsum is heated, it loses approximately three-quarters of its water and becomes hemihydrate gypsum.
Ground Gypsum FG200 is an extremely high purity, micronised gypsum grade, obtained from naturally occurring mineral. This product is used as a food additive (E516), food processing aid.It can be used as an additive or filler in proprietary formulations.
Apr 25, 2017 . Gypsum powder-based fertilizer effectively loosens hard subsoil or layers of clay in the garden. It penetrates the clay matrix and loosens its structure. It improves the composition of soil, prevents water runoff and soil erosion, facilitates water and air movement and root growth, converts salty soil into neutral.
To produce gypsum board, calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of paper on a board machine. As the board moves down a conveyer line, the calcium sulfate recrystallizes or rehydrates, reverting to its original rock state. The paper becomes chemically.
