There are many types of gypsum for building, followed by model gypsum, gypsum, anhydrite, ground gypsum and ground gypsum. Next, how to control the calcination temperature of gypsum calcining equipment?
The raw material for gypsum production is mainly natural dihydrate gypsum, also known as soft gypsum or gypsum, which is calcium sulfate containing twin crystal water. Natural dihydrate gypsum can produce gypsum of various properties.
The main process of gypsum production is heating and grinding. Different properties of gypsum can be produced according to different heating temperatures and methods.
Building gypsum is a kind of gypsum that is calcined at 107C~170C with raw materials such as hydrogypsum, and then ground into white powder. Its main component is type b hemihydrate gypsum.

After hardening, the building has good thermal insulation and sound absorption and good fire resistance and moisture absorption; It is white in color and can be used for indoor painting construction, especially for making various types.
Building gypsum should not be used for outdoor works and high temperature works exceeding 65C.
In short, architectural gypsum can be used for indoor painting, making decorative products, gypsum porous products and gypsum boards.
If the content of impurities in the gypsum produced by calcining dihydrate gypsum with model gypsum is small, it is called model gypsum. Its performance is superior to that of building gypsum with high strength. It can be used to make models, carvings, decorative flowers, etc.
Put the hydrogypsum in a pressure cooker with gypsum, and steam it with l.3 atmospheric pressure (124C). Type a semi hydrated gypsum has high strength after grinding. This gypsum has high density and strength after hardening. Gypsum is suitable for plastering, decorative products, gypsum board with high strength requirements. The product can be used in high humidity environment after mixed with waterproof agent. The solution can also be added to prepare a binder for use.
