How Gypsum Board Is Manufactured. Manufacturing gypsum board begins with the process of grinding and mixing the Gypsum with starch to help with bonding. Other trace ingredients might be added to the mix at this point depending on the nature of board required. Just enough water is added to create mixture of the right consistency.

FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.

A gypsum board includes a set gypsum core and front and rear paper facers adhered thereto. At least the front paper facer has substantially isotropic tensile strength, thereby providing the gypsum board with enhanced nail pull resistance. A process for manufacturing such gypsum board is further provided.

Gypsum Board Production Process 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.

Gypsum wallboard consists of a hardened gypsum containing core surfaced with paper or other fibrous material suitable to receive a coating such as paint. It is common to manufacture gypsum wallboard by placing an aqueous core slurry comprised predominantly of calcined gypsum between two sheets of paper thereby forming a sandwich structure.
