soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In
Plasterboard Production - Knauf
How Plasterboard is Made. Knauf gypsum plasterboard is manufactured in a continuous production process. A gypsum slurry is made up from stucco, or plaster of Paris, water and other additives, in a continuous mixer. This slurry spreads, in a uniform stream, from multiple outlet hoses onto a moving sheet of paper.
Gypsum Plasterboard: Manufacture & Additives - Greenspec
Plasterboard production 'Stucco' is produced by removing around 75% of the water from the gypsum through heating using natural gas to a temperature of over 150'C. This process of 'calcination' changes calcium sulphate from its dihydrate state (gypsum) to its hemihydrate state.
