  • Preliminary study on desulpho-gypsum particleboard.

    Desulfo-gypsum originates from electric power plants that use flue-gas desulfurizer. This paper analyses the character of desulfo-gypsum and discusses the feasibility and process of manufacturing desulfo-gypsum particleboard. The results showed that desulfo-gypsum could be used for producing gypsum particleboard (GPB) and the properties of GPB were better than that using natural gypsum.
