发明名称 Gypsum board comprising a mineral case
摘要 A continuous process for the production of gypsum board of variable yet predictable density, wherein a fibrous form of stucco produced from gypsum crystals or fibers is combined with standard calcined gypsum and formed into the board. The density of the resultant board varies inversely with the content of fibrous stucco. The process yields lightweight board suitable as standard wallboards and inorganic insulating boards.
