METHODS FOR MANUFACTURING BUILDING BOARDS
The present disclosure relates generally to methods of manufacturing plasterboards, such as gypsum wallboards. One aspect of the disclosure is a method of manufacturing a building board that includes providing a wet building board by allowing a plaster slurry to set between opposing facings, the wet building board having a set plaster core disposed between the facings; and providing a surfactant (such as a quaternary ammonium salt surfactant) on at least one of the facings (e.g., by applying an aqueous surfactant-containing composition to the facing); then conducting the wet building board to a drying oven, for example, via one or more conveyers (e.g., rollers and/or belts and/or rails); and drying the wet building board in the drying oven to provide the building board.
