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.
La présente divulgation concerne de manière générale des procédés de fabrication de panneaux en plâtre, tels que les panneaux muraux en gypse. Un aspect de l?invention concerne un procédé de fabrication d?un panneau de construction qui comprend la fourniture d?un panneau de construction humide en laissant une suspension de plâtre durcir entre des parements opposés, le panneau de construction humide ayant un c?ur de plâtre durci disposé entre les parements ; et la fourniture d?un agent tensioactif (tel qu?un tensioactif de sel d?ammonium quaternaire) sur au moins l?un des parements (par exemple, par l?application d?une composition contenant un agent tensioactif aqueux au parement) ; ensuite la conduite du panneau de construction humide vers un four de séchage, par exemple, par l?intermédiaire d?un ou plusieurs convoyeurs (par exemple, des rouleaux et/ou des courroies et/ou des rails) ; et le séchage du panneau de construction humide dans le four de séchage pour fournir le panneau de construction.
