| description | The present invention provides a mold-resistant gypsum panel that includes a core of an interlocking matrix of calcium sulfate dihydrate crystals, a facing material on at least one side of the panel and a salt of pyrithione dispersed through both the core and the facing material. Another aspect of the present invention is a method of making a mold-resistant gypsum product. A slurry of calcined gypsum, water and a water-soluble pyrithione salt is formed, then deposited on a sheet of facing material. The slurry on the facing material is shaped into a panel and maintained under conditions sufficient for the calcined gypsum to react with the water to form a core comprising an interlocking matrix of set gypsum crystals. Heating of the panel causes evaporation of the water that did riot react with the calcined gypsum.
La presente invencion proporciona un panel de yeso resistente al moho que incluye un nucleo de una matriz interconectada de cristales de dihidrato de sulfato de calcio, un material de cubierta en al menos un lado del panel y una sal de piritione dispersa tanto en el nucleo como el material de cubierta. Otro aspecto de la presente invencion es un metodo para hacer un producto de yeso resistente al moho. Un lechado de yeso calcinado, agua y una sal de piritione soluble en agua, depositado despues sobre una hoja del material de cubierta. El lechado en el material de cubierta adquiere la forma de un panel y se mantiene bajo condiciones suficientes para que el yeso calcinado reaccione con el agua para formar un nucleo que comprende una matriz interconectada de cristales de yeso fraguados. Calentar el panel ocasiona la evaporacion del agua que no reacciono con el yeso calcinado. |
