Abstract

Una lechada de yeso incluye sulfato de calcio hemihidratado, agua y sulfato de calcio dihidratado es recubierto con un recubrimiento hidrofílico dispersable. El recubrimiento es menos soluble que el sulfato de calcio hemihidratado, para retardar la exposicion del yeso en bruto a la lechada, previniendo una cristalizacion prematura y un endurecimiento temprano que esto conlleva. Otra modalidad es una lechada de yeso que incluye sulfato de calcio hemihidratado, un dispersante de policarboxilato, agua y sulfato de calcio dihidratado recubierto. En este caso el recubrimiento hidrofílico dispersable se selecciona para ser usado como un modificador para mejorar la habilidad del dispersante de fluidizar la lechada de yeso.
