Abstract
PROCEDIMIENTO DE PREPARACION DE YESO CALCINADO. SU FINALIDAD ES REBAJAR LA DEMANDA DE AGUA EN EL TRATAMIENTO DEL YESO CALCINADO SIN DISMINUIR LA RESISITENCIA DE LOS PRODUCTOS COLADOS CON EL. CONSISTE EN MEZCLAR AGUA, EN PROPORCION ENTRE EL 1 Y 10 POR 100, CON EL YESO CALCINADO, DEJAR QUE LA MEZCLA SE CURE Y SOMETERLA A TEMPERATURAS ELEVADAS; A CONTINUACION SE MUELE PARA INCREMENTAR EL AREA SUPERFICIAL DE SUS PARTICULAS, OBTENIENDOSE UN PRODUCTO ESTABLE AL ALMACENAMIENTO. LA ADICION DEL AGUA SE PUEDE HACER EN FORMA DE VAPOR. DE APLICACION PARA LA FABRICACION DE TABLEROS DE YESO PARA PAREDES.
