Abstract

La presente invención se refiere a un proceso y una línea de producción para implementar el proceso, en donde el proceso es para producir placas de yeso (1) y comprende los siguientes pasos: alimentar una lechada de yeso (1g) que comprende estuco, agua y aditivos sobre un revestimiento inferior (21) dispuesto sobre un transportador (7) en movimiento, aplicar un revestimiento superior (22) sobre una superficie libre de la lechada de yeso para formar una estructura de tipo sándwich con un núcleo (1c) hecho de la lechada de yeso interpuesto entre los revestimientos superior e inferior (21, 22), fraguar por hidratación la lechada de yeso (1g) que forma el núcleo (1c) para formar una placa de yeso fraguada sobre el transportador, cortar la placa de yeso fraguada a las dimensiones deseadas para producir placas de yeso cortadas (1cp), secar las placas de yeso cortadas en una estación de secado (11) para producir las placas de yeso (1), en donde un flujo de fluido refrigerante (31) es aplicado sobre el revestimiento superior (22) para extraer calor de éste y evitar que la temperatura del núcleo (1c) aumente en más del 20%, preferentemente más del 10%, más preferentemente más del 1% desde el momento en que se alimenta la lechada de yeso (1g) sobre el revestimiento inferior (21) hasta que se corta la placa de yeso fraguada.The present invention relates to a process and a production line for implementing the process, wherein the process is to produce gypsum boards (1) and comprises the following steps: feeding a gypsum slurry (1g) comprising stucco, water and additives on a lower coating (21) arranged on a moving conveyor (7), applying an upper coating (22) on a free surface of the gypsum slurry to form a sandwich-type structure with a core (1c) made of the gypsum slurry interposed between the upper and lower coatings (21, 22), setting by hydration the gypsum slurry (1g) that forms the core (1c) to form a set gypsum board on the conveyor, cutting the gypsum board cured to the desired dimensions to produce cut gypsum boards (1cp), drying the cut gypsum boards in a drying station (11) to produce the gypsum boards (1), wherein a flow of cooling fluid (31) is applied on the upper coating (22) to extract heat from it and prevent the temperature of the core (1c) from increasing by more than 20%, preferably more than 10%, more preferably more than 1% from the moment the gypsum grout (1g) over the bottom liner (21) until the set gypsum board is cut.
