Abstract: La presente invención proporciona una composición, una placa de yeso y su procedimiento de preparación, y el uso de ácido ascórbico como aditivo anticombado en una placa de yeso. Dicha placa de yeso comprende yeso fraguado preparado a partir de la composición; mientras que dicha composición comprende yeso hemi- hidratado, agua y un compuesto que comprende el grupo y no grupos carboxilato. El yeso fraguado preparado a partir de dicha composición muestra una mejor propiedad anticombado o de resistencia a la deformación. La placa de yeso de la presente invención se deforma difícilmente y tiene una estabilidad mayor incluso en la condición de alta humedad, así se mejora la calidad de la placa de yeso para responder a las exigencias del cliente.

Abstract: The present invention provides a gypsum composition, a gypsum board and their preparation method and the use of DHA as an anti-sagging additive in a gypsum product. Said gypsum board comprises set gypsum prepared from the composition; while said composition comprises gypsum, and an anti-deformation additive, wherein the anti-deformation additive comprises at least one selected from a group consisting of dehydroascorbic acid, dehydroascorbate and semidehydroascorbic acid. The set gypsum prepared from the said composition shows better anti-sagging or deformation resisting property. The gypsum product of the present invention is hardly distorted and has stronger stability even in the condition of high humidity, thus improve the quality of the gypsum product to meet the demands of the customer.
