    摘要： 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.

    摘要翻译： 本发明提供石膏组合物，石膏板及其制备方法以及在石膏制品中使用DHA作为防流挂添加剂。 所述石膏板包括由组合物制备的集石膏; 而所述组合物包含石膏和抗变形添加剂，其中所述抗变形添加剂包含选自脱氢抗坏血酸，脱氢抗坏血酸和半抗坏血酸的至少一种。 由所述组合物制备的凝固石膏显示更好的抗流挂或抗变形性能。 本发明的石膏制品几乎不变形，即使在高湿度的情况下也具有更强的稳定性，因此提高了石膏制品的质量以满足顾客的要求。

    摘要： A self-drilling anchor including a screw and an anchor body configured to receive a shank of the screw, the anchor body including: a flange at an end oriented toward a head of the screw, a threaded portion, a deformable expansion portion between the flange and the threaded portion, and a rotation locking mechanism preventing rotation of the anchor body relative to the wall. The threaded portion is configured to engage with the screw thread and advance in a direction of the flange, by deforming the expansion portion, when the screw is screwed into the threaded portion. The anchor body further includes a piercing element at the opposite end from the flange, the anchor including a fastening mechanism between the screw and the anchor body, the fastening mechanism being detachable by a torque, applied between the screw and the anchor body, equal to or greater than a predetermined torque.

    摘要： The present invention provides a composition, a gypsum board and their preparation method and the use of ascorbic acid as an anti-sagging additive in a gypsum board. Said gypsum board comprises set gypsum prepared from the composition; while said composition comprises hemi-hydrate gypsum, water and a compound comprising group and no carboxylate groups. The set gypsum prepared from the said composition shows better anti-sagging or deformation resisting property. The gypsum board 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 board to meet the demands of the customer.
