【摘要】：正 现有的石膏装饰板极易受潮,受潮后吸水率可达40%～50%,断裂荷载大大降低,易翘曲变形.同时吸水后引起表面发花,甚至霉变,严重影响装饰效果,限制了石膏装饰板的推广应用.针对上述问题,我们进行了复合石膏板的研究并取得了预期的效果.二、原材料的选用及配方设计1.复合装饰石膏板的主要原料β半水石膏:湖北应城产,细度120目.玻璃纤维:南京产,工业废丝.膨胀珍珠岩:信阳产,表观密度≤80kg/m~3.
[Abstract]:The existing gypsum decorative board is easy to be dampened, the water absorption rate can reach 40% and 50%, the fracture load is greatly reduced, and warping is easy. At the same time, water absorption caused surface flower, even mildew, which seriously affected the decorative effect and limited the popularization and application of gypsum decorative board. In view of the above problems, we studied the composite plasterboard and achieved the desired results. Second, the selection of raw materials and formula design 1. Composite decorative plasterboard main raw materials 尾-hemihydrate gypsum: Hubei should be produced, fineness 120 mesh. Glass fiber: Nanjing, industrial waste silk. Expanded perlite: Xinyang, apparent density 鈮，
