水解石膏粉和水解石膏空心隔墙板(简称空心石膏板)是利用木材水解生产酒精过程中排出的石膏废渣研制成功的新型建筑材料。水解石膏粉可用于建筑施工的抹灰灰泥、石膏胶泥、石膏腻子和制造石膏板等,该项制品经物理、化学性能测试,其各项技术指标均达到了国家建筑石膏质量标准。空心石膏板可用于工业和民用建筑的内隔墙板,该项制品经物理力学性能试验,均达到了国内其他种类化学石膏制品的质量标准。
Hydrolyzed gypsum powder and hydrolyzed gypsum hollow partition wall board (referred to as hollow gypsum board) is a new type of building material that has been successfully developed through the use of wood hydrolysis to produce gypsum waste residue discharged during the production of alcohol. Hydrolyzed gypsum powder can be used for plastering plaster, gypsum plaster, plaster putty and gypsum board in construction. The product has been tested for physical and chemical properties. Its technical indexes have all met the national building gypsum quality standards. Hollow gypsum board can be used in the internal partition board of industrial and civil buildings. The physical and mechanical properties of the product have reached the quality standards of other types of chemical gypsum products in China.
