脱硫石膏轻质底层粉刷砂浆施工应用技术研究

Research on Application Technology of Construction of Lightweight Gypsum Plaster from Flue Gas Desulphurization for Base Coating

以脱硫建筑石膏主要胶凝材料,配合轻骨料以及外加剂配制而成的脱硫石膏轻质底层粉刷砂浆,代替传统水泥砂浆或混合砂浆,兼具墙体的找平层和保温层,同时具有防火、吸声、调节空气湿度等功能。采用机械喷涂技术,可解决石膏砂浆的施工难度问题,且施工速度提高三倍。同时解决脱硫废渣的处置问题,符合循环经济和节能环保要求。

With desulphurization building gypsum as major gelled material, lightweight gypsum plaster from flue gas desulphurization for base coating made from lightweight aggregates and admixture is used to replace traditional cement mortar or composite mortar, which acts as both troweling course and insulation course of wall, and has fireproofing, sound absorption, air humidity regulation and other functions. Adopting the mechanical spraying technology can resolve the construction difficulty of gypsum mortar, and increase the construction speed by three times, In addition, it can solve the problem of disposal of waste residue of desulphurization, conforming to the requirements of recycling economy and energy saving and environmental protection.
