摘　　要：针对目前玻化微珠保温砂浆导热系数偏高而无法突破的技术瓶颈,研究了一项玻化微珠保温砂浆发泡技术,该技术能降低保温砂浆终凝后的导热系数,并使其强度只有小幅衰减,满足使用要求。改进喷涂发泡机械,使机械喷漆玻化微珠保温砂浆能够得到广泛应用。针对改进后的喷涂发泡机械,提出了一套施工工艺流程,实践证明其在施工操作中简单可行,施工效率高。Most insulation mortar has relative higher thermal conductivity and is hard to break through. To solve this problem, a new foaming technology for vitrified microsphere insulation mortar is discussed. This new technology can reduce the thermal conductivity largely however slightly decrease the strength to satisfy the usage requirement. A spray machine of mortar foaming is also developed for construction. The use of spray technology can increase the strength of the mortar final setting and widen the application field. A construction process for the spray foaming machine is put forward and confirmed by practice, The spray foaming machine is easy to operate and has a higher efficiency.
