北京航空学院两栋五层装配化振动砖壁板宿舍楼,共9100平方米。这两栋振动砖壁板楼的外檐饰面均为水泥本色喷涂,墙面为绿色,窗套阳台为白色,面积共5000平方米,其中一栋的外檐喷涂是在去年严寒(-10℃～14℃)季节进行的。由于直接喷涂在外挂复合板的板面上(不抹底子灰),喷涂操作的气温为-3℃至-9℃,夜间架子上的最低温度为-14℃,喷涂层较薄,仅2毫米,又是直接喷在复合板水泥光面上,因此很容易受冻。在这样不利的情况下,怎样
Beijing Aviation Academy’s two five-storey vibration brick siding dormitory buildings total 9,100 square meters. The vibrated outer walls of the two vibrated brick sidings are cemented with natural colors, and the walls are green. The balcony of the window covers is white with a total area of 5,000 square meters. One of the exterior stencil sprayings was last winter (-10). °C ~ 14 °C) Seasonal. Because it is directly sprayed on the surface of the plug-in composite panel (without rubbing the base ash), the air temperature for the spraying operation is -3°C to -9°C, the minimum temperature at night stands is -14°C, and the sprayed layer is thin, only 2mm And it is directly sprayed on the smooth surface of the composite board cement, so it is easily frozen. In such a disadvantageous situation, how
