沈阳市第一建筑工程公司大型垟板厂外垟板生产线已于今年六月份投入试生产,该线设计年产量为24300立米,工作节拍为21分钟,品种为单一材料的坒板。目前,因原材料关系,试生产玻玏棉复合外垟板(见右图),水泥混凝土标号200~#,板厚220毫米,内隔50～60毫米厚的玻玏棉,坒板总热阻值为0.808米~2。 Shenyang First Construction Engineering Co., Ltd. The large raft factory external raft production line has been put into trial production in June this year. The designed output of the line is 24,300 m3, and the working cycle is 21 minutes. The type is a single material fascia board. At present, due to the raw material relationship, try to produce glass-wool-cotton composite external crucibles (see the figure on the right), 200-# cement concrete, 220-mm-thick plate thickness, and 40-60 mm thick glass-ramon cotton with total thermal resistance. The value is 0.808 meters~2.
