Frontiers of Chemical Science and Engineering 2016年第4期10卷 509-516页

Ltd. Tianjin 300457 China

Oil bleed is a serious problem in elastomeric thermal silicone conductive pads. The components of the oil bleed and the effect of the silicone chemical parameters on the amount ofoil bleed have been determined. The main components of oil bleeds are the uncrosslinked silicones in the cured resins, which include the unreacted silicone materials and the macromolecular substances produced by the hydrosilylation reaction. Cured resins with a high crosslinking density and a high molecular weight of vinyl silicone residues had a lower amount of oil bleed. In addition, a low Si-H content also reduced the amount ofoil bleed.

水库大坝稳定性影响着库区下游的安全,其安全稳定性极为重要,而周边环境(如地震)可能严重影响大坝的安全稳定。以研究12·2芒市地震对某水电站大坝影响为目的,通过对大坝及左右岸边坡地震前后水平位移进行监测,对比分析地震后当月的水平位移量与地震前1年无地震影响情况下正常每月的水平位移数据后,结果表明大部分监测点没有因为此次地震形变量出现突变超出该监测点前1年无地震影响情况下正常每月的形变量,所有监测点形变量均在该建筑物前1年无地震影响情况下正常每月的形变范围内,此次地震对该水电站大坝以及边坡影响较小,大坝及边坡安全稳定。
