镁铝水滑石的制备及其涂层耐腐蚀性能的研究

目的 为了提高水性工业涂料的防腐蚀性能,常常会添加以含锌为主的防腐填料。然而,随着环保要求越来越高,以及欧盟限锌令的颁布,片层无锌镁铝水滑石(MgAl-LDHs)有望用于涂料中替代含锌填料。方法 采用共沉淀法合成无锌水滑石复合填料,并将其进行硅烷偶联剂表面改性,最后添加到丙烯酸树脂中,制备了水滑石防腐涂料。研究了不同制备工艺与水滑石结构之间的关系,以及不同添加量对涂料腐蚀性能的影响。结果 通过对比实验可以看出,当Mg∶Al(物质的量比)=2∶1,滴定终点pH值为11,能制备出相对完美的具有片层形貌、结晶度高、结构完整的镁铝水滑石;FTIR以及悬浮性测试表明,当MgAl-LDHs被KH570成功改性后,实现了表面亲水到疏水的转变,有效增加了与树脂的相容性;电化学考评发现,添加5%(质量分数)MgAl-LDHs的涂层240 h后防腐性能最好,塔菲尔电流密度最低为6.35 μA/cm²,容抗弧曲率半径最大;同时,耐盐雾试验证明,添加5%(质量分数)MgAl-LDHs涂层的耐腐蚀性能同样最佳,与电化学测试结果相匹配。结论 当MgAl-LDHs的添加量为5%(质量分数)时,涂层的防腐蚀性能最佳。MgAl-LDHs作为颜填料,能有效改善水性工业涂料防腐性能。

Earthquake-induced landslides: Distribution,motion and mechanisms

The objective of this paper is to clarify the factors that resulted in many landslides during the 2011 off the Pacific Coast of Tohoku Earthquake. The geology of the Tohoku district, the seismic motion of the main shock and the precipitation around the time of the earthquake are described. As one of the characteristic phenomena observed around Shirakawa city in Fukushima prefecture and the mid-eastern part of Tochigi prefecture, many of the slopes were characterized by a high distribution of sensitive volcanic cohesive soils. The estimated PGA and PGV around the areas were therefore larger, which might have promoted the softening of the sensitive soils.Although there had been little precipitation before the main shock, the landslides occurred mostly in the slopes containing the volcanic cohesive soils with higher water content. The influences of the ground water as well as other factors on the seismic slope stability are discussed in each of the following case studies. In order to clarify the mechanism of each landslide, the study focused on three typical landslides which occurred in the affected areas, i.e., the Hanokidaira, Okanouchi and Kami-kashiwazaki landslides. Detailed surveying with a laser profiler (LP) was carried out at the Hanokidaira and Okanouchi landslides to enable the topography of each slope before and after the main shock to be accurately grasped. Analytical examinations for the sliding mechanisms in each slope from an engineering point of view are made based on the numerical analyses with the actual soil properties observed in the laboratory tests. According to the results obtained from the cyclic direct and triaxial tests using the undisturbed specimens of the clayey loams sampled at the slip surfaces in each landslide, the shear strength can be reduced under cyclic loading and may eventually make the materials behave as those of high-mobility. Strength reduction is believed to be caused by the destruction of the clay particle structures originated from the sedimentation. Since the duration of the main shock exceeded three minutes, the slopes were subjected to the strong motion for a very long time. The sensitive cohesive soils resulted in a state with high mobility, which might have been the reason for the long distances traveled by the debris.
