以电镜观测，Ｘ射线衍射谱图分析，结合传统性能试验手段，对氯氧镁复合材料的耐水性进行研究，通过掺加改性剂试验，优选出Ｋ３（ＸＹ６）为最佳改性剂，其浸水三个月的软化系数保留在０．９４。同时利用现代测试技术，对其改性机理进行了探索。
The water resistance of the magnesium oxychloride composites was studied by electron microscopy and X-ray diffraction (XRD) spectroscopy. The best modifier K3 (XY6) was selected by adding the modifier. Its softening coefficient of three months immersion remained at 0.94. At the same time using modern testing technology, its modification mechanism was explored.
