摘要
采用溶液包覆法,分别以硬脂酸、石蜡和聚偏二氯乙烯为包覆材料,探究了包覆材料与氢化铈的结合方式、包覆膜结构以及包覆后氢化铈室温时的防水性能和抗氧化性能.结果表明,当包覆量为4%(包覆材料与氢化铈的质量百分比)及以上时,采用硬脂酸和石蜡为包覆材料的氢化铈安定性处理效果较好,包覆后的氢化铈粉末均具有至少15d防水和抗氧化能力,包覆膜与氢化铈之间以物理方式结合;而采用聚偏二氯乙烯为包覆材料时,氢化铈表面基本不能形成包覆膜,包覆效果差,无法对氢化铈起到安定性处理作用.

Abstract:
The cerium hydride was surface coated with stearic acid,paraffin wax and poly-vinylidene chloride using the solution coating method.The combination mode of coating material with cerium hydride,the coating layer structure as well as the waterproofing and antioxidation properties of cerium hydride at room temperature were investigated.The results show that when the amount of coating materials is 4% or more (the quality percentage of cerium hydride),the stability of cerium hydride coated with stearic acid and paraffin wax is good,the coated cerium hydride powder has at least 15 days waterproof and oxidation resistance.The coating layer is physically bonded with cerium hydride.When polyvinylidene chloride is used as coating material,the coating layer was hardly formed on the surface of cerium hydride,and it can't stabilize cerium hydride.
