摘　　要：制备了高分子可剥离去污膜液 ,确定了涂膜液中各组分最佳含量 ,对固体表面核素的去除研究结果表明 :在金属表面采用涂膜电解去污、非金属光滑固体表面采用直接涂膜去污、非金属粗糙固体表面采用涂膜超声去污工艺 ,其去污率均可达 99%以上 ,优于其他方法。Polymer strippable coatings for deconta mination was prepared ,and liquid membrane components’ con tents were defined .It was for the first time to investigate this systematically for the contamination the uranium caused on the solid surface of the equipment in nuclear industry.Results indicated that the decontamination effi ciency was more than 99% when coating and electrolysis method was used on the metal surface ,direct coating method was used on the nonmetal smooth solid surface and coating and ultras on icmethod used on the nonmetal rough solid surface.The methodsolved the problem that the decontamination efficiency was low by others methods.It compares favorably to other methods.
