摘要/Abstract

摘要： 压制去污技术是有效处置核事故污染的技术手段之一。去污材料与其相应的作业机械构成了去污技术的组成部分,目前去污剂喷洒作业过程中常存在去污材料混合不均匀、膜体不易剥离等问题。为此,开发了一款主动旋转混合方式的动态混合器,解决去污剂混合不均等问题。为验证动态混合器混合效果,搭建了反应型压制去污剂动态混合试验系统,开展了去污剂混合均匀性、成膜时间、可剥离性、膜体微观形态、拉伸强度等试验研究。试验结果表明,新型动态混合器性能较好,材料混合均匀,材料膜体力学性能和可剥离性均满足应用要求,研究结果可为去污喷洒车改进设计提供重要的技术支撑。

Abstract: Background: As one of the important techniques, coating decontamination technology can effectively deal with radioactive residues of nuclear accident. Decontaminating materials and its operating machines are important parts of coating decontamination technology. There are, however, some problems in the process of spraying decontaminating materials, such as the decontaminant inhomogeneouslly mixed and hard-to-peel the coating. Purpose: The well designed dynamic mixer can solve the issue of the decontaminant inhomogeneous-mixing. Methods: A new dynamic mixer is developed. The testing system of the dynamic hybrid characteristics of the decontaminating materials is set up to verify the rationality of the designed dynamic mixer. The tests of the mixing uniformity of the decontaminant, the film formation time, the stripping characteristics of the decontaminant, the microstructure and tensile strength of the coating are carried out. Results: The decontaminant material is evenly mixed. The mechanical property of the material film and the stripping characteristics meet the application requirements. Conclusions: The new designed dynamic mixer has good performance. The results of the study could provide important technical support for the improvement design of the decontamination vehicle.

Key words: coating decontaminant, dynamic mixer, testing system, mixing uniformity
