摘要: 为了实现介质表面放射性污染粉尘的快速去污,提出一种应用热熔压敏卷材清除表面污染粉尘的方法。通过对热熔压敏胶黏剂与卷材基布的筛选,设计和制备了一种热熔压敏去污卷材,分别采用过100目、20目标准筛的粉尘模拟核爆落下灰和放射性污染颗粒物,对热熔压敏去污卷材进行模拟去污试验。试验结果显示,所制备的热熔压敏卷材在140 ℃、施加25 kPa以上压强时,对不锈钢表面的模拟放射性污染粉尘和颗粒物的单次去污率均在80%以上,最高达到92.5%。验证了热熔压敏卷材对表面放射性污染粉尘的去污效果,可为工程应用提供参考。

Abstract: This study aims to develop a new method for quickly removing surface radioactive contamination with hot-melt pressure sensitive coil material. The hot-melt pressure sensitive coil was designed and prepared by screening hot-melt pressure sensitive adhesives and substrates. Simulated decontamination tests with the coil material were conducted to decontaminate dusts prepared with 100-mesh and 20-mesh standard sieves for simulating nuclear explosion fallout and radioactive contaminated particles, respectively. The single-time decontamination efficiencies for simulated fallout and contaminated particles are both above 80% at conditions of 25 kPa pressure and 140 ℃ temperature, a maximum single-time decontamination efficiency is 92.5%. These results validated its decontamination effect of the prepared hot-melt pressure sensitive coil material for removing surface nuclear explosion fallout and may provide useful information for its practical application.

Key words: hot-melt pressure sensitive adhesive, radioactive contamination, radioactive dust, decontamination coil material, decontamination efficiency
