热熔压敏卷材清除放射性污染粉尘的试验研究

Abstract

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
