Study on Dry-ice Particle Jet Assisted Decontamination Technology

Dry-ice particle jet technology, which has the characteristics of no pollution, easy production and high impact, has been widely used in the cleaning of automobile, aviation, printing, electronics and nuclear industry. In this paper, a set of dry-ice jet spraying decontamination device was built. Two types of artificial pollutants, paint and oil contamination were smeared onto the workpieces. The effect of dry-ice particle jet spraying on the paint and the oil contamination was studied comprehensively. In addition, the wettability of the workpieces before and after dry-ice particle jet spraying was tested. The results of this study enrich the technology of industrial cleaning and promote the practical applications of the dry-ice particle jet spraying technology. (paper)
