摘　　要：目的:探讨超声清洗机在器械除锈方面的效果。方法:选择同等锈渍的生锈器械600件,随机分为实验组(305件)和对照组(295件)。将所有器械放入按1∶270比例配制好的多酶溶液里清洗有机污染物。实验组将生锈器械用不锈钢网篮盛装,放入水温为60℃、比例为1∶7配制好的除锈剂溶液的超声清洗机中,超声10 min后用软毛刷刷洗;对照组将器械放入与实验组相同的除锈剂溶液中,无恒温浸泡10 min后用软毛刷刷洗。观察并记录两种除锈方法除锈后的各项指标,并进行分析。结果:裸眼目测两组器械除锈合格率相比无差异;镜检法(5倍放大镜)实验组器械除锈合格率明显高于对照组,两组比较差异显著,有统计学意义(x2=38.9603,P<0.001);实验组器械的总体灵活度明显优于对照组,两组比较差异显著,有统计学意义(x2=13.7927,P<0.001)。结论:生锈器械在60℃恒温加超声清洗除锈效果明显,能提高器械的清洁质量及整体灵活度。Objective： To investigate the ultrasonic cleaning machine in the equipment derusting effect of. Methods： Rusty instrument as rust 600, were randomly divided into two groups, experimental group（n=305） and control group（n=295）. The first device in according to 1：270 proportion of organic pollutants in multi enzyme cleaning solution good, the experimental group will rust instrument containing stainless steel basket, in according to the proportion of 1：7（water temperature is 60 ℃） ultrasonic cleaning machine solution rust agent by ultrasound in 10 minutes, with a soft brush to wash; the control group will instrument in the water temperature in 60 ℃, solution rust agent 1：7 mixing ratio, non constant temperature for 10 minutes using a soft bristle brush. Observe and record the two rust rust indicators, and analysis. Results： The naked eye visual two groups of instruments derusting pass rate was not statistically significant（P0.05）;microscopy（5 times the magnifying glass） experimental group equipment derusting pass rate was significantly higher than that of the control group, there were significant difference between two groups（P0.001）; total flexibility in experimental group was significantly better than the instruments the control group, there were significant difference between two groups（P0.001）. Conclusion： The rusty instrument in a constant temperature of 60 ℃ plus ultrasonic cleaning descaling effect, improves the equipment clean quality and overall flexibility.
