摘要
目的探讨医用清洗剂的金属腐蚀性,建立医用清洗剂金属腐蚀性试验方法。方法参照《消毒技术规范》(2002年版)进行金属腐蚀性试验。结果碱性清洗剂A对不锈钢、铜和铝的腐蚀程度强于碱性清洗剂B。13种多酶清洗剂中,对不锈钢为轻度和基本无腐蚀比例分别为7.69%和92.31%;对铜为中度、轻度和基本无腐蚀比例分别为15.38%、23.08%和61.54%;对碳钢为中度、轻度和基本无腐蚀比例分别为53.85%、30.77%和15.38%;对铝达到中度、轻度和基本无腐蚀的比例分别为7.69%、38.46%和53.85%。水垢去除剂、除锈剂和亮洁剂对铜、碳钢和铝的腐蚀程度均强于纯水,除碘剂对铜和铝的腐蚀程度强于纯水,润滑剂A对铜的腐蚀程度强于水,保湿剂A对铜的腐蚀程度强于水。结论不同医用清洗剂金属腐蚀性差异较大;医用清洗剂金属腐蚀性试验应丰富金属种类和完善对照组,并结合医用清洗剂p H值对金属腐蚀性能进行综合评价。
Objective To understand the corrosivities of medical detergents to metals and develop an evaluation methodology. Method Experimental procedure is in accordance with the Technical Standard of Disinfection（ 2002）. Results The corrosivities of alkaline detergent A to stainless steel,brass and aluminum are stronger than those of alkaline detergent B. In 13 multienzyme medical detergents,the rates of mild corrosive and non-corrosive actions to stainless steel are 7. 69% and 92. 31% respectively; the rates of moderate corrosive,mild corrosive and non-corrosive actions to brass are 15. 38%,23. 08% and 61. 54% respectively; the rates of moderate corrosive,mild corrosive and non-corrosive actions to carbon steel are 53. 85%,30. 77% and 15. 38% respectively; along with the rates of moderate corrosive,mild corrosive and non-corrosive actions to aluminum are 7. 69%,38. 46%and 53. 85% respectively. The corrosivities of scale remover,rust remover and brightening agent to brass,carbon steel and aluminum are stronger than those of pure water. The corrosivities of iodine remover to brass and aluminum are stronger than those of pure water. The corrosivities of lubricant A to brass is stronger than that of pure water. The corrosivities of humectant A to brass is stronger than that of pure water. Conclusions The variations of corrosivity for medical detergents are quite large. The authors recommend that there is a great need of more metals that used for medical device manufactures should take their parts in the above experiment. Besides,one should pay attention to the p H value of medical detergents,owing to it plays an important role in the evaluation of corrosiveness of such liquids.
