【摘要】：目的研究过氧化氢汽雾消毒机对不同性质载体上细菌杀灭效果。方法采用模拟现场消毒试验方法,对某过氧化氢汽雾消毒机杀灭不锈钢、玻璃、布、聚四氟乙烯等4种材料载体上细菌的杀灭效果进行观察。结果在实验舱内空气中过氧化氢浓度为358 mg/m3条件下作用120 min,对布片和玻片上金黄色葡萄球菌和大肠埃希菌杀灭率均达到99.9%以上;对不锈钢片和聚四氟乙烯片上金黄色葡萄球菌杀灭率为99.8%,对大肠埃希菌杀灭率达到99.9%以上。在过氧化氢相同浓度下现场消毒试验中,该过氧化氢汽雾消毒剂机除对玻璃台面自然菌消除对数值仅0.85之外,对不锈钢表面和塑胶地面上自然菌消除对数值均达到1.0以上。结论过氧化氢汽雾对不锈钢和塑料载体上细菌杀灭较布片和玻璃片难,而玻璃表面自然菌亦较难杀灭。
[Abstract]:Objective to study the germicidal effect of hydrogen peroxide steam mist disinfector on different carriers. Methods A hydrogen peroxide steam mist disinfector was used to kill stainless steel, glass cloth and stainless steel. The killing effect of bacteria on four kinds of materials such as PTFE was observed. Results under the condition of hydrogen peroxide concentration of 358 mg/m3 in the air of the experimental cabin, the bacteria were exposed for 120 min. The killing rates of Staphylococcus aureus and Escherichia coli on cloth and glass sheets were above 99.9%; The killing rates of Staphylococcus aureus and Escherichia coli on stainless steel and PTFE tablets were 99.8 and 99.9% respectively. The hydrogen peroxide steam mist disinfectant machine except for the glass Mesa natural bacteria elimination of the logarithmic value of only 0.85. The logarithm value of eliminating natural bacteria on stainless steel surface and plastic ground is more than 1.0. Conclusion hydrogen peroxide vapor mist is more difficult to kill bacteria on stainless steel and plastic carrier than cloth and glass. The glass surface of natural bacteria is also more difficult to kill.

【正文快照】： 过氧化氢在蒸汽或汽雾状态下具有较好的杀灭微生物的作用,加之其易分解、不残留,常用于室内空气终末消毒或消毒机内熏蒸消毒〔1-3〕。目前已出现活化过氧化氢体系,可以提高过氧化氢的稳定性及扩展其使用范围,为过氧化氢在化学毒剂分解及多孔介质表面消毒提供了更多选择〔2〕。
