臭氧被服消毒机杀菌效果的试验研究

为了解臭氧被服消毒机杀菌效果 ,采用载体定量杀菌试验方法 ,对肯格王被服消毒机杀菌效果进行了试验。结果 ,该机在空载的情况下 ,开机 4 0min ,对布片上金黄色葡萄球菌和大肠杆菌的杀灭率均达 99.90 %以上 ;开机 6 0min ,杀灭率均达 10 0 % ;开机 6 0min ,对布片上白色念珠菌的杀灭率达 99.90 %以上 ;开机 80min ,杀灭率达 10 0 %。在负载情况下 ,该机开机 6 0min ,对布片上金黄色葡萄球菌的杀灭率达 99.90 %以上 ;开机 12 0min ,对布片上黑曲霉菌的杀灭率达 99.90 %以上。该机开机 12 0min ,对棉絮上的自然细菌杀灭率达 94 .6 5 % ,对棉絮上的自然霉菌杀灭率达 94 .89%。在空载的情况下 ,2 5 %小牛血清对该机杀菌能力有轻度影响 ,5 0 %小牛血清有中度影响。结论 ,臭氧被服消毒机对布片上细菌繁殖体及霉菌均有良好的杀灭作用。

EXPERIMENTAL STUDY ON GERMICIDAL EFFICACY OF OZONE CLOTHING DISINFECTION MACHINE

In order to know the germicidal efficacy of ozone clothing disinfection machine, carrier quantitative germicidal test method was used to test the germicidal efficacy of Ken-Ge-Wang Clothing Machine. The results showed that under condition of vacant load, operation of the machine for 40 min killed more than 99.90% of both Staphylococcus aureus and Escherichia coli on cloth strips, operation for 60 min killed 100% of both of these two bacteria and more than 99.90% of Candida albicans on cloth strips, operation for 80 min killed 100% of the latter. Under loaded condition, operation for 60 min killed more than 99.90% of Staphylococcus aureus on cloth strips and operation for 120 min killed more than 99.90% of Aspergillus niger on cloth strips, 94.65% of natural bacteria on cotton wadding and 94.89% of natural fungi on cotton wadding. Under condition of vacant load, 25% calf serum had slight influence on its germicidal ability and 50% calf serum had moderate influence. The conclusion is that the ozone clothing disinfection machine has good killing effects on both vegetative form of bacteria and fungi on cloth strips.
