摘要
为了解溴氯海因消毒片的杀菌效果,进行了载体定量杀菌试验与腐蚀性试验。结果,有效氯溴含量为 1200mg/L(有效溴含量为 632mg/L),作用 90min,对布片上枯草杆菌黑色变种芽孢的杀灭率达 99. 90%;以有效氯溴含量为 90mg/L(有效溴含量为 47mg/L),分别作用 8min和 6min,对布片上金黄色葡萄球菌和大肠杆菌的杀灭率均达 99. 90%;以有效氯溴含量为 1200mg/L(有效溴含量为 632mg/L)作用 90min,可有效破坏HBsAg的抗原性。有机物对其杀菌作用有影响。该消毒片存放于 54℃ 14d,有效氯溴含量下降率为 0. 96%。用含有效氯溴 1200mg/L水溶液浸泡 72h,对不锈钢无腐蚀性,对铜和铝有中度腐蚀,对碳钢重度腐蚀。
In order to know the germicidal efficacy of the Bromochlorohydantoin Disinfection Tablet, carrier quantitative germicidal test and corrosiveness test were carried out. Results: The killing rate of spores of Bacillus subtilis var. niger on cloth strip exposed to the solution containing available chlorine and bromine 1200 mg/L (available bromine content was 632 mg/L) for 90 min was 99.90% and that of Staphylococcus aureus and Escherichia coli on cloth strips exposed to the solution containing available chlorine and bromine 90 mg/L (available bromine content was 47 mg/L) for 8 min and 6 min respectively attained 99.90%. The solution containing available chlorine and bromine 1200 mg/L (the available bromine content was 632 mg/L)with a 90 min contact time could destroy effectively the antigenicity of HBsAg. Organic substance had influence on its germicidal action. After the Disinfection Tablet was stored at 54℃ for 14 days, its available chlorine and bromine content decreased by 0.96%. Immersion in the water solution containing available chlorine and bromine 1200 mg/L for 72 h was not corrosive to stainless steel, moderately corrosive to copper and aluminum and heavily corrosive to carbon steel.
