氧泡泡过碳酸钠消毒剂的消毒杀菌效果评价

Evaluation of oxyaction sodium percarbonate disinfectant

为了解氧泡泡过碳酸钠消毒剂的产品性能,对其进行了理化指标、毒性毒理、产品稳定性、消毒杀菌效果等多方面评价。结果表明,氧泡泡过碳酸钠消毒剂的理化指标符合相关规范的标准。在规定测试条件下,对大肠杆菌、金黄色葡萄球菌及铜绿假单胞菌的平均杀灭对数值均大于等于5.00,对白色念珠菌平均杀灭对数值大于等于4.00,对黑曲霉菌平均杀灭对数值大于等于4.00,20 m2密闭房间空气中自然菌的消亡率3次实验结果均大于等于90%,人工染菌于织物表面样本上大肠杆菌的平均杀灭对数值大于等于3.0,对物体表面自然菌的平均杀灭对数值大于等于1.0,对医疗污水粪大肠菌群的杀灭效果符合相关标准要求。腐蚀性测试表明,对碳钢属轻微腐蚀,对不锈钢、铝、铜基本无腐蚀。稳定性测试表明,放置于54℃恒温恒湿箱存储14天过碳酸钠含量下降率为5.8%。

To understand the performance of oxyaction sodium percarbonate disinfectant,the physicochemical index,toxicity and toxicology,stability,disinfection efficacy and other properties thereof were evaluated.The results showed that the physicochemical properties accorded with corresponding industry standards.Disinfection test showed that under specified conditions,the average killing log values were≥5.00 for Escherichia coli,Staphylococcus aureus and Pseudomonas aeruginosa,≥4.00 for Candida albicans,and≥4.00 for Aspergillus niger.The natural decay rates of natural bacteria from three repetitive tests conducted in a 20 m2 sealed room were all≥90%.The average killing log values were≥3.0 for Escherichia coli on cloth,and≥1.0 for natural bacteria on table surface.The disinfection efficacy against fecal coliform in medical waster water met the industry standard.Meanwhile,the product was only mildly corrosive to carbon steel,and not corrosive to aluminum,copper or stainless steel.In addition,the product showed only 5.8%decrease of sodium percarbonate after 14 days in a constant temperature and humidity chamber at 54℃.
