【摘要】：目的研究汽化过氧化氢对不同材料物体表面受污染后的消毒效果,为对不同内环境的室内空间的消毒控制提供参考。方法采用5种材料制备染菌载体,定量杀灭枯草杆菌黑色变种芽孢和嗜热脂肪杆菌芽孢,观察过氧化氢气体在不同时间内对5种材质菌片的消毒效果。结果在30 m3密闭空间内用汽化过氧化氢对菌片进行10、20、30、40、60 min处理。以枯草杆菌黑色变种(ATCC 9372)芽孢为试验菌时,作用30 min对塑料载体上芽孢的杀灭对数值6.00;作用60 min对棉布、印刷纸、不锈钢和玻璃载体上芽孢的杀灭对数值均6.00。以嗜热脂肪杆菌(ATCC 7953)芽孢为试验菌时,作用30 min对不锈钢、玻璃和塑料载体上芽孢的杀灭对数值均6.00,作用60 min对棉布和印刷纸载体上芽孢的杀灭对数值均6.00。结论在设定的程序下,汽化过氧化氢对表面无孔无渗透材料的消毒效果显著好于表面多孔渗透性材料。
[Abstract]:Objective to study the disinfection effect of vaporized hydrogen peroxide on the surfaces of different materials, and to provide a reference for the disinfection control of indoor space in different internal environments. Methods five kinds of materials were used to prepare bacterium-contaminated carriers. To kill the spores of Bacillus subtilis var. Niger and Bacillus thermophilus quantitatively. To observe the disinfection effect of hydrogen peroxide gas on five kinds of bacteriological tablets in different time. Results in the closed space of 30 m ~ 3, 10 ~ (20) ~ (30) O ~ (40) was carried out with hydrogen peroxide vaporized. When the spores of Bacillus subtilis var. Niger ATCC9372) were treated for 60 min, the logarithmic value of killing spores on plastic carrier was 6.00 when the spores were treated for 30 min; The killing logarithm values of spores on cotton cloth, printing paper, stainless steel and glass carrier for 60 min were all 6.00.The spores of Adiposis thermophilus were used as test bacteria. The logarithmic value of killing spores on stainless steel, glass and plastic carrier for 30 min was 6.00. The logarithmic value of killing spores on cotton cloth and printing paper carrier for 60 min was 6.000.Conclusion under the set procedure. The sterilizing effect of vaporized hydrogen peroxide was better than that of porous porous materials.

【正文快照】： 过氧化氢是一类强效消毒剂,具有强氧化性,可使细胞通透性屏障受到破坏,其分解产物,如羟基和活性氧等自由基团可直接与微生物的蛋白和核酸发生反应〔1〕。传统的使用过氧化氢溶液消毒存在着很大的缺陷,杀菌效率较低,残留较多,具有一定腐蚀性,且对室内空间消毒限制较大。通过将
