新型氯-醛发烟熏蒸消毒剂效果研究

Study on The Efficacy of a New Chlorine Glutaraldehyde Fumigation Disinfectant

以二氯异氰脲酸钠和戊二醛为主要原料制备的氯-醛发烟熏蒸消毒剂具有操作便捷,安全,不需明火点燃等优势。研究发烟及燃烧效果发现,当戊二醛和二氯异氰脲酸钠质量比为1∶4时为最优配比。在养殖场测定其熏蒸消毒效果,消毒前后经过定位取样及平板沉降法取样培养,结果显示,养殖圈舍内物表综合杀菌率达到99%以上,圈舍内空气综合杀菌率达到98%,孵化室内物表综合杀菌率达到99.99%以上。实验表明,该氯-醛发烟熏蒸消毒剂对养殖圈舍物表及空气均具有良好的杀菌效果,应用前景广泛。

The fumigation disinfectant prepared by sodium dichloroisocyanurate and glutaraldehyde has the advantages of convenient operation,safety,and no need flame ignition.Research on smoke generation and combustion effects found that the optimal ratio of glutaraldehyde to sodium dichloroisocyanurate is 1∶4.Measure the fumigation and disinfection effect on the breeding farm by positioning sampling and plate sedimentation method were used for sampling and cultivation before and after disinfection.The results showed that the comprehensive sterilization rate of the surface of the enclosure reached over 99%,the comprehensive sterilization rate of the air inside the enclosure reaches 98%and the comprehensive sterilization rate of the surface of the incubation room reaches over 99.99%.The experiment shows that the chlorine glutaraldehyde fumigation disinfectant has good bactericidal effects on the surface of the enclosure and the air,and has a wide application prospect.
