KX强化碱性戊二醛是含强化戊二醛、碳酸氢钠、亚硝酸钠等成分的复方消毒剂。为了解其杀灭微生物效果与腐蚀性,进行了载体定量杀菌试验、金属腐蚀试验。结果,以其含戊二醛 20 000 mg/L原液对不锈钢片表面枯草杆菌黑色变种芽胞作用3h,含戊二醛800mg/L稀溶液对金黄色葡萄球菌作用10min,杀灭率均为100%;以其原液作用20min,可将不锈钢片表面HBsAg抗原性破坏。小牛血清对其杀菌效果影响不明显。其原液对铝腐蚀速率为 0.0092mm/a,对不锈钢、铜、碳钢腐蚀速率均<0.0050mm/a。未加碳酸氢钠、亚硝酸钠的该液存放于54℃ 14d,戊二醛含量下降率为25%。该剂为对金属腐蚀性较小、二元存放较稳定的消毒剂。
KX enhanced alkaline glutaraldehyde is a compound disinfectant containing fortified glutaraldehyde, sodium bicarbonate, sodium nitrite and other ingredients. In order to understand its effect of killing microorganisms and corrosive, carrier quantitative sterilization test, metal corrosion test. The results showed that the killing rate of Bacillus subtilis var. Albus on the surface of stainless steel was 3 h with 20 000 mg / L glutaraldehyde solution and 10% glutaraldehyde diluted solution containing 800 mg / L glutaraldehyde, the killing rate was 100% ; The role of its stock solution for 20min, stainless steel surface HBsAg antigenic destruction. The effect of calf serum on bactericidal effect was not obvious. Its liquid aluminum corrosion rate of 0.0092mm / a, stainless steel, copper, carbon steel corrosion rate <0.0050mm / a. The solution without sodium bicarbonate and sodium nitrite was stored at 54 ℃ for 14 days and the rate of decrease of glutaraldehyde content was 25%. The agent is less corrosive to the metal, binary storage more stable disinfectant.
