特殊生物矿物源双机抗菌陶瓷的除菌性能分析

The evaluation of antibacterial effect of a special kind of bio-mineral source organic and inorganic antibacterial ceramics

目的:对特殊生物矿物源双机抗菌陶瓷的除菌性能进行评估。方法:采用浸渍振荡法进行定量除菌试验、稳定性试验和耐久性试验。结果:对大肠杆菌、金黄色葡萄球菌以及白色念珠菌的10 min平均除菌率均为99.99%;在54℃恒温培养箱中存放14 d后,10 min平均除菌率仍为99.99%;经酸性和碱性介质浸泡3 h和90 d后,对大肠杆菌作用24 h的除菌率分别均为99.99%和99.9%。结论:特殊生物矿物源双机抗菌陶瓷具有快速、高效、稳定以及耐久的除菌性能。

Objective： To evaluate the antibacterial effect of the special bio - mineral source organic and inorganic antibacterial ceramics. Methods： Quantitative sterilization test, stability test and durability test were performed by using impregnation oscillatory method to evaluate the antibacterial effect of the special ceramics. Results： The average rates of 10 - minute sterilization with regard to the Escherichia coli, Staphylococcus aureus and Candida al- bicans were all 99.99% ; The average rate of 10 - minute sterilization still remained 99.99% after the special ceramics＇ incubation in a 54℃ incubator for 14 days; The 24 -hour sterilization rates of the special ceramics （after soaked in acid and alkaline medium for 3 hours and 90 days） with regard to Escherichia coli were 99.99% and 99.9%, respectively. Conclusion： The antibacterial effect of the special bio - mineral source organic and inorganic antibacterial ceramics is quick, efficient, stable and durable.
