摘要：

为建立检测抗菌金属材料的抗菌性能的方法。分别用ASTM E2149-13a法和ISO 221962011法对抗菌金属的抗菌性能和适用性进行比对研究,得出这两种方法都不太适合抗菌金属材料的抗菌性能检测。提出适宜于抗菌金属及其制品的抗菌性能检测方法:采用贴膜法,抗菌金属材料与菌液的作用时间为2 h。经实验证明:该方法重复性好、再现性佳,3种不同抗菌剂处理的金属材料抗菌率,其重复性分别为5.5%、5.6%和2.5%,同种抗菌剂处理的金属材料抗菌率的再现性为5.5%,说明该方法能应用于抗菌金属及相关材料抗菌性能检测。

Abstract: The purpose of this paper is to design a detection method for antibacterial properties of antibacterial metallic materials. The antibacterial properties were detected and the applicability thereof was comparatively studied with both the ASTM E2149-13a and ISO 22196——2011 methods. The outcome suggests that the two methods were unsuitable for testing the antibacterial properties of antibacterial metallic materials. Then, a scientific and reasonable detection method was put forward. First, the antibacterial metallic materials and bacterial liquid were mixed with the sticking membrane method to react for 2 hours. It is proved from the test results that this method is stable and highly reproductive. The repeatability of the antibacterial rates of metallic materials treated by three different kinds of antibacterial agents is 5.5%, 5.6% and 2.5% respectively.The reproducibility of the same kind of antibacterial agent is 5.5%. It suggests that the proposed method can be used to detect the antibacterial properties of antibacterial metal and related materials.
