80%Cu-20%Zn 합금으로 제작된 필터의 항균성에 대한 연구

Abstract

The lives of modern people have been improved, so the improvement of the indoor air quality is strongly demanded. HEPA and activated carbon filter are the most used in air purification system. To remove biological air pollutants, methods such as UV / photocatalytic device and ozone generator are used. These methods have disadvantages such as additional energy consumption, high corrosiveness, toxicity. In order to overcome these disadvantages, an antibacterial copper filter was fabricated. In this study, the antibacterial activity of antibacterial copper filter was tested sequentially from the laboratory stage to the real life stage. The results of the test using two kinds of fungi (P. pinophilum, C. globosum) showed that fungi completely died after 24 hours from the contact with the antimicrobial copper. As a result of applying it as a filter to a chamber and an air purifier, the antibacterial activity was higher than that of a general antimicrobial HEPA filter. Also, as a filter for system air conditioner, the antibacterial activity was lowered in offices and hospitals. In conclusion, the antimicrobial activity of the antibacterial copper filter requires more research on the preparation method and materials, but it has sufficient antibacterial activity as an antibacterial filter.
