【摘要】：目的研究低溫等離子體在滅菌過(guò)程中過(guò)氧化氫氣體擴(kuò)散和等離子放電殺菌效果,探討滅菌過(guò)程的主導(dǎo)因素。方法采用載體定量殺菌試驗(yàn)方法,分別觀察過(guò)氧化氫低溫等離子體滅菌過(guò)程中過(guò)氧化氫擴(kuò)散和等離子體放電的殺菌效果。結(jié)果在過(guò)氧化氫低溫等離子體滅菌裝置設(shè)定條件下,滅菌腔內(nèi)溫度50℃、過(guò)氧化氫擴(kuò)散2.5 mg/L,不啟動(dòng)放電過(guò)程,作用42 s可完全殺滅載體上嗜熱脂肪肝菌芽孢。在滅菌腔內(nèi)溫度50℃條件下,不用過(guò)氧化氫氣體,僅啟動(dòng)等離子放電作用15 min,對(duì)載體上嗜熱脂肪肝菌芽孢殺滅對(duì)數(shù)值2.0。結(jié)論在過(guò)氧化氫低溫等離子體滅菌過(guò)程中,其主導(dǎo)殺菌作用是氣化過(guò)氧化氫及其擴(kuò)散狀態(tài),等離子放電僅起到輔助作用。
[Abstract]:Objective to study the diffusion of hydrogen peroxide gas and the bactericidal effect of plasma discharge in the sterilization process of low temperature plasma, and to explore the leading factors in the sterilization process. Methods the bactericidal effect of hydrogen peroxide diffusion and plasma discharge during hydrogen peroxide low temperature plasma sterilization was observed by carrier quantitative germicidal test. Results under the setting condition of hydrogen peroxide low temperature plasma sterilization device, the sterilized cavity temperature was 50 鈩，
