Abstract
Peb cov kev tshawb fawb yav dhau los tau pom tias precoating ntawm cov lim fibers nrog cov tshuaj yej tsob ntoo roj (TTO) txhim kho lub cev sau ua haujlwm ntawm cov pa cua sov, qhov cua, thiab cua txias (HVAC) lim, thiab muab cov nqi zoo thiab ceev ceev inactivation ntawm cov kab mob thiab cov kab mob fungal. lub lim dej. Lub hom phiaj tseem ceeb ntawm txoj kev tshawb no yog txhawm rau tshawb xyuas cov tshuaj tiv thaiv kab mob ntawm ob yam tshuaj tua kab mob, piv txwv li, TTO thiab eucalyptus roj (EUO), tiv thaiv tus kab mob npaws uas ntes tau mus rau qhov chaw lim dej. Nws tau pom tias ob qho tib si kuaj cov roj muaj zog tiv thaiv kab mob thaum siv los ua cov khoom siv fiber ntau, muaj peev xwm ua kom tsis muaj kab mob hauv lub cev tsis pub dhau 5-10 feeb ntawm kev sib cuag ntawm fiber ntau. Cov tshuaj tiv thaiv kab mob ntawm TTO kuj tau ua tiav kev sib tw hauv daim ntawv aerosol los ntawm kev sib xyaw cov kab mob sib kis tau zoo nrog cov roj tee nyob rau hauv lub tshuab aerosol chamber. Cov txiaj ntsig tau zoo heev rau kev txhim kho ntxiv ntawm tus kab mob inactivating cov txheej txheem thiab technologies rau huab cua zoo daim ntaub ntawv.
Taw qhia
Xav txog qhov tseeb tias khaws cov microbial aerosols tseem nyob ntawm qhov chaw lim dej, qee qhov muaj peev xwm ntawm lawv cov nram qab no detachment thiab rov aerosolization rov qab mus rau cov cab kuj tsis tuaj yeem tsis quav ntsej. Cov re-aerosolized particles tseem muaj sia nyob ua rau muaj kev pheej hmoo loj heev rau cov neeg nyob hauv thiab ib puag ncig. Qhov teeb meem no tuaj yeem daws tau los ntawm kev ntxiv cov tshuaj tua kab mob rau hauv cov cab kuj roj lossis ua qee cov txheej txheem inactivation ncaj qha rau ntawm qhov chaw lim, ua rau cov kab mob microbial inactive nyob rau hauv cov ntaub ntawv ntawm re-aerosolization.
Muaj qee qhov kev siv thev naus laus zis muaj rau kev tua kab mob microbial. Lawv suav nrog photocatalytic decomposition ntawm microbes ntawm titanium oxide nto irradiated los ntawm ultraviolet (UV; Vohra li al. 2006; Grinshpun li al. 2007), infrared (IR) hluav taws xob raws li thermal decomposition (Damit et al. 2011), siv cov tshuaj ncaj qha rau hauv. mus rau hauv lub tshuab nqa huab cua los yog siv rau hauv cov lim dej (Pyankov li al. 2008; Huang et al. 2010), thiab lwm yam. Ntawm cov tshuaj tua kab mob ntau yam, qee cov roj ntuj zoo li pheej hmoo vim qhov qis lossis tsis muaj tshuaj lom, tshwj xeeb tshaj yog nyob rau hauv daim ntawv diluted (Carson et al. 2006). Nyob rau xyoo kaum xyoo dhau los, ntau yam roj yam tseem ceeb los ntawm cov nroj tsuag tau raug tshuaj xyuas los soj ntsuam lawv cov tshuaj tiv thaiv kab mob (Reichling li al. 2009).
Kev siv cov roj muaj peev xwm, xws li tshuaj yej tsob ntoo roj (TTO) thiab eucalyptus roj (EUO), raws li cov tshuaj tua kab mob tau pom meej meej hauv cov kev tshawb fawb hauv vitro hais txog cov kab mob (Wilkinson thiab Cavanagh 2005; Carson et al. 2006; Salari li al. 2006 ; Hayley thiab Palombo 2009), tshuaj tua kab mob (Hammer et al. 2000; Oliva et al. 2003), thiab tshuaj tiv thaiv kab mob (Schnitzler li al. 2001; Cermelli li al. 2008; Garozzo et al. 201). Tsis tas li ntawd, nws tau pom tias cov roj tseem ceeb yog cov sib xyaw ua ke, nrog rau cov khoom sib txawv ntawm cov khoom sib txawv, nyob ntawm qhov kev loj hlob ntawm cov nroj tsuag (Kawakami li al. 1990; Moudachirou li al. 1999). Cov tshuaj tiv thaiv kab mob ntawm TTO yog ntaus nqi rau terpinen-4-ol (35-45%) thiab 1,8-cineole (1-6%); Txawm li cas los xij, lwm yam khoom xws li a-terpineol, terpinolene, thiab a- thiab c-terpinene kuj tseem muaj feem ntau thiab muaj feem cuam tshuam rau kev tua kab mob microbial (May et al. 2000). Lub EUO los ntawm ntau hom Eucalyptus muaj 1,8-cineole, a-pinene, thiab a-terpineol ua cov ntsiab lus tseem ceeb (Jemâa li al. 2012). Ib qho tshuaj muab qhab nia EUO feem ntau muaj ntau txog 70% concentration ntawm 1,8-cineole.
Tsis ntev los no, peb tau tawm tswv yim siv tshuab raws li txheej txheej fiber ntau lim los ntawm TTO, thiab tshaj tawm cov txiaj ntsig ntawm kev tshawb fawb txog kev tua kab mob (Pyankov li al. 2008) thiab cov kab mob fungal (Huang et al. 2010). Hauv cov kev tshawb fawb no, TTO tau siv los ua ob qho tib si, lim kev ua haujlwm pab txhawb kev tshaj tawm thiab tshuaj tua kab mob ntawm cov kab mob thiab cov kab mob fungal uas ntes tau ntawm lub lim dej. Xav txog tam sim no muaj kev txaus siab rau kev tshawb fawb txog kev mob khaub thuas, txoj kev tshawb fawb tam sim no yog qhov kev tshawb fawb txuas ntxiv ntawm peb cov kev tshawb fawb yav dhau los nrog rau kev tsom mus rau kev ntsuam xyuas ntawm cov tshuaj tiv thaiv kab mob ntawm cov roj yam tseem ceeb (TTO thiab EUO) ntawm kev tsis ua haujlwm ntawm tus kab mob khaub thuas.
