Kev ntsuam xyuas ntawm daim ntawv thov kev ua mob ething oxide sterilizer hauv fumigation kom tsis muaj menyuam ntawm kev cai lij choj refics
1. Pib
Ethylene oxide (EO)Tau siv dav nyob hauv thaj teb ntawm cov tshuaj tua kab mob thiab kom tsis muaj menyuam txij li thaum xyoo 1950 thiab tam sim no tau pom zoo raws li ib qho ntawm cov roj uas muaj peev xwm txhim khu kev txhawb zog. Xyoo 1980, Ethylene Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide Oxide oxide gaside roj kev lag luam, feem ntau yog ua kom muaj kev tiv thaiv kab lis kev cai lij choj xws li cov ntawv sau, xyoob ntoo, ntoo thiab kaus ntxhw. Txawm li cas los xij, vim muaj kev lom zem ntawm ethylene oxide, nws cov teeb meem seem uas tau ib txwm yog ib lub ntsiab lus kub ntawm kev tshawb fawb.
Hauv kev ua haujlwm kom tsis muaj menyuam kom tsis muaj menyuam, kev siv ethylene oxide muaj tus qauv paub tab, xws li ISO 10993-7: 2008. Txawm li cas los xij, cov kab lis kev cai relics tiv thaiv kev lag luam tseem tsis tau tsim cov koom ua ke tsis muaj menyuam kom tsis muaj menyuam. Tsis tas li ntawd, qhov tsis yooj yim thiab tsis pub dawb ntawm kev coj noj coj ua yuav tsum tau ua kom tsis muaj menyuam txoj kev nyab xeeb. Txoj kev kawm no siv ethylene oxide oxide sterizer kom ntsuas kom muaj kev tiv thaiv kev coj noj coj ua los ntawm kev ua kom tsis muaj menyuam, cov khoom cuam tshuam thiab seem.
2. Cov ntaub ntawv thiab cov hau kev

Ntim khoom: nplej ntawv, tsis-ntaub ntaub, PE tus kheej-sealing hnab, PVC yas thooj voos kheej, thiab lwm yam.
Cov twj thiab cov khoom siv: 3m ethylene oxide oxide sterilizer, me mecopic infrared analyzer, spectrophotometer, thiab lwm yam.
Reagents: Ethylene Oxide Gas, Bacillus subtilis dub variant biological biologator, PDA Culture Nruab Nrab, thiab lwm yam.
2.2 kev sim
Kev ntsuam xyuas cov ntawv khoom ua tau zoo: sim cov tensile muaj zog thiab folding cov ntawv ua ntej thiab tom qab ua kom tsis muaj menyuam yaus, txheeb xyuas lub micrrared spectrum thiab xim hloov.
Kev ntsuam xyuas ntawm cov nyhwm nkag ntawm cov khoom ntim ntim khoom: Qhov chaw ntsuas muaj roj ntsha rau hauv cov khoom ntim ntim sib txawv, thiab saib cov txiaj ntsig kev sib txawv tom qab kom tsis muaj menyuam.
Residual Kev Ntsuas Cov Nyiaj: Siv ISO 100993-7: 2008 tus qauv los kuaj cov nqi seem ntawm ethylene oxide tom qab sib zog sab sib txawv.
3. Cov txiaj ntsig thiab kev tshuaj xyuas
3.1 Cov Ethylene ethylene oxide rau ntawm Daim Ntawv Khoom Siv
Cov txiaj ntsig kev sim qhia tau tias tom qab Ethylene Oxide Sterilization, lub tensile muaj zog thiab folding cov ntawv tsis tau hloov pauv tau ntau (rooj 1). Cov microscocic infrared spectrum tsom tau hais tias cov tshuaj lom neeg muaj pes tsawg leeg, qhia tau tias ethylene oxide muaj cov khoom siv ntawm cov organic kab lis kev cai lij choj. Ib qho ntxiv, cov ntawv xeem xim qhia tau tias cov xim sib txawv (△ e tus nqi) ntawm kev ua kom tsis muaj menyuam yaus ua ntej 5, uas tsis tshaj qhov uas tuaj yeem sib txawv los ntawm tib neeg lub qhov muag.

3.2 Kev Khaus Ua Kaus Axide Oxide Kev nkag rau cov khoom sib txawv ntawm cov khoom ntim sib txawv
Qhov kev sim pom tias ethylene oxide tuaj yeem nkag rau ntau cov ntaub ntawv ntim xws li cov nplej nplej, thiab PE ziplock hnab, thiab cov ua kom tsis muaj menyuam yog qhov zoo. Ntawm lawv, pvc yas yas thiab ntawv yas ziplock hnab tuaj yeem thaiv kev sib khi ntawm cov av noo-rhiab kab ke.
3.3 Kev tsom xam ntawm cov nqi uas tseem tshuav tom qab Ethylene Oxide Sterilization
Los ntawm kev nthuav tawm lub zog mus rau 12 teev, ethylene oxide restidual tus nqi tuaj yeem txo mus rau qib kev nyab xeeb (<4 mg/m³). The experiment also found that wood materials have a strong adsorption capacity for ethylene oxide, and the loading amount needs to be appropriately reduced and the exhaust time needs to be extended.
4. Sib Tham
Qhov kev kawm no qhia txog kev siv tshuaj tiv thaiv kev kho mob oxide sterilizers hauv kev tiv thaiv kab lis kev cai. Thaum lub sijhawm ua kom tsis muaj menyuam, kev tswj ntawm qhov kub thiab cov av noo yog qhov tseem ceeb heev. Cov xwm txheej ntawm 37℃thiab Rh60% tsis tuaj yeem tsuas yog ua kom tsis muaj menyuam, tab sis kuj txo qis kev puas tsuaj rau kab lis kev cai lij choj. Ib qho ntxiv, cov kev xaiv ntawm cov khoom ntim ntim tsis tsuas yog cuam tshuam rau cov nyhuv tsis muaj menyuam, tab sis kuj ua kom lub sijhawm khaws cia ntawm kev sib koom ua ke.
Txawm li cas los xij, qhov toxicity ntawm ethylene oxide tseem xav tau yuav tsum tau ua tiag tiag. Nws raug nquahu kom ua pa rau ib lub lim tiam tom qab kom tsis muaj menyuam ua ntej cia, thiab nruj tswj lub sijhawm ntawm cov neeg ua haujlwm. Future research can further optimize the sterilization parameters to meet the needs of cultural relics of different materials.
5. Xaus
Kev Kho Mob Ethylene Oxide Sudilizer muaj qhov tseem ceeb hauv kev tiv thaiv kev tiv thaiv:
Lub tsis muaj menyuam nyhuv yog txhim khu kev qha thiab muaj qhov cuam tshuam me me rau cov khoom ntawm cov kev cai lij choj kev cai lij choj.
Kev siv tsheb ua haujlwm tau zoo dua kev nyab xeeb.
Qhov kev xaiv ntawm cov khoom ntim khoom tuaj yeem ua kom zoo zam cov kev paug theem nrab.
Nws raug nquahu kom tsim tus kheej cov phiajcim tus kheej raws li cov yam ntxwv ntawm cov ntaub ntawv relic thiab txuas ntxiv txhawb kev tshawb fawb ntxiv.
