Daim ntawv thov ntawm silica hauv cov ntaub ntawv siv tshuaj tiv thaiv
Raws li qhov tshwj xeeb qhov chaw loj, ntau tus qauv tsim tawm, muaj zog adsorption muaj peev xwm thiab cov khoom siv lub cev thiab tshuaj muaj zog ntawm ultrafine silica, cov nyiaj ions thiab lwm yam ions tau ua kom haum rau hauv qhov chaw ntawmultrafine silica,thiab kev tsim kho kom ruaj khov thiab ua kom ruaj khov, kub tiv taus, tiv thaiv cov tshuaj tua kab nano tua cov hmoov (tsuas yog txog 70 nm hauv taub) tau zoo tsim nws tau mus txog lossis dhau ntawm cov khoom zoo sib xws ntawm Nyij Pooj. Tom qab kuaj, thaum cov dej concentration ntawm nano antibacterial hmoov tsuas yog 0.315, lub peev xwm antibacterial ntawm gram-zoo thiab gram-tsis zoo tus neeg sawv cev cov kab mob tau pom tseeb heev, qhov chaw txwv tsis pub pom 2-3 hli, thiab nrog qhov nce ntawm nano antibacterial hmoov hauv dej siab, qhov chaw txwv tsis pub muaj ntau ntxiv. Raws li kev txiav txim siab, thaum cov ntsiab lus ntawm Ag + hauv dej yog 0.01mg / l, E.coli hauv dej tuaj yeem tua tau, thiab tuaj yeem tswj tau ntev txog 90 hnub, thiab tsis muaj paj ntoo tshiab ua los ntawm.
Los ntawm kev siv nano antibacterial hmoov nyob rau hauv txha hniav laus lub khob pleev xim, lub tshuab ntxhua khaub ncaws nrog cov pwm pov thawj thiab cov haujlwm muaj tus kabmob tuaj yeem tsim tawm, thiab tus nqi tua kabmob muaj ntau tshaj li 99. Nws tuaj yeem siv rau hauv txha hniav laus txheej hauv qab cov haujlwm hnyav. Nws tseem tuaj yeem tswj cov khoom muaj zog tiv thaiv kab mob tom qab tua hauv cov kua dej muaj zog thiab muaj qhov kub thiab txias (li 900 ℃). Los ntawm kev ntxiv nano antibacterial hmoov mus rau sab hauv phab ntsa txheej, txheej txheej sab hauv phab ntsa nrog cov kab mob ua kom ntev thiab ua haujlwm ua kom muaj peev xwm ua tau. Nano cov tshuaj tua kab mob tau siv hauv cov poj niam' s ris tsho hauv qab xab npum, ntaub plaub, nyiaj cashmere xab npum, tshuaj ntxuav tes, tshuaj ntxuav tes. Nws tau sim los ntawm kev noj qab haus huv thiab kev tiv thaiv kabmob kis mob hais tias cov khoom siv tua kabmob zoo kawg li. Ntxiv mus, nrog kev txhim kho cov neeg' s kev paub txog kev noj qab haus huv, daim ntawv thov ntawm nano tshuaj tua kab mob muaj ntau thiab ntau dua.
