Kev ntxuav tus kheej superhydrophilic iav zaj duab xis muaj hom nanomaterials nrog photocatalytic kev ua si. Nws tuaj yeem nqus teeb ntawm ib qho wavelength, tsim cov tshuab ua yeeb yam dawb rau kev rhuav tshem cov kab mob oxidation, yog li tua cov kab mob ideganism, ua tiav lub hom phiaj ntxuav tus kheej. Cov kev tshawb fawb yav dhau los tau pom tias kev tshem tawm cov kuab paug thiab nitrogen sib xyaw ua ke tuaj yeem ua kom haum nrog lub teeb sab hauv tsev. Lub superhydrophilicity ntawm daim nyias nyias yog ntaus nqi rau kev tsim cov cheeb tsam amphipilic saum npoo. Thaum lub teeb ci ntsa iab rau ntawm daim nyias qab hau, cov tub choj oxygen nyob rau hauv lub nplaim membrane nqus lub zog thiab so, ua cov pa oxygen ions. Qhov yav tas yuav nthuav tawm cov dej tsis sib xws ntawm cov dej nyob ib ncig ntawm cov chaw seem dej, thaum lwm lub cheeb tsam tseem ua rau Hydrophobic. Cov tee dej yog ib txwm loj dua (ob peb xaj ntawm ntau) cov cheeb tsam hydrophilic lossis hydrophobic thaj chaw. Yog li ntawd, cov tee dej yuav tag rau hauv daim nyias nyias ntxiv tom qab raug lub teeb rau qee lub sijhawm. Qhov xwm txheej no zoo ib yam li ob-seem ntawm capillary prenomenon. Yog li, microschopically, muaj hydrophobic ib qho chaw nyob ntawm daim nyias nyias, thaum macroscopically, nws qhia superhydrophilicity.
Kev Xav Tau Hauv Lag Luam Xav Tau Kev Xav
Iav yog ib qho ntawm cov khoom tseem ceeb hauv ntau lub teb thiab cov tuam tsev ua lag luam, kev lag luam thiab kev tshawb fawb, thiab tshuaj. Cov kws tshaj lij qhia tias muaj peev xwm tso tawm ib lub hydrok-tu iav uas yog cov tshuaj tiv thaiv kev ua kom sai li sai tau yog qhov kev sib tw kom sai li sai tau yog qhov kev sib tw hauv ntiaj teb tau sib tw thiab npau suav txog niaj hnub no. Kev tu tus kheej iav, vim nws kev ua tau zoo tshaj, tuaj yeem siv dav hauv cov vaj tse kab hlau, lub qhov rai tsom iav, thiab lwm yam khoom lag luam muaj kev cia siab heev. Nws tau tam sim no los ua qhov tseem ceeb ntawm kev muag kub kub thiab ib puag ncig cov iav hauv kev lag luam thoob ntiaj teb.
Tuam Tshoj tus "Nano titanium dioxatural photocatalytic iav" thiab "Tii2 zaj duab xis tu iav" yuav tsis ntev muaj nyob rau hauv cov khoom loj. Qhov no yuav ua kom nrawm nrawm dua kev txhim kho, kev tshawb nrhiav, kev txhawb nqa cov khoom iav, thiab tau dhau los ua zaj duab xis ntawm lub ntsej muag
Tsis tas li ntawd, nrog kev ua tiav hosting ntawm beijing thiab qhib ntawm xyoo 2010 yuav ua rau cov khoom siv nyob ib puag ncig xws li "tus kheej ntxuav iav". Kev ua lag luam rau tus kheej huv kev ntxuav tus kheej yuav muaj kev cog lus thiab muaj lub zeem muag dav dav.
2. Thoob Ntiaj Teb Kev Ua Lag Luam Kev Lag Luam
Thoob ntiaj teb, cov pab pawg British Pilkington, cov iav ayoi, thiab cov iav ua paug, thiab tam sim no muaj kuab lom Nws tau tshaj tawm tias cov hom no titioxatalytic tus kheej iav "nrog ntau hom" tus kheej-ntxuav iav "nrog cov kev ua kom zoo nkauj, yog los tiv thaiv cov tsev pej xeem rau cov tsev nyob. Nkag mus rau hauv chav ua noj thiab chav dej los ntawm cov qhov rooj sab nraud thiab qhov rai, nws cov ntawv thov tau nthuav dav hnub ib hnub. Nws qhov kev thov thiab kev txhim kho muaj peev xwm yog loj heev.
Ib qho ntxiv, Tebchaws Askiv Pilkington Lub tuam txhab iav iav lub tuam txhab "thiab" tiv thaiv kev ua kom zoo dua qub thiab lwm cov khaubncaws sab nraud povtseg ntawm lub ntsej muag. Nws tau tam sim no tau nce qib thiab siv nyob rau hauv cov cheeb tsam xws li Australia thiab North America, thiab tau pib ua neeg nyob hauv cov duab Europe, lwm lub tebchaws thiab Tebchaws Asmeskas. Nws tau tshaj tawm tias txawm hais tias tus nqi ntawm qhov kev ua tau zoo no thiab tiv thaiv lub tuam txhab lwmyam, nws tsis tas yuav tu thiab tu kom huv thiab kev tawm tsam kev tiv thaiv. Vim li no, lub tuam txhab twv kwv yees tias phab ntsa thaiv no yuav raug xaiv rau cov ntaub ntawv kab hlau ntawm cov vaj tse nyob hauv Europe thiab Amelikas. Lawv muaj kev ntseeg siab rau lawv kev ua lag luam thiab kwv yees tias lub tuam txhab yuav muaj ntau pua pua pua pua lab daus las los txeeb txhua xyoo
