3. Kev siv nyiaj tsim nyog — TiO₂ muaj ntau thiab pheej yig dua piv rau lwm cov photocatalysts xws li zinc oxide (ZnO) lossis tungsten trioxide (WO₃), ua rau nws siv tau rau cov neeg siv khoom tsim cov tshuab lim cua ntau.
Cov Kev Cai Siv Lub Teeb UV rau TiO₂ Ua Haujlwm
Kev ntxuav photocatalyst vam khom lub teeb UV uas phim zoo. TiO₂ xav tau lub teeb UV nrog qhov ntev ntawm 385nm lossis luv dua (UV-A ntau yam) kom ua haujlwm. Cov kev xav tseem ceeb rau cov chaw tsim khoom:
• UV-A (365nm) — Feem ntau pom. Muaj kev nyab xeeb rau kev siv tas mus li, siv hluav taws xob tsawg dua. Ua haujlwm zoo nrog anatase TiO₂.
• UV-C (254nm) — Muaj zog dua. Muab cov teebmeem tua kab mob ncaj qha nrog rau kev ua haujlwm ntawm photocatalyst. Lub zog siab dua, yuav tsum tau tiv thaiv tag nrho.
• Teeb UV uas siv LED piv rau teeb mercury UV — Cov teeb LEDs raug nyiam ntau zuj zus vim lawv lub neej ntev dua (10,000+ teev), muaj peev xwm qhib tau tam sim ntawd, thiab tsis muaj teeb meem pov tseg mercury.
• Qhov muaj zog ntawm UV ncaj qha cuam tshuam nrog qhov nrawm ntawm kev ntxuav. Qhov muaj zog ntau dua = ntau cov hydroxyl radicals = kev rhuav tshem cov pa phem sai dua.
Cov Xwm Txheej Zoo Tshaj Plaws rau Daim Ntawv Thov rau Photocatalyst Purifiers
Txawm hais tias cov thev naus laus zis photocatalyst tuaj yeem koom ua ke rau hauv feem ntau cov tshuab lim cua, qee qhov kev siv tau txais txiaj ntsig tsis sib npaug los ntawm nws lub peev xwm rhuav tshem tshuaj lom neeg tshwj xeeb:
✓ Lub tsev tshiab / chaw ua haujlwm tshiab — Formaldehyde thiab VOC tawm cov pa roj los ntawm cov xim tshiab, rooj tog, thiab pem teb. Photocatalyst yog ib qho ntawm ob peb lub thev naus laus zis uas ua rau cov tshuaj no puas tsuaj es tsis yog tsuas yog ntes lawv xwb.
✓ Cov tsev kho mob thiab cov chaw kho mob — Kev txo cov kab mob thiab cov kab mob hauv chav tos thiab thaj chaw kho mob tas mus li. Kev sib xyaw ua ke ntawm UV-C + photocatalyst muab kev tswj cov kab mob ntawm qhov chaw thiab hauv huab cua.
✓ Cov chaw tsim khoom / chaw tsim khoom — VOC thiab kev tswj pa taws uas cov lim dej carbon yuav nqus sai sai. Cov chaw photocatalyst tuaj yeem khiav tas li yam tsis tas hloov cov khoom siv.
✓ Cov tsev neeg uas muaj tsiaj thiab haus luam yeeb — Cov ntxhiab tsw uas cov lim dej carbon tsis tuaj yeem nqus tau tag nrho raug rhuav tshem ntawm theem molecular los ntawm hydroxyl radicals.
Kev Ua Tau Zoo Hauv Lub Ntiaj Teb Tiag: Cov Kev Ntsuas Hauv Chav Kuaj Qhia Li Cas
Kev sim tshuaj ntsuam xyuas ywj pheej ntawm TiO₂-based photocatalyst air purifiers qhia tau tias muaj cov txiaj ntsig zoo sib xws thoob plaws ntau pawg neeg ua pa phem:
