Yas thiab ua ntawv: Ua kom cov khoom opacity (> 90%) thiab cov khoom tiv thaiv kev daj ntawm cov khoom yas; siv rau kev kho qhov chaw ntawm cov ntawv qib siab kom txhim kho qhov ci ntsa iab thiab kev luam ntawv.
2. Cov khoom siv ua los ntawm av nplaum thiab cov xim pleev xim
Kev hloov kho glaze: Ua tus neeg sawv cev tiv thaiv lub teeb thiab tus neeg sawv cev dawb, nws tuaj yeem txhim kho qhov nyuaj (Mohs hardness ≥ 6), qhov ci ntsa iab (kev cuam tshuam> 85%) thiab kev tiv thaiv kua qaub (kev tiv thaiv rau 10% HCl daws> 24h) ntawm qhov chaw glaze.
3. Cov tshuaj lom neeg thiab khoom noj txhua hnub
Cov khoom siv tiv thaiv hnub: Muab kev tiv thaiv hnub los ntawm kev tawg cov duab ultraviolet (UVA/UVB bands), thiab nano-scale TiO₂ (qhov loj me ≤100nm) tuaj yeem zam kev xav ntawm daim tawv nqaij nplaum.
Cov khoom noj khoom haus ntxiv: Ua ib qho xim dawb uas tsis muaj tshuaj lom (ua raws li FDA 21CFR73.575), nws yog siv rau kev ua kom dawb cov khoom qab zib, cov khoom noj mis nyuj, thiab lwm yam.

Cov cheeb tsam thov tshiab
1. Kev tswj hwm ib puag ncig
Kev puas tsuaj ntawm cov yas: Cov khoom siv titanium dioxide uas ntab tuaj yeem puas tsuaj nyob rau hauv cov xwm txheej nruab nrab los ntawm txheej hydrophobic saum npoo av yam tsis tas yuav muaj kev kho ua ntej nrog cov kua qaub / alkali muaj zog, ua rau muaj kev puas tsuaj ntawm cov yas polyethylene ntau zaus, nrog rau ethanol suav txog 40% ntawm cov khoom.
Kev ntxuav cua: 5nm active nano-TiO₂ photocatalyst tuaj yeem rhuav tshem cov pa phem xws li formaldehyde thiab benzene (degradation rate> 98%), thiab nws cov kev ua haujlwm spectrum txuas mus rau lub teeb pom kev (saum toj no 400nm).
2. Kev Siv Hluav Taws Xob
Kev faib dej photocatalytic los tsim cov hydrogen: Scandium-doped rutile TiO₂ ua rau muaj kev ua haujlwm ntawm kev sib cais them photogenerated los ntawm 200 zaug, thiab tus nqi tsim hydrogen yog 15 npaug ntawm cov ntaub ntawv ib txwm muaj (hauv qab lub hnub ci simulated).
Cov ntaub ntawv siv zog tshiab: siv rau cov roj teeb lithium zoo electrode txheej kom tiv thaiv cov tshuaj tiv thaiv electrode sab thiab txhim kho kev ruaj khov ntawm lub voj voog (> 4000 zaug @ 80% SOH).
3. Kev hloov kho cov khoom siv ua haujlwm
Txheej tiv thaiv kab mob: Nano-titanium sol nkag mus rau hauv lub substrate los tsim ib txheej tuab, nrog rau kev tua tus nqi ntawm > 98% tawm tsam E. coli thiab lwm yam kab mob, thiab kev ua haujlwm poob qis ntawm <5% tom qab laus rau 5 xyoos.
Cov ntaub ntawv siv hauv tsev uas tiv taus huab cua heev: TiO₂ uas muaj cerium tsawg tsawg ua rau cov txheej txheem tiv thaiv UV ntawm cov txheej txheem phab ntsa sab nraud zoo dua (UVA shielding rate > 99%) thiab txhim kho kev tiv thaiv khov-thaw los ntawm 50%.
Txheej kho qhov muag: Cov khoom siv refractive index siab (nd = 1.75-2.20) yog siv rau cov txheej tiv thaiv kev cuam tshuam kom txo qhov poob ntawm qhov muag hauv cov khoom siv laser (<0.1dB/km).
4. Kev Tshuaj Xyuas Kev Lag Luam Tshwj Xeeb
Kev tsim tshuaj lom neeg: Ua ib qho catalyst olefin epoxidation, tus nqi hloov pauv yog> 95%; hauv lub tshuab photocatalytic dej faib hydrogen ntau lawm, nws yog ua ke nrog CdS los txhim kho kev ua haujlwm ntawm hydrogen.
