Kodi Titanium Dioxide imagwiritsidwa ntchito bwanji?
Madera ogwiritsira ntchito achikhalidwe
1. Utoto ndi zinthu zobisa
Makampani opanga zophimba: Monga utoto woyera, umapereka kuyera kwambiri (L>98) ndi mphamvu yolimba yobisala (>95%) ku zophimba pamene ukukulitsa kukana kwa nyengo (kupambana mayeso a QUV-A 2000h).
Mapulasitiki ndi kupanga mapepala: Zimawonjezera kuonekera bwino (>90%) komanso mphamvu zoletsa chikasu za zinthu zapulasitiki; zimagwiritsidwa ntchito pochiza pamwamba pa pepala lapamwamba kuti liwoneke bwino komanso kuti lisamasindikizidwe mosavuta.
2. Zoumbaumba ndi enamel
Kusintha kwa Glaze: Monga chotetezera kuwala ndi choyeretsa, chimatha kusintha kuuma (kuuma kwa Mohs ≥ 6), kuwala (kuwunikira > 85%) ndi kukana kwa asidi (kukana yankho la 10% HCl > maola 24) pamwamba pa glaze.
3. Mankhwala ndi chakudya cha tsiku ndi tsiku
Zodzoladzola padzuwa: Zimateteza ku dzuwa mwa kutulutsa kuwala kwa ultraviolet (UVA/UVB bands), ndipo nano-scale TiO₂ (kukula kwa tinthu ≤100nm) zimatha kupewa khungu lomata.
Chowonjezera pa chakudya: Monga utoto woyera wopanda poizoni (wogwirizana ndi FDA 21CFR73.575), umagwiritsidwa ntchito poyeretsa maswiti, mkaka, ndi zina zotero.

Madera omwe akutukuka kumene
1. Kulamulira zachilengedwe
Kuwonongeka kwa pulasitiki: Zinthu zoyandama za titanium dioxide zimatha kuwonongeka pansi pa mikhalidwe yopanda mpweya kudzera pamwamba pa hydrophobic wosanjikiza popanda kufunikira kwa asidi/alkali wamphamvu, zomwe zimawonjezera mphamvu ya mapulasitiki a polyethylene kuwonongeka kambirimbiri, ndipo ethanol imakhala 40% ya chinthucho.
Kuyeretsa mpweya: 5nm yogwira ntchito ya nano-TiO₂ photocatalyst imatha kuwola zinthu zoipitsa monga formaldehyde ndi benzene (chiwopsezo cha kuwonongeka kwa mpweya > 98%), ndipo mphamvu yake imafikira ku gulu lowala looneka (loposa 400nm).
2. Ukadaulo wa Mphamvu
Kugawanika kwa madzi opangidwa ndi photocatalytic kuti apange haidrojeni: TiO₂ yopangidwa ndi Scandium imawonjezera mphamvu ya kulekanitsa mphamvu yopangidwa ndi photogenerated charge ndi nthawi 200, ndipo kuchuluka kwa haidrojeni komwe kumapangidwira ndi nthawi 15 kuposa kwa zipangizo zachikhalidwe (pansi pa kuwala kwa dzuwa).
Zipangizo zatsopano zamagetsi: zimagwiritsidwa ntchito popangira ma electrode okhala ndi batire ya lithiamu kuti ziletse ma electrode kuti asamagwire bwino ntchito komanso kuti zinthu zisamayende bwino (>4000 times @80% SOH).
3. Kusintha kwa zinthu zogwirira ntchito
Chophimba choletsa mabakiteriya: Nano-titanium sol imalowa mu substrate kuti ipange wosanjikiza wokhuthala, ndi kuchuluka kwa kupha kwa >98% motsutsana ndi E. coli ndi mabakiteriya ena, ndipo magwiridwe antchito amachepa ndi <5% pambuyo pa kukalamba kwa zaka 5.
Zipangizo zomangira zomwe sizimavutika ndi nyengo: TiO₂ yopangidwa ndi cerium yosowa kwambiri imawonjezera kukana kwa UV kwa zokutira zakunja kwa makoma (chiwerengero cha chitetezo cha UVA > 99%) ndipo imawonjezera kukana kwa kuzizira ndi 50%.
Chophimba cha kuwala: Makhalidwe apamwamba a refractive index (nd=1.75-2.20) amagwiritsidwa ntchito pophimba choletsa kuwunikira kuti achepetse kutayika kwa kuwala muzipangizo za laser (<0.1dB/km).
4. Katswiri Wapadera wa Zamalonda
Kupanga mankhwala: Monga chothandizira kupopera kwa olefin, kuchuluka kwa kusintha ndi >95%; mu njira yopangira hydrogen yogawanitsa madzi ndi photocatalytic, imaphatikizidwa ndi CdS kuti iwonjezere mphamvu yopangira hydrogen.

Chitetezo ndi Kutsatira Malamulo
Gulu la mayendedwe: Katundu Wosakhala Woopsa (WOSATOPSA)
Chitsimikizo cha chilengedwe:
- RoHS 3.0 (2015/863/EU) Zitsulo zolemera sizinapezeke
- Zinthu zomwe sizinatchulidwe pansi pa REACH SVHC
- Kutsatira Ndondomeko ya Migodi Yotsutsana (CMRT 6.0)
Chitetezo kuntchito: OSHA TWA malire 5mg/m³ (fumbi)
Kusamalitsa
Ntchito za nanopowder zimafuna chitetezo cha kupuma cha N95 (chogwirizana ndi ISO 13137)
Pakugwiritsa ntchito kutentha kwambiri, tikulimbikitsidwa kugwiritsa ntchito mipiringidzo ya corundum
Zakudya/mankhwala ziyenera kupereka zikalata zotsatizana ndi COA ndi FDA

Kufotokozera pamwambapa kumadalira makhalidwe onse a titaniyamu dioxide. Kuti mudziwe njira zina zogwiritsira ntchito ndi magawo ake, chonde onani COA (lipoti lowunikira khalidwe) ndi fayilo ya MSDS.
