Maxaa loo isticmaalaa Titanium Dioxide?
Meelaha codsiga dhaqameed
1. Midabada iyo walxaha qarinaya
Warshadaha dahaadhka: Sida midab cad, waxay keentaa cadaan sare (L>98) iyo awood qarsoon oo xooggan (>95%) dahaarka iyadoo hagaajinaysa iska caabbinta cimilada (imtixaanka QUV-A 2000h).
Balaastikada iyo sameynta warqadda: Waxay kordhisaa daah-furnaanta (>90%) iyo sifooyinka ka hortagga huruudaynta ee alaabada balaastikada ah; waxaa loo isticmaalaa daawaynta dusha sare ee warqadda heerka sare ah si loo hagaajiyo dhalaalka iyo daabacaadda.
2. Dhoobada iyo dhaldhalaalka
Wax ka beddelka dhaldhalaalka: Iyada oo ah wakiil gaashaan iftiin iyo wakiil caddeynaya, waxay hagaajin kartaa adkaanta (adagaanshaha Mohs ≥ 6), dhalaalka (milicsiga > 85%) iyo iska caabbinta aashitada (iska caabbinta 10% xalka HCl > 24 saacadood) ee dusha sare ee dhaldhalaalka.
3. Kiimikooyinka maalinlaha ah iyo cuntada
Badeecadaha ka hortagga qorraxda: Bixi ilaalinta qorraxda ee jirka iyadoo la kala firdhinayo fallaaraha ultraviolet (UVA/UVB), iyo TiO₂-ka cabbirka nano (cabirka walxaha ≤100nm) ayaa ka fogaan kara dareenka dhegdheg ee maqaarka.
Cuntada lagu daro: Maadaama ay tahay midab cad oo aan sun ahayn (oo waafaqsan FDA 21CFR73.575), waxaa loo isticmaalaa in lagu caddeeyo nacnaca, waxyaabaha caanaha laga sameeyo, iwm.

Meelaha soo baxaya ee codsiyada
1. Maamulka deegaanka
Burburka balaastikada: Walxaha titanium dioxide ee sabeynaya waxaa lagu burburin karaa xaalado dhexdhexaad ah iyada oo loo marayo lakabka hydrophobic ee dusha sare iyada oo aan loo baahnayn daaweyn aashito/alkali oo xooggan, taasoo kordhinaysa waxtarka kala-goynta balaastikada polyethylene tobanaan jeer, iyadoo ethanol ay tahay 40% badeecada.
Nadiifinta hawada: Nano-TiO₂ photocatalyst oo 5nm firfircoon ayaa burburin kara wasakhowga sida formaldehyde iyo benzene (heerka burburka > 98%), muuqaalkiisa ficilkuna wuxuu ku fidsan yahay ilaa xadka iftiinka ee la arki karo (ka sarreeya 400nm).
2. Tiknoolajiyadda Tamarta
Kala qaybinta biyaha sawir-qaadista si loo soo saaro haydarojiin: Rutile-ka Scandium-doped TiO₂ wuxuu kordhiyaa hufnaanta kala-soocidda dallacaadda sawir-qaadista 200 jeer, heerka wax-soo-saarka haydarojiinkuna waa 15 jeer ka badan walxaha dhaqameed (iyadoo la adeegsanayo iftiinka qorraxda ee la sawiray).
Agab tamar cusub: waxaa loo isticmaalaa dahaarka elektroodka wanaagsan ee baytariga lithium si loo joojiyo falcelinta dhinaca elektroodka loona hagaajiyo xasilloonida wareegga (>4000 jeer @80% SOH).
3. Wax ka beddelka walxaha shaqeynaya
Dahaarka bakteeriyada: Nano-titanium sol wuxuu dhex galaa substrate-ka si uu u sameeyo lakab cufan, iyadoo heerka dilka uu yahay >98% marka loo eego E. coli iyo bakteeriyada kale, iyo hoos u dhaca waxqabadka oo ah <5% ka dib marka uu gaboobo muddo 5 sano ah.
Qalabka dhismaha ee aadka u adkaysta cimilada: TiO₂ oo naadir ah oo lagu dahaadhay cerium-ka dhulka ayaa xoojiya iska caabbinta UV ee dahaarka derbiga dibadda (heerka ilaalinta UVA > 99%) waxayna hagaajisaa iska caabbinta barafowga iyo dhalaalka 50%.
Dahaarka indhaha: Astaamaha tusmada iftiinka sare leh (nd=1.75-2.20) ayaa loo isticmaalaa dahaarka ka hortagga milicsiga si loo yareeyo khasaaraha indhaha ee aaladaha laysarka (<0.1dB/km).
4. Katalisyada Warshadaha ee Gaarka ah
Isku-darka Kiimikada: Sida kicinta epoksaydhka olefin, heerka beddelka waa >95%; nidaamka wax soo saarka hydrogen-ka kala qaybiya biyaha sawir-qaadista, waxaa lagu daraa CdS si loo hagaajiyo waxtarka wax soo saarka haydarojiinta.
