Dioxyde ya Nano-titanium TIO2 ifite ibikorwa byinshi byo gufotora kandi ifite ibikoresho byiza bya optique.Hamwe nimiterere ihamye yimiti nisoko ryinshi ryibikoresho fatizo, kuri ubu ni fotokateri itanga icyizere.

Ukurikije ubwoko bwa kristu, irashobora kugabanywamo: T689 rutile nano titanium dioxyde na T681 anatase nano titanium dioxyde.

Ukurikije imiterere yacyo, irashobora kugabanywamo: hydrophilique nano titanium dioxyde na lipophilique nano titanium dioxyde.

   Nano titanium dioxyde TIO2ahanini ifite uburyo bubiri bwa kristu: Anatase na Rutile.Dioxyde ya Rutile ya titanium irahagaze neza kandi yuzuye kuruta dioxyde de anatase titanium, ifite ubukana bwinshi, ubucucike, icyerekezo cya dielectric gihoraho kandi cyangiritse, kandi imbaraga zayo zo kwihisha hamwe nimbaraga zo gusiga nabyo biri hejuru.Dioxyde ya anatase yo mu bwoko bwa anatase ifite uburyo bwo kwigaragaza cyane mu gice kigufi cy’umucyo ugaragara kuruta dioxyde ya rutile yo mu bwoko bwa rutile, ifite ibara ryijimye, kandi ifite ubushobozi bwo kwinjiza ultraviolet munsi y’ubwoko bwa rutile, kandi ifite ibikorwa byo gufotora birenze ibyo ubwoko bwa rutile.Mubihe bimwe na bimwe, anatase titanium dioxyde irashobora guhinduka dioxyde ya rutile.

Gusaba kurengera ibidukikije:

Harimo no kuvura umwanda uhumanya (hydrocarbone, hydrocarbone ya halogene, aside karubike, aside, amarangi, ibinyabuzima birimo azote, imiti yica udukoko twangiza fosifore, nibindi), kuvura imyanda ihumanya (Photocatalyse irashobora gukemura Cr6 +, Hg2 +, Pb2 +, nibindi). Kwanduza ibyuma biremereye ion) no kweza ibidukikije murugo (kwangirika kwa ammonia yo mu nzu, formaldehyde na benzene ukoresheje icyatsi kibisi gifotora).

Gusaba ubuvuzi:

Dioxyde de Nano-titanium ibora bagiteri ikoresheje fotokatisiti kugira ngo igere kuri antibacterial, yica bagiteri na virusi, kandi irashobora gukoreshwa mu guhagarika no kwanduza amazi yo mu ngo;ibirahure, ububumbyi, nibindi byuzuye TIO2 bifotora bikoreshwa mubikoresho bitandukanye byisuku nkibitaro, amahoteri, ingo, nibindi. Ibikoresho byiza bya antibacterial na deodorizing.Irashobora kandi kudakora selile zimwe na zimwe zitera kanseri.

Ingaruka ya bagiteri ya TiO2 iri mubunini bwayo.Nubwo dioxyde ya titanium (TiO2 isanzwe) nayo ifite ingaruka zifotora, irashobora kandi kubyara electron hamwe nu mwobo, ariko igihe cyayo cyo kugera hejuru yibikoresho kiri hejuru ya microseconds, kandi biroroshye kongera kwiyunga.Biragoye gukoresha ingaruka za antibacterial, hamwe na nano-dispersion ya TiO2, electron nu mwobo ushimishwa numucyo bimuka biva mumubiri bikagera hejuru, kandi bifata gusa nanosekond, picosekond, cyangwa femtosekond.Kwiyongera kwa electron hamwe nu mwobo ni Ukurikije gahunda ya nanosekondi, irashobora kwimuka vuba hejuru, igatera ibinyabuzima bya bagiteri, kandi ikagira ingaruka za antibacterial.

Dioxyde ya Anatase nano titanium ifite ibikorwa byo hejuru, ubushobozi bukomeye bwa antibacterial, kandi ibicuruzwa biroroshye gutatanya.Ibizamini byagaragaje ko dioxyde ya nano-titanium ifite ubushobozi bukomeye bwa bagiteri yo kurwanya Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Salmonella na Aspergillus.Byemejwe cyane kandi bikoreshwa cyane mubicuruzwa bya antibacterial mubijyanye nimyenda, ububumbyi, reberi, nubuvuzi.

Kurwanya igihu no kwisukura:

Munsi ya ultraviolet yumucyo, amazi yinjira rwose muri firime ya dioxyde de titanium.Kubwibyo, gutwikira dioxyde ya nano-titanium ku ndorerwamo zo mu bwiherero, ibirahuri by'imodoka hamwe n'indorerwamo zo kureba inyuma bishobora kugira uruhare mu gukumira igihu.Irashobora kandi kwiyumvamo kwisukura hejuru yamatara yo kumuhanda, kurinda umuhanda, no kubaka amatafari yinyuma.

Imikorere ya Photocatalytic

Ibyavuye mu bushakashatsi byagaragaje ko bitewe n’imirasire y’izuba cyangwa imirasire ya ultraviolet mu mucyo, Ti02 ikora kandi ikabyara radicals yubuntu hamwe nigikorwa kinini cya catalitiki, ishobora kubyara imbaraga zo gufotora no kugabanya imbaraga, kandi irashobora guhagarika no gufotora feri ya feri ya ferdehide ifatanye hejuru. Bya Ibintu.Nkibintu kama nibintu bimwe na bimwe bidasanzwe.Irashobora gukina umurimo wo kweza umwuka wimbere.

Imikorere yo gukingira UV

Dioxyde de titanium yose ifite ubushobozi runaka bwo gukurura imirasire ya ultraviolet, cyane cyane imirasire miremire ya ultraviolet yangiza umubiri wumuntu, UVA \ UVB, ifite ubushobozi bukomeye bwo kwinjiza.Imiti ihebuje yimiti, ituze ryumuriro, kutagira uburozi nibindi bintu.Ultra-nziza ya titanium dioxyde ifite ubushobozi bukomeye bwo kwinjiza imirasire ya ultraviolet bitewe nubunini bwayo buto (mucyo) nibikorwa byinshi.Mubyongeyeho, ifite ibara risobanutse neza, abrasion nkeya, kandi byoroshye gutatanya.Hemejwe ko dioxyde ya titanium ari yo ikoreshwa cyane mu bikoresho byo mu bwoko bwa organic organique mu kwisiga.Ukurikije imikorere yacyo itandukanye yo kwisiga, hashobora gukoreshwa imico itandukanye ya dioxyde de titanium.Umweru na opacite ya dioxyde ya titanium irashobora gukoreshwa mugukora amavuta yo kwisiga afite amabara menshi.Iyo dioxyde ya titanium ikoreshwa nk'inyongeramusaruro yera, T681 anatase titanium dioxyde ikoreshwa cyane cyane, ariko iyo harebwa imbaraga zo guhisha hamwe no kurwanya urumuri, Nibyiza gukoresha dioxyde ya T689 rutile.
