I-Nano-titanium dioxide tio2 inomsebenzi ophakeme we-photocatalytic futhi inezakhiwo ezibaluleke kakhulu zokukhanya. Ngezakhiwo ezizinzile zamakhemikhali kanye nemithombo eminingi yezinto zokusetshenziswa ezingavuthiwe, okwamanje kuyinto ethembisa kakhulu ye-photocatalyst.

Ngokusho kohlobo lwe-crystal, lungahlukaniswa lube: T689 rutile nano titanium dioxide kanye ne-T681 Anatase Nato Titanium Dioxide.

Ngokwezici zayo ezingaphezulu, zingahlukaniswa: i-hydrophilic nano titanium dioxide ne-lipophilic nano titanium dioxide.

   Nano titanium dioxide tio2Kakhulu inamafomu amabili e-crystal: i-anatase kanye ne-rutile. URutile Titanium Dioxide uzinzile futhi mnene kune-anatase titanium dioxide, unobulukhuni obuphakeme, ubunzima, i-dielectric ihlala njalo inkomba, namandla ayo okusa acashile nawo aphezulu. I-anatase-uhlobo titonium dioxide inokuvezwa okuphezulu engxenyeni ephakeme yokukhanya okubonakalayo kunokukhanya kwe-titile-uhlobo titonium dioxide, futhi inesilinganiso esiphansi sokufakwa kwe-ultraviolet kunohlobo lwe-ruter, futhi inomsebenzi ophakeme we-photocatalytic kunohlobo lwe-rutile. Ngaphansi kwezimo ezithile, i-anatase titanium dioxide ingaguqulwa ibe yi-rutile titanium dioxide.

Izicelo Zokuvikelwa Kwezemvelo:

Okubandakanya ukwelashwa kokungcoliswa kwe-organic (hydrocarbons, ama-hydrocarbons, ama-carboxylic acid, ama-surfic, ama-nitrogen aqukethe izinambuzane, i-photocatalsis +, i-PB2 +, njll.) Ukungcoliswa kwe-ion sensimbi esindayo) kanye Ukuhlanzwa kwezemvelo kwasendlini (ukuwohloka kwe-Indoor Ammonia, i-formaldehyde ne-benzene by photocatalytic Green Coatings).

Izicelo ekunakekelweni kwempilo:

I-Nano-Titonium Dioxide ibola amagciwane ngaphansi kwesenzo se-Photocatalysis ukufezekisa umphumela we-antibacterial, ukubulala amagciwane namagciwane, futhi angasetshenziselwa ukubulawa kwamagciwane kanye nokubulala amagciwane emanzini asekhaya; Ingilazi, ceramics, njll. Ukulayishwa nge-Tio2 Photocatalysis kusetshenziswa ezindaweni ezahlukahlukene zokuhlanzeka ezifana nezibhedlela, amahhotela, amakhaya, njll. Ingakwazi futhi amaseli athile abangela umdlavuza.

Umphumela we-bactericidal we-tio2 ulele ku-quantum usayizi umphumela. Yize i-titanium dioxide (i-tio2 ejwayelekile) nayo inomphumela we-photocatalytic, ingakwazi futhi ukukhiqiza ama-elektroni bese umgodi, kepha isikhathi sayo sokufinyelela ebusweni bakwezinto ezingenhla kwamasosha, futhi kulula ukubuyisa. Kunzima ukwenza umphumela we-antibactekeli, kanye ne-nano-dispersion degree of tio2, ama-elektroni kanye nezimbobo ezithokozela ukufuduka okuvela emzimbeni, futhi kuthatha kuphela ama-nanoseconds, ama-picosecond, noma ngisho nama-femtosecond. I-templogenation ye-actronenerated ama-elekthronidi kanye nezimbobo zikuhlelekile kwama-nanoseconds, ingangena ngokushesha ebusweni, ihlasele imiphumela yegciwane, futhi idlale umphumela ohambelana ne-antibacterial.

I-anatase nano titanium dioxide inomsebenzi ophakeme kakhulu, amandla aqinile antibacterial, futhi umkhiqizo kulula ukusakazeka. Ukuhlolwa kukhombisile ukuthi iNano-Titonium Dioxide inekhono eliqinile lamagciwane ngokumelene ne-pseudomonas aeruginosa, eScherchechia Coli, staphybhamua, staphylococcus aureus, salmonella ne-aspergillus. Kuvunyelwe kakhulu futhi kusetshenziswe kabanzi emikhiqizweni elwa namagciwane emikhakheni yezindwangu, i-ceramics, irabha kanye nomuthi.

Ukulwa ne-coating kanye nokuzihlanza:

Ngaphansi kwe-Ultraviolet ukukhanya okune-irradiation, amanzi angena ngokuphelele ifilimu ye-titanium dioxide. Ngakho-ke, ukuhlanganisa ungqimba lwe-nano-titonium dioxide ezibukweni zokugezela, ingilazi yemoto kanye nezibuko ezibuyiselwe emuva zingadlala indima ekuvikeleni inkundla. Kungakubona nokuzihlanza kobuso bezibani zasemgwaqweni, ogada abaphezulu, kanye nokwakha amathayili odonga angaphandle.

Umsebenzi we-PhotoCatalytic

Imiphumela yocwaningo ithole ukuthi ngaphansi kwesenzo sokukhanya kwelanga noma i-ultraviolet rays ekukhanyeni, i-ti02 isebenze futhi ikhiqize ama-photooxidation aphezulu anomsebenzi oqinile, futhi angakwazi ukukhiqiza i-photooxehydehyde ehlukahlukene enamathiselwe ebusweni bezinto. Njengezinto eziphilayo nezinye izinto ezihlukile. Ungadlala umsebenzi wokuhlanza umoya wasendlini.

Umsebenzi wokuvikelwa kwe-UV

Noma iyiphi i-titanium dioxide inekhono elithile lokudonsa imisebe ye-ultraviolet, ikakhulukazi imisebe ye-wave-wave ultraviolet eyingozi emzimbeni womuntu, UVA \ UVB, ube nomthamo onamandla wokutholwa. Ukuqina okuhle kwamakhemikhali, ukuqina okushisayo, okungeyona ubuthi nezinye izakhiwo. I-Ultra-Fine Titanium Dioxide inekhono elinamandla lokuthola imisebe ye-ultraviolet ngenxa yosayizi wayo omncane wezinhlayiyana (esobala) nomsebenzi omkhulu. Ngaphezu kwalokho, inethoni yombala ecacile, i-abrasion ephansi, nokusakazeka okuhle okulula. Kunqunywa ukuthi iTitanium Dioxide iyinto esetshenziswa kakhulu engafakwanga kakhulu ye-Inorganic eluhlaza ngezimonyo. Ngokwemisebenzi yayo ehlukile kwezimonyo, izimfanelo ezahlukene ze-titanium dioxide zingasetshenziswa. Ubumsulwa kanye ne-opacity ye-titanium dioxide ingahle isetshenziselwe ukwenza izimonyo zibe nemibala ehlukahlukene. Lapho iTitanium Dioxide isetshenziswa njengesengezo esimhlophe, i-T681 Anatase titanium dioxide isetshenziswa ikakhulukazi, kepha lapho amandla okuhlakala nokuphikiswa kokukhanya kubhekwa, kungcono ukusebenzisa i-T689 rutile titanium dioxide.
