Kuyini Ukusetshenziswa kwe-TiO2 Kokhonkolo?

I-Titanium dioxide (TiO2) iyisengezo esisebenza ngezindlela eziningi esithola ukusetshenziswa okuningana ekwakhekeni okukhonkolo ngenxa yezakhiwo zayo ezihlukile.Okunye ukusetshenziswa okuvamile kwe-TiO2 kukhonkolo kufaka phakathi:

1. Umsebenzi we-Photocatalytic:

I-TiO2 ibonisa umsebenzi we-photocatalytic uma ichayeke ekukhanyeni kwe-ultraviolet (UV), okuholela ekulimaleni kwezinhlanganisela zezinto eziphilayo kanye nokungcola okungaphezulu kukakhonkolo.Lesi sakhiwo sinenzuzo ikakhulukazi ekwehliseni ukungcoliswa komoya kanye nokwenza ngcono izinga lomoya ezindaweni zasemadolobheni.Izindawo zikakhonkolo eziqukethe i-TiO2 zingasiza ekwehliseni ukungcola okuhamba komoya njengama-nitrogen oxides (NOx) nama-volatile organic compounds (VOCs), okunikela ezindaweni zasemadolobheni ezihlanzekile nezinempilo.

2. Izindawo Ezizihlanzayo:

Ama-nanoparticles e-TiO2 afakwe kukhonkolo angakha izindawo ezizihlanzayo ezixosha ukungcola, ukungcola, nezinto eziphilayo.Uma icushwe ukukhanya kwelanga, ama-nanoparticles e-TiO2 akhiqiza izinhlobo ze-oxygen esebenzayo (ROS) ezikhipha i-oxidize futhi zibolise izinto eziphilayo phezu kukakhonkolo.Lo mphumela wokuzihlanza usiza ukugcina ukubukeka kobuhle nokuhlanzeka kwezakhiwo zikakhonkolo, ukunciphisa isidingo sokuhlanza nokugcinwa njalo.

3. Ukuqina Okuthuthukisiwe:

Ukwengezwa kwe-TiO2 nanoparticles kukhonkolo kungathuthukisa ukuqina kwayo nokumelana nokucekelwa phansi kwemvelo.I-TiO2 isebenza njenge-photocatalyst ekhuthaza ukubola kokungcola kwemvelo, inciphisa ukunqwabelana kokungcola ebusweni bukakhonkolo.Lokhu, futhi, kusiza ukunciphisa imithelela yesimo sezulu, ukungcola, nokukhula kwe-microbial, ukwandisa impilo yesevisi yezakhiwo ezikhonkolo ezivezwe izimo zangaphandle.

4. Izakhiwo ezibonisa ukukhanya:

Ama-nanoparticles e-TiO2 angadlulisela izakhiwo ezikhanyayo ezindaweni ezikhonkolo, ehlise ukumunca ukushisa futhi anciphise umphumela wokushisa wesiqhingi sasemadolobheni.Ukhonkolo onombala okhanyayo oqukethe izinhlayiya ze-TiO2 ubonisa ukukhanya kwelanga okwengeziwe futhi umunca ukushisa okuncane uma kuqhathaniswa nokhonkolo ovamile, okuholela emazingeni okushisa aphansi kanye nokuncipha kokusetshenziswa kwamandla ukuze kuphole ezindaweni zasemadolobheni.Lokhu kwenza ukhonkolo olungisiwe we-TiO2 ulungele izinhlelo zokusebenza ezinjengama-pavements, imigwaqo yaseceleni, nama-pavements asemadolobheni.

5. Izakhiwo ezilwa ne-Microbial:

Ama-nanoparticles e-TiO2 aboniswe ukubonisa izici zokulwa namagciwane, avimbela ukukhula kwamagciwane, isikhunta, nolwelwe endaweni ekhonkolo.Lo mphumela we-antimicrobial usiza ukuvimbela ukwakheka kwama-biofilms, amabala, kanye nephunga elimnandi ezakhiweni ezikhonkolo, ikakhulukazi ezindaweni ezinomswakama nezinomswakama lapho ukukhula kwe-microbial kudlangile.Ukhonkolo oshintshiwe we-TiO2 ungaba negalelo ekuthuthukisweni kwenhlanzeko nokukhucululwa kwendle ezindaweni ezifana nezibhedlela, amalabhorethri, nezindawo zokucubungula ukudla.

Isiphetho:

Sengiphetha, i-Titanium dioxide (TiO2) isebenzisa izinjongo eziningi ekwenziweni okuphathekayo, enikeza izinzuzo ezifana nomsebenzi we-photocatalytic, izici zokuzihlanza, ukuqina okuthuthukisiwe, izindawo ezikhanyayo, kanye nemiphumela elwa namagciwane.Ngokuhlanganisa ama-nanoparticles e-TiO2 ezixubeni zikakhonkolo, onjiniyela nabadwebi bezakhiwo bangathuthukisa ukusebenza, ukuphila isikhathi eside, nokusimama kwezakhiwo zikakhonkolo kuyilapho bebhekana nokukhathazeka kwemvelo nempilo.Njengoba ucwaningo nentuthuko ku-nanotechnology iqhubeka nokuthuthuka, ukusetshenziswa kwe-TiO2 kukhonkolo kulindeleke ukuthi kudlale indima ebalulekile embonini yezokwakha, kunikeze izixazululo ezintsha zengqalasizinda yasemadolobheni kanye nokusimama kwemvelo.
