Kedu ihe bụ ojiji TiO2 na Concrete?

Titanium dioxide (TiO2) bụ ihe mgbakwunye na-achọta ọtụtụ ngwa n'ụdị ihe n'ihi ihe pụrụ iche ya.Ụfọdụ ojiji TiO2 a na-ejikarị eme ihe na kọnkịtị gụnyere:

1. Ọrụ Photocatalytic:

TiO2 na-egosipụta ọrụ photocatalytic mgbe ekpughere ya na ìhè ultraviolet (UV), na-eduga na mmebi nke ogige organic na ihe ndị na-emetọ ihe n'elu ihe.Ihe onwunwe a bara uru karịsịa n'ibelata mmetọ ikuku na imeziwanye ikuku ikuku na gburugburu obodo.N'elu kọntakịrị nwere TiO2 nwere ike inye aka ịkụda mmetọ ikuku dị ka nitrogen oxides (NOx) na ogige organic na-agbanwe agbanwe (VOCs), na-enye aka na oghere obodo mepere emepe na-adị ọcha na ahụike.

2. Igwe na-ehicha onwe ya:

TiO2 nanoparticles etinyere n'ime kọmpụta nwere ike ịmepụta ebe na-ehicha onwe ya nke na-achụpụ unyi, unyi na ihe ndị dị ndụ.Mgbe ìhè anyanwụ na-arụ ọrụ, TiO2 nanoparticles na-emepụta ụdị oxygen na-arụ ọrụ (ROS) nke na-eme ka oxidize na decompose organic bekee n'elu ihe.Mmetụta na-ehicha onwe ya na-enyere aka ịnọgide na-enwe ọdịdị mara mma na ịdị ọcha nke ihe owuwu ihe, na-ebelata mkpa maka ihicha na mmezi mgbe niile.

3. Ọdịnaya emelitere:

Mgbakwunye nke TiO2 nanoparticles na ihe nwere ike welie ogologo oge ya na iguzogide mmebi gburugburu ebe obibi.TiO2 na-arụ ọrụ dị ka photocatalyst nke na-akwalite mwepu nke ihe ndị na-emetọ ihe ndị na-emepụta ihe, na-ebelata nchịkọta nke mmetọ n'elu ihe.Nke a, n'aka nke ya, na-enyere aka ibelata mmetụta nke ihu igwe, ntanye, na uto microbial, na-agbatị ndụ ọrụ nke ihe owuwu nke ekpughere n'èzí.

4. Njirimara Ntugharị:

TiO2 nanoparticles nwere ike inye ihe ndị na-egbuke egbuke n'elu ihe na-egbuke egbuke, na-ebelata mmịkọ okpomọkụ ma na-ebelata mmetụta àgwàetiti okpomọkụ nke obodo.Ihe na-acha ọkụ na-acha ọkụ nwere ihe TiO2 na-egosipụta ìhè anyanwụ ma na-amịkọrọ obere okpomọkụ ma e jiri ya tụnyere ihe a na-emekarị, na-eme ka okpomọkụ dị ala ma belata oriri ume maka oyi na mpaghara obodo.Nke a na-eme ka kọmpat emegharịrị TiO2 dabara adaba maka ngwa dịka pavement, ụzọ ụzọ na pavement mepere emepe.

5. Njirimara mgbochi microbial:

E gosiputara nanoparticles TiO2 ka ha gosipụta ihe ndị na-egbochi nje, na-egbochi uto nke nje bacteria, fungi, na algae n'elu ihe.Mmetụta antimicrobial a na-enyere aka igbochi nguzobe nke biofilms, stains, na ísì n'ime ihe owuwu, karịsịa na gburugburu iru mmiri na mmiri mmiri ebe uto microbial juru ebe niile.Kọnkịta emegharịrị TiO2 nwere ike si otú a na-atụnye aka n'ịkwalite ịdị ọcha na ịdị ọcha na ntọala dịka ụlọ ọgwụ, ụlọ nyocha, na ebe a na-edozi nri.

Mmechi:

Na mmechi, Titanium dioxide (TiO2) na-eje ozi dị iche iche n'ụdị usoro, na-enye uru dị ka ọrụ photocatalytic, ihe na-ehicha onwe ya, ịdịte aka ka mma, elu na-egosipụta, na mmetụta antimicrobial.Site na itinye TiO2 nanoparticles n'ime ngwakọta kọmpụta, ndị injinia na ndị na-ese ụkpụrụ ụlọ nwere ike ịkwalite arụmọrụ, ogologo ndụ, na nkwado nke ihe owuwu ihe mgbe ha na-ekwu maka nsogbu gburugburu ebe obibi na ahụike.Ka nyocha na mmepe na nanotechnology na-aga n'ihu, a na-atụ anya na iji TiO2 na-eme ihe ga-arụ ọrụ na-arịwanye elu na ụlọ ọrụ mmepụta ihe, na-enye ihe ngwọta ọhụrụ maka akụrụngwa obodo na nkwado gburugburu ebe obibi.
