Chii chiri Kushandiswa kweTiO2 muKongiri?

Titanium dioxide (TiO2) chiwedzere chakasiyana-siyana chinowana akati wandei mashandisirwo mukongiri maumbirwo nekuda kweiyo yakasarudzika zvimiro.Mamwe mashandisirwo akajairika eTiO2 mukongiri anosanganisira:

1. Photocatalytic Chiitiko:

TiO2 inoratidzira photocatalytic chiitiko kana yakafumurwa kune ultraviolet (UV) mwenje, zvichitungamira mukushatiswa kwe organic komisheni uye zvinosvibisa pamusoro pekongiri.Ichi chivakwa chinonyanya kubatsira mukudzikisa kusvibiswa kwemhepo uye kuvandudza kunaka kwemweya munzvimbo dzemudhorobha.TiO2-ine kongiri yepamusoro inogona kubatsira kuputsa zvinosvibisa zvinofambiswa nemhepo senge nitrogen oxides (NOx) uye volatile organic compounds (VOCs), zvichibatsira munzvimbo dzakachena uye dzine hutano hwemaguta.

2. Nzvimbo dzekuzvichenesa:

TiO2 nanoparticles inosanganisirwa mukongiri inogona kugadzira yekuzvichenesa nzvimbo inodzinga tsvina, tsvina, uye organic zvinhu.Kana yaitwa nechiedza chezuva, TiO2 nanoparticles inogadzira reactive oxygen marudzi (ROS) ayo oxidize uye anoodza organic zvinhu pamusoro pekongiri.Iyi yekuzvichenesa mhedzisiro inobatsira kuchengetedza chitarisiko chekunaka uye kuchena kwekongiri zvimiro, kuderedza kudiwa kwekugara kuchenesa uye kugadzirisa.

3. Yakavandudzwa Kusimba:

Kuwedzerwa kweTiO2 nanoparticles kune kongiri kunogona kuwedzera kusimba kwayo uye kuramba kushatiswa kwezvakatipoteredza.TiO2 inoshanda se photocatalyst inokurudzira kuparara kwezvinhu zvinosvibisa zvehupenyu, kuderedza kuunganidza kusvibiswa pamusoro pekrete.Izvi, zvakare, zvinobatsira kudzikisira mhedzisiro yemamiriro ekunze, kusvibisa, uye kukura kwehutachiona, kuwedzera hupenyu hwesevhisi yezvivakwa zvekongiri zvakaratidzwa kune mamiriro ekunze.

4. Reflective Properties:

TiO2 nanoparticles inogona kupa inovhenekera zvivakwa kune kongiri nzvimbo, kuderedza kunyura kwekupisa uye kudzikisira kupisa kwemadhorobha kwechitsuwa.Kongiri ine ruvara rwakajeka ine TiO2 zvidimbu inoratidza chiedza chezuva uye inotora kupisa kushoma kana ichienzaniswa nekongiri yakajairika, zvichikonzera kudzikira kwetembiricha uye kuderedzwa kwesimba rekushandisa pakutonhodza mumaguta.Izvi zvinoita kuti TiO2-yakagadziridzwa kongiri ikwane maapplications akadai semapavement, nzira dzeparutivi, uye mapavements emudhorobha.

5. Anti-Microbial Properties:

TiO2 nanoparticles yakaratidzwa kuratidza antimicrobial properties, ichidzivisa kukura kwebhakitiriya, fungi, uye algae panzvimbo yekrete.Iyi antimicrobial effect inobatsira kudzivirira kuumbwa kwebiofilms, mavara, uye kunhuhwirira pane zvivakwa zvekongiri, kunyanya munzvimbo dzakanyorova uye dzakanyorova uko kukura kwehutachiona kwakapararira.TiO2-yakagadziridzwa kongiri inogona kubatsira mukuvandudza hutsanana uye hutsanana munzvimbo dzakaita sezvipatara, marabhoritari, uye nzvimbo dzekugadzira chikafu.

Mhedziso:

Mukupedzisa, Titanium dioxide (TiO2) inoshandisa zvinangwa zvakawanda mukugadzirwa kwekongiri, ichipa mabhenefiti akadai senge photocatalytic chiitiko, kuzvichenesa zvivakwa, kusimba kwekusimba, kutaridzika kwenzvimbo, uye antimicrobial mhedzisiro.Nekubatanidza TiO2 nanoparticles mumisanganiswa yekongiri, mainjiniya nevagadziri vanogona kusimudzira mashandiro, hupenyu hurefu, uye kusimba kwezvimiro zvekongiri vachigadzirisa nharaunda uye hutano zvinonetsa.Sezvo kutsvagisa nekusimudzira mu nanotechnology kuri kuramba kuchienderera mberi, kushandiswa kweTiO2 mukongiri kunotarisirwa kuita basa rinowedzera kukosha muindasitiri yekuvaka, ichipa zvigadziriso zvezvivakwa zvemudhorobha uye kuchengetedza kwezvakatipoteredza.
