Titanium dioxide inowanzoitika titanium oxide iyo yakawana kutarisisa kwakapararira nekuda kwehuwandu hwayo hwekushandisa mumaindasitiri akasiyana. Kubva pamucheka wezuva kusvika kupende, ruvara rwechikafu kuenda kufotocatalyst, titanium dioxide musanganiswa unoshanda unokwereta zvimiro zvayo kuchimiro chayo chakasiyana. Mune ino blog, isu tichanyatso tarisisa iyochimiro chetitanium dioxideuye ongorora kuti inofambisa sei kushandiswa kwayo kwakawanda.
Pakati pemwoyo wekusiyana-siyana kwetitanium dioxide pane chimiro chayo chekristaro. Titanium dioxide iripo mumhando nhatu huru dzecrystalline: rutile, anatase, uye brookite. Pakati peizvi, rutile uye anatase ndiwo anonyanya kuzivikanwa mafomu, imwe neimwe iine hurongwa hwayo hweatomu.
Rutile ndiyo yakagadzikana uye yakawanda fomu yetitanium dioxideuye inoratidzwa nedense lattice chimiro. Kurongeka kwetitanium uye maatomu eokisijeni murutile inoguma neiyo yakakwira refractive index, ichiita iyo yakanakira UV sefa mune pigment, machira uye kunyange sunscreen. Rutile's close-packed chimiro zvakare inobatsira mukugadzikana kwayo kwemakemikari, ichiita kuti ive yakakodzera kune corrosion-resistant material applications.
Anatase, kune rumwe rutivi, ine yakavhurika uye isina dense chimiro uye inoratidza zvakasiyana zvivakwa zvichienzaniswa nerutile. Inozivikanwa neayo emhando yephotocatalytic chiitiko, anatase yakawana maapplication munzvimbo dzakadai sekugadzirisa kwezvakatipoteredza, kuzvichenesa nzvimbo, uye kunyangwe kugadzirwa kwehydrogen kuburikidza nekutsemuka kwemvura. Iyo yakasarudzika kurongeka kweatomu muanatase inogonesa kugadzirwa kwakanaka kwema electron-hole pairs kana yaiswa pachiedza, ichipa kugona kwephotocatalytic.
Kugona kweTitanium dioxide kuvapo mumhando dzakasiyana-siyana dze nanostructures inowedzera kuwedzera kushanda kwayo. Nanoscale titanium dioxide ine nzvimbo yakakwira kusvika kuvhoriyamu reshiyo uye inoratidza inosimudzira reactivity uye chiedza kuparadzira zvivakwa, zvichiita kuti ive yakakosha mumashandisirwo akadai sephotovoltaics, sensors uye antimicrobial coatings. Iko kugona kugadzirisa titanium dioxide nanostructures inovhura nzira nyowani dzekushandisa kwayo muhunyanzvi hwepamberi.
Kunzwisisa chimiro chetitanium dioxide kwakakosha pakugadzirisa mashandiro ayo kune chaiwo maapplication. Nekudzora fomu rekristaro, saizi yechikamu uye zvivakwa zvepasi, vaongorori uye mainjiniya vanogona kukwenenzverazvinhu zve titanium dioxidekuzadzisa zvinodiwa nemaindasitiri akasiyana. Kunyangwe ichikwidziridza kugona kwayo kweUV-kuvharira mukugadzirwa kwezuva kana kusimudzira chiitiko chayo chefotocatalytic kugadzirisa nharaunda, chimiro chetitanium dioxide ipurani yekushanda kwayo kwakasiyana-siyana.
Muchidimbu, chimiro chetitanium dioxide, kusanganisira chimiro chayo checrystalline uye nanostructure, inosimbisa kushandiswa kwayo kunoshamisa uye kushandiswa mumaindasitiri akasiyana-siyana. Nekuburitsa chimiro chayo chakaomarara, masayendisiti nevagadziri vanoenderera mberi nekuvhura kugona kwakazara kwetitanium dioxide, vachigadzira nzira yezvitsva zvekushandisa uye mhinduro dzinogara dziripo. Sezvo isu tichiongorora zvakadzama mukati mechimiro-chivakwa hukama hwetitanium dioxide, tinogona kutarisira kuona imwe budiriro mukushandisa kwayo yakasarudzika zvivakwa kubatsira nzanga uye nharaunda.
