Titanium dioxide, nke a na-akpọkarị TiO2, bụ pigmenti dị iche iche ejiri na ụlọ ọrụ dị iche iche. A maara ya maka ihe ọkụkụ ọkụ ọkụ ya dị mma, ihe nrịbama dị elu na nchebe UV. Enwere ụdị TiO2 dị iche iche, nke ọ bụla nwere akụrụngwa na ngwa pụrụ iche. Na blọọgụ a, anyị ga-enyocha ụdị titanium dioxide dị iche iche na ojiji ha na-arụ n'ụlọ ọrụ dị iche iche.
1. Rutile TiO2:
Titanium dioxide rutilebụ otu n'ime ụdị titanium dioxide a na-ejikarị eme ihe. A maara ya maka nnukwu refractive index, nke na-eme ka ọ dị mma maka ngwa ndị chọrọ nnukwu opacity na nchapụta. A na-eji Rutile titanium dioxide mee ihe n'ọtụtụ ebe na mmepụta nke agba, mkpuchi, plastik na akwụkwọ, na ezigbo ọkụ ọkụ ya nwere ike imeziwanye ọcha na nchapụta nke ngwaahịa ikpeazụ.
2. Anatase titanium dioxide:
Anatase titanium dioxide bụ ụdị ọzọ dị mkpa nke titanium dioxide. A na-eji ya dị elu na mpaghara fotocatalytic. A na-ejikarị Anatase TiO2 na-emepụta ihe mkpuchi fotocatalytic, ihe na-ehicha onwe ya na ngwa ngbanwe gburugburu ebe obibi. Ikike ya ime ka mbelata nke ogige organic n'okpuru ìhè UV na-eme ka ọ bụrụ ihe bara uru maka usoro ikuku na mmiri.
3. Nano titanium dioxide:
Nano-TiO2, nke a na-akpọkwa nanoscale titanium dioxide, bụ ụdị TiO2 nwere nha nha n'ogo nanometer. Ụdị ultrafine a nke TiO2 emeela ka ọrụ fotocatalytic dịkwuo elu, ebe dị elu na ihe ọkụkụ dị mma. Nanoscale titanium dioxide nwere ngwa ngwa dị iche iche, gụnyere usoro ihe mkpuchi anwụ, ihe ịchọ mma, mkpuchi gburugburu ebe obibi na ihe na-egbu egbu. Obere urughuru ya na-enye mkpuchi na nchebe ka mma na mkpuchi sunscreen na mkpuchi mgbochi UV.
4. titanium dioxide mkpuchi:
mkpuchi TiO2 na-ezo aka na mkpuchi ihe mkpuchi titanium dioxide na ihe inorganic ma ọ bụ organic iji melite mgbasa ha, nkwụsi ike na ndakọrịta na matrices dị iche iche. A na-ejikarị TiO2 kpuchie ya na mmepụta nke mkpuchi dị elu, inks na plastik, ebe mgbasa ozi nke TiO2 dị oke mkpa iji nweta ihe ndị a chọrọ dị ka ogologo oge, nkwụsị ihu igwe na nkwụsi ike agba.
Na nchịkọta, dị iche icheụdị TiO2nwere ọtụtụ ihe onwunwe na ngwa n'ofe ụlọ ọrụ. Site na imeziwanye ọcha nke agba na mkpuchi iji nye nchebe UV na sunscreens iji meziwanye ikuku na mmiri site na photocatalysis, titanium dioxide na-arụ ọrụ dị mkpa n'ọtụtụ ngwaahịa na teknụzụ. Ka nyocha na mmepe nanotechnology na-aga n'ihu, anyị nwere ike ịtụ anya ịhụ ihe ọhụrụ na ngwa maka titanium dioxide n'ọdịnihu.
