Nyob rau hauv lub ntiaj teb no ntawm paintings thiab coatings,titanium dioxideCov xim dawb yog ib qho tseem ceeb muaj txiaj ntsig ntev ntev rau nws cov khoom tshwj xeeb. Raws li cov khoom siv dav siv, titanium dioxide ua lub luag haujlwm tseem ceeb hauv kev muab cov opacity, ci ntsa iab thiab kav ntev uas yuav tsum tau ua rau cov xim zoo nkauj thiab cov txheej txheem. Hauv qhov blog no, peb yuav ua tib zoo saib qhov tseem ceeb ntawm titanium dioxide dawb pigment hauv kev lag luam tha xim thiab yuav ua li cas nws tau txais nws lub koob npe nrov raws li cov khoom tseem ceeb hauv kev ua tiav qhov pom kev pom thiab ua tiav ntev.
TiO 2, tseem hu ua titanium dioxide, yog ib txwm tshwm sim titanium oxide nrog cov tshuaj formula TiO2. Nws yog khoom plig rau nws qhov tshwj xeeb whiteness, ci ntsa iab thiab siab refractive index, tso cai rau nws kom zoo tawg thiab cuam tshuam lub teeb. Cov khoom no ua rau TiO2 cov xim zoo tshaj plaws kom ua tiav cov xim dawb, opaque dawb xav tau rau ntau yam kev siv, suav nrog kev tsim vaj tsev, tsheb thiab cov txheej txheem. Nws muaj lub zog zais zoo heev thiab khaws cov xim, ua rau nws yog thawj qhov kev xaiv kom ua tiav ib qho kev sib tw, kav ntev.
Ib lub luag haujlwm tseem ceeb tshaj plaws ntawmTiO2 dawb pigmentnyob rau hauv cov xim thiab coatings yog nws muaj peev xwm muab opacity. Qhov opacity ntawm cov xim yog hais txog nws lub peev xwm los npog qhov chaw hauv qab thiab zais txhua qhov tsis zoo lossis xim dhau los. TiO2 pigments ua tau zoo nyob rau hauv cheeb tsam no vim tias lawv thaiv cov xim ntawm cov substrate thiab muab cov khoom, txawm tias lub hauv paus rau cov xim xim uas xav tau. Qhov no tsis tsuas yog txhim kho tag nrho cov tsos ntawm cov pleev xim rau saum npoo, tab sis nws kuj tseem pab txhim kho cov xim tsis kam rau huab cua thiab UV degradation.
Ntxiv nrog rau nws cov opacity, titanium dioxide dawb pigments ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov xim thiab cov xim. Nws lub siab refractive Performance index tso cai rau lub teeb tawg ntau tshaj plaws, pab txo qhov nqus ntawm UV rays uas tuaj yeem ua rau xim degradation thiab fading. Qhov no nyob rau hauv lem contributes rau lub sij hawm ntev xim tuav thiab kev tiv thaiv ntawm cov xim nto. Tsis tas li ntawd, TiO2's chemical stability thiab tsis kam mus rau acids, alkalis thiab lwm yam ib puag ncig ua rau nws ib tug indispensable muaj nyob rau hauv tau txais coatings nrog zoo heev huab cua tsis kam thiab thiav.
Lub versatility ntawm titanium dioxide dawb pigment extends tshaj nws siv nyob rau hauv cov xim thiab coatings. Nws kuj yog siv dav hauv cov yas, inks thiab lwm yam kev siv uas xav tau xim dawb, opacity thiab UV tsis kam. Nws lub peev xwm los txhim kho qhov pom kev pom thiab kev ua haujlwm ntev ntawm ntau yam khoom ua rau nws muaj txiaj ntsig zoo rau kev lag luam uas tseem ceeb tshaj qhov zoo thiab kev ua haujlwm.
Hauv cov ntsiab lus, titanium dioxide dawb pigments ua lub luag haujlwm tseem ceeb hauv kev lag luam tha xim los ntawm kev muab cov opacity tsis sib xws, ci ntsa iab thiab kav ntev rau cov xim thiab txheej. Nws cov khoom tshwj xeeb ua rau nws yog ib qho khoom tseem ceeb rau kev ua tiav qhov pom kev zoo nkauj thiab ua tiav ntev ntev hauv ntau yam kev siv. Raws li qhov kev thov rau cov xim zoo nkauj thiab cov coatings txuas ntxiv mus, qhov tseem ceeb ntawm titanium dioxide dawb pigments hauv kev tswj thiab txhim kho cov khoom zoo tsis tuaj yeem overstated.
