Hauv kev tshawb fawb ntawm cov ntaub ntawv tshawb fawb, titanium dioxide (TiO2) yog cov khoom siv dav siv nrog peb lub ntsiab siv lead ua: anatase, rutile thiab brookite. Txhua daim ntawv muaj cov khoom tshwj xeeb uas ua rau nws tsim nyog rau ntau hom kev lag luam. Ntawm lawv, rutile titanium dioxide tau nyiam ntau yam xim, tshwj xeeb tshaj yog nyob rau hauv kev lag luam luam ntawv, qhov twg nws cov khoom tuaj yeem cuam tshuam rau qhov zoo thiab ruaj khov ntawm cov ntaub ntawv luam tawm.
Rutile yog feem ntau ruaj khov thiab ntau daim ntawv ntawm titanium dioxide, nrog lub siab refractive index thiab zoo heev opacity. Cov khoom no ua rau nws zoo tagnrho cov xim rau luam ntawv inks vim nws tuaj yeem txhim kho xim ci ntsa iab thiab muab kev pabcuam zoo heev. KWR-659 is KWR'srutile titanium dioxidetsim los ntawm cov txheej txheem sulfuric acid, qhia txog kev lag luam tseem ceeb ntawm daim ntawv no. Tsim tshwj xeeb rau kev lag luam luam number case, KWR-659 muab kev ua tau zoo tshaj plaws hauv ntau hom kev siv, ua kom cov ntaub ntawv luam tawm tsis yog tsuas yog zoo li vibrant, tab sis kuj sawv ntsug ntawm lub sijhawm.
Rutile's morphology ua rau nws ua tau zoo heev hauv kev luam ntawv inks. Nws koob zoo li siv lead ua qauv tso cai rau kom zoo dua dispersion nyob rau hauv cov kua xov xwm, uas ua rau kev txhim kho ntws thiab daim ntawv thov zog. Qhov no yog ib qho tseem ceeb tshwj xeeb thaum lub sij hawm luam ntawv, qhov sib xws thiab qhov zoo yog qhov tseem ceeb. KWR-659's formulation kom ntseeg tau tias nws ua tau raws li cov kev cai nruj ntawm kev lag luam luam ntawv, muab cov kev daws teeb meem zoo rau cov tuam txhab nrhiav cov inks zoo.
Piv txwv li,rutile anatase thiab brookite, thaum tseem cov ntaub ntawv ntawm titanium dioxide, muaj cov khoom sib txawv uas yuav txwv tsis pub lawv siv hauv qee yam kev siv. Piv txwv li, anatase paub txog nws cov khoom siv photocatalytic, ua rau nws tsim nyog rau kev siv hauv kev kho ib puag ncig thiab kev tu tus kheej. Txawm li cas los xij, nws qhov kev ruaj ntseg qis dua piv rau rutile tuaj yeem ua rau muaj teeb meem hauv kev siv mus sij hawm ntev, xws li luam ntawv inks, qhov ntev yog qhov tseem ceeb. Brookite yog daim ntawv tsawg tshaj plaws, feem ntau cuam tshuam los ntawm nws cov kwv tij txheeb ze thiab tsis tshua siv hauv kev lag luam.
KWR-659 yog ib lub tuam txhab ua lag luam hauv kev tsim cov sulfuric acid titanium dioxide, siv cov txheej txheem kev siv tshuab thiab cov khoom siv thawj zaug los tsim cov khoom zoo xws li KWR-659. Lub tuam txhab kev cog lus rau cov khoom zoo thiab kev tiv thaiv ib puag ncig yog cuam tshuam rau hauv nws cov txheej txheem tsim khoom, uas yog qhov tseem ceeb ntawm kev ruaj ntseg yam tsis muaj kev cuam tshuam kev ua haujlwm. Qhov kev mob siab no tsis tsuas yog ua rau KWR-659 ua tus thawj coj hauv kev lag luam, tab sis kuj ua tau raws li qhov kev thov loj hlob rau cov khoom lag luam zoo hauv kev lag luam luam ntawv.
Kev lag luam tseem ceeb ntawm titanium dioxide, tshwj xeeb tshaj yog rutile titanium dioxide, tsis tuaj yeem kwv yees. Raws li kev lag luam txuas ntxiv txhim kho, qhov kev thov rau cov khoom siv ua haujlwm siab uas ua tau raws li cov qauv nruj nruj yuav tsuas nce ntxiv. KWR-659 qhia txog lub peev xwm ntawm rutile titanium dioxide los txhim kho cov ntawv luam ntawv zoo, muab cov tuam txhab tsim kev ntseeg siab thiab siv tau zoo.
Hauv cov ntsiab lus, kev nkag siab txog morphologies ntawm anatase, rutile, thiab brookite yog qhov tseem ceeb rau kev nkag siab txog lawv qhov tseem ceeb ntawm kev lag luam. Rutile plays lub luag haujlwm tseem ceeb hauv kev lag luam luam ntawv vim nws cov khoom zoo, thiab cov khoom xws li KWR-659 los ntawm KW yog cov piv txwv ntawm kev nce qib hauv daim teb no. Raws li peb txav mus los, kev tshawb nrhiav txuas ntxiv ntawm lub peev xwm ntawm titanium dioxide yuav ua rau muaj kev hloov pauv ntxiv thiab kev txhim kho hauv ntau yam kev lag luam.
