Lithopone thiab titanium dioxideyog ob lub pigments dav siv nyob rau hauv ntau yam lag luam, nrog rau cov xim, yas thiab ntawv. Ob qho pigments muaj cov khoom tshwj xeeb uas ua rau lawv muaj txiaj ntsig hauv kev tsim cov xim. Hauv tsab xov xwm no, peb yuav tshawb txog qhov zoo ntawm lithopone thiab titanium dioxide thiab lawv cov kev siv hauv kev lag luam sib txawv.
Lithopone yog cov xim dawb uas tsim los ntawm kev sib xyaw ntawm barium sulfate thiab zinc sulfide. Nws yog lub npe hu rau nws zoo heev nkaum hwj chim thiab huab cua tsis kam, ua rau nws yog ib tug nrov kev xaiv rau kev siv sab nraum zoov. Tsis tas li ntawd, lithopone yog tus nqi tsim nyog, ua rau nws yog qhov kev xaiv zoo nkauj rau cov tuam txhab nrhiav kom txo cov nqi tsim khoom yam tsis muaj kev cuam tshuam zoo. Kev siv lithopone hauv kev tsim cov xim thiab cov txheej txheem muab kev tiv thaiv zoo thiab ua haujlwm ntev, ua rau nws tsim nyog rau sab nrauv, kev lag luam thiab marine txheej.
Lithopone muaj cov ntawv thov dhau ntawm kev lag luam coatings. Nws kuj yog siv rau hauv kev tsim cov yas, roj hmab thiab ntawv. Hauv cov yas, lithopone yog siv los faib cov opacity thiab ci ntsa iab rau cov khoom kawg. Hauv kev tsim roj hmab, lithopone tau ntxiv rau cov roj hmab sib txuas los txhim kho lawv cov huab cua thiab kev laus tiv thaiv. Nyob rau hauv daim ntawv kev lag luam, lithopone yog siv los ua ib tug muab tub lim kom lub brightness thiab opacity ntawm daim ntawv cov khoom.
Titanium dioxideyog lwm cov xim siv dav uas muaj ntau yam zoo hauv cov xim ntau lawm. Nws paub txog nws qhov tshwj xeeb dawb thiab ci ntsa iab, ua rau nws yog qhov kev xaiv nrov rau cov ntawv thov uas xav tau siab opacity thiab xim tuav. Titanium dioxide feem ntau yog siv los tsim cov xim, coatings, plastics thiab inks. Nws muaj peev xwm ua tau zoo diffuse lub teeb ua rau nws zoo tagnrho rau kev ua tiav cov xim vibrant, ntev ntev hauv ntau yam khoom.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm titanium dioxide yog nws cov UV tsis kam, ua rau nws tsim nyog rau kev siv sab nraum zoov. Hauv kev lag luam pleev xim thiab coatings, titanium dioxide yog siv los tiv thaiv UV hluav taws xob thiab tiv thaiv kev degradation ntawm cov hauv qab substrate. Qhov no ua rau nws yog ib qho tseem ceeb nyob rau hauv formulations rau sab nrauv xim, automotive coatings thiab tiv thaiv txheej rau industrial cov khoom.
Ntxiv nrog rau kev siv tshuaj pleev xim thiab txheej txheej, titanium dioxide kuj tseem siv los tsim cov yas thiab inks. Hauv cov yas, nws muab opacity thiab ci ntsa iab, txhim kho qhov pom kev pom ntawm cov khoom kawg. Hauv kev lag luam number case, titanium dioxide yog siv los ua kom tiav cov xim zoo nkauj thiab ntev ntev hauv kev luam ntawv.
Thaum ua ke,lithoponethiab titanium dioxide muaj ntau yam zoo hauv cov xim ntau lawm. Lawv cov khoom ntxiv ua rau lawv haum rau ntau yam kev siv, los ntawm cov xim sab nrauv thiab cov txheej txheem rau cov khoom yas thiab ntawv. Siv cov xim no tso cai rau cov tuam txhab lag luam kom ua tiav cov xim xav tau, opacity thiab durability hauv lawv cov khoom thaum tseem tshuav nqi.
Nyob rau hauv luv luv, cov txiaj ntsig ntawm lithopone thiab titanium dioxide hauv pigment ntau lawm yog qhov tseem ceeb. Lawv cov khoom tshwj xeeb ua rau lawv muaj txiaj ntsig zoo hauv ntau qhov kev lag luam, muab cov khoom tseem ceeb xws li opacity, ci ntsa iab, huab cua tsis kam thiab tiv thaiv UV. Raws li kev thov rau cov xim zoo nkauj txuas ntxiv mus, covsiv lithoponethiab titanium dioxide tseem tseem ceeb heev kom ua tau raws li qhov xav tau ntau yam ntawm kev tsim khoom lag luam.
