Lub luag haujlwm ntawm calcium carbonate hauv cov xim pleev xim:
Raws li lub cev xim, nws muaj qhov ua haujlwm, ua rau nws qab, txawm tias thiab siab dawb.
Muaj qee qhov qhuav npog fais fab, cov khoom lag luam zoo nkauj feem ntau siv. Thaum lub particle qhov loj ntawm titanium dioxide nyob ze rau ntawm titanium dioxide, cov nyhuv npog ntawm titanium dioxide tuaj yeem hloov kho.
Muaj peev xwm txhim kho lub zog ntawm zaj duab xis, dej tsis kam, qhuav, txhuam tsis kam.
Txo tus nqi thiab siv 10% -50%.
Piv txwv li, cov superfine hnyav calcium carbonate hmoov cov khoom siv muaj qhov pom tseeb ntawm lub sijhawm luv luv ntawm kev tawg sanding nyob rau hauv cov txheej txheem ntawm cov xim ua xim yas ntau lawm, txhim kho qhov zais lub zog, txhim kho qhov viscosity ntawm latex, txo cov nqi ntawm titanium dawb hmoov thiab txhim kho polishing. kev kawm ntawm putty.
Hauv kev tsim cov txheej xim, cov xim ua kom zoo emulsion xim siv superfine calcium carbonate, qib qis emulsioni xim xaiv ntawm cov coarse sib piv me me, cov roj qis nqus cov nqi ntawm cov calcium hnyav.
Thaum tam sim no, daim ntawv thov nyhuv ntawm hnyav calcium carbonate hmoov nyob rau sab hauv phab ntsa latex xim yog zoo dua, nws cov particle loj tswj d97< 10="" m,="" d50="" txog="" 1.5="" m,="" whiteness=""> 95%, CaCO3≥98%.
PUDACalcium carbonate ntim tshuab:
Calcium carbonate yog siv ntau xim nyob hauv cov xim pleev xim, uas ua lub luag haujlwm ntawm txhawm rau thav duab thiab cov hauv qab hauv cov xim tha xim thiab txhim kho kev ua tau zoo ntawm cov xim muaj hlau.
Hauv cov hmoov putty, 70-80% yog cov calcium uas hnyav.
Hauv cov xim tuab, calcium carbonate ntau npaum feem ntau saum 30%;
Hauv cov pa luam dej muaj txheej txheem, cov ntsiab lus calcium carbonate yog 20-60%;
Calcium carbonate yog qhov zoo tagnrho matting muab cov xim pleev xim rau qhov ua tiav. Piv txwv, matte dawb casework phab ntsa xim muaj 11.5% calcium calcium carbonate.
Hauv cov xim hlau antirust txheej, calcium carbonate muaj qee yam antirust nyhuv, qhov tsim nyog yog kwv yees li 30%;
Feem ntau, 16% -20% ntawm lub teeb calcium carbonate muaj nyob hauv cov tshuaj pleev xim polyvinyl xws li 106 thiab 803.
Sab hauv tiav, xws li polyvinylidene emulsion xim, feem ntau muaj kwv yees li 10% calcium carbonate.
