Kev loj hlob sai ntawm kev lag luam inorganic xim
Nrog kev rov qab ntawm kev lag luam thoob ntiaj teb, kev tsim kho hauv tsev thiab txawv teb chaws, xim, plastics, inks thiab lwm yam kev lag luam tau pom kev loj hlob sai, qhov kev thov rau cov inorganic pigments kuj tau nce sai. Nrog txoj kev loj hlob sai ntawm txheej kev lag luam, raws li ib qho ntawm nws cov khoom siv nyoos inorganic pigments tau tsim los ntawm leaps thiab ciam teb, ntawm uas titanium dioxide, hlau oxide lees paub rau kev faib ua feem ntau.
Cov tib neeg tau siv cov tshuaj pleev xim inorganic thaum ntxov, thiab lub sijhawm ua luam yeeb ua ntej lub ntsej muag dub, chalk, chroma, thiab natural iron oxide tau siv los ua cov xim. Hauv 3000 BC mus txog 2000 BC, txoj kev tsim cov hmoov txhuas dawb tau ua tiav. Nyob ib ncig ntawm {{2}} BC, Suav siv kev txhim kho hluav taws xob Hg Zhu (HgS) ua xim. Hauv 1704, Disbach, Lub teb chaws Yelemees, tau tsim cov xim xim Prussia xiav (xim tsaus xim xiav, lub ntsiab lus tseem ceeb ntawm Fe 4 (Fe) 6 3 xH 2 O kev tsim qauv. Hauv { {7}}, Fabkis L.-N. Volkeran ua chrome daj, hauv 1831 Fabkis IB Gimey cog ze Lyon tsim cov pawg ntsuab, hauv xyoo 187 4 Lub Tuam Txhab British ntawm Auschwitz Zinc White lub tuam txhab yog Widnes cog tsim cov xim zinc birch dawb. Hauv 1916, cov xaj dawb titanium (suav nrog TiO 2 2 5%), 19 2 3 ntshiab titanium dioxide (titanium dioxide) rau hauv kev tsim khoom , thiaj li hais tias qib cov xim muaj ntau lawm tau ua ib kauj ruam loj dua.Qhov tam sim no, inorganic xim chromatography, cia li ua tiav.
Cov tshuaj pleev xim inorganic feem ntau tiv taus qhov kub thiab txias, lub siab tawv, huab cua-huab cua, kev tiv thaiv corrosion, feem ntau ntawm cov ntsuas kev ua tau zoo ntau dua li cov xim pleev xim organic, thiab ib puag ncig tus phooj ywg zoo, tab sis feem ntau ntawm cov txheej yuav xav tau kub, ultra-siab kub, xim hom tsis nplua nuj, cov nyhuv nto tsis zoo, loj heev txwv nws siv. Ntxiv rau kev yooj yim txheej, organic txheej softens, tab sis kuj muaj qhov zoo ntawm zoo toughness, nplua nuj xim, kho kom zoo nkauj zoo, muaj zog siv rau substrates thiab li ntawm. Nws tuaj yeem pom tias qhov zoo ntawm cov pleev xim inorganic feem ntau yog qhov zoo ntawm cov organic coatings, organic txheej txheej tseem yog cov tsis muaj zog ntawm cov txheej txheem ua kom muaj ntxig, thiab qhov tshwm sim ntawm cov plooj (veneers) txheej txheej, kom qhov zoo ntawm ob qho kev sib xyaw ua ke.
