Kev xaiv ntawm cov pigments rau hmoov txheej

Kev siv cov pigments hauv cov hmoov txheej tsuas yog ua lub luag haujlwm ntawm cov xim tha xim thiab kho kom zoo nkauj. Feem ntau siv yog inorganic pigments thiab organic pigments. Inorganic pigments muaj cov yam ntxwv ntawm cov nqi qis, zoo lub teeb thiab huab cua tsis kam, zoo thaum tshav kub kub tiv thaiv, muaj zog zais zog, thiab cov hue ruaj khov, tab sis lawv qis me ntsis mus rau cov organic pigments nyob rau hauv cov nqe lus ntawm kev pom tseeb ntawm cov hue; cov organic xim muaj xim tshiab. Kev ci ntsa iab, dav dav kho tau zoo dua ntawm cov hue, siab tinting lub zog, thiab lwm yam Txawm li cas los xij, cov xim pigments feem ntau muaj qhov tsis zoo xws li tus nqi siab dua, tsis kam tiv tshav kub tsis zoo, tsis tshua muaj lub teeb thiab huab cua tsis kam, thiab lub zog tsis zoo. Yog li, inorganic pigments muaj qee yam zoo hauv kev siv hmoov txheej. Ntawm cov xim inorganic, qee hom xim muaj tshuaj lom (xws li cov muaj cadmium, chromium, thiab txhuas). Yog li ntawv, hlau oxide pigments, raws li ib txwm muaj rau ib puag ncig uas tsis muaj tshuaj lom cov xim, tau dhau los ua kev xaiv thawj cov hmoov txheej. Ntxiv rau, cov hlau oxide pigments kuj tseem muaj cov yam ntxwv ntawm kev muaj txiaj ntsig tag nrho thiab ntau qhov kho kom haum cov xim.
