Metallic pigments yog ib chav kawm ntawm cov xim uas muaj xim hlau. Lawv cov khoom tseem ceeb feem ntau yog cov khoom hlau, xws li tooj liab, zinc, thiab txhuas, ua tiav rau hauv cov hmoov los yog flake lug ntawm cov txheej txheem tshwj xeeb. Cov xim no tsim cov xim hlau los ntawm kev xav txog lub teeb thiab yog siv dav hauv kev kho kom zoo nkauj, luam ntawv, thiab txheej. Lawv cov yam ntxwv muaj xws li lub zog zais siab, muaj zog tiv thaiv huab cua, thiab xim tunability, ua tau raws li qhov xav tau ntawm ntau yam xwm txheej rau cov xim hlau zoo nkauj.
Siv tooj liab-kub hmoov ua piv txwv. Nws yog qhov tseem ceeb ntawm tooj liab-zinc alloy particles nrog qhov loj me txog li 1200 mesh, nthuav tawm raws li golden- daj hmoov. Cov xim no, thaum sib xyaw nrog cov roj kub lossis cov kua roj vanish, tuaj yeem ua rau cov xim kub zoo nkauj lossis tus cwj mem, feem ntau siv rau hauv cov ntim sab nrauv xws li cov thawv luam yeeb thiab cov ntawv cim lub raj mis uas xav tau kev ntxhib los mos. Nws cov txheej txheem tsis muaj xws li cov ntsiab lus dej tsawg dua lossis sib npaug li 0.15%, cov kuab tshuaj organic-soluble teeb meem tsawg dua lossis sib npaug li 6.0%, thiab cov khoom siv sieve (45μm sieve aperture) Tsawg dua lossis sib npaug li 1.0%. Cov ntsuas no ua kom muaj kev ruaj ntseg thiab dispersibility ntawm cov xim, tsis txhob muaj teeb meem xws li particle tsim los yog tsis sib xws gloss nyob rau hauv txheej vim impurities los yog ya raws. Ntawm daim ntawv thov, cov xim hlau yuav tsum raug xaiv raws li qhov tshwj xeeb daim ntawv thov scenario. Piv txwv li, kev tshuaj ntsuam luam ntawv yuav tsum muaj cov xim zoo nkauj kom tsis txhob txhaws qhov screen, thaum kho kom zoo nkauj hauv vaj tsev yuav ua rau cov xim xim huab cua tsis kam. Copper-kub hmoov muaj lub neej txee ntev txog 36 lub hlis thiab tau dhau CCC daim ntawv pov thawj zoo, qhia tias nws ua tau raws li kev lag luam yuav tsum tau ua kom ntev - khaws cia thiab kev nyab xeeb. Tsis tas li ntawd, nws cov xim txheej yuav tsum muaj "zoo golden metallic luster, cov khoom zoo nkauj, thiab smoothness," ua rau nws muaj txiaj ntsig zoo rau cov txheej txheem kub plating hauv crafts, hlau sculptures, thiab lwm yam.
Los ntawm txoj kev xav, lub luster ntawm cov xim hlau yog tsim los ntawm kev xav ntawm lub teeb los ntawm microparticles. Thaum cov particle loj nyob ze rau lub wavelength ntawm pom lub teeb (feem ntau yog 1-100μm), qhov kev xav tau siab tshaj plaws, tsim kom muaj qhov tshwj xeeb shimmering nyhuv ntawm hlau. Lub uniformity ntawm particle loj faib ncaj qha cuam tshuam lub gloss uniformity ntawm txheej, uas yog vim li cas cov ntsiab lus ntawm kev tshuaj ntsuam cov ntaub ntawv nyob rau hauv tooj liab-kub hmoov yuav tsum nruj me ntsis tswj. Hais txog kev phooj ywg ib puag ncig, cov xim hlau niaj hnub no maj mam ua raws li cov qauv thoob ntiaj teb ib puag ncig xws li RoHS los ntawm kev txo cov ntsiab lus ntawm cov hlau hnyav (xws li txhuas thiab mercury) thiab txhim kho cov kuab tshuaj, nthuav lawv cov ntawv thov hauv thaj chaw rhiab heev xws li ntim khoom noj.
