Coloring pigments yog cov ntaub ntawv tseem ceeb tshaj plaws hauv tinting technology, thiab lawv cov khoom yuav tsum tau nkag siab zoo thiab siv tau yooj yim, kom cov xim zoo, tus nqi qis thiab sib tw tuaj yeem tsim.
Feem ntau siv pigments rau cov xim yas sib xws muaj xws li cov xim tsis muaj organic, cov xim organic, hnyav dyes, hlau xim, pearlescent pigments, magic pearlescent pigments, fluorescent pigments thiab whitening pigments.Hauv cov ntaub ntawv saum toj no, peb yuav tsum ua kom pom tseeb tias muaj qhov sib txawv ntawm cov pigments thiab dyes: pigments tsis soluble nyob rau hauv dej los yog nyob rau hauv nruab nrab siv, thiab yog ib chav kawm ntawm cov xim uas muaj xim rau coloring teeb meem nyob rau hauv lub xeev ntawm heev. dispersed hais.Pigments thiab organic pigments.Cov dyes yog soluble hauv dej thiab cov kuab tshuaj organic, thiab tuaj yeem ua ke nrog cov khoom siv dyed los ntawm qee yam tshuaj lom neeg.Qhov zoo ntawm density yog tsawg tinting lub zog thiab zoo molecular yog me me, thiab tsiv teb tsaws yog yooj yim rau thaum muaj xim.
Inorganic Pigments: Inorganic pigments feem ntau cais los ntawm txoj kev tsim khoom, kev ua haujlwm, cov qauv tshuaj, thiab xim.Raws li txoj kev tsim khoom, nws tau muab faib ua ob pawg: ntuj pigments (xws li cinnabar, verdigris thiab lwm yam ntxhia pigments) thiab cov xim hluavtaws (xws li titanium dioxide, hlau liab, thiab lwm yam).Raws li kev ua haujlwm, nws tau muab faib ua cov xim xim, cov xim pleev xim, cov xim tshwj xeeb (xws li cov xim kub kub, pearlescent pigments, fluorescent pigments), thiab lwm yam Acids, thiab lwm yam. Raws li cov qauv tshuaj, nws muab faib ua hlau. series, chromium series, lead series, zinc series, hlau series, phosphate series, molybdate series, thiab lwm yam. lwm .;dub series pigments: carbon dub, hlau oxide dub, thiab lwm yam .;daj series pigments: chrome daj, hlau oxide daj, cadmium daj, titanium daj, thiab lwm yam;
Organic Pigments: Organic pigments muab faib ua ob pawg: ntuj thiab hluavtaws.Niaj hnub no, hluavtaws organic pigments feem ntau siv.Synthetic organic pigments tuaj yeem muab faib ua ntau pawg xws li monoazo, disazo, pas dej, phthalocyanine thiab fused nplhaib pigments.Qhov zoo ntawm cov organic pigments yog siab tinting lub zog, ci xim, ua tiav xim spectrum thiab tsawg toxicity.Qhov tsis zoo yog tias lub teeb tsis kam, kub tsis kam, huab cua tsis kam, hnyav ua haujlwm thiab zais lub zog ntawm cov khoom tsis zoo li cov xim inorganic.
Solvent Dyes: Solvent dyes yog cov tebchaw uas nqus, xa tawm (cov dyes yog pob tshab) qee qhov wavelengths ntawm lub teeb thiab tsis cuam tshuam lwm tus.Raws li nws cov solubility hauv cov kuab tshuaj sib txawv, nws feem ntau muab faib ua ob pawg: ib qho yog cawv-soluble dyes, thiab lwm yam yog roj-soluble dyes.Cov kuab tshuaj dyes yog tus cwj pwm los ntawm lub zog siab tinting, ci xim thiab muaj zog luster.Lawv tsuas yog siv rau cov xim ntawm styrene thiab polyester polyether yas khoom, thiab feem ntau tsis siv rau cov xim ntawm polyolefin resins.Lub ntsiab ntau yam yog raws li nram no.Anthraaldehyde hom kuab tshuaj dyes: xws li C.1.Solvent Yellow 52#, 147#, Solvent Red 111#, Disperse Liab 60#, Solvent Violet 36#, Solvent Blue 45#, 97#;Heterocyclic hnyav dyes: xws li C .1.Solvent Orange 60 #, Solvent Red 135#, Solvent Yellow 160: 1, thiab lwm yam.
