Cov ntaub ntawv yas ntim khoom los ntawm kev hloov cov khoom siv tau ua ib qhov tseeb, yas ntim los ntawm qhov zoo, xim, sealing thiab lwm yam tseem niaj hnub txhim kho, thiab cov yas ntim ntawm tus nab npawb ntawm tus phooj ywg xav tau, peb soj ntsuam ua ke, li cas of:
Kev ncaj ncees ntawm cov xim sawv cev ncaj qha rau cuam tshuam rau lub ploj ntawm cov khoom, los ntawm lub teeb nrig ntawm cov khoom siv sab nrauv, cov xim uas siv rau hauv qib kawm yog qhov tseem ceeb, cov teeb meem tsis tshua zoo, qhov khoom yuav raug siv sai sai. Kev siv cov khoom siv uas siv rau hauv qib ua kom tsis muaj zog yuav tsum tsis pub tsawg tshaj rau, qhov zoo tshaj plaws ntawm xya, yim, cov khoom siv hauv tsev xaiv plaub plaub lossis tsib. Cov duab thaij duab ntawm tus cab kuj kuj muaj cov nyhuv rau cov xim hloov xim, thiab cov qauv ntawm cov duab tom qab tom qab UV irradiation yog faded. Qhov sib ntxiv ntawm ib lub teeb nris xws li lub ultraviolet absorber rau masterbatch pab txoj kev teeb pom kev ntawm qhov xim thiab xim yas khoom.
Lub thermal stability ntawm qhov kub-resistant pigment yog hais txog qhov ntsuas ntawm thermal poob, muaj suab nrov thiab lub suab ntawm cov pigment ntawm kev ntsuas kub. Cov dej paug nyob hauv cov pa yog cov hlau oxide, ntsev, zoo thermal stability, siab kub ua haujlwm. Thaum lub sij hawm sib xyaw organic ntawm cov pigment ntawm tej yam kub yuav tshwm sim hauv lub qauv molecular ntawm cov kev hloov thiab ib qho me me ntawm decomposition. Hauv particular, PP, PA, PET cov khoom, ua kub siab tshaj 280 ℃, xaiv tus neeg saib xyuas xim rau ntawm ib sab kom pom tseeb ntawm cov tshav kub tsis ua hauj lwm ntawm cov pigments, ntawm ib sab mus xav txog cov pigment tshav kub-resistant.
Antioxidant Qee cov organic pigments yog oxidized tom qab oxidative degradation ntawm macromolecules los yog lwm yam kev hloov tshwm sim. Cov txheej txheem no yog qhov kub oxidation nyob rau hauv tus txheej txheem thiab qhov thib ob yog oxidation ntawm cov oxidants muaj zog (xws li chromate hauv chrome) Cov pas dej, azo pigments thiab chrome daj sib xyaw siv, liab yuav maj mam zuj zus mus.
Acid-resistant coloring ntawm cov khoom yas thiab cov xim ntawm cov tshuaj ua hauj (acid thiab alkali tsis kam, redox kuj). Xws li cov molybdenum chromium red resistant acid, tab sis rhiab alkali, cadmium thiab daj tsis acid, ob lub pigments thiab phenolic resin rau ntawm ib co colorants los ntawm cov muaj zog txo cov nyhuv, tiag rau cov colorant kub tiv thaiv, weatherability thiab ploj.
