Muaj Hom: Phthalate esters; Cov roj zaub (natural oil), roj ntxhia.
Hom Synthetic Resins: Cov khoom tseem ceeb ntawm cov khoom siv hluavtaws siv yog rosin thiab nws cov derivatives; roj av resins; thiab polyester resins.
Muab kuv lub teb chaws thaj chaw loj heev, xaiv cov resins tsim nyog rau thaj tsam sib txawv yog qhov tseem ceeb. Hauv kev tsim khoom tiag tiag, siv ntau tshaj ib hom resin; ob lossis ntau dua resins tuaj yeem siv los kho ntau yam khoom ntawm cov xim. Thaum siv ntau tshaj ib hom resin, resins nrog cov khoom sib xws yuav tsum raug xaiv.
Coloring Pigments: Cov xim tseem ceeb ntawm txoj kev kos xim yog xim dawb thiab daj, ua haujlwm xim thiab npog. Cov xim dawb yog ib qho tseem ceeb ntawm kev txhawb nqa 45℃diffusion reflectance (whiteness) ntawm cov xim zaj duab xis.
Qhov yuav tsum tau muaj rau Pigments: Kub kub kuj; muaj zog zais zog; ci xim.
Muaj Hom:
Dawb Pigments: Titanium dioxide, zinc oxide, thiab lwm yam.
Yellow Pigments: Kub-resistant chrome daj, organic daj pigments, hlau oxide, thiab lwm yam.
Thaum cov pigments tau ntxiv los ua cov tshuaj pleev xim rau cov txheej txheem, lawv cuam tshuam rau cov khoom siv dag zog, kev ua haujlwm tsis zoo, thiab xim ntawm cov zaj duab xis txheej. Qhov loj ntawm cov xim txiav txim siab qhov fluidity thiab daws cov khoom ntawm cov txheej, thiab tseem cuam tshuam rau qhov chaw tiav.
