Tam sim no, cov pigments uas tsim nyog rau cov hmoov txheej tuaj yeem muab faib ua plaub pawg: cov xim muaj xim, xim xim hlau, xim xim muaj nuj nqi, thiab cov xim pleev xim ntxiv raws li lawv lub zog thiab siv.
Ntxiv nrog rau muab cov xim ntau rau cov hmoov txheej, pigments kuj tseem tuaj yeem txhim kho cov txheeb ze cov khoom ntawm cov hmoov txheej thiab txo tus nqi. Hauv kev siv, cov tseev kom muaj ntawm hmoov txheej rau cov xim muaj: cov pigments tsis hnov mob thaum lub sijhawm npaj, khaws cia, tsheb thauj mus los thiab siv cov hmoov txheej; cov pigments yuav tsum ruaj khov thiab tsis cuam tshuam los ntawm huab cua, av noo thiab ib puag ncig; nyob rau hauv cov nqe lus ntawm cov xim, Cov xim muaj dispersibility, tinting zog, zais zog thiab kub kuj yuav tsum tau. Nquag, qhov zoo tshaj plaws dispersion particle loj yog 0.2 ～ 0.7μm, thiab qhov kub tsis kam yuav tsum siab tshaj 180 ℃, vim tias cov hmoov txheej dav dav yog ci ntawm 180 at 200 ℃; cov xim yuav tsum muaj lub teeb zoo heev thiab huab cua tsis kam, tshwj xeeb tshaj yog nyob rau hauv cov huab cua tiv thaiv cov hmoov av, lub teeb tiv thaiv yuav tsum yog qib 7-8, thiab huab cua tiv thaiv yuav tsum ncav cuag 5 lossis ntau dua; thaum kawg, cov roj nqus ntawm cov pigments yuav tsum muaj mob pesnrab, Impermeability zoo dua; Ntxiv rau, nws yog qhov zoo tshaj plaws kom tsis txhob siv cov xim muaj kuab lom, xws li cov hlau lead, cadmium, chromium toxic hlau xim. Cov yam ntxwv ntawm cov hlau oxide pigments cia li ua tau raws li cov yam ntxwv tau piav saum toj no, thiab lawv muaj peev xwm zoo rau kev siv rau hauv cov hmoov txheej. Ntsib nrog cov teeb meem ntawm cov xim tsis zoo xim vividness ntawm hlau oxide pigments, organic pigments thiab hlau oxide pigments feem ntau yog sib xyaw xim kom ua tiav cov xim hue.
