Cov tshuaj formula ntawm hlau oxide daj yog Fe2O3·H2O. Vim muaj cov dej siv lead ua, nws qhov kub-resistant kub yog: qis dua 140 / degree, tsis muaj xim, lub cev qhuav dej ntawm 270-300/ degree, thiab reddening, thiab xim maj mam tig liab thiab thaum kawg ua hlau liab. Nws yog dav siv hauv cov khoom yas thiab cov khoom yas. Los ntawm txheej txheej ntawm cov hlau daj, cov xim daj hlau tuaj yeem siv rau hauv qee qhov kev siv kub. Zinc Iron Yellow (CI Pigment Yellow 119) muaj cov tshuaj muaj pes tsawg leeg ntawm zinc ferrite nrog lub xim daj-daj.
Cov khoom tseem ceeb ntawm cov hlau oxide daj xim: Nws yog xim daj, yuav luag sib npaug ntawm chrome daj, muaj zog npog lub zog, ruaj khov rau lub teeb, thiab lub teeb nrawm tuaj yeem ncav cuag qib 8. Muaj huab cua tsis zoo. Hlau oxide daj tsuas yog haum rau cov xim ntawm cov roj hmab, EVA, thiab lwm yam vim nws cov cua sov tsis zoo. Tus nqi kuj qis thiab nws tsis muaj tshuaj lom thiab feem ntau yog siv hauv cov xim teeb thiab toning. Ua ke nrog phthalocyanine xiav thiab phthalocyanine ntsuab los tsim cov hlau sib xyaw phthalocyanine ntsuab rau kev tsim cov nyom dag thiab lwm yam khoom zoo sib xws.
Txhawm rau txhim kho nws cov cua sov, cov hlau oxide daj yog coated nrog cov sib xyaw ntawm silicon oxide thiab aluminium oxide, thiab sodium silicate tov yog ntxiv rau tag nrho cov hlau tawg tawg, thiab tom qab ntawd tus nqi pH raug kho kom nruab nrab nrog cov kua qaub, thiab silicic acid Sodium tsim silicic acid thiab yog hydrolyzed rau hauv silica thiab precipitates rau saum npoo ntawm hlau daj hais. Cov coated hlau oxide daj xim muaj cua sov ua haujlwm txog 260 degree, thiab muaj lub teeb pom kev zoo thiab huab cua tsis kam.
