Tshuaj Tshuaj Muaj Zog
Nws muaj ob hom barium chrome daj, ib qho yog Barium chromate [CACRO4], thiab lwm yam yog cov ntsev ntawm barium chromate thiab poov tshuaj chromate. Tshuaj mis mis yog Bak2 (Cro4) 2 lossis Bacroन 2Cro4. Chromium Barium oxide yog cream-daj hmoov, soluble hmoov, soluble hauv hydrochloric acid thiab nitric acid, nrog tinting tsis tshua muaj zog. Cov qauv hluav taws xob thoob ntiaj teb rau Barium Chromate yog ISO-2068-1972, uas yuav tsum tau hais tias cov ntsiab lus ntawm chomium trioxide tsis tsawg dua 36.5%. Poov Npas Potassium Chromate yog hmoov txiv qaub-daj. Vim yog cov poov tshuaj chromate, nws muaj qee qhov dej solubility. Nws cov kev txheeb ze yog 3.65, nws cov roj av refackstalst yog 1.6%, thiab nws cov ntim tshwj xeeb yog 300g / l.
Daim ntawv thov
Barium Chromate tsis tuaj yeem siv ua xim xim xim. Vim tias nws muaj Chromate, nws muaj cov txiaj ntsig zoo sib xws rau Zinc Chrome daj thaum siv hauv cov xim antirust. Poov Npas Potassium qhov tsis tau siv los ua cov xim xim, tab sis tsuas yog siv tau ua cov tshuaj tiv thaiv xeb, uas tuaj yeem hloov ib feem ntawm zinc daj. Los ntawm qhov kev pom ntawm kev txhim kho kev txhim kho, nws tsuas yog ib qho ntawm cov ntau yam ntawm cov txwv tsis pub muaj xeb pigments muaj nyob rau hauv kev lag luam txheej.
