Pigment Blue 28 CAS 1345-16-0

Chemical Property:

Molecular Formula	CoO·Al2O3
Qhov ntom	4.26 [ntawm 20 ℃]
Physical thiab Chemical Properties	Lub ntsiab muaj pes tsawg leeg ntawm cobalt xiav yog CoO, Al2O3, los yog cobalt aluminate [CoAl2O4], raws li cov tshuaj formula txoj kev xav, Al2O3 ntsiab lus yog 57.63%, CoO ntsiab lus yog 42.36%, los yog Co cov ntsiab lus yog 33.31%, tab sis qhov tseeb muaj pes tsawg leeg ntawm cobalt Cov xim xiav Al2O3 hauv 65% ~ 70%, CoO ntawm 30% ~ 35%, qee cov cobalt Cov xim xiav uas muaj cov ntsiab lus cobalt oxide qis dua ib lossis ib nrab, vim tias nws tseem tuaj yeem muaj cov oxides me me ntawm lwm cov ntsiab lus, xws li Ti, Li, Cr, Fe, Sn, Mg, Zn, thiab lwm yam. Kev tsom xam ntawm cov xim xiav cobalt pom tias nws cov CoO yog 34%, Al2O3 yog 62%, ZnO yog 2% thiab P2O5 yog 2%. Nws kuj tseem ua tau rau cobalt xiav kom muaj me me ntawm alumina, Cobalt ntsuab (CoO · ZnO) thiab cobalt violet [Co2 (PO4) 2] Ntxiv rau cov ntsiab lus tseem ceeb los hloov cov xim ntawm cobalt xiav xim. Cov xim no yog nyob rau hauv chav kawm spinel, yog lub voos xwmfab nrog spinel crystallization. Cov txheeb ze ntom ntom yog 3.8 ~ 4.54, lub zog zais yog qhov tsis muaj zog, tsuas yog 75 ~ 80g / m2, cov roj nqus yog 31% ~ 37%, qhov tshwj xeeb ntim yog 630 ~ 740g / L, qhov zoo ntawm cobalt xiav ua nyob rau hauv niaj hnub lub sij hawm yog qhov tseem ceeb sib txawv ntawm cov khoom thaum ntxov. Cobalt xiav xim muaj xim ci, huab cua zoo heev, alkali tsis kam, tsis kam mus rau ntau cov kuab tshuaj, tshav kub tsis kam mus txog 1200. Lub ntsiab tsis muaj zog poof yog tsawg dua xim lub zog ntawm phthalocyanine xiav xim, vim nws yog calcined ntawm qhov kub thiab txias, tab sis tom qab sib tsoo, tab sis cov khoom tseem muaj qee qhov hardness.
Siv	cobalt xiav yog cov xim tsis muaj tshuaj lom. Cobalt xiav pigment yog tsuas yog siv rau kub resistant coatings, ceramics, enamel, iav xim, kub resistant engineering yas xim, thiab raws li ib tug kos duab xim. Tus nqi yog kim dua li cov xim inorganic dav dav, qhov laj thawj tseem ceeb yog tus nqi siab dua ntawm cobalt compounds. Ntau hom xim ceramic thiab enamel yog qhov sib txawv ntawm cov yas thiab txheej txheej.

Cov ntaub ntawv kev nyab xeeb:

1. Kev nqus cov plua plav thiab kev daws ntawm cov tshuaj yuav tsum zam.

2. Thaum nkag mus rau hauv kev sib cuag nrog cobalt xiav, koj yuav tsum hnav hnab looj tes tiv thaiv thiab tiv thaiv qhov muag kom tsis txhob muaj tawv nqaij thiab qhov muag.

3. Nws kuj tsis tsim nyog hu rau qhov hluav taws kub thiab kub siab rau lub sijhawm ntev los tiv thaiv nws los ntawm decomposing thiab tsim cov khoom tsis zoo.

4. Thaum siv thiab khaws cia, ua tib zoo saib xyuas cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm.
