Pigment Ubururu 28 CAS 1345-16-0

Umutungo wa Shimi:

Inzira ya molekulari	CoO · Al2O3
Ubucucike	4.26 [kuri 20 ℃]
Ibintu bifatika na shimi	Igice kinini cyubururu bwa cobalt ni CoO, Al2O3, cyangwa cobalt aluminate [CoAl2O4], ukurikije inyigisho ya formulaire ya chimique, Al2O3 ibirimo 57,63%, ibirimo CoO ni 42.36%, cyangwa ibirimo Co ni 33.31%, ariko ibigize nyabyo bya cobalt. pigment yubururu Al2O3 muri 65% ~ 70%, CoO hagati ya 30% ~ 35%, pigment yubururu bumwebumwe bwa cobalt irimo aside ya cobalt iri munsi yimwe cyangwa kimwe n'igice, kuko birashoboka kandi kuba harimo aside nkeya yibindi bintu, nka Ti, Li, Cr, Fe, Sn, Mg, Zn, nibindi. Nkuko isesengura ryubwoko bwibara ryitwa cobalt ryerekana ko CoO yayo ni 34%, Al2O3 ni 62%, ZnO ni 2% na P2O5 ni 2%. Birashoboka kandi ko ubururu bwa cobalt burimo alumina nkeya, icyatsi cya Cobalt (CoO · ZnO) na cobalt violet [Co2 (PO4) 2] Usibye ibice nyamukuru byo guhindura ibara ryubururu bwa cobalt. Ubu bwoko bwa pigment ni mubyiciro bya spinel, ni cube ifite spinel kristallisation. Ubucucike bugereranije ni 3.8 ~ 4.54, imbaraga zo kwihisha zifite intege nke cyane, 75 ~ 80g / m2 gusa, kwinjiza amavuta ni 31% ~ 37%, ingano yihariye ni 630 ~ 740g / L, ubwiza bwubururu bwa cobalt bukorwa muri kijyambere ibihe bitandukanye cyane nibicuruzwa byambere. Ibara ry'ubururu bwa Cobalt rifite ibara ryiza, irwanya ikirere cyiza, irwanya alkali, irwanya imiti itandukanye, irwanya ubushyuhe bugera ku 1200. Icyuka gikomeye kidakomeye ni munsi y’ibara ry’ibara ry’ubururu bwa phthalocyanine, kubera ko ribarwa ku bushyuhe bwinshi, nubwo nyuma yo gusya, ariko ibice biracyafite ubukana runaka.
Koresha	cobalt ubururu ni pigment idafite uburozi. Ibara ry'ubururu bwa Cobalt rikoreshwa cyane cyane mubushyuhe bwo hejuru bwokwirinda ubushyuhe, ceramika, emamel, amabara yikirahure, ibara ryinshi ryubushyuhe bwa plastike, kandi nkibintu byubuhanzi. Igiciro gihenze kuruta pigment ya organic organique, impamvu nyamukuru nigiciro kiri hejuru yibintu bya cobalt. Ubwoko bwamabara ya ceramic na enamel buratandukanye cyane nubwa plastiki hamwe nububiko.

Intangiriro

Ubwiza:

1. Ubururu bwa Cobalt nubururu bwijimye.

2. Ifite ubushyuhe bwiza kandi irwanya urumuri, kandi irashobora kugumana ituze ryibara ryayo mubushyuhe bwinshi.

3. Gushonga muri acide, ariko ntigashonga mumazi na alkali.

Koresha:

1. Ubururu bwa Cobalt bukoreshwa cyane mubutaka, ikirahure, ikirahure nizindi nganda.

2. Irashobora kugumya ibara ryubushyuhe bwinshi, kandi ikoreshwa muburyo bwo gushushanya no gushushanya.

3. Mu gukora ibirahure, ubururu bwa cobalt nabwo bukoreshwa nkibara, rishobora guha ikirahuri ibara ryubururu bwimbitse kandi ryongera ubwiza bwaryo.

Uburyo:

Hariho inzira nyinshi zo gukora cobalt ubururu. Uburyo bukoreshwa cyane ni ugukora imyunyu ya cobalt na aluminiyumu ku kigereranyo runaka kugirango ugire CoAl2O4. Ubururu bwa Cobalt burashobora kandi gutegurwa na synthesis ikomeye, icyiciro cya sol-gel nubundi buryo.

Amakuru yumutekano:

1. Guhumeka umukungugu nigisubizo cyikigo bigomba kwirindwa.

2. Mugihe uhuye nubururu bwa cobalt, ugomba kwambara uturindantoki two gukingira hamwe nibikoresho birinda amaso kugirango wirinde uruhu n amaso.

3.Nibikwiye kandi kuvugana ninkomoko yumuriro nubushyuhe bwo hejuru mugihe kirekire kugirango birinde kubora no kubyara ibintu byangiza.

4. Mugihe ukoresha no kubika, witondere uburyo bukoreshwa mubikorwa byumutekano.
