Zvenyama uye Chemical Properties	Iyo yakanyanya kuumbwa yecobalt bhuruu ndeye CoO, Al2O3, kana cobalt aluminate [CoAl2O4], maererano nemakemikari formula theory, Al2O3 yemukati ndeye 57.63%, CoO yemukati ndeye 42.36%, kana Co yemukati ndeye 33.31%, asi iyo chaiyo kuumbwa kwecobalt. bhuruu pigment Al2O3 mu65% ~ 70%, CoO pakati pe30% ~ 35%, imwe cobalt yebhuruu pigment ine cobalt oxide yemukati yakadzikira neimwe kana imwe nehafu, nekuti zvinogoneka kuve neadiki maokisi ezvimwe zvinhu, seTi, Li, Cr, Fe, Sn, Mg, Zn, nezvimwe. Sezvo kuongororwa kwerudzi rwecobalt blue pigment kunoratidza kuti CoO yayo i34%, Al2O3 i62%,ZnO 2% uye P2O5 2%. Izvo zvakare zvinogoneka kuti cobalt bhuruu ive nehushoma hwealumina, Cobalt yakasvibirira (CoO · ZnO) uye cobalt violet [Co2 (PO4)2] Mukuwedzera kune yakakosha kuumbwa kwekuchinja hue ye cobalt blue pigment. Rudzi urwu rwe pigment ndeyespinel class, cube ine spinel crystallization. Kuwanda kwehukama ndeye 3.8 ~ 4.54, simba rekuhwanda harina kusimba, chete 75 ~ 80g / m2, kunyura kwemafuta kuri 31% ~ 37%, iyo chaiyo vhoriyamu i630 ~ 740g/L, mhando yecobalt yebhuruu inogadzirwa mazuva ano. nguva dzakatosiyana nedzezvigadzirwa zvekutanga. Cobalt blue pigment ine ruvara rwakajeka, yakanakisa kupikisa kwemamiriro ekunze, alkali kushorwa, kupikisa kune zvakasiyana-siyana zvinonyungudutsa, kupisa kupisa kusvika ku 1200. Iyo huru isina simba poof ishoma pane simba reruvara rwe phthalocyanine blue pigment, nekuti inoverengerwa pakupisa kwakanyanya, kunyangwe mushure mekugaya, asi zvimedu zvichine imwe kuoma.
Shandisa	cobalt bhuruu isiri-chepfu pigment. Cobalt bhuruu pigment inonyanya kushandiswa kune yakakwira tembiricha inodzivirira machira, ceramics, enamel, Girazi coloring, yakakwirira tembiricha inodzivirira engineering epurasitiki coloring, uye senge pigment. Mutengo wacho unodhura kupfuura general inorganic pigment, chikonzero chikuru mutengo wepamusoro wecobalt makomputa. Iwo akasiyana eceramic uye enamel coloring akasiyana chaizvo neaya emapurasitiki uye machira.

2. Iine hutano hwakanaka hwekupisa uye chiedza chekudzivirira, uye inogona kuchengetedza kugadzikana kwemuvara wayo pakupisa kwepamusoro.

3. Soluble muasidhi, asi isinganyunguriki mumvura uye alkali.

Shandisa:

1. Cobalt yebhuruu inoshandiswa zvakanyanya mumakeramiki, girazi, girazi uye mamwe maindasitiri minda.

2. Inogona kuchengetedza kugadzikana kwemavara pakupisa kwepamusoro, uye inowanzoshandiswa pakushongedza porcelain nekupenda.

3. Mukugadzira girazi, cobalt yebhuruu inoshandiswawo semuvara, iyo inogona kupa girazi ruvara rwebhuruu rwakadzika uye kuwedzera aesthetics.

Nzira:

Kune nzira dzakawanda dzekuita cobalt bhuruu. Nzira inonyanya kushandiswa ndeyekuita cobalt uye aluminium munyu pane imwe molar ratio kuumba CoAl2O4. Cobalt yebhuruu inogonawo kugadzirirwa ne-soli-phase synthesis, sol-gel nzira uye dzimwe nzira.

Zvekuchengetedza

1. Inhalation yeguruva uye mhinduro yemusanganiswa inofanira kudziviswa.

2. Paunosangana necobalt blue, unofanira kupfeka magirovhosi ekudzivirira uye midziyo yekudzivirira maziso kudzivirira ganda uye maziso.

3. Izvo hazvina kukodzerawo kubata chitubu chemoto uye kupisa kwepamusoro kwenguva yakareba kuti zvidzivirire kubva pakuora uye kubudisa zvinhu zvinokuvadza.

4. Paunenge uchishandisa nekuchengetedza, teerera kune akakodzera maitiro ekuchengetedza ekuchengetedza.
