Pigment Blue 28 CAS 1345-16-0

Chemical Property:

Molecular Formula	CoO·Al2O3
Kuchulukana	4.26 [pa 20 ℃]
Zakuthupi ndi Zamankhwala	Chopangidwa chachikulu cha cobalt buluu ndi CoO, Al2O3, kapena cobalt aluminate [CoAl2O4], malinga ndi chiphunzitso chamankhwala, Al2O3 zili 57.63%, zomwe zili mu CoO ndi 42.36%, kapena Co zili 33.31%, koma mawonekedwe enieni a cobalt. buluu pigment Al2O3 mu 65% ~ 70%, CoO pakati 30% ~ 35%, cobalt blue pigment yomwe ili ndi cobalt oxide imakhala yotsika ndi imodzi kapena theka, chifukwa ndizothekanso kukhala ndi ma oxides azinthu zina, monga Ti, Li, Cr, Fe, Sn, Mg, Zn, etc. Monga momwe kuwunika kwa mtundu wa cobalt blue pigment kukuwonetsa kuti CoO yake ndi 34%, Al2O3 ndi 62%, ZnO ndi 2% ndi P2O5 ndi 2%. N'zothekanso kuti cobalt buluu ikhale ndi alumina pang'ono, Cobalt wobiriwira (CoO · ZnO) ndi cobalt violet [Co2 (PO4)2] Kuwonjezera pa kupanga kwakukulu kusintha mtundu wa cobalt blue pigment. Mtundu uwu wa pigment ndi wa gulu la spinel, ndi cube yokhala ndi spinel crystallization. Kachulukidwe wachibale ndi 3.8 ~ 4.54, mphamvu yobisala ndiyofooka kwambiri, 75 ~ 80g/m2 yokha, kuyamwa kwamafuta ndi 31% ~ 37%, voliyumu yeniyeni ndi 630 ~ 740g/L, mtundu wa cobalt buluu wopangidwa masiku ano. nthawi zimasiyana kwenikweni ndi zomwe zidayamba kale. Cobalt blue pigment ili ndi mtundu wowala, kukana kwa nyengo yabwino, kukana kwa alkali, kukana zosungunulira zosiyanasiyana, kukana kutentha mpaka 1200. Phokoso lalikulu lofooka ndilochepa kuposa mphamvu ya mtundu wa phthalocyanine blue pigment, chifukwa ndi calcined pa kutentha kwakukulu, ngakhale pambuyo akupera, koma particles akadali ndi kuuma kwina.
Gwiritsani ntchito	cobalt blue ndi pigment yopanda poizoni. Cobalt blue pigment imagwiritsidwa ntchito kwambiri popangira zokutira kutentha kwambiri, zoumba, enamel, utoto wagalasi, utoto wa pulasitiki wosagwira kutentha kwambiri, komanso ngati utoto waluso. Mtengo wake ndi wokwera mtengo kwambiri kuposa wamba wamba, chifukwa chachikulu ndikukwera mtengo wamafuta a cobalt. Mitundu yamitundu ya ceramic ndi enamel ndi yosiyana kwambiri ndi mapulasitiki ndi zokutira.

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Mawu Oyamba

Ubwino:

1. Cobalt buluu ndi buluu wakuda.

2. Imakhala ndi kutentha kwabwino komanso kukana kuwala, ndipo imatha kusunga kukhazikika kwa mtundu wake pa kutentha kwakukulu.

3. Kusungunuka mu asidi, koma osasungunuka m'madzi ndi zamchere.

Gwiritsani ntchito:

1. Cobalt buluu amagwiritsidwa ntchito kwambiri muzoumba, magalasi, magalasi ndi mafakitale ena.

2. Ikhoza kusunga kukhazikika kwa mtundu pa kutentha kwakukulu, ndipo nthawi zambiri imagwiritsidwa ntchito pokongoletsa porcelain ndi kujambula.

3. Popanga magalasi, cobalt buluu amagwiritsidwanso ntchito ngati mtundu, womwe ukhoza kupatsa galasi mtundu wa buluu wakuya ndikuwonjezera kukongola kwake.

Njira:

Pali njira zambiri zopangira cobalt buluu. Njira yomwe imagwiritsidwa ntchito kwambiri ndikuyankhira mchere wa cobalt ndi aluminiyamu pamlingo wina wa molar kupanga CoAl2O4. Cobalt buluu imatha kukonzedwanso ndi kaphatikizidwe kolimba, njira ya sol-gel ndi njira zina.

Zambiri Zachitetezo:

1. Kupuma kwa fumbi ndi yankho la pawiri kuyenera kupewedwa.

2. Mukakumana ndi buluu wa cobalt, muyenera kuvala magolovesi oteteza ndi zida zoteteza maso kuti musayang'ane khungu ndi maso.

3. Sikoyeneranso kukhudzana ndi gwero la moto ndi kutentha kwakukulu kwa nthawi yaitali kuti zisawonongeke ndi kupanga zinthu zovulaza.

4. Mukamagwiritsa ntchito ndikusunga, samalani ndi njira zoyendetsera chitetezo.
