I-Pigment Blue 28 CAS 1345-16-0

Ipropati yeMichiza:

Ifomula yeemolekyuli	CoO·Al2O3
Ukuxinana	4.26[nge20℃]
IiPropati zoMzimba kunye nezeMichiza	Ukubunjwa okuphambili kwe-cobalt eluhlaza okwesibhakabhaka yi-CoO, i-Al2O3, okanye i-cobalt aluminate [CoAl2O4], ngokwe-chemical formula theory, umxholo we-Al2O3 ngu-57.63%, umxholo we-CoO ngu-42.36%, okanye umxholo we-Co yi-33.31%, kodwa ukubunjwa kwangempela kwe-cobalt i-pigment eluhlaza okwesibhakabhaka i-Al2O3 kwi-65% ~ 70%, i-CoO phakathi kwe-30% ~ 35%, enye i-cobalt blue pigment equlethe umxholo we-cobalt oxide iphantsi enye okanye enye enesiqingatha, kuba kunokwenzeka ukuba iqulethe ixabiso elincinci le-oxides yezinye izinto, ezifana ne-Ti, i-Li, i-Cr, i-Fe, i-Sn, i-Mg, i-Zn, njl. Njengoko uhlalutyo lweentlobo ze-cobalt blue pigment lubonisa ukuba i-CoO yayo yi-34%, i-Al2O3 yi-62%, i-ZnO yi-2% kunye ne-P2O5 yi-2%. Kwakhona kunokwenzeka ukuba i-cobalt eluhlaza okwesibhakabhaka iqulethe ixabiso elincinci le-alumina, i-Cobalt eluhlaza (CoO · ZnO) kunye ne-cobalt violet [Co2 (PO4)2] Ukongezelela ekubunjweni okuphambili ukutshintsha i-hue ye-cobalt blue pigment. Olu hlobo lwe-pigment lolweklasi ye-spinel, yityhubhu ene-spinel crystallization. Uxinaniso oluhambelanayo luyi-3.8 ~ 4.54, amandla okufihla abuthathaka kakhulu, kuphela i-75 ~ 80g / m2, ukufunxa kweoli yi-31% ~ 37%, umthamo othile ngu-630 ~ 740g / L, umgangatho we-cobalt blue eveliswa namhlanje. amaxesha ahluke kakhulu kulawo eemveliso zakuqala. I-Cobalt blue pigment inombala oqaqambileyo, ukuchasana kwemozulu okugqwesileyo, ukuxhathisa kwe-alkali, ukuchasana nezinyibiliki ezahlukeneyo, ukumelana nobushushu ukuya kuthi ga kwi-1200. I-poof eyona nto ibuthathaka ingaphantsi kwamandla ombala we-phthalocyanine blue pigment, kuba i-calcined kwiqondo lokushisa eliphezulu, nangona emva kokusila, kodwa amasuntswana asenobunzima obuthile.
Sebenzisa	i-cobalt blue yi-pigment engeyona inetyhefu. I-Cobalt blue pigment isetyenziselwa ikakhulu ukugquma ubushushu obuphezulu, iiseramikhi, i-enamel, umbala weGlasi, ubushushu obuphezulu obuxhathisa ubunjineli bemibala yeplastiki, kunye nebala lobugcisa. Ixabiso libiza kakhulu kune-pigment ye-inorganic jikelele, esona sizathu siphezulu lixabiso eliphezulu le-cobalt compounds. Iindidi ze-ceramic kunye nombala we-enamel zahluke kakhulu kwezo zeplastiki kunye neengubo.

Intshayelelo

Umgangatho:

1. I-Cobalt eluhlaza okwesibhakabhaka yikhompawundi eluhlaza okwesibhakabhaka.

2. Inokumelana nokushisa okulungileyo kunye nokumelana nokukhanya, kwaye inokugcina ukuzinza kombala wayo kumaqondo aphezulu.

3. Inyibilika kwi-asidi, kodwa ayinyibiliki emanzini nakwi-alkali.

Sebenzisa:

1. I-cobalt eluhlaza okwesibhakabhaka isetyenziswa ngokubanzi kwiiseramics, iglasi, iglasi kunye nezinye iindawo zoshishino.

2. Inokugcina ukuzinza kombala kumaqondo aphezulu, kwaye isoloko isetyenziselwa ukuhlobisa i-porcelain kunye nokudweba.

3. Kwimveliso yeglasi, i-cobalt blue iphinda isetyenziswe njengombala, onokunika iglasi umbala oluhlaza okwesibhakabhaka kunye nokwandisa ubuhle bayo.

Indlela:

Zininzi iindlela zokwenza i-cobalt eluhlaza okwesibhakabhaka. Eyona ndlela isetyenziswa ngokuqhelekileyo kukusabela i-cobalt kunye neetyuwa ze-aluminium kwinqanaba elithile le-molar ukwenza i-CoAl2O4. I-cobalt eluhlaza okwesibhakabhaka inokuthi ilungiswe nge-solid-phase synthesis, indlela ye-sol-gel kunye nezinye iindlela.

Ulwazi ngoKhuseleko:

1. Ukuphefumla uthuli kunye nesisombululo se-compound kufuneka kugwenywe.

2. Xa udibana ne-cobalt eluhlaza okwesibhakabhaka, kufuneka unxibe iiglavu ezikhuselayo kunye nezixhobo zokukhusela amehlo ukuze uthintele ukudibana kwesikhumba namehlo.

3. Kwakhona akufanelekanga ukuqhagamshelana nomthombo womlilo kunye nokushisa okuphezulu ixesha elide ukukhusela ukubola kunye nokuvelisa izinto ezinobungozi.

4. Xa usebenzisa kwaye ugcina, nikela ingqalelo kwiinkqubo ezifanelekileyo zokusebenza zokhuseleko.
