Ingabe Uyazi NgeSulfur Black?

i-sulphur black, eyaziwa nangokuthi i-ethyl sulfur pyrimidine, idayi yokwenziwa yemvelo esetshenziswa kakhulu ekudayeni, ezimbonini ze-pigment neziyinki. Embonini yezindwangu, udayi omnyama wesulfure uwudayi oyinhloko wokudaya imicu ye-cellulose, elungele ikakhulukazi imikhiqizo emnyama yezindwangu zikakotini, phakathi kwazo.

I-Liquid Sulfur BlackfuthiSulfur Blue 7yizona ezivame kakhulu. Inqubo yokudaya idayi yesulfure iwukuthi: okokuqala, idayi yesulfure iyancishiswa futhi ihlakazwe ibe yisisombululo sedayi, futhi izintambo zokudaya ezakhiwe zikhangiswa yizintambo ze-cellulose, bese ziphathwa nge-oxidation yomoya ukuze wenze imicu ye-cellulose ibonise umbala odingekayo.

Ukudaya okumnyama kwesibabule kudinga i-sodium sulfide njenge-ejenti yokunciphisa ukuncibilikisa udayi. Odayi be-sulfide ngokwabo abancibiliki emanzini, futhi lapho kusetshenziswa ama-alkaline reduction agents, odayi bangancishiswa babe yi-leucochromes futhi bancibilike emanzini, futhi usawoti we-leucochromic sodium owenziwe ungakhangiswa ngemicu. Enkambweni yangempela yokusebenza, inqubo yokunciphisa kanye nokuqedwa kwamadayi e-sulfide idinga ukwenziwa ngokugcwele, futhi izinga lokwengeza kufanele libe kancane futhi lifane. Ngemva kokwengeza udayi, ubilise futhi udaye imizuzu engu-10, bese kancane kancane ufaka usawoti ngokulinganayo ukuze ukhuthaze ukudaya. Qinisekisa ukuthi uhlanza kahle ngemva kokudaya ukuze uvimbele udayi osele ukuthi ungaphazamisi umphumela wokudaya. Ngaphezu kwalokho, ngemva kokudaya, ungapholi ngokuzumayo ukuze uvimbele “izidladla zezinyoni”. Ngesikhathi esifanayo, ukwelashwa kwe-anti-brittleness kudinga ukusetshenziswa kwezithambisa ngesikhathi sokudaya.

Ngaphezu kwalokho, i-sulphur black nayo ingasetshenziselwa ukukhiqiza ama-pigments, ngenxa yokumelana nokukhanya okuhle kanye nokumelana nesimo sezulu, ngakho-ke isetshenziswa kabanzi embonini ye-pigment. Ekwenziweni kwe-inki, ukusetshenziswa kwesibabule esimnyama nakho kubanzi kakhulu, njengoyinki noyinki wokuphrinta, umbala wawo ujulile, unganikeza umphumela omuhle wokuphrinta, futhi unokumelana namanzi, ukumelana nokugqoka kanye nokumelana namakhemikhali.
