Iimpahla zedenim ezidaywe ngeSulfur Black BR zithandwa kakhulu.Izixhobo zokudaya esizisebenzisayo zisebenzisa indlela yokuprinta ngokuqhubekayo kunye nokudaya kwe-warp shaft, kwaye inkqubo yokuvelisa ikhulile.I-Sulfur Black BR ayinyibiliki emanzini, kodwa, inokunyibilika kwisisombululo se-sodium sulfide ngokubuyela kumbala ofihliweyo.Lo mzimba wombala ufihliweyo unokudaywa kwimicu ye-cellulose ukugqiba inkqubo yokudaya.Iimpawu zedayi zesulfure zifana nezo zedayi ezithe ngqo kunye nedayi ye-vat.I-reductant ye-Sulfur Black BR, i-sodium sulfide, ine-reducibility ebuthakathaka, ngoko akulula ukuba isulfure emnyama iyancipha.Ngelo xesha, i-Sulfur Black BR izinzile kwiqondo lokushisa eliphezulu.Xa idayi ye-Sulfur Black BR iyancitshiswa kwaye inyibilika nge-sodium sulfide, ivelisa i-thiophenol, eguqulwa ibe yi-sodium sulfide kwaye inyibilike.
Isisombululo sedayi esakhiwe ngeedayi zesulfure ezincitshiswe yi-sodium sulfide azinzile ngokwaneleyo.Idayi ye-Sulfur Black BR kufuneka ihlanjwe ngokupheleleyo ukususa i-sodium sulfide eseleyo kwilaphu kwaye inokuthi ifakwe ngokupheleleyo emoyeni.Ubungakanani be-sodium sulfide esetyenziselwa ukubuyisela kunye nokuchithwa kweSulfur Black BR ayikwazi ukubalwa ngokuchanekileyo.
Emva kokudaya ifayibha ngedayi yeSulfur Black BR, kufuneka ifakwe i-oxidized ukuze ibe yidayi enganyibilikiyo kwaye igxininiswe kwifayibha.isulfure emnyama inokuthi ifakwe i-oxidized ukuba nje ihlanjiwe kwaye ingena umoya.Xa idayi ngeedayi ngesantya oxidation ngokukhawuleza leuco compound, ukuba idayi evezwe emoyeni okanye sodium sulfide ayanelanga, iya kuba oxidized kwangaphambi kwexesha ukuvelisa ibala.Iidayi ngaphandle kwesulfure emnyama zinokuphathwa nge-ejenti yokulungisa ukuphucula ukukhawuleza kombala.I-Copper sulfate inokwenza i-fiber brittle ye-Sulfur Black BR, ngoko ke i-sulfate yobhedu ayinakusetyenziselwa ukulungiswa.
