uhlobo
Uhlobo oluyinhloko lwamadayi e-sulphur yi-sulphur black (CI sulphur black 1). Ilungiswa ngokufaka i-hydrolyzing 2, 4-dinitrochlorobenzene kanye nesisombululo se-sodium hydroxide kusisombululo se-sodium dinitrophenol lapho icishe ibile, bese ifudunyezwa futhi ibiliswe ngesisombululo se-sodium polysulfide ngesilinganiso esithile sama-molecule, kanye nokunciphisa kanye nokusabela kwe-sulphurzing ngaphansi kwengcindezi noma kungekho ngcindezi. Ngemva kokuthi ukusabela kwe-sulphurization sekuqediwe, komiswa ngqo nge-roller dryer ukuze kutholakale udayi wokuqala. Bese kuhlanganiswa namadayi okuhweba. Ngesikhathi se-vulcanization, isilinganiso sama-molecule se-sodium phenol kanye ne-sodium polysulfide, i-x(ie, i-sulphur index) ku-sodium polysulfide Na2Sx kanye nokushisa kokusabela kuhlukile, ukuze ukukhanya kombala womkhiqizo we-sulphur black kube nomehluko wokukhanya okuluhlaza, ukukhanya okubomvu okuluhlaza kanye nokukhanya okubomvu. Inkinga enkulu yedayi emnyama ye-sulphur yinto yendwangu ephukile. Lokhu kungenxa yokuthi i-molecule emnyama ye-sulfide iqukethe i-sulphur esebenzayo ngesimo samaketanga e-polysulfide. Lokhu kwakheka kwe-sulphur akuzinzile, futhi uma idayi ishiswa noma ifakwa emoyeni oshisayo nonomswakama, kulula ukuyixuba ibe yi-sulfuric acid, okuholela ekuqhekekeni kwendwangu kakotini. Eminyakeni yamuva nje, ngokuthuthukisa inqubo yokukhiqiza i-sulphur black, i-sulphur black evamile ipholiswa cishe ku-100℃ ngemva kokwenziwa, bese kwengezwa i-formaldehyde ne-monochloroacetic acid ukuze kuzinziswe i-sulphur engazinzile kudayi, bese kwenziwa i-anti-brittle sulphur black dyeing.
Sebenzisa
Amadayi esibabule asetshenziselwa ukunciphisa abe yi-leucosome encibilika emanzini nge-sodium sulfide noma i-insure powder, bese eshintshwa abe yinto enombala engancibiliki yokuqala ngemva kokumuncwa yidayi nge-oxidation noma eminye imiphumela, ukuze idayi inamathele kudayi.
Faka isicelo
Amadayi esibabule asetshenziswa kakhulu ekudayini imicu ye-cellulose, asetshenziswa kakhulu ezintanjeni, ezimweni nakwezinye izindwangu zezimboni kanye nezindwangu ezisindayo. Izinhlobo ezisetshenziswa kakhulu yi-sulphur Yuan, i-sulphur blue,
Isixazululo sokunciphisa
(1) Izakhiwo zama-ejenti okunciphisa
1. Izakhiwo ze-Na2S
(1) Eyaziwa nangokuthi i-alkali sulfide, igama elivamile elithi i-alkali enuka kabi, ukwakheka okusebenzayo kwe-alkali sulfide yezimboni ngokuvamile kungama-50%, futhi ukubukeka kwayo kuyisithako esiphuzi-nsundu. Kuyisithako esinciphisayo, kodwa futhi kuyi-alkali agent eqinile, izakhiwo ezizinzile. Amandla okunciphisa e-sodium sulfide aphansi kune-powder yomshuwalense, i-alkalinity iphansi kune-caustic soda futhi iphakeme kune-soda ash, futhi inokugqwala okunamandla esikhumbeni.
(2) Ukushiswa kwe-sodium sulfide ku-NaHS, i-NaHS ekunciphiseni udayi, kungabonakala ukuthi amandla okunciphisa i-sodium sulfide ahlobene nokushiswa kwayo.
(3) I-Sodium sulfide ikhiqiza igesi ye-H2S uma ihlangana ne-asidi, ngakho-ke kufanele kuqashelwe ukuthi ingahlanganiswa ne-asidi.
(4) Ukuvezwa kwe-sodium sulfide emoyeni kuzomunca amanzi, i-C02, i-02, njll., ukuze ukwakheka okusebenzayo kunciphe futhi kuhluleke kancane kancane. Ngakho-ke, kufanele kuvalwe lapho kugcinwa, futhi ukwakheka kwayo kufanele kuhlaziywe uma kungasasetshenziswa isikhathi eside.
(5) Isixazululo se-sodium sulfide akufanele sibe side, ngaphandle kwalokho sizoncishiswa umoya futhi sinciphise ukusebenza kwaso.
sebenzisa
Isetshenziswa kakhulu ukotini, ukudaya i-hemp fiber
Inkampani yethu ikhiqiza kakhuluI-Sulphur Black Blue,I-Sulphur Blue Brn engu-150%,I-Sulphur Red 14,Amadayi Abomvu E-Sulphurkanye nezinye izinhlobo eziningi ze-sulphur dyes, ezithengiswa ekhaya nakwamanye amazwe, njengeBangladesh, Pakistan, Turkey, India, Vietnam, Italy, njll. Iqashelwe futhi yanconywa iningi lamakhasimende, ngenxa yokuqapha kwethu okuhle kanye nezinzuzo zentengo ephansi. Sibonga futhi amakhasimende ethu ngokusekela nokuqaphela inkampani yethu.
