Izinhlobonhlobo eziyinhloko zodayi besulfure yi-sulphur black (CI sulfur black 1).Ilungiswa nge-hydrolyzing 2, 4-dinitrochlorobenzene kanye nesisombululo se-sodium hydroxide kusixazululo se-sodium dinitrophenol lapho sibilisa, bese sishisisa futhi sibiliswe ngesisombululo se-sodium polysulfide ngesilinganiso esithile samangqamuzana, kanye nokunciphisa kanye nokusabela kwe-sulfurizing ngaphansi kwengcindezi noma ngaphandle kwengcindezi.Ngemva kokuqedwa kwe-sulfurization reaction, yomiswa ngokuqondile nge-roller dryer ukuze kutholwe udayi wokuqala.Ibe isihlanganiswa ibe odayi bezentengiselwano.Ngesikhathi se-vulcanization, isilinganiso samangqamuzana e-sodium phenol ne-sodium polysulfide, i-x(okungukuthi, inkomba yesibabule) ku-sodium polysulfide Na2Sx kanye nezinga lokushisa lokusabela lihlukile, ukuze ukukhanya kombala womkhiqizo omnyama wesulfure kube nomehluko wokukhanya okuluhlaza, okuluhlaza okotshani. ukukhanya okubomvu nokukhanya okubomvu.Ukungalungi okukhulu kodayi omnyama wesulfure yisimo sendwangu e-brittle.Lokhu kungenxa yokuthi i-molecule emnyama ye-sulfide iqukethe isulfure esebenzayo esesimweni samaketanga e-polysulfide.Lokhu kwakheka kwesibabule akuzinzile, futhi lapho udayi ushisisiwe noma ubekwe emoyeni oshisayo noswakeme, kulula uku-oxidize ku-sulfuric acid, okuholela ekushwabaneni kwendwangu kakotini.Eminyakeni yamuva nje, ngokwenza ngcono inqubo yokukhiqizwa kwesibabule esimnyama, isibabule esimnyama esijwayelekile sipholiswa sifinyelele ku-100 ℃ ngemva kokwenziwa, futhi i-formaldehyde ne-monochloroacetic acid yengezwa ukuze kunzinzise isibabule esingazinzile kudayi, kanye ne-anti-brittle sulfur black. ukudaya kwenziwa.
Sebenzisa
Odayi besulfure basetshenziselwa ukuncishiswa babe yi-leucosome encibilika emanzini nge-sodium sulfide noma impushana yomshwalense, bese beshintshwa babuyele endabeni yombala engancibiliki ngemva kokumuncwa udayi ngokusebenzisa i-oxidation noma eminye imiphumela, ukuze udayi ugxile kudayi. .
Faka isicelo
odayi besulfure basetshenziswa kakhulu ekudayeni imicu ye-cellulose, ikakhulukazi esetshenziswa emiculweni, emimoyeni nakwezinye izindwangu zezimboni nezindwangu ezinzima.Izinhlobo ezisetshenziswa kakhulu yi-Sulfur Yuan, sulfur blue,
Isixazululo esinciphisayo
(1) Izakhiwo zama-ejenti anciphisayo
1. Izakhiwo ze-Na2S
(1) Eyaziwa nangokuthi i-alkali sulfide, igama elivamile i-alkali enukayo, ukwakheka okusebenzayo kwe-alkali sulfide yezimboni ngokuvamile cishe ku-50%, futhi ukubonakala kuqinile ngokuphuzi ngokunsundu.I-ejenti yokunciphisa, kodwa futhi i-alkali eqinile, izakhiwo ezinzile.Umthamo wokunciphisa we-sodium sulfide uphansi kunalowo wempushana yomshwalense, i-alkalinity iphansi kune-caustic soda futhi inkulu kunomlotha wesoda, futhi inokugqwala okuqinile esikhumbeni.
(2) I-Sodium sulfide hydrolysis ku-NaHS, i-NaHS ekunciphiseni udayi, kungabonakala ukuthi umthamo wokunciphisa i-sodium sulfide uhlobene ne-hydrolysis yayo.
(3) I-sodium sulfide ikhiqiza igesi ye-H2S lapho ihlangana ne-asidi, ngakho kufanele kuqashelwe ukuze ingahlanganiswa ne-asidi.
(4) Ukuchayeka kwe-sodium sulfide emoyeni kuzomunca amanzi, i-C02, i-02, njll., ukuze ukwakheka okuphumelelayo kuncipha futhi kancane kancane kuhluleke.Ngakho-ke, kufanele ivalwe uma igcinwe, futhi ukubunjwa kwayo kufanele kuhlaziywe uma ingasetshenziswa kabusha isikhathi eside.
(5) Isixazululo se-sodium sulfide akufanele sibe side, ngaphandle kwalokho sizobe senziwe nge-oxidized emoyeni futhi sinciphise ukusebenza kwayo.
sebenzisa
Isetshenziselwa kakhulu ukotini, ukudaya i-fiber ye-hemp
Inkampani yethu ikhiqiza kakhuluIsibabule Esimnyama Esiluhlaza,I-Sulfur Blue Brn 150%,Isibabule Esibomvu 14,I-Sulfur Red Dyeskanye nabanye odayi abaningi besulfure, abathengiswa ekhaya naphesheya, njengeBangladesh, Pakistan, Turkey, India, Vietnam, Italy, njll. Kuye kwaqashelwa futhi kwanconywa iningi lamakhasimende, ngenxa yokuqondisa kwethu okuhle nokuphansi. izinzuzo zentengo.Siphinde sibonge amakhasimende ethu ngokuseseka nokuqaphela inkampani yethu.
