Amadayi esibabule ayidayi ancibilikiswa ku-alkali sulphur. Asetshenziswa kakhulu ekudayiseni imicu kakotini futhi angasetshenziswa nasezindwangu ezixutshwe ukotini/amavithamini. Izindleko ziphansi, udayi ngokuvamile uyakwazi ukuwasha futhi uyashesha, kodwa umbala awukhanyi ngokwanele. Izinhlobo ezivame ukusetshenziswa yileziI-Sulphur Blue 7,I-Sulphur Red 14 I-Sulphur Black Bluishandnjalo njalo. Amadayi esibabule ancibilikayo aseyatholakala manje. Idayi eyakhiwe ukusabela kwe-vulcanization kwama-amine, ama-phenol, noma ama-nitro compounds ama-hydrocarbon aromatic ane-sulfur noma i-sodium polysulphur,
okungavamile
Amadayi esibabule awancibiliki emanzini, kanti i-sodium sulphur noma ezinye izinto zokunciphisa zisetshenziselwa ukunciphisa amadayi abe ama-leucochrome ancibilikayo. Inobuhlobo nefayibha futhi ingcolisa ifayibha, bese ibuyisela isimo sayo sokungancibiliki ngokufaka i-oxidation kanye nokuqina kufayibha. Ngakho-ke idayi yesibabule nayo iyidayi ye-VAT. Amadayi e-Vulcanized angasetshenziswa ukudaya ukotini, i-hemp, i-viscose kanye neminye imicu, inqubo yayo yokukhiqiza ilula, ishibhile, ingadaya nge-monochrome, kodwa futhi ingaba nombala oxubile, ukushesha okuhle elangeni, ukushesha okubi kokugqoka. Ukuntuleka kwe-chromatographic kombala obomvu, onsomi, omnyama, ofanele ukudaya umbala oqinile.
hlunga
Ngokwezimo ezahlukene zokudaya, amadayi esibabule angahlukaniswa abe amadayi esibabule ane-sodium sulphur njenge-reducing agent kanye namadayi e-VAT esibabule ane-sodium disulfite njenge-reducing agent. Ukuze asetshenziswe kalula, iqembu le-sulfonic acid lithathelwa indawo yi-sodium metabisulfite noma i-sodium formaldehyde bisulfite (igama elivamile) ukuze kutholakale idayi yesibabule encibilika emanzini, engasetshenziswa ngqo ukudaya ngaphandle kwe-reducing agent.
(1) udayi we-sulfur osebenzisa i-sodium sulphur njenge-ejenti yokunciphisa;
(2) amadayi okunciphisa i-sulfur (aziwa nangokuthi amadayi e-Haichang) anempuphu yomshwalense njenge-ejenti yokunciphisa;
(3) Idayi yesulfure ewuketshezi uhlobo olusha lwedayi yesulfure olwakhiwe futhi lwakhiqizwa ukuze lucutshungulwe kalula.
Ukusetshenziswa kwala madayi kufana namadayi e-VAT ancibilikayo, angaxutshwa ngqo namanzi ngokulingana nokucushwa, ngaphandle kokufaka ama-reducing agents, futhi kufanele kufakwe i-sodium sulphur lapho ingxenye yombala kuphela ilula. Lolu hlobo lwe-chromatography yodayi lubanzi kakhulu, kukhona obomvu okhanyayo, onsundu onsomi, oluhlaza okotshani.
Zala
Kunezindlela ezimbili zokukhiqiza udayi wesulfure ezimbonini: ① indlela yokubhaka, ama-aromatic amines ezinto ezingavuthiwe, ama-phenols noma i-nitro matter kanye ne-sulfur noma i-sodium polysulphur ekubhakeni okushisa okuphezulu, ukuze kukhiqizwe udayi wesulfure ophuzi, owolintshi, onsundu. ② Indlela yokubilisa, ama-amine, ama-phenols noma izinto ze-nitro zama-hydrocarbons aromatic aluhlaza kanye ne-sodium polysulphur ziyashiswa futhi zibiliswe emanzini noma ezinyibilikisini eziphilayo ukuze kutholakale ukudaya okumnyama, okuluhlaza okwesibhakabhaka nokuluhlaza.
imvelo
1, efana nodayi abaqondile
(1) usawoti ungasetshenziswa ukukhuthaza ukudaya.
(2), i-ejenti yokulungisa umbala we-cationic kanye ne-ejenti yokulungisa umbala kasawoti wensimbi ukuze kuthuthukiswe ukushesha.
2, efana nodayi be-VAT
(1), idayi idinga ukuncishiswa ibe yi-leachite nge-reducing agent ukuze idaye i-fiber futhi i-oxidize ku-fiber. Esikhundleni se-reducing agent enamandla, i-sodium sulphur iyi-reducing agent ebuthakathaka. Kodwa-ke, i-leaches eqondile kuma-fiber ngemva kokunciphisa iphansi kuneye-VAT dyes, futhi ukuthambekela kokuhlanganiswa kwedayi kukhulu.
(2) Ukusabela nge-asidi kungakhiqiza igesi ye-H2S, kanti ukusabela nge-acetate ye-aluminiyamu kungakhiqiza imvula yesibabule ye-aluminiyamu emnyama.
3, izinga lokushisa eliphakeme lingasetshenziswa ukuthuthukisa izinga lokusabalala kwamadayi nokuthuthukisa izinga lokungena.
