Yini Oyaziyo Ngamadayi Esibabule (1)?

odayi besulfure bangodayi abancibilika ku-alkali sulphur.Zisetshenziselwa ikakhulukazi ukudaya imicu kakotini futhi zingasetshenziselwa izindwangu ezixutshwe ukotini/amavithamini.Izindleko ziphansi, udayi ngokuvamile uyakwazi ukugeza futhi ngokushesha, kodwa umbala awukhanyi ngokwanele.Izinhlobo ezivame ukusetshenziswaSulfur Blue 7,Isibabule Esibomvu 14 I-Sulfur Black Bluishandnjalonjalo.Odayi besulfure abancibilikayo sebeyatholakala.Udayi owenziwe ukusabela kwe-vulcanization kwama-amine, ama-phenol, noma izinhlanganisela ze-nitro zama-hydrocarbon anephunga elimnandi elinesulfure noma i-sodium polysulphur,

okukhethekile

odayi besulfure abancibiliki emanzini, futhi isulfure yesodium noma ezinye izinto ezinciphisayo zisetshenziselwa ukunciphisa odayi kuma-leucochromes ancibilikayo.Inobungane ku-fiber futhi ingcolisa i-fiber, bese ibuyisela isimo sayo esingancibiliki nge-oxidation kanye nokulungiswa ku-fiber.Ngakho udayi wesulfure nawo uwudayi we-VAT.Amadayi avulcanized angasetshenziselwa ukudaya ukotini, i-hemp, i-viscose neminye imicu, inqubo yayo yokukhiqiza ilula, izindleko eziphansi, ingadaywa nge-monochrome, kodwa futhi ingaba nombala oxubile, ukushesha okuhle kwelanga, ukusheshisa ukugqoka.Ukuntuleka kweChromatographic kombala obomvu, onsomi, omnyama, ofanele ukudaya umbala oqinile.

hlunga

Ngokwezimo ezihlukene zokudaya, odayi besulfure bangahlukaniswa babe odayi besulfure abanesulfure ye-sodium njenge-ejenti yokunciphisa kanye nodayi be-VAT besulfure abane-sodium disulfite njenge-ejenti yokunciphisa.Ukuze kusetshenziswe kalula, iqembu le-sulfonic acid lishintshwa nge-sodium metabisulfite noma i-sodium formaldehyde bisulfite (igama elivamile) ukuthola udayi wesulfure oncibilikayo emanzini, ongasetshenziswa ngokuqondile ukudaya ngaphandle kokunciphisa i-ejenti.

(1) odayi besulfure abasebenzisa isulfure ye-sodium njenge-ejenti yokunciphisa;

(2) odayi bokunciphisa isibabule (owaziwa nangokuthi odayi base-Haichang) abanempushana yomshwalense njenge-ejenti yokunciphisa;

(3) Udayi wesulfure owuketshezi uwuhlobo olusha lukadayi wesibabule othuthukisiwe futhi okhiqizwa ukuze ucutshungulwe kalula.

Ukusetshenziswa kwamadayi anjalo kufana namadayi e-VAT ancibilikayo, angahlanjululwa ngokuqondile ngamanzi ngokulingana nokucushwa, ngaphandle kokwengeza ama-ejenti okunciphisa, futhi esinye isibabule se-sodium kufanele sengezwe uma kuphela ingxenye yombala ilula.Lolu hlobo lwe-chromatography kadayi lubanzi ngokuqhathaniswa, kukhona okubomvu okukhanyayo, onsundu onsomi, u-Hu green.

Zala

Kunezindlela ezimbili zokukhiqiza ezimbonini zikadayi wesulfure :① indlela yokubhaka, izinto ezingavuthiwe zama-amine, amaphenoli noma i-nitro matter nesibabule noma i-sodium polysulphur ezingeni lokushisa eliphezulu lokubhaka, ukuze kukhiqizwe odayi abaphuzi, osawolintshi, abansundu nesibabule.② Indlela yokubilisa, ama-amine, ama-phenol noma izinto ze-nitro zama-hydrocarbon anephunga eliluhlaza kanye ne-sodium polysulphur ziyashiswa futhi zibiliswe emanzini noma ezincibilikilweni zemvelo ukuze kutholwe ukudaya okumnyama, okuluhlaza okwesibhakabhaka nokuluhlaza.

imvelo

1, efana nodayi abaqondile

(1) usawoti ungasetshenziswa ukuthuthukisa ukudaya.

(2), i-ejenti yokulungisa umbala we-cationic kanye ne-ejenti yokulungisa umbala kasawoti wensimbi ukuze kuthuthukiswe ukushesha.

2, okufana nodayi be-VAT

(1), udayi udinga ukwehliswa ube yi-leachite ene-ejenti yokunciphisa ukudaya i-fiber futhi i-oxidize ku-fiber.Esikhundleni se-ejenti yokunciphisa eqinile, isulfure ye-sodium iyi-ejenti yokunciphisa ebuthakathaka.Kodwa-ke, impahla eqondile yokucwiliswa kwamafayibha ngemva kokwehliswa iphansi kunaleyo yodayi be-VAT, futhi ukuthambekela kokuhlanganisa udayi kukhulu.

(2) Ukusabela nge-asidi kungakhiqiza igesi ye-H2S, futhi ukusabela nge-acetate ye-aluminiyamu kungaveza imvula yesibabule ye-aluminium emnyama.

3, izinga lokushisa eliphakeme lingasetshenziswa ukuthuthukisa izinga lokusabalalisa likadayi futhi kuthuthukiswe izinga lokungena.
