Wazi Ntoni NgeDayi Yesulfure(1)?

Idayi zesulfure ziidayi ezinyityilikiswa kwisalfure yealkali.Zisetyenziswa ikakhulu ukudaya iintsinga zomqhaphu kwaye zingasetyenziselwa amalaphu adityanisiweyo womqhaphu/ivithamin.Iindleko ziphantsi, idayi ngokuqhelekileyo iyakwazi ukuhlamba kunye nokukhawuleza, kodwa umbala awukhanyisi ngokwaneleyo.Iintlobo ezisetyenziswa ngokuqhelekileyo ziSulfur Blue 7,Ubomvu beSulfur 14 I-Sulfur Black Bluishandnjalo njalo.Idayi zesulfure ezinyibilikayo ziyafumaneka ngoku.Idayi eyenziwe kukusabela kwe-vulcanization yee-amines, phenols, okanye iikhompawundi ze-nitro ze-hydrocarbons ezinuka kamnandi ezinesulfure okanye i-sodium polysulphur,

okukhethekileyo

Idayi zesulfure azinyibiliki emanzini, kwaye isalfure yesodium okanye ezinye izinto zokunciphisa zisetyenziselwa ukunciphisa idayi kwi-leucochromes enyibilikayo.Inobudlelwane nefiber kwaye ingcolise ifayibha, kwaye emva koko ibuyisela imeko yayo enganyibilikiyo nge-oxidation kunye nokulungiswa kwifiber.Ngoko ke idayi yesulfure ikwayidayi yeVAT.Idayi evulcanized ingasetyenziselwa ukudaya umqhaphu, i-hemp, i-viscose kunye nezinye iifayibha, inkqubo yokwenziwa kwayo ilula, indleko ephantsi, inokudaywa i-monochrome, kodwa ingadityaniswa nombala odibeneyo, ukukhawuleza okulungileyo ekukhanyeni kwelanga, ukukhawuleza ukunxiba.Ukungabikho kweChromatographic yombala obomvu, omfusa, omnyama, olungele ukudaya umbala oqinileyo.

uhlobo

Ngokweemeko ezahlukeneyo zokudaya, iidayi zesulfure zinokwahlulwa zibe ziidayi zesulfure ezinesulfure yesodium njenge-arhente yokunciphisa kunye nedayi ye-VAT yesulfure ene-sodium disulfite njenge-arhente yokunciphisa.Ukuze kusetyenziswe lula, iqela le-sulfonic acid lifakwe endaweni ye-sodium metabisulfite okanye i-sodium formaldehyde bisulfite (igama eliqhelekileyo) ukufumana idayi yesulfure enyibilikayo emanzini, engasetyenziselwa ngokuthe ngqo ukudaya ngaphandle kokunciphisa i-agent.

(1) iidayi zesulfure zisebenzisa isalfure yesodium njenge-agent yokunciphisa;

(2) idayi zokunciphisa isulfure (ekwabizwa ngokuba yi-Haichang dyes) kunye nomgubo we-inshurensi njenge-arhente yokunciphisa;

3

Ukusetyenziswa kweedayi ezinjalo kufana nedayi ye-VAT e-soluble, enokuthi ihlanjululwe ngokuthe ngqo ngamanzi ngokuhambelana nokulungelelaniswa, ngaphandle kokongeza ii-agent zokunciphisa, kunye ne-sodium sulfure kufuneka yongezwe xa kuphela inxalenye yombala ilula.Olu hlobo lwechromatography yedayi lubanzi, kukho umbala obomvu oqaqambileyo, omfusa obomvu, uHu green.

Zala

Zimbini iindlela zokuvelisa iidayi zesulfure kwimizi-mveliso: ① indlela yokubhaka, imathiriyeli enevumba elimnandi, i-phenols okanye i-nitro matter kunye nesalfure okanye i-sodium polysulphur kubushushu obuphezulu bokubhaka, ukuze kuveliswe idayi emthubi, i-orenji, ne-brown sulfur.② Indlela yokubilisa, ii-amines, i-phenols okanye izinto ze-nitro ze-hydrocarbon ekrwada enevumba elimnandi kunye ne-sodium polysulphur ziyafudunyezwa kwaye zibiliswe emanzini okanye kwizinyibilikisi zendalo ukuze kufunyanwe ukudaya okumnyama, okuluhlaza okwesibhakabhaka nokuluhlaza.

indalo

1, efana nedayi ngqo

(1) ityuwa inokusetyenziselwa ukukhuthaza ukudaya.

(2), i-agent yokulungisa umbala we-cationic kunye ne-agent yensimbi yokulungisa umbala wetyuwa ukuphucula ukukhawuleza.

2, efana nedayi yeVAT

(1), idayi idinga ukuncitshiswa kwi-leachite kunye ne-agent yokunciphisa ukudaya i-fiber kunye ne-oxidize kwi-fiber.Esikhundleni se-ejenti yokunciphisa eqinile, i-sulfure ye-sodium i-ejenti yokunciphisa ebuthathaka.Nangona kunjalo, ipropati ethe ngqo ye-leaches kwi-fibers emva kokunciphisa iphantsi kuneedayi ze-VAT, kwaye ukuthambekela kokuhlanganiswa kwedayi kukhulu.

(2) Ukusabela nge-asidi kunokuvelisa igesi ye-H2S, kwaye impendulo nge-acetate ye-aluminiyam inokuvelisa imvula emnyama ye-aluminium sulfure.

3, ubushushu obuphezulu bunokusetyenziswa ukuphucula izinga lokusasazwa kwedayi kunye nokuphucula inqanaba lokungena.
