Wazi Ntoni NgeDayi Yesulfure(2)?

zala

Uhlobo oluphambili lweedayi zesulfure zimnyama sulfure (CI sulphur black 1).Ilungiswa nge-hydrolyzing 2, i-4-dinitrochlorobenzene kunye nesisombululo se-sodium hydroxide kwisisombululo se-sodium dinitrophenol xa sisondele ukubila, emva koko ukufudumeza kunye nokubilisa ngesisombululo se-sodium polysulfide kwi-molecular ratio ethile, kunye nokunciphisa kunye ne-sulfurizing reaction phantsi koxinzelelo okanye akukho xinzelelo.Emva kokuba i-sulfurization reaction igqityiwe, yomiswa ngokuthe ngqo nge-roller dryer ukufumana idayi yokuqala.Emva koko idityaniswe kwiidayi zorhwebo.Ngexesha le-vulcanization, umlinganiselo wemolekyuli we-sodium phenol kunye ne-sodium polysulfide, i-x (oko kukuthi, isalathisi sesulfure) kwi-sodium polysulfide Na2Sx kunye nobushushu bokuphendula kuyahluka, ukuze ukukhanya kombala wemveliso emnyama yesulfure ibe nokwahlukana kokukhanya okuluhlaza, okuluhlaza. ukukhanya okubomvu kunye nokukhanya okubomvu.Intlupheko enkulu yedayi emnyama yesulfure yinto yengubo enqabileyo.Oku kungenxa yokuba imolekyuli emnyama yesulfide iqulethe isulfure esebenzayo ngohlobo lwamatyathanga epolysulfide.Olu qulunqo lwesulfure aluzinzile, kwaye xa idayi ifudumala okanye ibekwe emoyeni oshushu kunye nomswakama, kulula ukudibanisa i-asidi ye-sulfuric, okubangelwa ukunyanzeliswa kwengubo yekotoni.Kwiminyaka yakutshanje, ngokuphucula inkqubo yokuveliswa kwesulfure emnyama, i-sulphur emnyama eqhelekileyo ipholile ukuya kwi-100 ℃ emva kokwenziwa, kwaye i-formaldehyde kunye ne-monochloroacetic acid zongezwa ukuzinzisa isulfure engazinzanga kwidayi, kunye ne-anti-brittle sulphur emnyama. ukudaya kwenziwa.

Sebenzisa

Idayi zesulfure zisetyenziselwa ukuncitshiswa kwi-leucosome enyibilikayo emanzini kunye ne-sodium sulfide okanye umgubo we-inshorensi, kwaye emva koko itshintshelwe kwinto enemibala enganyibilikiyo emva kokufunxwa yidayi nge-oxidation okanye ezinye iziphumo, ukuze idayi igxininiswe kwidayi. .

Faka isicelo

Idayi zesulfure zisetyenziswa kakhulu ekudayeni iifiber zeselulosi, ezisetyenziswa ikakhulu kwimisonto, imilo kunye namanye amalaphu amashishini kunye namalaphu anzima.Ezona ntlobo zisetyenziswa kakhulu yiSulfur Yuan, sulfur blue,

Isisombululo sokunciphisa

(1) Iipropati zee-arhente zokunciphisa

1. Iipropati ze-Na2S

(1) Ikwaziwa ngokuba yialkali sulfide, igama eliqhelekileyo ialkali enukayo, ukwakhiwa okusebenzayo kwealkali yealkali sulfide ngokuqhelekileyo malunga nama-50%, kwaye inkangeleko iluqilima olutyheli-mdaka.I-arhente yokunciphisa, kodwa kunye ne-alkali eqinile, iipropati ezizinzileyo.Umthamo wokunciphisa we-sodium sulfide ungaphantsi kunomgubo we-inshurensi, i-alkalinity iphantsi kune-caustic soda kwaye inkulu kunothuthu lwesoda, kwaye inomhlwa oqinileyo eluswini.

(2) I-sodium sulfide hydrolysis kwi-NaHS, i-NaHS ekunciphiseni idayi, kunokubonwa ukuba umthamo wokunciphisa i-sodium sulfide uhambelana ne-hydrolysis yayo.

3

(4) Ukubonakaliswa kwe-sodium sulfide emoyeni kuya kuthabatha amanzi, i-C02, i-02, njl., ukwenzela ukuba ukubunjwa okusebenzayo kuyancipha kwaye ngokuthe ngcembe kwehluleka.Ngoko ke, kufuneka itywinwe xa igcinwe, kwaye ukubunjwa kwayo kufuneka kuhlalutywe xa ingaphinda isetyenziswe ixesha elide.

(5) Isisombululo se-sodium sulfide akufanele sibe side, ngaphandle koko siya kuba ne-oxidized emoyeni kwaye sinciphise ukusebenza kwayo.

sebenzisa
