Yintoni Oyaziyo Ngeedayi Zesalfure(2)?

uhlobo

Uhlobo oluphambili lweedayi zesalfure yi-sulphur black (CI sulphur black 1). Ilungiswa ngokufaka i-hydrolyzing 2, 4-dinitrochlorobenzene kunye nesisombululo se-sodium hydroxide kwisisombululo se-sodium dinitrophenol xa sele ibila, emva koko ifudunyezwe kwaye ibiliswe ngesisombululo se-sodium polysulfide kwi-molecular ratio ethile, kunye nokunciphisa kunye ne-sulfurizing reaction phantsi koxinzelelo okanye kungekho xinzelelo. Emva kokuba i-sulfurization reaction igqityiwe, yomiswa ngokuthe ngqo nge-roller dryer ukuze kufunyanwe idayi yokuqala. Emva koko ixutywa kwiidayi zorhwebo. Ngexesha le-vulcanization, umlinganiselo we-molecular we-sodium phenol kunye ne-sodium polysulfide, i-x(okt, i-sulfur index) kwi-sodium polysulfide Na2Sx kunye nobushushu be-reaction zahlukile, ukuze ukukhanya kombala wemveliso ye-sulfur black kube nomahluko wokukhanya okuluhlaza, ukukhanya okubomvu okuluhlaza kunye nokukhanya okubomvu. Eyona ngxaki inkulu yedayi emnyama yesalfure yinto yelaphu elibuthathaka. Oku kungenxa yokuba i-molecule emnyama ye-sulfure ine-sulfur esebenzayo ngendlela yee-polysulfide chains. Olu lwakhiwo lwesalfure aluzinzanga, kwaye xa idayi ifudunyezwa okanye ibekwe emoyeni oshushu nofumileyo, kulula ukuyinyibilikisa ibe yi-sulfuric acid, nto leyo ebangela ukuba ilaphu lekotoni libe buthathaka. Kwiminyaka yakutshanje, ngokuphucula inkqubo yokuvelisa i-sulfure black, i-sulfur black eqhelekileyo ipholiswa ukuya kuthi ga kwi-100℃ emva kokuba yenziwe, kwaye i-formaldehyde kunye ne-monochloroacetic acid zongezwa ukuzinzisa i-sulfur engazinzanga kwidayi, kwaye kwenziwa i-anti-brittle sulfur black daying.

Sebenzisa

Iidayi zesalfure zisetyenziselwa ukunciphisa i-leucosome enyibilikayo emanzini nge-sodium sulfide okanye i-inshurensi powder, zize zitshintshwe zibuyele kwi-original identical matter emva kokuba zifunxwe yidayi nge-oxidation okanye ezinye iziphumo, ukuze idayi ihlale kwidayi.

Faka isicelo

Iidayi zesalfure zisetyenziswa kakhulu ekudayeni iifayibha zecellulose, zisetyenziswa kakhulu kwiintambo, iimilo kunye nezinye ilaphu zoshishino kunye neendwangu ezinzima. Iindidi ezisetyenziswa kakhulu yisulfure Yuan, isulfure blue,

Isisombululo sokunciphisa

(1) Iimpawu zeearhente zokunciphisa

1. Iimpawu ze-Na2S

(1) Eyaziwa ngokuba yi-alkali sulfide, igama eliqhelekileyo elithi i-alkali enukayo, ukwakheka okusebenzayo kwe-alkali sulfide yezimboni ngokubanzi kumalunga ne-50%, kwaye imbonakalo yayo inombala otyheli-brown. Yiarhente yokunciphisa, kodwa ikwayiarhente enamandla ye-alkali, iipropati ezizinzileyo. Amandla okunciphisa e-sodium sulfide aphantsi kunalawo e-inshurensi yomgubo, i-alkalinity iphantsi kune-caustic soda kwaye ingaphezulu kune-soda ash, kwaye inomhlwa onamandla eluswini.

(2) Xa iSodium sulfide hydrolysis iye kwiNaHS, iNaHS xa incitshiswa idayi, kubonakala ukuba amandla okunciphisa iSodium sulfide anxulumene nehydrolysis yayo.

(3) I-Sodium sulfide ivelisa igesi ye-H2S xa idibana ne-asidi, ngoko ke kufuneka kuthathwe unonophelo ukuze ingadibani ne-asidi.

(4) Ukuvezwa kwe-sodium sulfide emoyeni kuya kutsala amanzi, i-C02, i-02, njl.njl., ukuze umxube osebenzayo unciphe kwaye uyeke kancinci kancinci. Ke ngoko, kufuneka ivalwe xa igcinwa, kwaye umxube wayo kufuneka uhlalutywe xa ungasasetyenziswa kwakhona ixesha elide.

(5) Isisombululo se-sodium sulfide akufuneki sibe side, kungenjalo siya kutshiswa ngumoya kwaye sinciphise ukusebenza kwaso.
