Uphawu lweMveliso:I-sulfure emnyama ayinyibiliki emanzini okanye i-ethanol, ibonakala iluhlaza-mnyama kwisisombululo se-sodium sulfide, ibonakala i-bluish xa ifakwe i-caustic soda kwisisombululo somnyama wesulfure, kwaye ibonakala i-precipitate eluhlaza kunye ne-hydrochloric acid I-miniature e-soluble kwi-acid sulfuric ebandayo, Ijike ibe yimvula eluhlaza okwesibhakabhaka emva kokufudumala, ize ijike ibemnyama-blowu xa igcina ubushushu.Idayi zesulfure zithatha kakuhle idayi kunye nokudaya kwinqanaba.
Ukucaciswa kweMveliso
Amanye Amagama: Sulphur Black 1
Amandla: 240%;220%;200%;180%;150%;100%……
Imbonakalo: Iiflakes ezinkulu ezikhanyayo eziMnyama okanye iigranules
Ukupakisha: 25kgs PP Bag / Kraft Bag / Iron Drum
Imibala: BR 522 (Ithoni eBomvu) kunye ne-B 521 (Ithoni eGreenish)
Isicelo:Isetyenziselwa ukudaya iCotton, iJeans, iDenim njalo njalo....
Indlela yokuvelisa:yenziwe nge-2, i-4-dinitrochlorobenzene kunye nesisombululo se-sodium hydroxide kwimeko yokubilisa kufutshane, i-hydrolysis kwisisombululo se-sodium dinitrophenol, kwaye emva koko kunye nesisombululo se-sodium polysulfide yamanzi ngokwe-molecular ratio ukufudumeza ukubilisa, phantsi koxinzelelo okanye ukungabikho koxinzelelo, ukunciphisa kunye ukuphendula isulfure kwaye ilungisiwe.
Ukudaywa kunye nokulungiswa kwesulphur emnyama br:Ukudaya kunye nokulungiswa kwe-sulphur black br, idayi emnyama yesulfure ayinakunyibilika emanzini.Ngexesha lokudaya, i-sodium sulfide okanye ezinye ii-agent zokunciphisa ziya kusetyenziswa ukunciphisa idayi kwi-leucosomes e-soluble.Inobudlelwane nefayibha kwaye idayi ifayibha, kwaye emva koko iphinde ibuyisele imeko yayo yokunganyibiliki emva kwe-oxidation kunye nophuhliso lombala kwaye luzinze kwifiber.
Ugcino&uthutho:I-Sulfur Black BR kufuneka igcinwe emthunzini, kwindawo eyomileyo & nengena umoya.Kuphephe ukudityaniswa neekhemikhali ze-oxidizing kunye nezinto ezinokutsha ze-organic.Yigcine kude nelanga elithe ngqo, ubushushu, iintlantsi kunye namadangatye avulekileyo.Yiphathe ngononophelo imveliso kwaye uphephe ukonakalisa iphakheji.ukugcinwa, ukupakishwa, ukuthuthwa, ukulayisha,
bonelela ngeyona nkonzo ingcono, YANHUI DYES uyazingisa ekwaneliseni abathengi.
