Inkangeleko yei-sulfur emnyamayikristale emnyama eqhekekileyo, kwaye umphezulu wekristale unamanqanaba ahlukeneyo okukhanya (utshintsho ngokutshintsha kwamandla). Isisombululo samanzi lulwelo olumnyama, kwaye i-sulphur emnyama kufuneka inyibilikiswe ngesisombululo se-sodium sulfide.
I-pro Sulfur black crystal yidayi eyenziweyo yosapho lwedayi yesulfur. Isetyenziswa kakhulu kwishishini lempahla yokudaya imicu yekotoni njengoko inika umbala omnyama onzulu. I-Sulfide Black Crystal yaziwa ngokuhlala kwayo inombala okhawulezayo, oko kuthetha ukuba ayizukunyamalala nasemva kokuhlanjwa rhoqo okanye ukuchatshazelwa lilanga. Ikwabiza kancinci kwaye ifumaneka kakhulu kwimarike.
Inkqubo yokukhupha i-sulphur emnyama isekelwe kwi-2,4-dinitrochlorobenzene, efakwa kwi-hydrolyzed phantsi kweemeko ze-alkaline ukuze kufunyanwe ityuwa ye-2,4-dinitrophenol sodium, ethi emva koko yongezwe kwisisombululo se-sodium polysulfide ukuze ivulcanization. Emva kwe-oxidation, ukuhluzwa, imveliso egqityiweyo iyomiswa.
I-sulphur black isetyenziswa kakhulu ekudayini umqhaphu, i-hemp, i-viscose kunye neendwangu zayo ezixutyiweyo. Uninzi lweendwangu ze-denim (ezimnyama) ezidumileyo ekhaya nakwamanye amazwe zenziwe ngentambo emnyama eyolukiweyo kunye nentambo emhlophe. I-sulphur black ineebhondi ezininzi ze-disulfide emva kokuba incitshisiwe yi-sodium sulfide, kwaye kulula ukuyi-oxidized ukunciphisa amandla eendwangu ezidayiweyo, oko kukuthi, ukuphuka. Ukuze uthintele umonakalo ophukayo, kufuneka unikele ingqalelo kwezi ngongoma:
1. Lawula ubungakanani besalfure emnyama. Okukhona ubuninzi besalfure emnyama, kokukhona kunokwenzeka ukuba kubekho umonakalo oqhekekayo.
2. Hlamba kakuhle ukuze unciphise umbala odadayo kumthwalo.
3. Sebenzisa izongezo zeTaikoo Oil ukuthintela ukuqhekeka.
4. Ukukhuhla ngamanzi amatsha ngaphambi kokuba udaywe. Intambo exutywe namanzi ovavanyo emva kokudaywa inomgangatho ongcono wokukrazula kune-lye.
5. Yomisa ngexesha emva kokudaya ukuze kuncitshiswe umxholo wezinto ezilwa nokuqhekeka okubangelwa kukuqokelelana okumanzi.
