Izindlela zokuqapha zokusebenzisa i-sulfur black

i-sulfur emnyama engu-240%iyinhlanganisela yama-molecule amaningi equkethe i-sulfur eningi, isakhiwo sayo siqukethe izibopho ze-disulfide kanye nezibopho ze-polysulfide, futhi ayizinzile kakhulu. Ikakhulukazi, isibopho se-polysulfide singashintshwa sibe yi-sulfur oxide yi-oxygen emoyeni ngaphansi kwezimo ezithile zokushisa nomswakama, futhi siqhubeke nokusebenzisana nama-molecule amanzi emoyeni ukuze sikhiqize i-sulfuric acid, ngaleyo ndlela kuncishiswe amandla entambo, ukuphuka kwe-fiber, futhi yonke imicu iqhekeka ibe yimpuphu uma inzima. Ngenxa yalesi sizathu, ukuze kuncishiswe noma kuvinjelwe umonakalo wokuphuka kwe-fiber ngemva kokudaya ngedayi emnyama evulcanized, amaphuzu alandelayo kumele aqashelwe:

① Inani ledayi elimnyama elihlanganisiwe kufanele lilinganiselwe, futhi inani ledayi elikhethekile elihlanganisiwe akufanele lidlule u-700g/iphakethe. Ngenxa yokuthi inani ledayi liphezulu, amathuba okuba buthakathaka makhulu, futhi ukushesha kokudayi kuyancipha, futhi ukuwasha kunzima kakhulu.

② Ngemva kokudayiwa, kufanele ihlanzwe ngokuphelele ukuze kuvinjelwe ukuhlanzwa okungcolile, futhi umbala ontantayo entanjeni kulula ukuwubola ube yi-sulfuric acid ngesikhathi sokugcina, okwenza i-fiber iqhekeke.

③ Ngemva kokudaya, i-urea, i-soda ash kanye ne-sodium acetate kumele kusetshenziswe ekwelapheni ukushaqeka.

④ Intambo ibiliswa emanzini ahlanzekile ngaphambi kokuyidaya, futhi izinga lokuqhekeka kwentambo edaywe emanzini ahlanzekile lingcono kunele-lye ngemva kokuyidaya.

⑤ Intambo kufanele yomiswe ngesikhathi ngemva kokudaya, ngoba intambo emanzi kulula ukuyifudumeza enqubweni yenqwaba, ukuze okuqukethwe kwento yokulwa nokuqhekeka kwentambo kuncishiswe, inani le-pH lincishiswe, okungavumeli ukuqhekeka kwentambo. Ngemva kokomisa intambo, kufanele ipholiswe ngokwemvelo, ukuze izinga lokushisa lentambo likwazi ukupakishwa ngaphambi kokuba liwele ekamelweni lokushisa. Ngenxa yokuthi ayipholi ngemva kokomiswa futhi ipakishwe ngokushesha, ukushisa akulula ukukusabalalisa, okwandisa amandla okubola kwedayi kanye ne-asidi, okubangela ukuthi i-fiber ibe buthakathaka.

⑥Ukukhethwa kwamadayi amnyama alwa nokubhidlika kwe-sulphur, amadayi anjalo afakwe ku-formaldehyde kanye ne-chloroacetic acid lapho kukhiqizwa, i-methyl-chlorine ebangela ukubhidlika kwe-sulphur, ukuze ama-athomu esibabule aqiniswe kalula abe yisimo esizinzile sesakhiwo, okungavimbela ukubhidlika kwama-athomu esibabule ukuze kukhiqizwe i-acid kanye ne-fritter fiber.
