isulfure emnyama 240%iyinhlanganisela yamangqamuzana ephezulu equkethe isibabule esengeziwe, isakhiwo sayo siqukethe amabhondi e-disulfide namabhondi e-polysulfide, futhi ayizinzile kakhulu.Ikakhulukazi, isibopho se-polysulfide singafakwa i-oxidized ku-sulfur oxide nge-oxygen emoyeni ngaphansi kwezimo ezithile zokushisa nomswakama, futhi iqhubeke nokusebenzisana nama-molecule amanzi emoyeni ukuze kukhiqizwe i-sulfuric acid, ngaleyo ndlela kunciphise amandla entambo, i-fiber brittleness, kanye yonke imicu i-embrittle ibe yimpushana uma ibucayi.Ngalesi sizathu, ukuze kuncishiswe noma kuvinjwe ukulimala kwe-fiber brittleness ngemuva kokudaywa ngodayi omnyama ovuthululiwe, amaphuzu alandelayo kufanele aqashelwe:
① Inani likadayi omnyama oshisiwe kufanele likhawulelwe, futhi inani lodayi okhethekile owenziwe i-mercerized akufanele lidlule u-700g/iphakheji.Ngenxa yokuthi inani ledayi liphezulu, ithuba lokukhwabanisa likhulu, futhi ukusheshisa ukudaya kuyancipha, futhi ukugeza kunzima kakhulu.
② Ngemva kokudaya, kufanele igezwe ngokugcwele ukuze kuvinjelwe ukugezwa okungahlanzekile, futhi umbala ontantayo entanjeni kulula ukubola ube yi-sulfuric acid ngesikhathi sokugcinwa, okwenza i-fiber ibe brittle.
③ Ngemuva kokudaya, i-urea, i-soda ash ne-sodium acetate kufanele isetshenziselwe ukwelashwa okuqeda ukubola.
④ Intambo ibiliswa emanzini ahlanzekile ngaphambi kokudaywa, futhi izinga le-embrittlement lentambo edaywe emanzini ahlanzekile lingcono kunalelo le-lye ngemva kokudaya.
⑤ Intambo kufanele yomiswe ngesikhathi ngemuva kokudaywa, ngoba intambo emanzi kulula ukuyishisa enqubweni yenqwaba, ukuze okuqukethwe kwe-agent anti-brittleness kuncishiswe, inani le-pH liyancipha, elingahambisani ne-anti-brittleness. ubuqhwaga.Ngemuva kokumisa intambo, kufanele ipholile ngokwemvelo, ukuze izinga lokushisa lentambo lingahlanganiswa ngaphambi kokuwela ekamelweni lokushisa.Ngenxa yokuthi ayipholisiwe ngemva kokoma futhi ipakishwa ngokushesha, ukushisa akulula ukusabalalisa, okwandisa amandla okubola kwedayi kanye ne-asidi, okubangela ukuthi kungenzeka ukuthi i-fiber ibe brittle.
⑥Ukukhethwa kodayi abamnyama be-anti-brittle-sulphur, odayi abanjalo bengezwe ku-formaldehyde ne-chloroacetic acid lapho kwenziwa, umphumela we-methyl-chlorine vulcanized anti-brittle-black, ukuze ama-athomu esibabule afakwe i-oxidized abe yisimo sesakhiwo esizinzile. ingavimbela i-oxidation yama-athomu esulfure ukukhiqiza i-asidi ne-fiber brittle.
