ukusetyenziswa kwesulfure emnyama ukulumkisa

isulfure emnyama 240%I-compound ye-molecular ephezulu equlethe i-sulfure eninzi, isakhiwo sayo siqulethe iibhondi ze-disulfide kunye ne-polysulfide bond, kwaye azinzile kakhulu.Ngokukodwa, ibhondi ye-polysulfide inokuthi ifakwe kwi-oksijini yesulfure emoyeni phantsi kweemeko ezithile zokushisa kunye nokufuma, kwaye idibanise ngakumbi kunye neemolekyuli zamanzi emoyeni ukuvelisa i-asidi yesulfuric, ngaloo ndlela inciphisa amandla omsonto, i-fiber brittleness, kunye ne-fiber brittleness. zonke iintsinga zi-embrittle zibe ngumgubo xa zinzulu.Ngesi sizathu, ukuze kuncitshiswe okanye kuthintelwe ukonakala kwefiber brittleness emva kokudaywa ngedayi emnyama, kufuneka kuqatshelwe la manqaku alandelayo:

① Ubungakanani bedayi emnyama evulsiwe kufuneka buncitshiswe, kwaye ubungakanani bedayi yombala okhethekileyo akufunekanga bugqithe kwi-700g/package.Ngenxa yokuba ubungakanani bedayi buphezulu, ithuba lokuqhafaza likhulu, kwaye ukukhawuleza kokudaya kuyancipha, kwaye ukuhlamba kunzima.

② Emva kokudaya, kufuneka ihlanjwe ngokupheleleyo ukukhusela ukuhlamba okungahlambulukanga, kwaye umbala ojikelezayo kumsonto kulula ukubola kwi-asidi ye-sulfuric ngexesha lokugcinwa, okwenza i-fiber brittle.

③ Emva kokudaya, i-urea, i-soda ash kunye ne-acetate yesodium kufuneka isetyenziswe kunyango oluchasayo.

④ Umsonto ubiliswe emanzini acocekileyo phambi kokuba udaywe, kwaye iqondo le-embrittlement lomsonto odaywe emanzini acocekileyo lingcono kunelo lelye emva kokudaywa.

⑤ Umsonto kufuneka womiswe ngexesha emva kokudaya, kuba umsonto omanzi kulula ukufudumeza kwinkqubo yemfumba, ukwenzela ukuba umxholo we-agent anti-brittleness uncitshiswe, ixabiso le-pH liyancitshiswa, elingenakulungele ukulwa ne-anti-brittleness. ukuba brittleness.Emva kokumisa umsonto, kufuneka upholiswe ngokwemvelo, ukwenzela ukuba ubushushu bomsonto bupakishwe ngaphambi kokuwa kwiqondo lokushisa.Ngenxa yokuba ayipholiswanga emva kokumisa kwaye ipakishwe ngokukhawuleza, ubushushu akulula ukusabalalisa, okwandisa amandla okubola kwedayi kunye ne-asidi, okubangela ukuba kunokwenzeka ukuba i-fiber ibe brittle.

⑥Ukukhethwa kwedayi ezimnyama ezichasene ne-brittle-sulphur, iidayi ezinjalo zongezwe kwi-formaldehyde kunye ne-chloroacetic acid xa kuveliswa, isiphumo se-methyl-chlorine vulcanized anti-brittle-black, ukuze iiathom zesulfure ezixutywa ngokulula zibe yimeko ezinzileyo, ethi inokuthintela i-oxidation yeeathom zesulfure ukuvelisa iasidi kunye nefiber brittle.
