Uburyo bwo kwirinda gukoresha sulfure black

umukara wa sulfure 240%ni ikintu kinini gifite molekile nyinshi kirimo sulfure nyinshi, imiterere yacyo irimo imigozi ya disulfide n'imigozi ya polysulfide, kandi ntihindagurika cyane. By'umwihariko, imigozi ya polysulfide ishobora guhindurwa ogisijeni ya sulfur na ogisijeni iri mu kirere munsi y'ubushyuhe n'ubushuhe runaka, kandi igakomeza gukorana na molekile z'amazi mu kirere kugira ngo ikore aside sulfurike, bityo bikagabanya imbaraga z'ubudodo, ububobere bwa fibre, kandi imigozi yose igahinduka ifu iyo ikomeye. Kubera iyo mpamvu, kugira ngo tugabanye cyangwa hirindwe kwangirika kwa fibre nyuma yo gusigwa irangi ry'umukara rya vulcanized, ingingo zikurikira zigomba kwitabwaho:

① Ingano y'irangi ry'umukara rya vulcanized igomba kuba nke, kandi ingano y'irangi ryihariye rya mercerized ntigomba kurenza 700g ku ipaki. Kubera ko ingano y'irangi ari nyinshi, amahirwe yo kwangirika ni menshi, kandi irangi riragabanuka, kandi kumesa biragoye cyane.

② Nyuma yo gusiga irangi, igomba kozwa neza kugira ngo hirindwe kozwa nabi, kandi ibara rireremba ku budodo ryoroshye kubora rikavamo aside sulfure mu gihe cyo kubika, ibyo bigatuma fibre icika intege.

③ Nyuma yo gusiga irangi, urea, soda ash na sodium acetate bigomba gukoreshwa mu kuvura ububobere.

④ Ubudodo butekwa mu mazi meza mbere yo kubusiga irangi, kandi urwego rwo gushwanyagurika rw'ubudodo busizwe mu mazi meza ni rwiza kuruta ubwa lye nyuma yo kubusiga irangi.

⑤ Ubudodo bugomba kumanurwa mu gihe nyuma yo gusigwa irangi, kuko ubudodo butose bworoshye gushyushya mu gihe cyo gusigwa, kugira ngo ingano y'ubudodo igabanya ububobere, pH igabanuke, ibyo bikaba bidatuma ububobere bugabanuka. Nyuma yo kumisha ubudodo, bugomba gukonjeshwa mu buryo busanzwe, kugira ngo ubushyuhe bw'ubudodo bushobore gupfunyikwa mbere yo kumanuka bugera ku bushyuhe bw'icyumba. Kubera ko budakonjeshwa nyuma yo kumisha kandi bugahita bupakirwa, ubushyuhe ntiburoroshye gukwirakwira, ibyo byongera ingufu zo kubora kw'irangi na aside, bigatuma fibre ishobora kwangirika.

⑥Itoranywa ry'irangi ry'umukara rirwanya brittle-sulphur, bene ayo marangi yongewe kuri formaldehyde na aside chloroacetic mu gihe cyo gukora, methyl-chlorine vulcanized anti-brittle-black, bityo atome za sulphur zoroshye gukurwamo oxidized ziba imiterere ihamye, ishobora gukumira oxidization ya atome za sulphur kugira ngo ikore aside na fibre brittle.
