sulfur baki amfani da kariya

sulfur baki 240%wani babban sinadari ne na kwayoyin halitta mai dauke da karin sulfur, tsarinsa ya kunshi disulfide bonds da polysulfide bond, kuma ba shi da kwanciyar hankali. Musamman, haɗin polysulfide na iya zama oxidized zuwa sulfur oxide ta iskar oxygen a cikin iska a ƙarƙashin wasu yanayin zafi da zafi, da kuma ƙara yin hulɗa tare da kwayoyin ruwa a cikin iska don samar da sulfuric acid, don haka rage ƙarfin zaren, raguwar fiber, da kuma rage karfin zaren. duk zaruruwa suna shiga cikin foda lokacin da tsanani. Don wannan dalili, don rage ko hana lalacewar fiber ga lalacewa bayan rini tare da rini mai baƙar fata, dole ne a lura da waɗannan abubuwan:

① Yakamata a iyakance adadin rini na vulcanized baƙar fata, kuma adadin rini na musamman na hayar kada ya wuce 700g/kunshi. Saboda yawan rini yana da yawa, damar da za a iya fashewa yana da yawa, kuma saurin rini yana raguwa, kuma wanke yana da wuyar gaske.

② Bayan an yi rini, sai a wanke shi gaba daya don hana wankan da ba shi da kyau, kuma launin da ke kan zaren yana da sauki ya lalace ya zama sinadarin sulfuric acid yayin da ake ajiyewa, wanda hakan ke sa fiber ya karye.

③ Bayan yin rini, urea, soda ash da sodium acetate dole ne a yi amfani da shi don maganin kumburi.

④ Ana tafasa zaren a cikin ruwa mai tsafta kafin a yi rini, kuma matakin embrittlement na zaren da aka rina a cikin ruwa mai tsabta ya fi na lemun tsami bayan rini.

⑤ Ya kamata a bushe yarn a cikin lokaci bayan rini, saboda rigar yarn yana da sauƙi don zafi a cikin tsarin tari, don haka an rage abun ciki na yarn anti-brittleness wakili, an rage darajar pH, wanda ba shi da amfani ga anti- brittleness. Bayan bushewar zaren, ya kamata a sanyaya shi ta dabi'a, ta yadda za'a iya tattara zafin zaren kafin faɗuwa zuwa zafin jiki. Saboda ba a sanyaya bayan bushewa kuma nan da nan ya cika, zafi ba shi da sauƙi don rarrabawa, wanda ke ƙara kuzari ga lalatawar rini da acid, yana haifar da yiwuwar fiber ɗin ya zama raguwa.

⑥ Zaɓin dyes na anti-brittle-sulphur black dyes, irin wannan dyes an ƙara su zuwa formaldehyde da chloroacetic acid lokacin da masana'anta, sakamakon methyl-chlorine vulcanized anti-gashi-baki, don haka da sauƙi oxidized sulfur atoms zama barga tsarin jihar, wanda. zai iya hana iskar shaka na sulfur atom don samar da acid da kuma gaggautsa fiber.
