sulfur dema kushandisa precautions

sarufa nhema 240%ikemikari yepamusoro yemamorekuru ine sarufa yakawanda, chimiro chayo chine disulfide bond uye polysulfide bond, uye haina kugadzikana zvakanyanya. Kunyanya, iyo polysulfide bond inogona kuve oxidized kuita sulfur oxide neokisijeni mumhepo pasi peimwe tembiricha uye humidity mamiriro, uyezve kupindirana nemamorekuru emvura ari mumhepo kugadzira sulfuric acid, nokudaro kuderedza kusimba kweshinda, fiber brittleness, uye mafiber ese ari embrittle kuita upfu kana yakakomba. Nechikonzero ichi, kuti udzikise kana kudzivirira kukuvara kwefiber brittleness mushure mekudhayiwa nedhayi dema, zvinotevera zvinofanirwa kucherechedzwa:

① Huwandu hwedhayi dema hwakasvibiswa hunofanirwa kuganhurirwa, uye huwandu hwedhayi yakasarudzika haifanire kudarika 700g/pasuru. Nemhaka yokuti huwandu hwedhayi hwakakwirira, mukana wekuputika wakakura, uye kukurumidza kwedhayi kunoderedzwa, uye kushambidza kunonyanya kuoma.

② Mushure mekudhayiwa, inofanira kushambidzwa zvakakwana kudzivirira kushambidzika kusina kuchena, uye ruvara runoyangarara pashinda rwuri nyore kuparara kuita sulfuric acid panguva yekuchengetedza, izvo zvinoita kuti fiber iite brittle.

③ Mushure mekudhaya, urea, soda ash uye sodium acetate inofanira kushandiswa pakurapa brittleness.

④ Shinda inofashaidzwa mumvura yakachena isati yadhayiwa, uye dhigirii reshinda yeshinda yakadhayiwa mumvura yakachena iri nani pane yelye mushure mekudhayiwa.

⑤ Mutsara unofanirwa kuomeswa munguva mushure mekudhayiwa, nokuti jira rakanyorova riri nyore kupisa mumurwi, kuitira kuti zvinyorwa zvemucheka anti-brittleness agent zvideredzwe, iyo pH inokosha inoderedzwa, iyo isingaiti kune anti-brittleness. Mushure mekuomesa shinda, inofanira kutonhodzwa zvakasununguka, kuitira kuti kutonhora kweshinda kugone kuiswa mumapuranga kusati kwawira kune tembiricha yekamuri. Nemhaka yokuti haina kutonhora mushure mekuoma uye pakarepo yakarongedzwa, kupisa hakusi nyore kugovera, izvo zvinowedzera simba rekuparara kwedhayi uye asidi, zvichiita kuti mukana wekuti fiber iite brittle.

⑥Kusarudzwa kwe-anti-brittle-sarufa madhayi matema, madhayi akadaro akawedzerwa kune formaldehyde uye chloroacetic asidhi pakugadzira, inoguma methyl-chlorine vulcanized anti-brittle-black, kuitira kuti nyore oxidized sulfur maatomu ave yakagadzikana mamiriro ezvinhu, anogona kudzivirira iyo sulfure fiber uye brittle oxidation.
