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 kune sulfur oxide neokisijeni mumhepo pasi peimwe tembiricha uye humidity mamiriro, uye zvakare kupindirana nemamorekuru emvura ari mumhepo kugadzira sulfuric acid, nokudaro kuderedza simba reshinda, brittleness yefiber, uye mafiibha ese ari embrittle kuita upfu kana zvakakomba. 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 we brittleness wakakura, uye kukurumidza kudhaya 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 Iyo shinda inofanira kuomeswa nenguva mushure mekudhayiwa, nekuti shinda yakanyorova iri nyore kupisa mumurwi wekuita, kuitira kuti zvinyorwa zvemucheka anti-brittleness agent zvideredzwe, iyo pH kukosha inoderedzwa, iyo isingakodzeri kurwisa- 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 acid pakugadzira, inokonzeresa methyl-chlorine vulcanized anti-brittle-black, kuitira kuti maatomu ari nyore oxidized sulfur ave yakagadzikana mamiriro, ayo inogona kudzivirira oxidation yesarufa maatomu kuburitsa asidhi uye brittle fiber.
