Nzira dzekudzivirira kushandisa sarufa nhema

sarufa nhema 240%imhando yakakura yemamorekuru ine sarufa yakawanda, chimiro chayo chine ma bond e disulfide uye ma bond e polysulfide, uye haina kugadzikana zvakanyanya. Kunyanya, polysulfide bond inogona kuoxidized kuita sarufa oxide neokisijeni iri mumhepo pasi pemamiriro ekupisa nehunyoro, uye inobatanidzwa nemamorekuru emvura ari mumhepo kugadzira sulfuric acid, nokudaro ichideredza simba reshinda, fragility yefiber, uye ma fiber ese anopwanyika kuita upfu kana hwakakomba. Nechikonzero ichi, kuitira kuderedza kana kudzivirira fragility yefiber mushure mekudhayiwa ne vulcanized black dye, zvinhu zvinotevera zvinofanirwa kucherechedzwa:

① Huwandu hwedhayi nhema yakasanganiswa ne vulcanized hunofanira kuderedzwa, uye huwandu hwedhayi yemavara akasiyana-siyana yakasanganiswa ne mercerized hahufanirwe kudarika 700g/pakeji. Nekuti huwandu hwedhayi hwakakura, mukana wekuti dhayi isashande zvakanaka wakakura, uye kukurumidza kwedhayi kwakaderera, uye kuwacha kwakaoma.

② Mushure mekudhaya, inofanira kugezwa zvizere kudzivirira kusukwa kusina kuchena, uye ruvara rwunoyangarara pashinda yacho runoora nyore nyore kuita sulfuric acid panguva yekuichengeta, izvo zvinoita kuti shinda yacho iputsike.

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

④ Shinda inobikwa mumvura yakachena isati yadhayiwa, uye mwero wekusviba kweshinda yakadhayiwa mumvura yakachena uri nani pane welye mushure mekudhayiwa.

⑤ Shinda inofanira kuomeswa nenguva mushure mekudhayiwa, nekuti shinda yakanyorova iri nyore kupisa mukuita kwemurwi, kuitira kuti huwandu hweshinda hudzikise, pH inodzikiswa, izvo zvisingakonzeri kuputika. Mushure mekuomesa shinda, inofanira kutonhodzwa zvakasikwa, kuitira kuti tembiricha yeshinda ikwanise kurongedzwa isati yasvika patembiricha yemukamuri. Nekuti haitonhodzwi mushure mekuomeswa uye yakarongedzwa pakarepo, kupisa hakusi nyore kugovera, izvo zvinowedzera simba rekuora kwedhayi neasidhi, zvichiita kuti faibha iome.

⑥Kusarudzwa kwemadhayi matema anodzivirira kupwanyika kwesimbi, madhayi akadaro akawedzerwa ku formaldehyde ne chloroacetic acid pakugadzirwa, methyl-chlorine vulcanized anti-brittle-black inoguma, kuitira kuti maatomu e sulfur anonyungudika nyore nyore ave mamiriro akagadzikana echivakwa, izvo zvinogona kudzivirira kupwanyika kwemaatomu e sulfur kuti agadzire acid ne brittle fiber.
