Sei shinda ichiita brittle mushure mekudhayiwa neSulfur Black dhayi? Ndingazvidzivirira sei? Chii chatinofanira kungwarira pakuita izvi?

Sei shinda yekuruka ichiita brittle mushureSulfur Black Br dhayi coloring? Ndingazvidzivirira sei? Chii chatinofanira kungwarira pakuita izvi?

Dhayi ine sulfide dema ndeyepamusoro molecular compound ine sarufa yakawanda, chimiro chayo chine disulfide bonds 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, uyezve kupindirana nemamorekuru emvura ari mumhepo kugadzira sulfuric acid, nokudaro kuderedza kusimba kweshinda inotenderera, fiber brittleness, uye mafiibha ese anopfumbuka kuita upfu kana akanyanya.

Nechikonzero ichi, kuti uderedze kana kudzivirira fiber brittleness kukuvara mushure mekuruka shinda neSulfur Black Br dhayi, zvinotevera zvinofanirwa kutariswa kune:①Huwandu hweSulfur Black Br dhayi inofanirwa kuve shoma, uye huwandu hwesiriki yakakosha dhayi haifanire kudarika 700g / package. Nokuti kuwanda kwedhayi kwakakwirira, mukana wekuputika wakakura, uye kukurumidza kwekudhaya kunoderedzwa, uye kushambidza kunonyanya kuoma.②Mushure mekunge ruvara runofanira kushambidzwa zvakakwana, usageze wakachena, ruvara runoyangarara pamutsara weshinda inotenderera iri nyore kuparara kuita sulfuric acid mukuchengetedza uye kuita kuti fiber brittle.③Mushure mekupenda, urea, soda ash uye sodium acetate inofanira kushandiswa pakurapa brittleness.④Shinda inorukwa inofashaidzwa mumvura yakachena isati yaiswa ruvara, uye mwero weshinda inoruka mushure mekuongororwa uri nani pane weshinda yakabikwa.⑤Iyo yekuruka shinda inofanirwa kuomeswa nenguva mushure mekupenda, nekuti shinda yakanyorova inongopisa panguva yekututira, iyo inoderedza zvirimo zve-anti-brittleness agent uye pH kukosha kweshinda inotenderera, iyo isingafadzi kune anti-brittleness.

Mushure mekuomeswa, shinda inoruka inofanira kutonhodzwa zvega, kuitira kuti tembiricha yeshinda inoruka igone kurongedzerwa isati yawira kune kamuri tembiricha. Nemhaka yokuti haina kutonhodzwa mushure mekuoma uye kurongedzerwa pakarepo, kupisa hakusi nyore kugovera, izvo zvinowedzera simba rekuparara kwedhayi uye asidi, zvichiita kuti mukana wekuti fiber iite brittle.

Kusarudzwa kweAnti-brittle-Sulfur Black Br madhayi, madhayi akadaro akawedzerwa kune formaldehyde uye chloroacetic acid pakugadzira, iyo inoguma methyl - chlorine vulcanized anti-brittle-black, kuitira kuti maatomu ari nyore oxidized sulfur ave yakagadzikana mamiriro, ayo anogona kudzivirira oxidation yemaatomu esarufa kuti abudise. asidhi uye brittle fiber.
