sulphur e ntšo 240%ke motsoako o phahameng oa limolek'hule o nang le sebabole se eketsehileng, sebopeho sa sona se na le li-bond tsa disulfide le li-polysulfide, 'me ha se tsitse haholo. Haholo-holo, tlamo ea polysulfide e ka oxidized ho sulfur oxide ka oksijene moeeng tlas'a maemo a itseng a mocheso le mongobo, 'me e tsoela pele ho sebelisana le limolek'hule tsa metsi moeeng ho hlahisa sulfuric acid, kahoo ho fokotsa matla a khoele, fiber brittleness, le likhoele tsohle li embrittle ho ba phofo ha tebileng. Ka lebaka lena, bakeng sa ho fokotsa kapa ho thibela tšenyo ea fiber brittleness ka mor'a ho daea ka dae e ntšo e vulcanized, lintlha tse latelang li tlameha ho hlokomeloa:

① Palo ea dae e ntšo e kentsoeng ka matla e lokela ho fokotsoa, ​​​​'me palo ea dae e khethehileng ea 'mala ha ea lokela ho feta 700g / pakete. Hobane palo ea dae e phahame, monyetla oa ho brittleness o moholo, 'me ho potlaka ha ho daea ho fokotsehile,' me ho hlatsoa ho thata haholoanyane.

② Ka mor'a ho daea, e lokela ho hlatsuoa ka ho feletseng ho thibela ho hlatsuoa ho sa hloekang, 'me 'mala o phaphametseng holim'a khoele o bonolo ho senyeha ka sulfuric acid nakong ea polokelo, e etsang hore fiber e brittle.

③ Kamora ho daea, urea, molora oa soda le acetate ea sodium e tlameha ho sebelisoa bakeng sa kalafo ea anti-brittleness.

④ Khoele e belisoa ka metsing a hloekileng pele e dauoa, 'me tekanyo ea embrittlement ea khoele e dailoeng ka metsing a hloekileng e molemo ho feta ea lye ka mor'a ho dauoa.

⑤ Khoele e lokela ho omisoa ka nako ka mor'a ho daea, hobane khoele e metsi e bonolo ho futhumatsa ka har'a ts'ebetso ea qubu, e le hore litaba tsa khoele ea anti-brittleness li fokotsehe, boleng ba pH bo fokotsehile, bo sa lumellaneng le anti-brittleness. brittleness. Ka mor'a ho omisa khoele, e lokela ho pholile ka tlhaho, e le hore mocheso oa khoele o ka kenngoa pele o oela mocheso oa kamore. Hobane ha e pholile ka mor'a ho omisa 'me hang-hang e phuthetsoe, mocheso ha o bonolo ho o aba, o eketsang matla a ho bola ha dae le asiti, e leng se etsang hore monyetla oa hore fiber e be brittle.

⑥Ho khethoa ha lidae tse ntšo tse khahlanong le brittle-sulphur, lidae tse joalo li kentsoe ho formaldehyde le chloroacetic acid ha ho etsoa, ​​​​sephetho sa methyl-chlorine vulcanized anti-brittle-black, e le hore liathomo tsa sebabole tse nang le oxid habonolo li fetohe boemo bo tsitsitseng. e ka thibela oxidation ea liathomo tsa sebabole ho hlahisa acid le brittle fiber.
