Ke hobane'ng ha khoele e robeha ka mor'a ho dauoa ka dae ea Sulfur Black? Nka e thibela joang? Re lokela ho ela hloko eng ts'ebetsong?

Ke hobane'ng ha khoele e ohlang e brittle ka mor'aSulfur Black Brdae mebala? Nka e thibela joang? Re lokela ho ela hloko eng ts'ebetsong?

Dae e ntšo ea sulfide ke motsoako o phahameng oa limolek'hule o nang le sebabole se eketsehileng, sebopeho sa eona se na le li-bond tsa disulfide le li-polysulfide bonds, 'me ha e tsitsa haholo. Haholo-holo, bond polysulfide ka oxidized ho oxide e sebabole ka oksijene moeeng tlas'a maemo a itseng a mocheso le mongobo, 'me ka ho eketsehileng sebelisana le limolek'hule tsa metsi moeeng ho hlahisa sulfuric acid, kahoo ho fokotsa matla a khoele ohla, faeba brittleness, le likhoele tsohle ke embrittle ka phofo ha boima. Ka lebaka lena, e le ho fokotsa kapa ho thibela tšenyo ea fiber brittleness ka mor'a ho ohla khoele kaSulfur Black Brdae, lintlha tse latelang li tlameha ho eloa hloko:

① Palo ea dae ea Sulfur Black Br e lokela ho fokotsoa, ​​'me palo ea dae e khethehileng ea silika ha ea lokela ho feta 700g/package. 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 hore 'mala o hlatsuoe ka ho feletseng, u se ke ua hlatsoa o hloekile,' mala o phaphametseng holim'a khoele e ohlang ho bonolo ho senyeha ka sulfuric acid nakong ea polokelo le ho etsa hore fiber e brittle.

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

④ Khoele e ohlang e belisoa ka metsing a hloekileng pele e ka tšeloa mebala, 'me tekanyo ea khoele e ohiang ka mor'a tlhahlobo e betere ho feta ea khoele e phehiloeng.

⑤ Khoele e ohlang e lokela ho omisoa ka nako ka mor'a ho penta, hobane khoele e metsi e futhumetse feela nakong ea ts'ebetso ea stacking, e fokotsang litaba tsa anti-brittleness le pH ea boleng ba khoele e ohlang, e sa rateheng ho thibela brittleness. Ka mor'a ho omisoa, khoele e ohiang e lokela ho pholile ka mokhoa oa tlhaho, e le hore mocheso oa khoele e ohiang o khone ho paka pele o oela mocheso oa kamore.

Hobane ha e pholile ka mor'a ho omisoa le ho phutheloa hang-hang, 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. Khetho ea anti-brittle-Sulphur Black Brdae, lidae tse joalo li kenyellelitsoe ho formaldehyde le chloroacetic acid ha ho etsoa tlhahiso, sephetho sa methyl - chlorine vulcanized anti-brittle-black, e le hore liathomo tsa sebabole tse nang le oxidized habonolo li fetohe boemo bo tsitsitseng ba sebopeho, bo ka thibelang oxidation ea liathomo tsa sebabole ho hlahisa acid le brittle fiber.
