Tsarin masana'anta na takarda aramid

Tsarin samar da gyare-gyare na fibers aramid:

Polymerization: A cikin mataki na farko, ana jujjuya filayen aramid cikin ƙaƙƙarfan foda mai ƙyalƙyali. Wannan abu yana da babban thermal da sinadaran Properties na para aramid zaruruwa. Koyaya, ba ta mallaki abubuwan ƙarfafa zaren ko ɓangaren litattafan almara ba. Ana iya amfani da wannan foda mai kyau don haɓaka kaddarorin abubuwan filastik.

Kadi: A mataki na biyu na filayen aramid, ana narkar da polymer a cikin sulfuric acid don samar da maganin crystal ruwa. Daga baya, an zana maganin a cikin filaye masu kyau, kowannensu yana da diamita na 12 μ M. Tsarin siliki shine 100% subcrystalline, tare da sarƙoƙi na kwayoyin halitta daidai da axis fiber. Wannan babban ɗabi'a yana ba Twaron filament halaye masu kyau iri-iri.

Short fiber: gajeriyar fiber na wucin gadi ko gajeriyar fiber, wanda ake sarrafa shi ta hanyar murƙushe zaren sannan a bi da shi da wakili na gamawa. Bayan bushewa, yanke zarurukan zuwa tsayin manufa sannan a haɗa su.

Juyawa cikin ɓangaren litattafan almara: Don samar da ɓangaren litattafan almara, filaye na aramid sun fara yanke zaren sannan su dakatar da shi a cikin ruwa don maganin fibrosis. Sannan a hada shi kai tsaye a sayar da shi a matsayin jika, ko kuma a bushe a bushe a busasshe shi a matsayin busasshen ɓangaren litattafan almara don sayarwa.
