Kulankhula za njira yopangira nsalu za carbon fiber ku Shenzhen

Mpweya wa carbonidawomberedwa pakutentha kwambiri ngati zida zolimbikitsidwa m'zaka za m'ma 1950 ndipo zidagwiritsidwa ntchito kupanga zida za mizinga.Ulusi woyamba umapangidwa ndi kutentha mpaka kupanga rayon.Njirayi ndiyosagwira ntchito, ndipo ulusi wake umakhala ndi mpweya wokhala ndi mphamvu zochepera 20 zokha komanso zouma.Kumayambiriro kwa zaka za m'ma 1960, chitukuko ndi kugwiritsidwa ntchito kwa polyacrylonitrile monga zopangira zopangidwa ndi carbon fiber zimakhala ndi 55% carbon ndipo zimakhala bwino.Njira yoyambira yosinthira polyacrylonitrile mwachangu idakhala njira yoyambira yopanga mpweya wa kaboni.

M’zaka za m’ma 1970, anthu ena anayesa kuyenga ndi kukonza mpweya wa carbon fiber kuchokera ku petroleum.Ulusiwu uli ndi pafupifupi 85% ya kaboni ndipo uli ndi mphamvu zosinthika kwambiri.Tsoka ilo, ali ndi mphamvu zochepa zopondereza ndipo samavomerezedwa kwambiri.

Mpweya wa carbon ndi gawo lofunika kwambiri lazinthu zambiri, ndipo kugwiritsa ntchito mpweya wa carbon kukukula mofulumira chaka ndi chaka.

Ulusi wa graphite umatanthawuza mtundu wa ultra-high modulus fiber opangidwa ndi phula la petroleum ngati zopangira.Ulusiwu umakhala ndi mawonekedwe amtundu wa kristalo wa mawonekedwe atatu amkati ndipo ndi mawonekedwe oyera a carbon otchedwa graphite.

zopangira

Zomwe zimagwiritsidwa ntchito popangacarbon fiberimatchedwa kalambulabwalo, ndipo pafupifupi 90% ya carbon fiber kupanga zopangira ndi polyacrylonitrile.10% yotsalayo imapangidwa ndi rayon ndi petroleum pitch.

Zonsezi ndi ma polima achilengedwe, omwe amadziwika ndi mamolekyu omangidwa pamodzi ndi zingwe zazitali za maatomu a carbon.

Popanga, mipweya yosiyanasiyana ndi zakumwa zimagwiritsidwa ntchito, zina mwazinthuzi zimapangidwira kuti zigwirizane ndi ulusi kuti zikwaniritse zotsatira zake, zida zina zimapangidwira, kapena osachitapo kanthu kuti ateteze machitidwe ena ndi ulusi.Mapangidwe enieni azinthu zambiri munjirazi amawonedwanso ngati chinsinsi chamalonda.

kupanga ndondomeko

Mu mankhwala ndi makina gawo lacarbon fiberkupanga, zingwe zoyambira kapena ulusi zimakokedwa mu ng'anjo ndikutenthedwa ndi kutentha kwambiri popanda mpweya.Popanda mpweya, ulusi sungathe kuwotcha.M'malo mwake, kutentha kwakukulu kumapangitsa kuti maatomu a fiber azigwedezeka mwamphamvu mpaka pamapeto pake maatomu omwe si a kaboni achotsedwa.Njira imeneyi, yotchedwa carbonization, imakhala ndi mitolo yayitali ya ulusi yomwe imatsekedwa mwamphamvu, ndikusiya maatomu ochepa omwe si a carbon.Izi ndi mmene zinayenderana ntchito yopanga mpweya ulusi ntchito polyacrylonitrile.

1. Nsalu ya carbon fiber ndi chinthu chowongolera, ndipo iyenera kusungidwa kutali ndi zida zamagetsi ndi magwero amagetsi ndipo njira zodzitetezera ziyenera kuchitidwa panthawi yoika ndi kumanga.

2. Kupindika kwa nsalu ya carbon kuyenera kupewedwa panthawi yosungira, yoyendetsa ndi kumanga.

3. Utomoni wothandizira wa nsalu ya carbon fiber uyenera kusindikizidwa ndikusungidwa kutali ndi kumene kuli moto, kuwala kwa dzuwa ndi malo omwe ali ndi kutentha kwakukulu.

4. Malo amene utomoni umakonzedwa ndi kugwiritsidwa ntchito ayenera kukhala ndi mpweya wabwino.

5. Ogwira ntchito pamalowo ayenera kutsatira njira zodzitetezera.
