Ukukhuluma ngenqubo yokukhiqiza indwangu ye-carbon fiber e-Shenzhen

I-carbon fiberyaxoshwa ekushiseni okuphezulu njengento eqinisiwe ngawo-1950 futhi yasetshenziselwa ukukhiqiza izesekeli ze-missile.Imicu yokuqala ikhiqizwa ngokushisisa kuze kube yi-rayon.Inqubo ayisebenzi kahle, futhi imicu ewumphumela iqukethe ikhabhoni enamaphesenti angaba ngu-20 kuphela amandla aphansi nokuqina.Ekuqaleni kwawo-1960, ukuthuthukiswa nokusetshenziswa kwe-polyacrylonitrile njengento eluhlaza eyenziwe i-carbon fiber iqukethe ama-55% ekhabhoni futhi ibe nokusebenza okungcono.Indlela eyisisekelo yenqubo yokuguqulwa kwe-polyacrylonitrile ngokushesha yaba indlela eyisisekelo yokukhiqizwa kwe-carbon fiber yokuqala.

Ngawo-1970, abanye abantu bazama ukucwenga nokucubungula i-carbon fibre evela ku-petroleum.Le micu iqukethe cishe u-85% wekhabhoni futhi inamandla amahle kakhulu okuguquguquka.Ngeshwa, banamandla okucindezela alinganiselwe futhi awamukelwa kabanzi.

I-Carbon fiber iyingxenye ebalulekile yemikhiqizo eminingi, futhi ukusetshenziswa kwe-carbon fiber kukhula ngokushesha unyaka nonyaka.

I-graphite fiber ibhekisela ohlotsheni lwe-ultra-high modulus fiber ekhiqizwa nge-petroleum pitch njengento eluhlaza.Le micu inezici ze-crystal-dimensional crystal arrangement yesakhiwo sangaphakathi futhi iwuhlobo oluhlanzekile lwekhabhoni olubizwa nge-graphite.

impahla eluhlaza

Impahla eluhlaza esetshenziselwa ukukhiqizai-carbon fiberibizwa ngokuthi i-precursor, futhi cishe u-90% wezinto ezingavuthiwe zokukhiqiza i-carbon fibre yi-polyacrylonitrile.I-10% esele yenziwe nge-rayon ne-petroleum pitch.

Zonke lezi zinto zingama-polymer aphilayo, abonakala ngama-molecule ahlanganiswe ndawonye ngezintambo ezinde zama-athomu ekhabhoni.

Enqubweni yokukhiqiza, kusetshenziswa amagesi ahlukahlukene noketshezi, ezinye zalezi zinto zenzelwe ukusabela ngemicu ukuze kuzuzwe imiphumela ethile, ezinye izinto zenzelwe, noma zingaphenduli ukuvimbela ukusabela okuthile ngemicu.Ukwakheka okuqondile kwezinto eziningi kulezi zinqubo nakho kubhekwa njengemfihlo yokuhweba.

inqubo yokukhiqiza

Engxenyeni yamakhemikhali neyemishini yei-carbon fiberinqubo yokukhiqiza, imicu eyandulela noma imicu idonselwa esithandweni bese ishiselwa ekushiseni okuphezulu kakhulu ngokungabikho kwe-oxygen.Ngaphandle komoyampilo, imicu ayikwazi ukusha.Esikhundleni salokho, izinga lokushisa eliphezulu lenza ama-athomu e-fiber adlidlize ngamandla kuze kube yilapho ekugcineni ekhishwa ama-athomu angewona awekhabhoni.Le nqubo, ebizwa nge-carbonization, iqukethe izinyanda ezinde zemicu ebambene ngokuqinile, okushiya ama-athomu ambalwa angewona awekhabhoni asele.Lokhu ukulandelana okujwayelekile kokusebenza kokukhiqizwa kwe-carbon fibers kusetshenziswa i-polyacrylonitrile.

1. Indwangu ye-carbon fibre iwukusetshenziswa kwe-conductive, futhi kufanele igcinwe kude nezinto zikagesi nemithombo yamandla futhi izinyathelo zokuvikela ezinokwethenjelwa kufanele zithathwe ngesikhathi sokubekwa nokwakhiwa.

2. Ukugoba kwendwangu ye-carbon kufanele kugwenywe ngesikhathi sokugcinwa, ukuthutha nokwakhiwa.

3. I-resin esekelayo yendwangu ye-carbon fiber kufanele ivalwe futhi igcinwe kude nemithombo yomlilo, ilanga eliqondile kanye nezindawo ezinemithombo yokushisa ephezulu.

4. Indawo lapho i-resin ilungiselelwa futhi isetshenziswe kufanele igcinwe inomoya omuhle.

5. Abasebenzi abasebenza esizeni kufanele bathathe izinyathelo zokuvikela ezihambisanayo.
