Ukuthetha ngenkqubo yokwenziwa kwelaphu le-carbon fiber e-Shenzhen

I-carbon fiberyagxothwa kubushushu obuphezulu njengento eyomeleziweyo ngeminyaka yoo-1950 kwaye yayisetyenziselwa ukuvelisa izixhobo ezijulwayo.Iintsinga zokuqala zenziwa ngokufudumeza de zenze irayon.Inkqubo ayisebenzi kakuhle, kwaye iifayili ezibangelwayo ziqulethe i-carbon ene-20 ekhulwini kuphela amandla aphantsi kunye nokuqina.Ekuqaleni kwe-1960, ukuphuhliswa kunye nokusetyenziswa kwe-polyacrylonitrile njengento eluhlaza eyenziwe nge-carbon fiber iqulethe i-55% yekhabhoni kwaye ibe nokusebenza okungcono.Indlela esisiseko yenkqubo yokuguqulwa kwe-polyacrylonitrile ngokukhawuleza yaba yindlela esisiseko yokuvelisa i-carbon fiber yokuqala.

Ngeminyaka yoo-1970, abanye abantu bazama ukucokisa nokulungisa i-carbon fiber kwi-petroleum.Le micu iqulethe malunga ne-85% yekhabhoni kwaye inamandla abalaseleyo e-flexural.Ngelishwa, banamandla okucinezela alinganiselwe kwaye abamkelwa ngokubanzi.

I-carbon fiber iyinxalenye ebalulekileyo yeemveliso ezininzi, kwaye ukusetyenziswa kwe-carbon fiber kukhula ngokukhawuleza unyaka nonyaka.

Ifiber yegraphite ibhekisa kuhlobo lwe-ultra-high modulus fiber eveliswa ngepitch yepetroleum njengemathiriyeli ekrwada.Le micu ineempawu ze-crystal-dimensional arrangement ye-crystal yesakhiwo sangaphakathi kwaye iyindlela ecocekileyo yekhabhoni ebizwa ngokuba yigraphite.

Impahla engekasilwa

Imathiriyeli ekrwada esetyenziselwa ukuvelisacarbon fiberibizwa ngokuba yi-precursor, kwaye malunga ne-90% yemveliso ye-carbon fiber ekrwada yi-polyacrylonitrile.I-10% eseleyo yenziwe ngerayon kunye ne-petroleum pitch.

Zonke ezi zixhobo ziyi-polymers eziphilayo, ezibonakaliswa ngamamolekyuli ahlanganiswe kunye nemitya emide yee-athom zekhabhoni.

Kwinkqubo yokuvelisa, iigesi ezahlukeneyo kunye nolwelo zisetyenzisiweyo, ezinye zezi zixhobo zenzelwe ukusabela ngeefibers ukuphumeza iziphumo ezithile, ezinye izinto zenzelwe, okanye musa ukusabela ukuthintela ukusabela okuthile ngemicu.Ukubunjwa ngokuchanekileyo kwezinto ezininzi kwezi nkqubo nazo zithathwa njengemfihlo yorhwebo.

inkqubo yokuvelisa

Kwinxalenye yemichiza kunye neyomatshini yecarbon fiberinkqubo yokuvelisa, i-precursor strands okanye i-fibers itsalwa kwisithando somlilo kwaye emva koko ishushu kwiqondo lokushisa eliphezulu kakhulu ngokungabikho kwe-oxygen.Ngaphandle kweoksijini, imicu ayinakutsha.Endaweni yoko, ubushushu obuphezulu bubangela ukuba iiathom zefiber zingcangcazele ngamandla de ekugqibeleni zisuswe iiathom ezingezizo ikhabhoni.Le nkqubo, ebizwa ngokuba yi-carbonization, iqulathe iinyanda ezinde zeentsinga ezidityaniswe ngokuqinileyo, zishiya kuphela iiathom ezimbalwa ezingezizo ikhabhoni.Olu lulandelelwano oluqhelekileyo lwemisebenzi yokuveliswa kwe-carbon fibers usebenzisa i-polyacrylonitrile.

1. I-Carbon fiber cloth yinto eqhubayo, kwaye kufuneka igcinwe kude nezixhobo zombane kunye nemithombo yamandla kunye namanyathelo okukhusela athembekileyo kufuneka athathwe ngexesha lokubeka kunye nokwakhiwa.

2. Ukugoba kwelaphu lekhabhoni kufuneka kugwenywe ngexesha lokugcinwa, ukuthutha kunye nokwakhiwa.

3. I-resin exhasayo ye-carbon fiber cloth kufuneka itywinwe kwaye igcinwe kude nemithombo yomlilo, ukukhanya kwelanga kunye neendawo ezinemithombo yokushisa ephezulu.

4. Indawo apho i-resin ilungiswa kwaye isetyenziswe kufuneka igcinwe ingena umoya.

5. Abasebenzi abasebenza kwisiza kufuneka bathathe amanyathelo afanelekileyo okukhusela.
