Makina opangira kaboni fiberndi apamwamba-mapetomakina osokerazopangidwa za mndandanda wa makina oluka awa.Poyerekeza ndi zida zachikhalidwe zoluka monga ulusi wa thonje ndi waya wachitsulo, makina opangira kaboni fiber ali ndi zofunikira zaukadaulo komanso zovuta kupanga ndi kupanga.
Komabe, nzosatsutsika kuti poyerekeza ndi zida zolukidwa zachikhalidwe, kuwomba kwa kaboni fiber kuli ndi mikhalidwe yabwino kwambiri, ndipo chiyembekezo chake chamtsogolo ndi chachikulu.Ichi ndi chimodzi mwazifukwa zomwe Benfa Technology yakhala ikupanga ukadaulo woluka kaboni CHIKWANGWANI kukhala njira yofunika kwambiri.
Poyerekeza ndi zida zolukidwa zakale, kodi zida za carbon fiber ndi zotani?
1. Mphamvu zolimba zolimba
Kulimba kwamphamvu kwa kaboni fiber ndi pafupifupi 2 mpaka 7 GPa, ndipo ma tensile modulus ndi pafupifupi 200 mpaka 700 GPa.Kachulukidwe kake ndi pafupifupi 1.5 mpaka 2.0 magalamu pa kiyubiki centimita, yomwe imatsimikiziridwa makamaka ndi kutentha kwa njira ya carbonization kuwonjezera pa kapangidwe ka silika woyambirira.Nthawi zambiri pambuyo kutentha 3000 ℃ graphitization mankhwala, kachulukidwe akhoza kufika 2.0 magalamu pa kiyubiki centimita.Kuphatikiza apo, kulemera kwake ndi kopepuka kwambiri, mphamvu yokoka yake yeniyeni ndi yopepuka kuposa aluminiyamu, yochepera 1/4 ya chitsulo, ndipo mphamvu yake yeniyeni ndi 20 nthawi yachitsulo.Kukula kwamafuta kowonjezera kwa kaboni fiber ndi kosiyana ndi ulusi wina, ndipo kumakhala ndi mawonekedwe a anisotropy.
2. Coefficient yaing'ono yowonjezera kutentha
Kukula kwamafuta amafuta ambiri a kaboni fiber palokha kumakhala koyipa m'nyumba (-0.5~-1.6) × 10-6/K, ndi ziro pa 200-400 ℃, ndi 1.5 × 10-6/K pomwe ndi zosakwana 1000 ℃ .Zomwe zimapangidwira zimakhala ndi coefficient yowonjezera yokhazikika ndipo ingagwiritsidwe ntchito ngati chida choyezera.
3. Good matenthedwe madutsidwe
Nthawi zambiri, matenthedwe madutsidwe a zinthu zachilengedwe ndi organic ndi osauka, koma matenthedwe madutsidwe wa mpweya CHIKWANGWANI ndi pafupi ndi zitsulo.Pogwiritsa ntchito mwayi umenewu, ukhoza kugwiritsidwa ntchito ngati zinthu zopangira kutentha kwa dzuwa ndi kutentha kwa chipolopolo chokhala ndi kutentha kofanana.
4. Yofewa ndi processability
Kuphatikiza pa mawonekedwe a zida za kaboni wamba, nsalu zopangidwa ndi kaboni fiber zimakhala ndi mawonekedwe ofewa kwambiri a anisotropic ndipo zimatha kusinthidwa kukhala nsalu zosiyanasiyana.Chifukwa cha mphamvu yokoka yaying'ono, amawonetsa mphamvu zambiri motsatira fiber axis.Mphete zowonjezeredwa ndi kaboni fiber Zipangizo zophatikizika ndi utomoni wa okosijeni zili ndi zisonyezo zapamwamba kwambiri zamphamvu zenizeni komanso modulus yeniyeni pakati pa zida zomwe zilipo kale.
5. Kutsika kwa kutentha kwapansi
Mpweya wa kaboni uli ndi kukana kwabwino kwa kutentha kwapansi, monga kusakhazikika pansi pa kutentha kwa nayitrogeni wamadzimadzi.
6. Kukana dzimbiri
Mpweya wa carbon umalimbana bwino ndi dzimbiri ku solvents wamba, ma acid, ndi alkalis.Simasungunuka kapena kutupa.Imakhala ndi dzimbiri ndipo ilibe vuto la dzimbiri.
7. Good kuvala kukana
Mpweya wa carbon ndi zitsulo sizimavalidwa kawirikawiri popakana.Mpweya wa kaboni umagwiritsidwa ntchito m'malo mwa asibesitosi kuti apange zinthu zogundana kwambiri, zomwe zakhala zikugwiritsidwa ntchito ngati zida zama brake pa ndege ndi magalimoto.
8. Kukana kutentha kwakukulu
Kuchita kwa carbon fiber kumakhala kokhazikika pansi pa 400 ° C, ndipo palibe kusintha kwakukulu ngakhale pa 1000 ° C.Kutentha kwapamwamba kwa zipangizo zophatikizika makamaka kumadalira kutentha kwa matrix.Kutentha kwanthawi yayitali kwa zinthu zophatikizika ndi utomoni ndi pafupifupi 300 ℃, ndipo kukana kwa kutentha kwa ceramic-based, carbon-based and metal-based composite materials kungafanane ndi carbon fiber yokha.Zida za carbon fiber composite zimagwiritsidwa ntchito kwambiri muzamlengalenga ngati zida zolimbana ndi kutentha kwambiri.
9. Zabwino kwambiri
Mpweya wa carbon uli ndi ubwino wabwino kwambiri (chimodzi mwa zizindikiro za fineness ndi chiwerengero cha magalamu a utali wa mamita 9000), nthawi zambiri pafupifupi 19 magalamu, ndi mphamvu yolimba yofikira 300 kg pa micron.Zida zina zochepa zili ndi zinthu zabwino kwambiri monga carbon fiber.
10. Kukanika kopanda mphamvu komanso kosavuta kuwononga
Makutidwe ndi okosijeni amapezeka pansi pa zochita za asidi amphamvu, mphamvu ya electromotive ya carbon fiber ndi yabwino, ndipo mphamvu ya electromotive ya aluminium alloy ndi yoipa.Pamene carbon fiber composite zipangizo ntchito osakaniza zotayidwa aloyi, zitsulo carbonization, carburization ndi electrochemical dzimbiri zidzachitika.Chifukwa chake, ulusi wa kaboni uyenera kusinthidwa musanagwiritse ntchito.
