Kodi kapangidwe kabwino ka kaboni ka chimango chanjinga ndi chiyani?

Mpweya ndiwowoneka bwino kwambiri ngati chinthu choyamba kusankha pankhani yomanga chimango chodziwika bwino ndipo motero pali mafelemu owopsa a njinga za kaboni kunja uko ndipo palibe 'njinga yabwino kwambiri ya kaboni'. njinga, pali zinthu zina zomwe muyenera kuziganizira posankha kavalo watsopano - geometry, ndondomeko ndi mtengo wa ndalama kukhala mfundo zazikulu.

Monga njinga yopirira, njinga yamapiri ya Ewig idapangidwa kuti ikhale yomasuka kukwera kwa nthawi yayitali, koma yogwira ntchito mokwanira kuti mutha kuyenda mtunda wautali.Momwemonso, chimango cha kaboni chimakhala ndi kusakanikirana kovutirapo kwa mawonekedwe a chubu, kuti apereke kuuma komwe kukufunika - monga kuzungulira chubu lamutu ndi bulaketi yapansi - komanso kusinthasintha komwe kulibe, monga pampando.

Pofotokoza za carbon fiber mu njinga, ndikofunika kumvetsetsa kuti mapeto ake ndi chinthu chopangidwa kuchokera ku carbon fibers okha ndi utomoni, womwe umakhala ngati guluu kapena chinthu chomangira kuti chigwire ndi kulimbikitsa ulusi pamodzi.Woonda kwambiri kuposa tsitsi la tsitsi, makulidwe a ulusi wa kaboni amasiyana kwambiri.Zingwe za carbon fiber (zingwe) zimamangirizidwa pamodzi mu 'chikoka', chomwe nthawi zambiri chimalukidwa kukhala mapepala onga nsalu.Utoto nthawi zambiri umakhala wofooka komanso wosasinthika wa chigawocho ndipo cholinga chake ndikupangitsa kuti zingwezo zikhale zomangika moyandikana momwe zingathere.

Mpweya wa kaboni womwe umagwiritsidwa ntchito panjinga nthawi zambiri umakhala wosalunjika ndipo mbali yomwe amawunjirira ndiyofunikira kwambiri.Kuyika ulusi pamakona ake kumapanga mphamvu ndi kuuma komwe kumafunikira.Mwachitsanzo, ngati mphamvu zomwe zimayikidwa pa chimango zikutsutsana ndi momwe zimakhalira, zimakhala zamphamvu komanso zosagwirizana ndi mphamvu.Komabe, ngati ulusiwo utayikidwa pakona pomwe ulusi sungathe kutsutsa mphamvuyo, umasinthasintha.Mfungulo pakuyika ndikukhazikitsa kuuma ndi mphamvu komwe kumafunikira pomwe pakufunika kusinthasintha m'malo ena pomwe pakufunika - zomwe makampani nthawi zambiri amazitcha 'kutsata'.Mbali zina za chimango, kapena mafelemu a kaboni otsika mtengo, atha kugwiritsa ntchito 'wolukidwa' wa carbon-fibre, yomwe imapereka mawonekedwe ofanana mbali zonse momwe imayalira.

Ubwino wa njinga ya carbon ndi chiyani?

Ubwino waukulu wa zinthuzo ndikuti pakuuma kopatsidwa, mpweya wa kaboni umakhala wopepuka kwambiri kuposa aluminiyamu, chitsulo, kapena titaniyamu.Kachulukidwe kakang'onoku kumatanthauzanso kuti mafelemu a kaboni amagwira ntchito yabwinoko kugwedezeka (m'malo motumiza) kugwedezeka kwa msewu, komwe kumapangitsa kuyenda bwino.

Chinthu choyamba chimene anthu amaganiza ndi kulemera, ndipo inde mpweya wa carbon mu njinga umapanga mafelemu opepuka kwambiri.Mtundu wa fiber wa zinthu umalola omanga chimango kuti asinthe kuuma ndi kutsata pogwirizanitsa zigawo za kaboni m'njira zosiyanasiyana.ndi kutsatira mu chubu mpando ndi amakhala kwa wokwera chitonthozo.

Zimapangitsa kuyenda kosavuta, komasuka, Phindu lalikulu kwa okwera omwe sapikisana nawo ndi chitonthozo cha chimango cha njinga ya kaboni, foloko yanjinga ya kaboni imapindula ndi kugwedera konyowa komwe kumapangitsa kuyenda bwino.

Ndi amphamvu ndi cholimba kwambiri.Technical kusintha mu yokhotakhota ndi epoxy, ndi luso okonza kumanga mu mphamvu m'madera chimango kumene chofunika kwambiri, zikutanthauza mpweya tsopano angagwiritsidwe ntchito kumanga chimango cholimba kwambiri njinga.M'malo mwake, mafelemu apanjinga ya kaboni awonetsedwa kuti amaposa aloyi pakuyezetsa labu ndipo mutha kugulanso njinga yamoto yotsika kaboni yokhala ndi kukana bwino.

Ndi chinthu chokhazikika kwambiri.Mafelemu apanjinga za Carbon fiber m'msewu anali sachedwa kuwonongeka ndi UV, koma iyi sivutonso chifukwa mafelemu abwino omwe amapangidwa masiku ano amakhala ndi zolimbitsa thupi za UV.Komanso, musade nkhawa mukamagwiritsa ntchito kutsuka panjinga pagalasi lanu latsopanoli - poyerekeza ndi chitsulo kapena aluminiyamu, kaboni ndi chinthu chopanda mpweya ndipo sichingatengeke ndi dzimbiri kapena kuwonongeka kwa mchere.
