momwe mungayang'anire chimango cha njinga ya kaboni kuti ming'alu |Mtengo wa EWIG

Kaya ngozi ichitika pamsewu kapena pamunda, chinthu choyamba muyenera kuteteza ndi chitetezo chanu, ndikutsatiridwa ndi zida.Pambuyo potsimikizira kuti muli pamalo otetezeka, masitepe oti muwone ngati zida zowonongeka ndizofunika kwambiri.Ndiye tinganene bwanji ngati a29inch carbon fiber mountain bike frameali ndi zoopsa zosweka kapena zobisika poyamba?Kenako, zomwe zili m'nkhaniyi ndikuphunzitsani momwe mungaweruzire thanzi la chimango kuchokera kuzinthu zosiyanasiyana monga mpweya wa carbon, aluminium alloy ndi titaniyamu alloy.

Kwa mafelemu achitsulo, ngati foloko yakutsogolo yawonongeka pambuyo pa kugundana kutsogolo, chimangocho chidzawonongekanso.Ngakhale chimango cha carbon fiber sichili chotsimikizika, chiyenera kuyang'aniridwa malinga ndi momwe zinthu zilili.Chifukwa chimango ndi mphanda wakutsogolo zimawonongeka palimodzi, zimatengera kudumpha kwa zinthu za chimango, zomwe zimatsimikizira ngati chubu cha chimango ndi chopunduka kapena kupitilira malire ake zotanuka pa kugunda.

Mpweya wa kaboni umapangidwadi ndi zida zophatikizika za kaboni, ndipo kusiyana pakati pawo kumadalira mtundu wa mpweya wa kaboni womwe umagwiritsidwa ntchito, momwe amadulira komanso utomoni wogwiritsidwa ntchito.Ma Snowboards amapangidwanso ndi zinthu zophatikizika.Ichi ndi chitsanzo chabwino, chifukwa matabwa a chipale chofewa opangidwa ndi zinthu zophatikizika amapindika mopanikizika, pomwe mafelemu a njinga nthawi zambiri amakhala osiyana.Ndi wamphamvu kwambiri, kotero pamene pansi pa kupsyinjika, Nthawi zambiri sizodziwikiratu.Chifukwa chake, ngaticarbon fiber chimangoimayikidwa ndi mphamvu yokwanira yothyola foloko yakutsogolo, chimangocho chikhoza kuonongeka ngakhale palibe kuwonongeka kowonekera.

Pankhani ya kuwonongeka kwa carbon fiber frame, pali mwayi wina woti nsalu yamkati yamkati ya carbon yasweka, ndipo maonekedwewo sakuwoneka kuti awonongeka.Izi nthawi zambiri zimatchedwa "kuwonongeka kwakuda."Mwamwayi, "mayeso a ndalama" angagwiritsidwe ntchito kuti azindikire ngati izi zikuchitika.

"Njira yoyezera ndalama" ndiyo kugwiritsa ntchito m'mphepete mwa ndalamayo kugunda chimango, makamaka kuzungulira chubu chapamwamba, tiyi ya chubu lamutu, ndi chubu chapansi cha chimango.Phokoso la kugogoda limafanizidwa ndi phokoso la kugogoda pafupi ndi chomverera m'makutu.Ngati phokoso limakhala lopanda phokoso kwambiri, zimatsimikizira kuti chimango cha carbon fiber chawonongeka.Komabe, ziyenera kukumbukiridwa kuti kupititsa mayeso a ndalama sikukutanthauza kuti chimango ndi chotetezeka, ndipo kuwunikanso kwaukadaulo kwa X-ray ndikofunikira kuti mutsimikizire mtengo waumoyo wa chimango.

Momwe mungayang'anire ming'alu ndi ndalama?

Timayendera mtundu uwu pang'ono.Timatsuka chimango ndikuyang'anitsitsa ming'alu.Mayeso a tap tap ndi othandiza kwambiri.Ndipo kumadera omwe amawoneka okayikitsa koma osamveka mosiyana kwambiri ndi kuyesa kwapampopi, timatsuka penti ndikuchotsa ndikunyowetsa mpweya wowonekera ndi acetone.Mutha kuwona mwachangu pomwe acetone imakhala yonyowa mumng'alu pamene imatuluka.Zofanana ndi kuyesa kwa ufa wa utoto koma wopanda mitundu yonyezimira.Nthawi zina, monga ndi zoyambira zolemera / zodzaza zomwe zikuwonetsa kung'ambika kakang'ono, timalimbikitsa wokwerayo kuti aziyang'anitsitsa ndikuwona ngati ming'aluyo ikukula.Chizindikiro chaching'ono chimayikidwa kumapeto kwa mng'alu ndi lumo.90% ya nthawiyo, ndi utoto wosweka womwe sukula.10% ya nthawi yomwe imakula pang'ono pang'ono kenako timayika penti ndikuwulula ming'alu yomwe ikuyamba kukula.

Momwe mungayang'anire ming'alu ndiukadaulo wa X-ray?

Mukakhala pangozi, pakhoza kukhala mng'alu wowonekera pamwamba panjinga ya carbon fiber, zomwe zimapangitsa kuti zikhale zosatetezeka kuti zigwiritsidwe ntchito ndipo zimafuna kukonzedwa kapena (nthawi zambiri) zosinthidwa.Kung'ung'udza kwina sikungawonekere pamtunda ndipo kungayambitse kugwiritsa ntchito njinga mopanda chitetezo.njinga ya carbon fiberkapena osati?

Njira imodzi ndiyo kugwiritsa ntchito luso lamakono la X-ray - makamaka X-ray tomography - yomwe imadziwikanso kuti microCT kapena CT scanning.Njirayi imagwiritsa ntchito ma X-ray kuyang'ana mkati mwa ziwalo ndikuwona ngati pali ming'alu kapena zolakwika zopanga.Nkhaniyi ikufotokoza mwachidule nkhani yomwe CT idagwiritsidwa ntchito pojambula ming'alu pawiri zowonongekanjinga za carbon fiber.

Momwe mungatetezere chimango cha carbon fiber?

Palibe kutentha kwakukulu

Ngakhale mpweya wa carbon umakhala ndi kutentha kwambiri, kuwala kwa dzuwa kwa nthawi yayitali kumatha kuwononga utoto wakunja, choncho chonde musawonetse njingayo kumalo otentha kwambiri kapena kuyiyika pamalo otentha kwambiri m'nyumba kapena m'galimoto.

Sambani nthawi zonse

Nthawi zonse kuyeretsa chimango ndi mwayi kuyendera njinga.Mukayeretsa chimango, muyenera kuyang'ana ngati chawonongeka kapena chaphwanyidwa.Osagwiritsa ntchito mankhwala osungunulira omwe si akatswiri kuti ayeretse chimango.Ndibwino kuti mugwiritse ntchito akatswiri oyeretsa njinga.Musagwiritse ntchito asidi amphamvu, alkali amphamvu (otsukira, thukuta, mchere) ndi mankhwala ena oyeretsa omwe ali ndi mankhwala kuti muyeretse galimoto ya carbon fiber kuti musawononge utoto wa chimango.
