maitiro ekutarisa kabhoni bhasikoro furemu kune makatsemuka |EWIG

Kunyangwe tsaona ikaitika mumugwagwa kana pamunda, chinhu chekutanga chaunofanirwa kuchengetedza kuchengetedza kwako, kuchiteverwa nemidziyo.Mushure mekusimbisa kuti uri munzvimbo yakachengeteka, matanho ekutarisa kana midziyo yakakuvadzwa yakakosha.Saka tinogona sei kufanotaura kana iyo29inch carbon fiber gomo bhasikoro furemuine ngozi dzakatsemuka kana dzakavanzwa pakutanga?Tevere, zviri muchinyorwa chino ndezvekukudzidzisa maitiro ekutonga hutano hwefuremu kubva kune zvakasiyana zvinhu zvakaita secarbon fiber, aluminium alloy uye titanium alloy.

Pamafuremu esimbi, kana forogo yepamberi yakuvadzwa mushure mekudhumhana kwemberi, furemu yacho ichakuvadzwawo.Kunyangwe iyo kabhoni fiber furemu isina chokwadi, inofanirwa kuongororwa zvinoenderana nemamiriro ezvinhu.Nekuda kwekuti furemu neforogo yekumberi zvakakuvadzwa pamwechete, zvinonyanya kuenderana neiyo ductility yefuremu zvinhu, izvo zvinotarisa kuti furemu chubhu yakagomara kana kupfuura elastic muganho panguva yekudhumhana.

Iyo kabhoni fiber furemu inogadzirwa chaizvo nekabhoni fiber composite zvinhu, uye mutsauko uripo pakati pawo unoenderana nerudzi rwekabhoni fiber inoshandiswa, iyo stacking kutungamira uye resin inoshandiswa.Snowboards inogadzirwawo nezvinhu zvakasanganiswa.Uyu muenzaniso wakanaka, nekuti mabhodhi echando akagadzirwa nezvinhu zvakasanganiswa anokotama pasi pekumanikidzwa, nepo mafuremu ebhasikoro kazhinji anopesana.Iyo yakasimba kwazvo, saka kana iri pasi pekumanikidzwa, Kazhinji haisi pachena.Naizvozvo, kana iyocarbon fiber frameinoiswa pasi pesimba rinokwanisa kupaza forogo yepamberi, furemu inogona kukuvara kunyangwe pasina kukuvara kunoonekwa.

Panyaya yekukuvara kwekabhoni fiber frame, pane imwe mukana wekuti mukati memukati wakadzika wemucheka wekabhoni wakatsemuka, uye chitarisiko hachiratidzike chakakanganisika.Iyi mamiriro inowanzonzi "dark damage."Neraki, iyo "coin test" inogona kushandiswa kuona kana izvi zvichiitika.

Iyo "coin test method" ndeyekushandisa mupendero wemari kubaya furemu, kunyanya kutenderedza chubhu yekumusoro, tei yechubhu yemusoro, nechubhu yepasi pefuremu.Ruzha rwekugogodza runofananidzwa neruzha rwekugogodza pedyo nehedhiseti.Kana ruzha rwanyanya kugomara, zvinoratidza kuti iyo kabhoni fiber furemu yakakuvadzwa.Nekudaro, zvakakosha kucherechedza kuti kupasa bvunzo dzemari hazvireve kuti furemu yakachengeteka, uye imwezve nyanzvi furemu X-ray yekuongorora inodiwa kuti pakupedzisira uone kukosha kwehutano.

Nzira yekutarisa kuputika nemari?

Isu tinoita rudzi urwu rwekuongorora zvishoma.Isu tinochenesa furemu uye tinotarisa zvakanyanya kune makatsemuka.A coin tap test inoshanda zvakanyanya.Uye kune idzo nzvimbo dzinoita senge dzisina chokwadi asi dzisinganzwike dzakasiyana zvakanyanya kubva kubvunzo yepombi, tinoisa jecha pendi uye clearcoat tonyorovesa iyo yakafumurwa kabhoni neacetone.Iwe unogona kukurumidza kuona panogara acetone yakanyorova mukutsemuka sezvainoputika.Zvakafanana nebvunzo yeupfu-dhayi asi isina mavara anopenya.Mune zvimwe zviitiko, senge inorema primer / mafirita anoratidza kutsemuka kudiki, isu tinokurudzira mutasvi kuti arambe akatarisa pairi uye ona kana mutswe uchikura.Mucherechedzo diki unoiswa kumagumo ekutsemuka nebadza.90% yenguva, ipendi yakatsemuka isingakure.10% yenguva iyo inokura zvishoma uye isu tobva taisa jecha pasi pepende uye kazhinji tinoratidza kutsemuka kwechimiro kuri kutanga kukura.

Nzira yekutarisa sei kutsemuka neX-ray tekinoroji?

Paunenge waita tsaona, panogona kuve nekutsemuka kunoonekwa pamusoro peiyocarbon fiber bhasikoro, izvo zvinoita kuti isachengeteke kushandiswa uye ingave inoda kugadziriswa kana (munguva zhinji) kutsiva.Kumwe kutsemuka kungasaonekwe pamusoro uye kunogona kukonzera kushandiswa zvisina kuchengeteka kwebhasikoro rakapwanyika. Unoziva sei kana pakatsemuka mukaticarbon fiber bhasikorokana kuti kwete?

Imwe nzira iri kushandisa state of the art yeX-ray technology - kunyanya X-ray tomography - inozivikanwawo se microCT kana CT scanning.Iyi nzira inoshandisa X-ray kutarisa mukati mezvikamu uye kuona kana paine makatsemuka kana kunyange kugadzira kukanganisa.Ichi chinyorwa chinopfupisa chidzidzo chechiitiko apo CT yakashandiswa kufananidzira makatsemuka mune maviri akaputsikacarbon fiber bikes.

Nzira yekudzivirira sei carbon fiber frame?

Hapana kuratidzwa kwekushisa kwepamusoro

Kunyangwe kabhoni faibha ine tembiricha inopikisa, kuratidzwa kwezuva kwenguva refu kunogona kukonzera kukuvadzwa kwependi yekunze, saka ndapota usafumure bhasikoro kune kunze kwekupisa tembiricha kana kuriisa mukati mekushisa kwepamusoro mukati kana mumotokari.

Kuchenesa nguva dzose

Nguva dzose kucheneswa kwefuremu zvakare mukana wekuongorora bhasikoro.Paunenge uchichenesa furemu, unofanirwa kutarisa kana yakakuvara kana kukweshwa.Usashandise non-professional kemikari zvinonyungudutsa kuchenesa furemu.Inokurudzirwa kushandisa nyanzvi dzekuchenesa mabhasikoro.Usashandisa asidi yakasimba, alkali yakasimba (yakachena, sweat, munyu) uye mamwe makemikari ane kuchenesa masheji kuti uchenese kabhoni fiber motokari kuti urege kukuvadzwa kwepende yemapuranga.
