Kodi njinga zaku China ndizabwino?

Njinga zaku China zili ndi msika waukulu mkati mwa China komanso padziko lonse lapansi.Pali zambiriopanga njinga za carbonku China zomwe zimathandizira msika waukuluwu komanso womwe ukukula nthawi zonse.

Mphamvu zogula za anthu padziko lonse lapansi omwe amakonda Bike zimasiyana.Zimatengeranso chifukwa cha zomwe amakonda.

M’maiko ambiri, monga Netherlands, Germany, Norway, ndi Sweden, anthu amasamala za chilengedwe.Pazachuma zomwe zikukula monga India, Brazil, kapena China pomwe, anthu ambiri amasankha Bike chifukwa chakuti mafuta ndi okwera mtengo kwambiri.

Bike imatha kusintha mizinda yaku China, kuchepetsa kuipitsidwa, kukonza thanzi la anthu mamiliyoni ambiri, ndikupereka chitsanzo kwa apaulendo ndi kugawana makampani kulikonse.njira zanjinga zochokera ku China zomwe zitha kupitilira mliriwu, ndikusintha momwe timayendera zaka zikubwerazi.

Kodi mafelemu onse a njinga za kaboni amapangidwa ku China?

Sikuti mafelemu onse a carbon fiber amapangidwa ku China.

M'kumvetsetsa kwa anthu, zinthu zambiri zimapangidwa ku China, kotero ndikoyenera kunena zimenezo.Zambiri mwazinthu zopangidwa ndi kaboni zomwe zimagulitsidwa panjinga zanjinga zimachokera ku Taiwan kapena ku China.Koma mafelemu ndi magawo ena a carbon fiber amapangidwanso ku United States ndi France.

Ngakhale ulusi wa kaboni umadziwika bwino ngati danga m'masiku oyambilira, ulusi wa kaboni ndioyenera kwambiri pokonza pang'ono.Malo ogulitsira ang'onoang'ono aku America komanso ngakhale ma workshop achinsinsi amatha kukonza kaboni.Ambiri opanga njinga amatha kupanga mafelemu awoawo a njinga kuchokera kunsalu ya carbon fiber, ndipo njira yopangira njingayo siyosiyana ndi ya opanga njinga zazikulu.

Koma carbon yaiwisi imachokera ku China.Mpweya wa carbon umapangidwa ndipolyacrylonitrile (PAN) fiber.Ulusi wa polyacrylonitrile udzatenthedwa kutentha kwambiri, ndipo zinthu zopanda kaboni muzitsulo zidzawotchedwa, ndikusiya ulusi wochepa kwambiri wautali.Akamakonzedwa mokwanira, m'pamenenso zinthuzo zimakhala zolimba kwambiri

Iyi ndi njira yovuta ya mafakitale, ndipo ndi makampani ochepa okha padziko lapansi omwe amatha kupanga zida za carbon fiber.Kupyolera mu lipoti la US Department of Energy la 2010, titha kupeza kuti zoposa 90% za mpweya wa carbon fiber padziko lonse zimachokera ku makampani asanu ndi limodzi okha: Toray, Teijin Group, Mitsubishi Rayon, Zoltek, Hexcel ndi Cytec.Toray, Teijinndipo Mitsubishi idachita pafupifupi magawo awiri mwa atatu a mpweya wopangidwa padziko lonse lapansi.Zoltek, Hexcel ndi Cytec ali ku United States ndipo amatulutsa zosakwana gawo limodzi mwa magawo atatu a carbon fiber output.

Kodi njinga zamapiri ndi Carbon?

Osati zonsenjinga zamapirindi carbon, General ndi zitsulo / aluminium / titaniyamu / carbon.

koma anthu ochulukirachulukira angakonde kugula njinga yamapiri ya carbon frame.Ndiwopepuka, imayamwa bwino, ndipo imatha kupangidwa mosavuta kukhala mawonekedwe aliwonse.

Kwa chimango chachitsulo, ndi chosavuta kuwotcherera, mtengo wotsika, kuyamwa bwino kwamphamvu, mawonekedwe okongola, ndipo nthawi zambiri mawonekedwe apamwamba kwambiri.Koma vuto lalikulu la chitsulo ndilosavuta kuti likhale ndi dzimbiri, choncho kupewa dzimbiri ndi vuto lalikulu, ndipo chimango chachitsulo chimakhala cholemera kwambiri.

Kwa aluminiyumu, kulemera kwake kumakhala kopepuka, kosavuta kusintha, kukonza kumakhala kosavuta, ndipo mtengo wake ndi wotsika mtengo.The kuipa kutentha kutentha chofunika kuonjezera mphamvu, ndi kutopa ntchito ndi osauka.

Kwa Titaniyamu, zabwino zake ndikuti chimango ndi chopepuka, champhamvu, ndipo chimakhala ndi kukwera bwino komanso kukana dzimbiri.Kuipa ndi mtengo ndi okwera mtengo.

Aliyense amakonda zipangizo zosiyanasiyana.Malinga ndi ubwino ndi kuipa kwa zipangizo zosiyanasiyana pamwambapa, ndikofunika kwambiri kugula njinga yomwe mumakonda.

Kodi mafelemu a njinga zamoto za carbon fiber ndi olimba bwanji?

Okwera ambiri amawopa kuwononga mtengo wa carbon frame.Chiyerekezo cha mphamvu ya carbon fiber ndi kulemera kwake ndikwambiri kuposa chitsulo ndipo mafelemu a carbon amatha kupulumuka nkhanza zambiri.Ilinso ndi moyo wotopa kwambiri ndipo, pansi pamikhalidwe yabwino, kugwiritsidwa ntchito kwanthawi yayitali sikungalephereke.Utotowu, komabe, ukhoza kutsika ukakhala ndi kuwala kwa UV, koma ndichifukwa chake mafelemu amapakidwa utoto, ngakhale mafelemu “aawisi” amakhala ndi malaya owoneka bwino okhala ndi zoletsa za UV zomangidwa.Pali china chake chotsamira pamapindikira othamanga kwambiri ndikugwiritsa ntchito mphamvu panjinga ya kaboni yomwe simumapeza ndi aluminiyamu.Ngati mumangofuna kukwera kulikonse kulikonse, Carbon ndi yabwino kwambiri, yowoneka bwino, yachangu, yomvera komanso yowongolera.Zili ngati kukhala ndi BMW.Zosalala, zabwino… mwachangu!

Njinga za mapiri a carbon ndi zolimba kwambiri.Kulemera kwa mphamvu ndi 18 peresenti kuposa aluminium.Mafelemu a njinga zamapiri apamwamba amatha kufika ku 700 KSI (kilopounds per square inchi) asanadutse.Pamene njinga yamoto ya carbon phiri ikuphwanyidwa, simapindika kapena kupukuta, m'malo mwake, imasweka.Kuwonongeka kumeneku kungakhale kosaoneka kapena kuoneka.Ndipo mwina ndichifukwa chake zapeza rap yoyipa mu dipatimenti yokhazikika.Chikhulupiriro cha kompositi chikasokonekera, chimakhala chofooka kwambiri ndipo chowopsa kupitiliza kugwiritsa ntchito.Momwemo, iyenera kukonzedwa kapena kusinthidwa. Monganso zida zina, mpweya umawonongeka ndi kugwiritsidwa ntchito, pakapita nthawi yayitali.Mpweya uli ndi kutopa kwa chimango kwautali kwambiri komwe kumathandizira opanga ambiri kuti apereke chitsimikizo cha moyo wawo wonse pamafelemu opangidwa ndi zinthuzi.Ukalamba ukayamba, utomoni umakhala ukupanga ming'alu yaying'ono, ndipo zomwe zatsala ndi kulumikizana kwa ulusi.Kuuma kwa chimango chanjinga kudzasintha pang'ono panjira.

momwe mungadulire njinga yamoto ya carbon fiber?

Kuti mupange kaboni, gwiritsani ntchito hacksaw yokhala ndi tsamba la tungsten carbide.Ikani masking tepi pamwamba pa odulidwa ndikulemba chizindikiro pamwamba pa masking tepi.Izi zidzateteza mpweya kuti usawonongeke.Ikani zogwirira ntchito poyimilira njinga ndikuchepetsani kuti zifanane ndi pansi.

Posankha m'lifupi mwa chogwirizira chatsopano, khalani osamala.Nthawi zonse ndizotheka kuchotsa zambiri pambuyo pake.Onetsetsaninso kuti muchepetse m'lifupi mofanana - mukafupikitsa mipiringidzo ndi 40mm yonse, dulani 20mm mbali iliyonse.

Pali njira zingapo zomwe zingagwiritsidwe ntchito kudziwa kukula kwa mipiringidzo - nazi zingapo zomwe timakonda: Khalani panjinga.Tsekani maso anu (onetsetsani kuti njingayo ndi yokhazikika), fikirani ndikugwira zogwirira ntchito pamalo omwe akumva bwino.Tengani muyeso wa kutalika kwa chogwiracho kuyambira pakunja kwa dzanja lanu.Chotsani osachepera 10 mm kuchokera pa nambala iyi kuti mudzipatse malire owonjezera - kachiwiri, khalani osamala.Nambala iyi ndi ndalama zomwe mudzachotse kumapeto kulikonse kwa chogwirizira.

Njira iyi idzafuna thandizo lothandizira.Konzekerani kukankhira mmwamba, manja anu ali pansi pamapewa-m'lifupi mwake.Pemphani wina kuti ayeze momwe manja anu alili, kuchokera kunja kwa dzanja limodzi kupita ku linalo.Apanso, onjezani 20 mm pamphepete mwabwino, ndipo muli ndi m'lifupi mwake mwazogwirizira zanu.
