Zida zopangira mafuta ambiri: C / C zophatikizika

Mpweya wa carbon-carbonndi mtundu wa carbon fiber composites, ndi mpweya CHIKWANGWANI monga reinforcement chuma ndi waikamo mpweya monga matrix zinthu. Matrix aZophatikiza za C / C ndi kaboni. Popeza imakhala yopangidwa ndi elemental carbon, imakhala ndi kukana kutentha kwambiri ndipo imatenga mphamvu zamakina a carbon fiber. Zakhala zikuchulukirachulukira m'munda wachitetezo kale.

Malo ofunsira:

C / C zida zophatikizikazili pakati pa unyolo wa mafakitale, ndipo kumtunda kumaphatikizapo mpweya wa carbon fiber ndi preform kupanga, ndi minda yogwiritsira ntchito kunsi kwa mtsinje ndi yotakata.C / C zida zophatikizikaamagwiritsidwa ntchito makamaka ngati zida zosagwira kutentha, zida zolimbana, komanso zida zamakina apamwamba kwambiri. Amagwiritsidwa ntchito muzamlengalenga (zovala zapakhosi za roketi, zida zoteteza kutentha ndi zida zamakina a injini), zida zoboola (njanji yothamanga kwambiri, ma brake discs oyendetsa ndege), malo otentha a Photovoltaic (migolo ya insulation, crucibles, machubu owongolera ndi zigawo zina), matupi achilengedwe (mafupa opangira) ndi zina. Pakali pano, m'nyumbaC / C zida zophatikizikaMakampani amayang'ana kwambiri ulalo umodzi wazinthu zophatikizika ndikufikira kumayendedwe akumtunda.

Zida zophatikizika za C / C zimakhala ndi magwiridwe antchito abwino kwambiri, okhala ndi kachulukidwe kakang'ono, mphamvu zenizeni zenizeni, modulus yapamwamba kwambiri, kukhathamiritsa kwamafuta otsika, kuchuluka kwamafuta otsika, kulimba kwapang'onopang'ono, kukana kuvala, kukana kwa ablation, etc. Makamaka, mosiyana ndi zida zina, mphamvu ya C / C yophatikizika sizingachepe koma zitha kuchulukirachulukira pakuwonjezeka kwa kutentha. Ndi chinthu chabwino kwambiri chosamva kutentha, chifukwa chake idapangidwa koyamba kukhala opanga ma rocket pakhosi.

C / C gulu zinthu cholowa kwambiri mawotchi katundu ndi katundu processing wa mpweya CHIKWANGWANI, ndipo ali ndi kukana kutentha ndi dzimbiri kukana graphite, ndipo wakhala mpikisano wamphamvu graphite mankhwala. Makamaka m'munda wogwiritsira ntchito ndi zofunikira zamphamvu kwambiri - photovoltaic thermal field, kukwera mtengo ndi chitetezo cha C / C zophatikizika zipangizo zikuchulukirachulukira kwambiri pansi pa zowotcha zazikulu za silicon, ndipo zakhala zofunikira kwambiri. M'malo mwake, graphite yakhala chowonjezera ku C / C zida zophatikizika chifukwa cha mphamvu zochepa zopangira mbali yoperekera.

Ntchito yotentha ya Photovoltaic:

Malo otentha ndi dongosolo lonse losungira kukula kwa silicon ya monocrystalline kapena kupanga ma ingots a polycrystalline silicon pa kutentha kwina. Imakhala ndi gawo lalikulu pakuyera, kufanana ndi mikhalidwe ina ya silicon ya monocrystalline ndi silicon ya polycrystalline, ndipo ili kumapeto kwa mafakitale opanga ma crystalline silicon. Munda wotentha ukhoza kugawidwa mu ng'anjo yamoto yotentha ya monocrystalline silicon single crystal kukoka ng'anjo ndi malo otentha a ng'anjo ya polycrystalline ingot malinga ndi mtundu wa mankhwala. Popeza ma cell a monocrystalline silicon ali ndi kutembenuka kwakukulu kuposa ma cell a silicon a polycrystalline, gawo la msika la zowotcha za silicon za monocrystalline likupitilira kukula, pomwe gawo la msika la zowotcha za polycrystalline silicon m'dziko langa lakhala likuchepera chaka ndi chaka, kuchokera ku 32.5% mu 2019 mpaka 9.3% mu 2020. ng'anjo.

Chithunzi 2: Munda wotentha mumndandanda wamakampani opanga ma crystalline silicon

Malo otentha amapangidwa ndi zinthu zopitilira khumi ndi ziwiri, ndipo zigawo zinayi zazikuluzikulu ndi crucible, chubu chowongolera, silinda ya insulation, ndi chotenthetsera. Zigawo zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana za zinthu zakuthupi. Chithunzi chomwe chili pansipa ndi chithunzi chojambula cha malo otentha a silicon imodzi ya crystal. The crucible, chubu chowongolera, ndi silinda yotsekera ndizomwe zimapangidwira gawo la gawo lamatenthedwe. Ntchito yawo yayikulu ndikuthandizira gawo lonse lotentha kwambiri, ndipo ali ndi zofunika kwambiri pakuchulukira, mphamvu, ndi kuwongolera kwamafuta. Chotenthetsera ndi chinthu chowotchera mwachindunji m'munda wotentha. Ntchito yake ndi kupereka mphamvu zotentha. Nthawi zambiri imakhala yosasunthika, chifukwa chake imakhala ndi zofunikira zapamwamba pakulimbana ndi zinthu.
