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 aC/C composites ndi carbon. 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 zodzitchinjiriza ndi zida zama injini zamatenthedwe), zida zama brake (njanji yothamanga kwambiri, ma brake discs oyendetsa ndege), malo otentha a photovoltaic (migolo ya insulation, crucibles, machubu owongolera ndi zinthu zina), matupi achilengedwe (mafupa opangira) ndi magawo ena. 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, ma module apamwamba kwambiri, matenthedwe apamwamba kwambiri, kuchuluka kwamafuta ochepa, kulimba kwabwino kwa fracture, kukana kuvala, kukana kutulutsa, etc. Makamaka, mosiyana ndi zida zina, mphamvu ya C / C zida zophatikizika sizingachepe koma zitha kuchulukira ndikuwonjezera 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.

Photovoltaic thermal field application:

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 mphamvu zosinthika kwambiri kuposa ma cell a silicon a polycrystalline, gawo la msika la zowotcha za silicon za monocrystalline likupitilira kukula, pomwe gawo lamsika la zowotcha za polycrystalline silicon mdziko langa lakhala likuchepera chaka ndi chaka, kuchoka pa 32.5% mu 2019 mpaka 9.3% mu 2020. Choncho, opanga matenthedwe am'munda makamaka amagwiritsa ntchito njira yaukadaulo yotenthetsera imodzi yokoka kristalo. 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.
