Zipangizo zodziwika bwino za kutentha: Zipangizo zophatikizika za C/C

Zosakaniza za kaboni ndi kabonindi mtundu wa zinthu zopangidwa ndi ulusi wa kaboni, zokhala ndi ulusi wa kaboni ngati chinthu cholimbikitsira ndi kaboni wosungidwa ngati chinthu cha matrix.Zosakaniza za C/C ndi kaboniPopeza pafupifupi yonse ili ndi kaboni woyambira, imakhala ndi kukana kutentha kwambiri ndipo imalandira mphamvu zamphamvu za ulusi wa kaboni. Yakhala ikugwiritsidwa ntchito m'mafakitale m'munda wachitetezo kale.

Madera ogwiritsira ntchito:

Zipangizo zophatikizika za C/Cali pakati pa unyolo wa mafakitale, ndipo pamwamba pake pali ulusi wa kaboni ndi kupanga zinthu za preform, ndipo minda yogwiritsira ntchito pansi pake ndi yayikulu.Zipangizo zophatikizika za C/CAmagwiritsidwa ntchito makamaka ngati zipangizo zosatentha, zipangizo zokangana, komanso zipangizo zogwirira ntchito bwino kwambiri. Amagwiritsidwa ntchito mumlengalenga (zophimba pakhosi pa rocket nozzle, zipangizo zoteteza kutentha ndi zida zomangira kutentha kwa injini), zipangizo zomangira ma brake (njanji yothamanga kwambiri, ma disc a ma brake a ndege), malo otentha a photovoltaic (migolo yoteteza kutentha, zophimba, machubu otsogolera ndi zina), matupi amoyo (mafupa opangidwa) ndi malo ena. Pakadali pano, malo ogwirira ntchito m'nyumbaZipangizo zophatikizika za C/CMakampani makamaka amayang'ana kwambiri ulalo umodzi wa zinthu zophatikizika ndipo amafikira ku njira yopita patsogolo.

Zipangizo zophatikizika za C/C zimakhala ndi magwiridwe antchito abwino kwambiri, zokhala ndi kachulukidwe kochepa, mphamvu yayikulu, modulus yayikulu, kutentha kwakukulu, kukulitsa kutentha kochepa, kulimba bwino kwa kusweka, kukana kuwonongeka, kukana kusweka, ndi zina zotero. Makamaka, mosiyana ndi zipangizo zina, mphamvu ya zipangizo zophatikizika za C/C sizingachepe koma zitha kuwonjezeka ndi kutentha. Ndi chinthu chabwino kwambiri cholimbana ndi kutentha, chifukwa chake chakhala chikupangidwa koyamba m'mafakitale a rocket throat liners.

Zipangizo zopangidwa ndi C/C zimalandira mphamvu zabwino kwambiri zamakina ndi mphamvu zokonzera za ulusi wa kaboni, ndipo zimakhala ndi kukana kutentha ndi dzimbiri kwa graphite, ndipo zakhala mpikisano wamphamvu wa zinthu zopangidwa ndi graphite. Makamaka m'munda wogwiritsira ntchito womwe umafunika mphamvu zambiri - mphamvu ya photovoltaic thermal field, kugwiritsa ntchito bwino ndalama komanso chitetezo cha zipangizo zopangidwa ndi C/C zikukhala zodziwika kwambiri pansi pa mawafer akuluakulu a silicon, ndipo zakhala zofunikira kwambiri. M'malo mwake, graphite yakhala yowonjezera ku zipangizo zopangidwa ndi C/C chifukwa cha kuchepa kwa mphamvu zopangira kumbali yoperekera.

Kugwiritsa ntchito mphamvu ya dzuwa pa malo otentha:

Munda wotentha ndi dongosolo lonse losungira kukula kwa silicon ya monocrystalline kapena kupanga ma ingot a silicon a polycrystalline pa kutentha kwina. Umagwira ntchito yofunika kwambiri pa kuyera, kufanana ndi makhalidwe ena a silicon ya monocrystalline ndi silicon ya polycrystalline, ndipo uli m'gulu la makampani opanga ma silicon a crystalline. Munda wotentha ukhoza kugawidwa m'magulu awiri: makina otenthetsera a monocrystalline silicon single crystal pulling furnace ndi makina otenthetsera a polycrystalline ingot furnace malinga ndi mtundu wa chinthucho. Popeza maselo a silicon a monocrystalline ali ndi mphamvu yosinthira kwambiri kuposa maselo a silicon a polycrystalline, gawo la msika wa ma wafers a silicon a monocrystalline likupitirirabe kukwera, pomwe gawo la msika wa ma wafers a silicon a polycrystalline m'dziko langa lakhala likuchepa chaka ndi chaka, kuyambira 32.5% mu 2019 mpaka 9.3% mu 2020. Chifukwa chake, opanga ma thermal field amagwiritsa ntchito kwambiri njira yaukadaulo wa thermal field ya ma thermal crystal pulling furnace.

Chithunzi 2: Malo otentha mu unyolo wa makampani opanga zinthu za silicon

Munda wotentha umapangidwa ndi zigawo zoposa khumi ndi ziwiri, ndipo zigawo zinayi zazikulu ndi chovindikira, chubu chotsogolera, silinda yoteteza kutentha, ndi chotenthetsera. Zigawo zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana pazinthu zakuthupi. Chithunzi chomwe chili pansipa ndi chithunzi cha munda wotentha wa silikoni imodzi ya kristalo. Chovindikira, chubu chotsogolera, ndi silinda yoteteza kutentha ndi zigawo za kapangidwe ka dongosolo la munda wotentha. Ntchito yawo yayikulu ndikuchirikiza munda wonse wotentha wotentha kwambiri, ndipo ali ndi zofunikira kwambiri pakuchulukana, mphamvu, ndi kuyendetsa kutentha. Chotenthetsera ndi chinthu chotenthetsera mwachindunji mu munda wotentha. Ntchito yake ndikupereka mphamvu yotentha. Nthawi zambiri chimakhala chotsutsa, kotero chimakhala ndi zofunikira kwambiri pakutsutsa zinthu.
