Mzere wa mapaipi a Silicon carbide: Kodi "zida zosawoneka" zamapaipi a mafakitale zimagwira ntchito bwanji?

M'mafakitale amakono, machitidwe a mapaipi ali ngati "mitsempha yamagazi" ya thupi la munthu, yomwe ikugwira ntchito yofunika kwambiri yonyamula zinthu zotentha kwambiri komanso zowonongeka. Thesilicon carbide (SiC) liningukadaulo uli ngati kuyika zida zogwira ntchito kwambiri pa "mitsempha yamagazi" iyi, zomwe zimapatsa mapaipi amphamvu kwambiri, osachita dzimbiri, komanso osatentha kwambiri. Kodi chitetezero chooneka ngati chosavutachi chimateteza bwanji ntchito yokhazikika ya mapaipi?
1, Zinthu Zakuthupi: "talente yobadwa nayo" ya silicon carbide
Silicon carbide imadziwika kuti "diamondi yakuda yamafakitale", ndipo mawonekedwe ake a atomiki ndi makristalo amitundu itatu omwe amapangidwa ndi zomangira zolumikizana pakati pa silicon ndi kaboni, ndikuzipatsa zinthu zitatu zofunika:
1. Kulimba kwa kalasi ya diamondi (yachiwiri kwa diamondi mu kuuma kwa Mohs), yomwe ingakane kukokoloka kwa tinthu
2. Kusakhazikika kwamphamvu kwamankhwala, kusagwirizana ndi zowononga zowononga monga ma acid, maziko, ndi mchere.
3. Kukhazikika kwabwino kwamatenthedwe, kusunga bata pamapangidwe ngakhale kutentha kwambiri kwa 1350 ℃
Katundu wazinthu izi zimapangitsa kukhala chinthu choyenera choteteza kuzinthu zogwira ntchito kwambiri.
2. Njira yachitetezo: Chitetezo cha katatu
Mzere wa silicon carbide ukamamatira ku khoma lamkati la payipi, umapanga zigawo zingapo zachitetezo:
Chotchinga chotchinga chakuthupi: makhiristo wandiweyani a silicon carbide amapatula mwachindunji sing'anga kuti isakhudzidwe ndi thupi lachitsulo.
Chemical khola wosanjikiza: kupanga zoteteza oxide filimu kudzera passivation anachita, mwakhama kukana dzimbiri.
Njira yodzitetezera yophatikizika iyi imalola mapaipi kukhalabe osakhulupirika ngakhale pamavuto monga dzimbiri lamphamvu, kuvala kwambiri, komanso kutentha kwambiri.

3, Chinsinsi cha ntchito yayitali: kuthekera kodzichiritsa
Kafukufuku waposachedwa wapeza kuti silicon carbide ili ndi kuthekera kwapadera kophatikizananso pansi pamikhalidwe inayake yogwirira ntchito. Kuwonongeka kwapang'onopang'ono kukuchitika, maatomu a silicon aulere pamtunda amasinthidwanso pamalo otentha kwambiri, kukonza pang'ono zolakwika zapamtunda. Mbali imeneyi imakulitsa kwambiri moyo wautumiki wa chinsalu ndikuchepetsa kukonzanso pafupipafupi.
4, Zopindulitsa zosawoneka: mtengo wamoyo wonse
Poyerekeza ndi zida zachikhalidwe, silicon carbide lining imabweretsa zobisika koma zopindulitsa kwambiri zachuma kumabizinesi akumafakitale pochepetsa kuchuluka kwa kuzimitsidwa pakukonza, kutsitsa chiwopsezo cha kuipitsidwa kwapakati, komanso kukulitsa njira yosinthira mapaipi. Makamaka pazamankhwala abwino komanso kukonzekera kwazinthu zatsopano, kufunikira kwa chitsimikizo cha chiyero chakuthupi kumakhala kovuta kwambiri kuyeza ndi data yosavuta.
Ndi chitukuko chaukadaulo wamafakitale kuti ukhale wothandiza kwambiri komanso wokonda zachilengedwe, ukadaulo wa silicon carbide lining ukusintha kuchokera ku "chitetezo chapadera" kupita ku "kusintha kokhazikika". Yankho ili lomwe limaphatikiza nzeru zakuthupi ndi uinjiniya limateteza mwakachetechete "njira yopezera moyo" yamakampani amakono ndipo imakhala chithandizo chofunikira chaukadaulo pakuwongolera magwiridwe antchito ndi magwiridwe antchito.
