Chingwe cha mapaipi a silicon carbide: Kodi "zida zosaoneka" za mapaipi a mafakitale zimagwira ntchito bwanji?

Mu mafakitale amakono, njira zoyendetsera mapaipi zili ngati "mitsempha yamagazi" ya thupi la munthu, zomwe zimagwira ntchito yofunika kwambiri yonyamula zinthu zotentha kwambiri komanso zowononga.silicon carbide (SiC) mkati mwakeUkadaulo uli ngati kuyika zida zankhondo zapamwamba pa "mitsempha yamagazi" iyi, zomwe zimapangitsa kuti payipiyo ikhale yolimba, yolimba, komanso yolimba. Kodi gawo lotetezali lomwe limawoneka losavuta limateteza bwanji magwiridwe antchito okhazikika a mapaipi?
1, Katundu wa Zinthu: "Talente yobadwa nayo" ya silicon carbide
Silicon carbide imadziwika kuti "diamondi yakuda yamakampani", ndipo kapangidwe kake ka atomiki ndi kristalo wamtundu wa magawo atatu wopangidwa ndi ma covalent bonds pakati pa silicon ndi kaboni, zomwe zimapatsa zinthu zitatu zofunika:
1. Kulimba kwa diamondi (kwachiwiri pambuyo pa diamondi mu kulimba kwa Mohs), komwe kumatha kupirira kuwonongeka kwa tinthu tating'onoting'ono
2. Kusagwira ntchito kwa mankhwala kwamphamvu kwambiri, kosagonjetsedwa ndi zinthu zowononga monga ma acid, maziko, ndi mchere
3. Kukhazikika kwabwino kwambiri pa kutentha, kusunga bata la kapangidwe kake ngakhale kutentha kwambiri kwa 1350 ℃
Kapangidwe kake ka zinthu kamapangitsa kuti kakhale kotetezeka kwambiri pa ntchito zovuta kwambiri.
2, Njira Yodzitetezera: Dongosolo Lodzitetezera Lachitatu
Pamene chingwe cha silicon carbide chikamamatira kukhoma lamkati la payipi, chimapanga zigawo zingapo zotetezera:
Chotchinga chakuthupi: makhiristo a silicon carbide okhuthala amalekanitsa mwachindunji chotchingacho kuti chisakhudze thupi la chubu chachitsulo
Chigawo chokhazikika cha mankhwala: kupanga filimu yoteteza okosijeni kudzera mu passivation reaction, kukana dzimbiri mwachangu
Njira yotetezerayi imalola mapaipi kusunga mawonekedwe ake ngakhale pansi pa mikhalidwe yovuta monga dzimbiri lamphamvu, kuwonongeka kwambiri, komanso kutentha kwambiri.

3, Chinsinsi cha opaleshoni ya nthawi yayitali: kuthekera kodzichiritsa
Kafukufuku waposachedwapa wapeza kuti silicon carbide ili ndi mphamvu yapadera yogwirizanitsa pamwamba pa zinthu zinazake. Pakachitika kuwonongeka kwa microscopic, maatomu a silicon omwe ali pamwamba pa zinthuzo amakonzedwanso pamalo otentha kwambiri, ndikukonza pang'ono zolakwika pamwamba. Izi zimawonjezera kwambiri moyo wautumiki wa denga ndikuchepetsa kuchuluka kwa kukonza.
4, Ubwino Wosaoneka: Mtengo wathunthu wa moyo
Poyerekeza ndi zipangizo zachikhalidwe zolumikizira, silicon carbide lining imabweretsa phindu lobisika koma lalikulu pazachuma ku mabizinesi amafakitale mwa kuchepetsa kuchuluka kwa kutsekedwa kuti akonze, kuchepetsa chiopsezo cha kuipitsidwa kwapakati, ndikukulitsa nthawi yosinthira mapaipi. Makamaka m'magawo a mankhwala abwino ndi kukonzekera zinthu zatsopano zamagetsi, kufunika kwa chitsimikizo cha kuyera kwa zinthu kumakhala kovuta kwambiri kuyeza ndi deta yosavuta.
Ndi chitukuko cha ukadaulo wa mafakitale kuti ukhale wogwira ntchito bwino komanso wochezeka kwa chilengedwe, ukadaulo wa silicon carbide lining ukusintha kuchoka pa "chitetezo chapadera" kupita ku "makonzedwe wamba". Yankho ili lomwe limaphatikiza sayansi yazinthu ndi luntha la uinjiniya limateteza mwakachetechete "njira yothandiza" yamakampani amakono ndipo limakhala chithandizo chofunikira chaukadaulo pakukweza mtundu ndi magwiridwe antchito amakampani opangira zinthu.
