Ekukhiqizweni kwezimboni zanamuhla, izinhlelo zamapayipi zifana “nemithambo yegazi” yomzimba womuntu, zenza umsebenzi obalulekile wokuthutha izinto ezishisa kakhulu nezingcolisayo.ulwelwesi lwe-silicon carbide (SiC)ubuchwepheshe bufana nokubeka ungqimba lwezivikelo ezisebenza kahle kakhulu kule "mithambo yegazi", okunikeza ipayipi ukumelana okuqinile kokucindezela, ukumelana nokugqwala, kanye nokumelana nokushisa okuphezulu. Lolu ngqimba olubonakala lulula lokuvikela luvikela kanjani ukusebenza okuzinzile kwamapayipi?
1、 Izakhiwo zezinto ezibonakalayo: "Ithalente elingokwemvelo" le-silicon carbide
I-silicon carbide yaziwa ngokuthi “idayimani elimnyama lezimboni”, futhi isakhiwo sayo se-athomu siyikristalu yenethiwekhi enezinhlangothi ezintathu eyakhiwe ngezibopho ze-covalent phakathi kwe-silicon ne-carbon, okuyinika izakhiwo ezintathu ezibalulekile:
1. Ukuqina kwe-diamond grade (okungokwesibili kuphela ngemva kwe-diamond ngokuqina kwe-Mohs), okungamelana nokuguguleka kwezinhlayiya
2. Ukungasebenzi kahle kwamakhemikhali okunamandla kakhulu, okumelana nezinto ezilimazayo ezifana nama-asidi, izisekelo, nosawoti
3. Ukuqina okuhle kakhulu kokushisa, okugcina ukuqina kwesakhiwo ngisho noma amazinga okushisa aphezulu angu-1350 ℃
Le mpahla yezinto ezibonakalayo yenza kube yinto efanelekile yokuvikela izimo zokusebenza ezimbi kakhulu.
2, Indlela Yokuvikela: Uhlelo lokuzivikela oluthathu
Uma ulwelwesi lwe-silicon carbide lunamathela odongeni lwangaphakathi lwepayipi, lwakha izendlalelo eziningi zokuvikela:
Isendlalelo sokuvimbela ngokomzimba: amakristalu e-silicon carbide aminyene ahlukanisa ngqo i-medium ukuthi ingathintani nomzimba weshubhu lensimbi
Isendlalelo esizinzile samakhemikhali: ukwakha ifilimu ye-oxide evikelayo ngokusabela kwe-passivation, ukumelana ngenkuthalo nokugqwala
Le ndlela yokuvikela ehlanganisiwe ivumela amapayipi ukuthi alondoloze ubuqotho besakhiwo ngisho nangaphansi kwezimo ezinzima njengokugqwala okunamandla, ukuguguleka okuphezulu, kanye nezimo zokushisa okuphezulu.
3, Imfihlo yokusebenza isikhathi eside: amandla okuziphilisa
Ucwaningo lwakamuva luthole ukuthi i-silicon carbide inekhono eliyingqayizivele lokuhlanganisa ubuso ngaphansi kwezimo ezithile zokusebenza. Uma kwenzeka umonakalo omncane kakhulu, ama-athomu e-silicon amahhala ebusweni bezinto azohlelwa kabusha endaweni eshisa kakhulu, alungise kancane amaphutha obuso. Lesi sici sandisa kakhulu impilo yenkonzo yolwelwesi futhi sinciphise imvamisa yokugcinwa.
4, Izinzuzo ezingabonakali: inani eliphelele lomjikelezo wokuphila
Uma kuqhathaniswa nezinto zokwemboza zendabuko, ulwelwesi lwe-silicon carbide luletha izinzuzo zomnotho ezifihliwe kodwa ezinkulu emabhizinisini ezimboni ngokunciphisa inani lokuvalwa kokulungiswa, ukunciphisa ingozi yokungcola okuphakathi, kanye nokwandisa umjikelezo wokushintsha ipayipi. Ikakhulukazi emikhakheni yamakhemikhali amahle kanye nokulungiswa kwezinto ezintsha zamandla, inani lokuqinisekiswa kobumsulwa bezinto linzima kakhulu ukulilinganisa ngedatha elula.
Ngokuthuthuka kobuchwepheshe bezimboni kuya ekusebenzeni kahle okukhulu kanye nobungane bemvelo, ubuchwepheshe be-silicon carbide lining bushintsha busuka “ekuvikelweni okukhethekile” kuya “ekulungiselelweni okujwayelekile”. Lesi sixazululo esihlanganisa isayensi yezinto ezibonakalayo kanye nobuhlakani bobunjiniyela sivikela buthule “umzila wokuphila” wemboni yanamuhla futhi siba ukwesekwa okubalulekile kobuchwepheshe ekuthuthukiseni ikhwalithi kanye nokusebenza kahle kwezimboni zezinqubo.
