Emkhiqizweni wesimanje wezimboni, izinhlelo zamapayipi zifana “nemithambo yegazi” yomzimba womuntu, enza umsebenzi obalulekile wokuthutha imithombo yezindaba eshisa kakhulu futhi eyonakalisayo. Ii-silicon carbide (SiC) ulayiniubuchwepheshe bufana nokubeka ungqimba lwezikhali ezisebenza kahle kule “mithambo yegazi”, okunikeza ipayipi eliqinile elicindezelayo, elimelana nokugqwala, kanye nokumelana nezinga lokushisa eliphezulu. Lesi sendlalelo sokuvikela esibonakala silula sikuvikela kanjani ukusebenza okuzinzile kwamapayipi?
1, Izinto ezibonakalayo: "Ithalenta elizalwa" le-silicon carbide
I-Silicon carbide yaziwa ngokuthi "idayimane elimnyama lezimboni", futhi ukwakheka kwayo kwe-athomu kuyikristalu yenethiwekhi enezinhlangothi ezintathu ezakhiwe ngamabhondi aqinile phakathi kwe-silicon ne-carbon, eyinikeza izici ezintathu ezibalulekile:
1. Ukuqina kwebanga ledayimane (okungokwesibili kuphela kwedayimane ngobulukhuni be-Mohs), okungamelana nokuguguleka kwezinhlayiyana
2. Ukungangeni kwamakhemikhali aqine kakhulu, amelana nemithombo yezindaba ebolayo njengama-asidi, izisekelo, nosawoti
3. Ukuzinza okuhle kakhulu kwe-thermal, ukugcina ukuzinza kwesakhiwo ngisho namazinga okushisa aphezulu angu-1350 ℃
Lesi sakhiwo esibonakalayo sikwenza kube yinto ekahle yokuvikela izimo zokusebenza ezidlulele.
2. Indlela yokuvikela: Uhlelo lokuvikela olukathathu
Lapho ulwelwesi lwe-silicon carbide lunamathela odongeni lwangaphakathi lwepayipi, lwakha izendlalelo eziningi zokuvikela:
Isendlalelo sesithiyo esingokomzimba: amakristalu aminyene e-silicon carbide ahlukanisa ngokuqondile okuphakathi ekuxhumaneni nomzimba weshubhu lensimbi.
Isendlalelo esizinzile samakhemikhali: ukwakha ifilimu ye-oxide evikelayo ngokusabela kokudlula, ukumelana nokugqwala.
Le ndlela yokuvikela eyinhlanganisela ivumela amapayipi ukuthi agcine ubuqotho besakhiwo ngisho nangaphansi kwezimo ezinzima njengokugqwala okuqinile, ukuguga okuphezulu, nezimo zokushisa eziphezulu.
3, Imfihlo yokusebenza kwesikhathi eside: amandla okuziphilisa
Ucwaningo lwakamuva luthole ukuthi i-silicon carbide inekhono eliyingqayizivele lokuhlanganisa indawo ngaphansi kwezimo ezithile zokusebenza. Uma kwenzeka umonakalo omkhulu, ama-athomu e-silicon amahhala endaweni ebonakalayo azophinde ahleleke endaweni enezinga lokushisa eliphezulu, alungise ingxenye engalungile yendawo. Lesi sici sinweba kakhulu impilo yesevisi yolayini futhi sinciphisa imvamisa yokulungisa.
4. Izinzuzo ezingabonakali: inani eliphelele lomjikelezo wempilo
Uma kuqhathaniswa nezinto zokwenziwa kolwelwesi ezivamile, ujenga lwe-silicon carbide iletha izinzuzo zezomnotho ezifihlekile kodwa ezinkulu emabhizinisini ezimboni ngokunciphisa inani lokuvalwa kokulungiswa, ukwehlisa ubungozi bokungcoliswa okuphakathi, nokwelula umjikelezo wokushintsha amapayipi. Ikakhulukazi emkhakheni wamakhemikhali amahle kanye nokulungiswa kwezinto zamandla amasha, inani lokuqinisekiswa kokuhlanzeka kwempahla linzima nakakhulu ukulikala ngedatha elula.
Ngokuthuthukiswa kobuchwepheshe bezimboni maqondana nokusebenza kahle okukhulu kanye nobungane bemvelo, ubuchwepheshe be-silicon carbide lining buyashintsha busuka “ekuvikelekeni okukhethekile” buya “ekucushweni okujwayelekile”. Lesi sixazululo esihlanganisa isayensi yezinto ezibonakalayo kanye nobuhlakani bonjiniyela sivikela buthule "indlela yokuphila" yemboni yesimanje futhi siba usekelo olubalulekile lwezobuchwepheshe lokuthuthukisa ikhwalithi nokusebenza kahle kwezimboni zezinqubo.
