Ishubhu yokuvikela ye-silicon carbide

Ezimbonini lapho izimo ezimbi kakhulu zisongela khona ubuqotho bemishini,amashubhu okuvikela e-silicon carbide (SiC)kuvela njengesixazululo esiyingqayizivele. Ngokungafani nezinto zokuvikela ezivamile, amashubhu e-SiC ahlanganisa isayensi yezinto ezithuthukisiwe nobunjiniyela obuqinile ukuvikela amathuluzi nezinqubo ezibalulekile. Inezinzuzo ezilandelayo:

1. Ukuvikelwa Okungalingani Ezimweni Ezinobutha

Amashubhu okuvikela e-SiC asebenza njengomugqa wokuqala wokuzivikela ezindaweni lapho ukwehluleka kungeyona inketho:

（1）Ukuzivikela Kokushisa: Imelana namazinga okushisa ahlala isikhathi eside afinyelela ku-1600°C, izinzwa zokuvikela, ama-thermocouple, noma ama-probe avela ezinsimbini ezincibilikisiwe, amalangabi, kanye ne-plasma.

（2）Ukungavikeleki Kwamakhemikhali: Ukumelana nokugqwala okuvela kuma-asidi (isb. i-sulfuric, i-hydrochloric), ama-alkali, namagesi asabelayo njenge-chlorine noma i-sulfur oxides.

Ukumelana Nokuguguleka: Vikela ezinhlayiyeni ezigugulekayo emibhedeni emanzi, kuma-gasifier amalahle, noma emisebenzini yokumba.

2. Ukunemba Nokuzinza Kwezilinganiso Ezibucayi

Ezinqubweni zezimboni ezisengozini enkulu, ukunemba kubaluleke kakhulu. Amashubhu e-SiC athuthukisa ukuthembeka ngokuthi:

（1）Ukunciphisa Ukuphazamiseka Kwesignali: Izakhiwo ezingahambisani nogesi zivimbela ukuphazamiseka kwe-electromagnetic kuma-sensor kagesi.

（2）Ukuzinza Kokushisa: Ukuguquguquka kokushisa okucishe kube yi-zero kuqinisekisa ukuhambisana okuhambisanayo kanye nokunemba kokulinganisa ngaphansi kokushintshashintsha kwezinga lokushisa okusheshayo.

（3）Ubuqotho Obuqinile Ngegesi: Isakhiwo esingangenisi amanzi sivimbela ukungena kwegesi, okubalulekile ezinhlelweni ze-vacuum noma ezindaweni ezilawulwayo.

3. Ukunika amandla ubuchwepheshe besizukulwane esilandelayo amashubhu okuvikela e-SiC avula izinto ezintsha emikhakheni ekhulayo:

（1）Umnotho we-Hydrogen: Usebenza njengezivikelo eziqinile zezinzwa ekukhiqizweni kwe-hydrogen, isitoreji, kanye namaseli kaphethiloli, okumelana nokuqhekeka kanye nokuvezwa kwe-H₂ enomfutho ophezulu.

（2）Ukukhiqizwa kwe-Semiconductor: Vikela izinzwa zokukhanya nezokushisa kuma-reactor e-CVD (Chemical Vapor Deposition) kuma-precursors abhubhisayo njenge-silane noma i-ammonia.

（3）Ukuhlola Isikhala: Ukuvikela izinsimbi ezinjinini zamarokhethi kanye nama-probe eplanethi kusuka kuma-gradient ashisayo kakhulu kanye nemisebe ye-cosmic.

4. Ukonga Izindleko Ngokusebenzisa Isikhathi Eside

Nakuba amashubhu e-SiC enezindleko eziphezulu kusengaphambili, izinzuzo zomjikelezo wawo wokuphila zichaza kabusha inani:

（1）Isikhathi Sokungasebenzi Esincishisiwe: Izindlela zokukhipha insimbi noma i-quartz ngo-4–6x ezindaweni ezirhabaxa noma ezine-asidi, okunciphisa ukulungiswa okungahleliwe.

（2）Izidingo Zokumboza Okungavimbeli: Ngokungafani nezinsimbi ezidinga ukumbozwa okuvikelayo, izakhiwo ze-SiC ezingokwemvelo zisusa izindleko zokwelashwa kwendawo eziphindaphindayo.

（3）Ukusetshenziswa Kabusha: Kusinda emijikelezweni eminingi yenqubo kuzinhlelo zokusebenza ezifana nokusatshalaliswa kwensimbi noma ukwakheka kwengilazi ngaphandle kokuwohloka.

5. Ukwenza ngokwezifiso izidingo ezikhethekile

Amashubhu okuvikela e-SiC avumelana nezinselele ze-niche ngobunjiniyela obulungiselelwe wena:

（1）Imiklamo ye-Hybrid: Hlanganisa nezinsimbi noma izinto zobumba ukuze kuhlanganiswe izinto eziningi (isib. izixhumi ezinezintambo, ama-flange).

（2）Ukuguqulwa Kobuso: Ingaphakathi elicwebezelisiwe lezinhlelo zokusebenza zokukhanya noma ingaphandle elinobunjwa ukuze kuthuthukiswe ukushabalaliswa kokushisa.

（3）Usayizi Ukuguquguquka: Kwenziwe ngamamilimitha (ama-reactor esikalini selabhorethri) kuya kumamitha (ama-kiln ezimboni).

6. Ukuqondanisa Ukuzinza

Amashubhu e-SiC asekela imikhuba yezimboni enobungani nemvelo:

（1）Ukonga Amandla: Ukusebenza kahle kokushisa kunciphisa ukusetshenziswa kukaphethiloli wesithando ngo-20% uma kuqhathaniswa nezihlangu zensimbi.

（2）Ukunciphisa Udoti: Ukuphila isikhathi eside kwenkonzo kunciphisa udoti wezinto ezibonakalayo ngenxa yokushintsha njalo.

（3）Ukunciphisa Ubuthi: Susa isidingo sezingubo eziyingozi (isb., ama-alloy asekelwe ku-nickel) ezindaweni ezigqwalisayo.

I-Shandong Zhongpeng Special Ceramics Co., Ltd ingenye yezixazululo ezinkulu zezinto ezintsha ze-silicon carbide ceramic eShayina. I-SiC technical ceramic: Ubulukhuni bukaMoh buyi-9 (ubulukhuni bukaMoh obuyi-13), bunokumelana okuhle kakhulu nokuguguleka nokugqwala, ukumelana okuhle kakhulu - ukumelana nokugqwala kanye nokulwa nokubola. Impilo yesevisi yomkhiqizo we-SiC ide ngokuphindwe ka-4 kuya ku-5 kune-92% ye-alumina material. I-MOR ye-RBSiC iphindwe ka-5 kuya ku-7 kune-SNBSC, ingasetshenziswa ezimweni eziyinkimbinkimbi kakhulu. Inqubo yokucaphuna iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ayilingani. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisela izinhliziyo zethu emphakathini.
