I-silicon carbide protective tube
Ezimbonini lapho izimo ezimbi kakhulu zisongela ubuqotho bemishini,i-silicon carbide (SiC) amashubhu okuvikelakuvela njengesixazululo esiyisisekelo. Ngokungafani nezinto ezivamile zokuvikela, amashubhu e-SiC ahlanganisa isayensi yezinto ezithuthukisiwe nobunjiniyela obuqinile ukuze kuvikelwe amathuluzi nezinqubo ezibalulekile. Inezinzuzo ezilandelayo:
1. Ukuvikelwa Okungenakuqhathaniswa Ezimeni Ezinobutha
Amashubhu okuvikela e-SiC asebenza njengomugqa wokuqala wokuzivikela ezindaweni lapho ukwehluleka kungeyona inketho:
(1) Ukuvikela okushisayo: Ukumelana namazinga okushisa aqhubekayo afika ku-1600°C, izinzwa ezivikelayo, ama-thermocouples, noma ama-probe asuka ezinsimbi ezincibilikisiwe, amalangabi, ne-plasma.
(2) Ukungavikeleki Kwamakhemikhali: Melana nokugqwala okuvela kuma-asidi (isb. isibabule, i-hydrochloric), ama-alkali, namagesi asebenzayo njenge-chlorine noma ama-sulphur oxides.
Ukumelana Nemihuzuko: Vikela ezinhlayiyeni ezigugulekayo emibhedeni enamanzi, izishibhisi zamalahle, noma imisebenzi yezimayini.
2. Ukunemba kanye Nokuqina Kwezilinganiso Ezibalulekile
Ezinqubweni eziphakeme zezimboni, ukunemba kubaluleke kakhulu. Amashubhu e-SiC athuthukisa ukwethembeka ngokuthi:
(1) Ukunciphisa Ukuphazamiseka Kwesiginali: Izakhiwo ezingaqhubeki zivimba ukuphazamiseka kukazibuthe kuzinzwa zikagesi.
(2) Ukuzinza Kokushisa: Ukuguqulwa kwe-thermal eduze neqanda kuqinisekisa ukuqondanisa okungaguquki nokunemba kwesilinganiso ngaphansi kokushintshashintsha kwezinga lokushisa okusheshayo.
(3) Ubuqotho Bokuqina Kwegesi: Isakhiwo esingangenisi sivimbela ukungena kwegesi, okubalulekile kumasistimu we-vacuum noma umkhathi olawulwayo.
3. Ukunika amandla amashubhu okuvikela e-Next-Generation Technologies SiC avula izinto ezintsha ezinkundleni ezisafufusa:
(1) Umnotho We-Hydrojeni: Khonza njengamashethi ahlala isikhathi eside ezinzwa ekukhiqizeni i-hydrogen, isitoreji, namaseli kaphethiloli, amelana ne-embrittlement kanye nokuchayeka kwe-H₂ enengcindezi ephezulu.
(2) Ukukhiqiza I-Semiconductor: Vikela izinzwa ezibonakalayo nezishisayo ku-CVD (Chemical Vapor Deposition) kuma-precursors abolayo njenge-silane noma i-ammonia.
(3) Ukuhlola Umkhathi: Izinsimbi zesivikelo ezinjinini zamarokhethi namaplanethi okuhlola amaplanethi asuka kumazinga ashisayo adlulele kanye nemisebe ye-cosmic.
4. Ukusebenza Kahle Kwezindleko Ngokuphila Kade
Ngenkathi amashubhu e-SiC enezindleko eziphezulu zangaphambili, izinzuzo zomjikelezo wokuphila zichaza kabusha inani:
(1) Isikhathi Sokuphumula Esincishisiwe: Okunye okuhlukile kwensimbi noma i-quartz ngo-4–6x kumasethingi abrasive noma ane-acidic, ukunciphisa ukunakekelwa okungahleliwe.
(2) Izidingo Zokumboza Uziro: Ngokungafani nezinsimbi ezidinga izimbotshana zokuvikela, izakhiwo ezingokwemvelo ze-SiC zisusa izindleko zokwelashwa eziphindelelayo.
(3) Ukusebenziseka kabusha: Sinda emijikelezweni yezinqubo eziningi ezinhlelweni ezifana nokusakazwa kwensimbi noma ukwakheka kwengilazi ngaphandle kokuwohloka.
5. Ukwenza ngokwezifiso Izidingo Ezikhethekile
Amashubhu okuvikela e-SiC azivumelanisa nezinselelo ze-niche ngokusebenzisa ubunjiniyela obulungiselelwe:
(1) Imiklamo yeHybrid: Hlanganisa nezinsimbi noma izitsha zobumba zokuhlanganisa imisebenzi eminingi (isb. izixhumi ezinentambo, ama-flange).
(2) Ukulungiswa komphezulu: Ingaphakathi elipholishiwe lezinhlelo zokusebenza ezibonakalayo noma ingaphandle elithungwe ukuze kuthuthukiswe ukunqamuka kokushisa.
(3) Usayizi Ukuvumelana nezimo: Kwenziwe kusuka kumamilimitha (ama-lab-scale reactor) kuya kumamitha (izihiani zezimboni).
6. Ukuqondanisa Ukusimama
Amashubhu e-SiC asekela imikhuba yezimboni eco-friendly:
(1) Ukonga Amandla: Ukusebenza kahle kokushisa okuphezulu kunciphisa ukusetshenziswa kukaphethiloli esithandweni kufika ku-20% uma kuqhathaniswa nezihlangu zensimbi.
(2) Ukunciphisa Udoti: Impilo ende yesevisi inqamula udoti wezinto ezibonakalayo ekufakweni kabusha okuvamile.
(3) Ukunciphisa Ubuthi: Khipha isidingo sezingubo eziyingozi (isb., ama-alloys asekelwe ku-nickel) ezindaweni ezibolayo.
I-Shandong Zhongpeng Special Ceramics Co., Ltd ingesinye sezixazululo ezintsha ze-silicon carbide zobumba eChina. I-ceramic yobuchwepheshe ye-SiC: Ubulukhuni be-Moh buyi-9 (ukuqina kwe-Moh entsha yi-13), enokumelana okuhle nokuguguleka nokugqwala, ukuhuzuka okuhle kakhulu – ukumelana ne-oxidation. Impilo yesevisi yomkhiqizo we-SiC iyinde izikhathi ezi-4 kuya kwezi-5 kune-alumina material engu-92%. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi. Inqubo yekhotheshini iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ingeyesibili. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisele izinhliziyo zethu emphakathini.
