Ukushisisa kuyisinyathelo esibalulekile kodwa esibalulekile ezicini eziningi zokukhiqizwa kwezimboni. Kusukela ekwelashweni kokushisa kwensimbi kuya ku-ceramic sintering, ngisho nokucutshungulwa kwezinto ezithile ezikhethekile, umshini wokushisa ozinzile, osebenza kahle futhi oguquguqukayo uyadingeka. Kulezi zimo ezinezidingo eziqinile zokushisa nokuqina,emisebeni ye-silicon carbideamashubhu aba ukukhethwa kwamabhizinisi amaningi ngokwengeziwe ngenxa yezinzuzo zawo eziyingqayizivele.
Abanye abantu bangase babe nelukuluku, liyini ishubhu le-silicon carbide radiation? Kalula nje, kuyisici sokushisa se-tubular esenziwe ikakhulukazi ngamaceramics e-silicon carbide, ngokuvamile asetshenziswa ngokuhambisana nezintambo zokushisa, izinduku zokufudumeza nezinye izinto zangaphakathi, futhi idlala indima "ye-heat exchanger" kuhhavini lezimboni nezinye izinto zokusebenza. Kodwa-ke, ukuhluka kwayo kuwukuthi akukhiqizi ngokuqondile izinga lokushisa eliphezulu, kodwa kunalokho ngokulinganayo idlulisela ukushisa endaweni yokusebenza edinga ukushiswa ngendlela yemisebe ngokusebenzisa izakhi zokushisa zangaphakathi eziboshwe nxazonke, kuyilapho futhi ivikela izingxenye zangaphakathi emkhathini oyinkimbinkimbi ngaphakathi kwesithando somlilo.
Uma kukhulunywa ngezinzuzo zamashubhu emisebe ye-silicon carbide, "ukumelana nezinga lokushisa eliphezulu" nakanjani ilebula layo eliyinhloko. Amashubhu okushisa ensimbi avamile angase ahlangane ne-deformation kanye ne-oxidation emazingeni okushisa angamakhulu ambalwa degrees Celsius, kuyilapho izitsha zobumba ze-silicon carbide ngokwazo zinokumelana okuhle kakhulu nezinga lokushisa eliphezulu. Nakuma-kilns ashisa kakhulu ngaphezu kuka-1300 ℃, angagcina ukuqina kwesakhiwo futhi awonakele kalula. Lesi sici siyivumela ukuthi ivumelane nezimo eziningi zokucubungula izinga lokushisa eliphezulu, njengezinga lokushisa elishisayo lezinye izitsha zobumba ezikhethekile ngokuvamile elingaphezu kuka-1200 ℃, namashubhu emisebe ye-silicon carbide angasebenza ngokwethembeka ezindaweni ezinjalo isikhathi eside.
Ngaphezu kokumelana nokushisa okuphezulu, "ukumelana nokugqwala" nakho kuyisici esivelele kukho. Ezinqubweni eziningi zokushisisa ezimbonini, kungase kube ne-acidic, amagesi ane-alkaline noma ezinye izinto ezigqwalayo kuhhavini, ezingagqwala kalula izinto zokushisisa futhi zifinyeze impilo yesevisi yezinto zokusebenza. Ukuzinza kwamakhemikhali we-silicon carbide material kunamandla, futhi akulula ukusabela ngalezi zinto ezonakalisayo, okusho ukuthi ingagcina ukuqina okuhle ezindaweni eziyinkimbinkimbi zokushisa, inciphise imvamisa yokushintshwa kwemishini, futhi ngokuhamba kwesikhathi, iphinde yehlise izindleko zokukhiqiza nezokugcina amabhizinisi.
Ngaphezu kwalokho, "ukusebenza kahle okushisayo" kwamashubhu emisebe ye-silicon carbide nakho kufanele kukhulunywe. I-conductivity yayo yokushisa inhle, engadlulisa ngokushesha ukushisa okukhiqizwa yizici zokushisa zangaphakathi futhi ishise i-workpiece ngemisebe. Le ndlela yokushisa ayigcini nje ukushisa ngokushesha, kodwa futhi yenza ukusatshalaliswa kwezinga lokushisa ngaphakathi kwehhavini kufane kakhulu, kugweme ukushisa kwendawo noma izinga lokushisa elinganele. Lokhu kubaluleke kakhulu ekuqinisekiseni ukuhambisana kwekhwalithi yokucubungula umkhiqizo. Isibonelo, ekwelapheni ukushisa kwezingxenye zensimbi, ukufana kwezinga lokushisa kuthinta ngokuqondile ukuqina, ukuqina, nezinye izakhiwo zezingxenye, futhi amashubhu emisebe ye-silicon carbide anganikeza ukusekela okuzinzile kulokhu.
Yiqiniso, ukusetshenziswa kwamashubhu emisebe ye-silicon carbide akunamingcele. Isibonelo, izindleko zabo ziphakeme kakhulu kunezinsimbi ezivamile zokushisa amashubhu, futhi ngenxa yezici zezinto ze-ceramic, zidinga ukugwema ukungqubuzana okukhulu ngesikhathi sokufakwa nokusetshenziswa ukuvimbela umonakalo. Kodwa ezimbonini ezinezidingo eziphezulu zokushisisa, ukugqwala kwemvelo, kanye nekhwalithi yomkhiqizo, ukuzinza, ukusebenza kahle, nokuphila okude okulethayo kuvame ukunxephezela lezi zinkinga ezincane.
Ezinsukwini zanamuhla, ngokuthuthukiswa kokukhiqizwa kwezimboni ekuqondeni okuthe xaxa kanye nokuphela okuphezulu, izidingo zemishini yokushisa nazo zikhula njalo. Njengento enhle kakhulu yokufudumala yezimboni, amashubhu e-silicon carbide radiation kancane kancane adlala indima enkulu emikhakheni efana ne-ceramics, i-metallurgy, ne-electronics. Ingase ingabukeki njengobuchwephesha obuthile obusafufusa, kodwa yiyo kanye le mfanelo “yokunamathela kokuthunyelwe kwayo” buthule ezindaweni ezidlulele okuyenza ibe “uchwepheshe omelana nokushisa okuphezulu” ekukhiqizweni kwezimboni, enikeza iziqinisekiso ezinokwethenjelwa zezinqubo zokushisisa ezifunwa kakhulu.
