Emkhakheni wokukhiqiza wezimboni osezingeni eliphezulu, isidingo sezingxenye ezibunjiwe ngokwezifiso siyakhula usuku nosuku. Lezi zingxenye eziyinkimbinkimbi ezibunjiwe nezifuna ukunemba zinquma ngqo ukusebenza kanye nesikhathi sokuphila kwemishini. Njengoba zibhekene nokuhlolwa okuningi njengokushisa okuphezulu, ukugqwala, kanye nokuguguleka, izinto zensimbi zendabuko zivame ukwehluleka, kuyilapho uhlobo olusha lwezinto zobumba olubizwa ngokuthi “i-silicon carbide ephendukile yokusabela"Iba yinto ethandekayo embonini buthule."
1, 'Uchwepheshe oguquguqukayo' ezindaweni ezibucayi
Isici esivelele kakhulu se-reaction sintered silicon carbide (RBSiC) ukumelana kwayo nokuphathwa. Ingabhekana kalula namazinga okushisa aphezulu angu-1350 ℃, okuyizinga lokushisa eliphindwe kabili kunensimbi evamile; Izungezwe izinto ezibola kakhulu, ukumelana kwayo nokugqwala kunamandla ayishumi kunensimbi engagqwali. Lesi sici "sensimbi nensimbi" senza kube ukukhetha okuhle kwezimo zokusebenza ezinzima njengezimboni zamakhemikhali nezensimbi. Okungavamile nakakhulu ukuthi ukumelana kwayo nokuguguleka kufana ne-alloy eqinile, kodwa isisindo sayo silula kunensimbi, okunciphisa kakhulu ukusetshenziswa kwamandla kwemishini.
2, 'Umfundi oyisibonelo' wokwenza ngokwezifiso ngokunemba
Ezingxenyeni ezingavamile ezibunjwe ngendlela eyinkimbinkimbi, i-silicon carbide e-reaction sintered ibonisa i-plasticity emangalisayo. Ngobuchwepheshe bokwenza isikhunta ngokunemba, ukunemba okuphezulu kakhulu kungatholakala, futhi cishe akukho ukucutshungulwa kwesibili okudingekayo ngemva kokusila. Lesi sici "sokubumba kanye" sifaneleka kakhulu ekukhiqizeni izingxenye zokunemba ezifana nama-turbine blades, ama-nozzle, amasongo okuvala, njll., okusiza amakhasimende ukuthi onge kakhulu izindleko zokucubungula.
3, 'iqembu elihlala njalo' eliwusizo ngokwezomnotho
Nakuba izindleko zento eyodwa ziphakeme kancane kunezezinto ezivamile, impilo yayo yokusebenza ingaba izikhathi eziningana kunezingxenye zensimbi. Ezimweni ezifana namapayipi amakhulu emisebe namapayipi amelana nokuguguleka enziwe ngokwezifiso, izingxenye ezenziwe ngale nto zingasebenza ngokuqhubekayo amahora angamashumi ezinkulungwane ngaphandle kwesidingo sokushintshwa. Isici "sokuthenga okubizayo nokusebenzisa okushibhile" siholele amabhizinisi amaningi ukuthi aqale ukubala ama-akhawunti ezomnotho esikhathi eside.
Njengomhlinzeki wesevisi yezobuchwepheshe ohileleke kakhulu emkhakheni we-reaction sintered silicon carbide, iShandong Zhongpeng ihlala izibophezele ekuhlinzekeni amakhasimende ngezixazululo "ezenziwe ngokwezifiso". Kusukela ocwaningweni lwezinto ezibonakalayo kanye nentuthuko kuya ekusetshenzisweni kobuchwepheshe obunembile, kusukela ekuhlolweni kokusebenza kuya ekuqondisweni kwesicelo, yonke isixhumanisi imelela ukuphishekela ukusebenza okuphezulu. Ukukhetha thina akukhona nje ukukhetha izinto ezithuthukisiwe, kodwa futhi nokukhetha umlingani othembekile wesikhathi eside. Nikeza izixazululo ezinhle kakhulu ezinseleleni zemishini ngaphansi kwezimo zokusebenza eziyinkimbinkimbi.
