Ukuhlola Ulwelwesi Olungamelani Nokugqokwa Kwe-Silicon Carbide: Umqaphi Ongabonakali Wemishini Yezimboni

Emkhakheni wezimboni, imishini ivame ukubhekana nezinselele eziningi ezinzima zemvelo, futhi ukuguga kungenye yezinselelo ezinkulu. Ukuguga akugcini nje ngokunciphisa ukusebenza kahle kwemishini, kodwa futhi kungaholela ekwahlulekeni kwemishini, kwandise izindleko zokulungisa kanye nesikhathi sokungasebenzi. Ukuvela kweulwelwesi olungagugi lwe-silicon carbidekufana nomqaphi ongabonakali, omelana nokuguguleka futhi wandisa isikhathi sokusebenza kwemishini. Namuhla, sizokwembula isembozo sayo esiyimfihlakalo futhi sihlolisise isimiso sayo sokusebenza.
I-Silicon carbide (SiC) iyinhlanganisela eyakhiwe ngezinto ezimbili, i-silicon ne-carbon. Isakhiwo sayo sekristalu sihlukile kakhulu, kanti amayunithi ayisisekelo esakhiwo ahlanganiswe yi-SiC ne-CSi tetrahedra. Lesi sakhiwo esiqinile nesizinzile sinikeza i-silicon carbide izakhiwo eziningi ezinhle kakhulu, njengokumelana nokushisa okuhle, ukumelana nokugqwala, ubulukhuni obuphezulu, kanye nokumelana nokuguguleka, okwenza kube yinto efanelekile yokwenza ulwelwesi olungagugi.
Ngakho-ke, ulwelwesi olungagugi olwenziwe nge-silicon carbide ceramics olusabelayo lusebenza kanjani?
Ubulukhuni obuphezulu bokumelana nokuguguleka: I-Reaction sintered silicon carbide ceramics inobulukhuni obuphezulu kakhulu, okwesibili emva kwedayimane. Lapho izinhlayiya zangaphandle zithinta noma zigudla odongeni lwangaphakathi lwemishini, ulwelwesi olungagugi, olunobulukhuni balo obuphezulu, lungamelana ngempumelelo nomonakalo walezi zinamandla angaphandle, njengesihlangu esiqinile, okunciphisa kakhulu izinga lokuguguleka kwemishini futhi kwandise impilo yemishini.
Ukuqina okuhle kwamakhemikhali ngokumelene nokugqwala: Ezimweni eziningi zezimboni, imishini ayigcini nje ngokuguguleka, kodwa futhi ihlangana namakhemikhali ahlukahlukene, okubeka usongo lokugqwala. I-Reaction sintered silicon carbide ceramics inokuqina okuhle kwamakhemikhali futhi ingavimbela ngempumelelo ukugqwala yizinto zamakhemikhali, ngaleyo ndlela iqinisekise ukusebenza okuvamile kwendwangu engagugi ezindaweni eziyinkimbinkimbi zamakhemikhali.

Ukumelana nokushisa okuphezulu kanye nokuzivumelanisa nezimo zokushisa okuphezulu: Ezinye izinqubo zokukhiqiza zezimboni zingase zikhiqize amazinga okushisa aphezulu, futhi izinto ezivamile zingase zithambile, ziguquguquke, noma zonakale ngisho nasezingeni lokushisa eliphezulu. Kodwa-ke, i-reaction sintered silicon carbide ceramics ingafinyelela izinga lokushisa eliphezulu lokusebenza elingu-1350 ℃ futhi ingasetshenziswa ngokuzinzile isikhathi eside ngisho nakuleli zinga lokushisa eliphezulu. Ingavimbela ngempumelelo izingxenye nezingxenye ukuthi zingabi nokuguquguquka kokushisa kanye nokuthamba ngenxa yokushisa okuphezulu, iqinisekise ukuthi ama-liners angagugi asenganikeza isivikelo esithembekile semishini ezindaweni zokushisa okuphezulu.
Uma kuqhathaniswa nezinye izinhlobo zezinto zokwakha ulwelwesi ezingagugi, ulwelwesi olumelana nokugugiswa lwe-silicon carbide ceramic olunezinzuzo ezisobala. Isibonelo, ubulukhuni balo budlula kakhulu obolwezinto zobumba ezivamile njenge-alumina ne-zirconia, futhi lungcono kakhulu ekumelaneni nokugugiswa; Ukuqina kwalo kwamakhemikhali kanye nokumelana nokushisa okuphezulu nakho kungcono kakhulu kunezinye izinto zendabuko, futhi lungazivumelanisa nezimo zokusebenza eziyinkimbinkimbi nezidinga kakhulu.
Ulwelwesi olungagugi lwe-silicon carbide lusetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana namandla, insimbi, izinto zobumba, ama-oven ashisa kakhulu, izimayini, amalahle, uphethiloli, amakhemikhali kanye nokukhiqizwa kwemishini. Kulezi zimboni, kuvikela amadivayisi amaningi, kuqinisekisa ukukhiqizwa okushelelayo, futhi kunciphisa izindleko zokusebenza kwamabhizinisi.
Ulwelwesi olungagugi lwe-silicon carbide ludlala indima ebalulekile emkhakheni wezimboni ngenxa yesimiso salo esiyingqayizivele sokusebenza kanye nokusebenza okuhle kakhulu. Njengomkhiqizi ochwepheshe we-reaction sintered silicon carbide ceramics, iShandong Zhongpeng ibilokhu izibophezele ekuhlinzekeni amakhasimende ngemikhiqizo esezingeni eliphezulu, isiza izimboni ezahlukahlukene ukuthuthukisa ukusebenza kwemishini, kanye nokufeza ukukhiqizwa okuphumelelayo. Uma unentshisekelo ngemikhiqizo yethu, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi futhi usivumele sihlanganyele ekuthuthukisweni komkhakha ndawonye.
