Ezicini eziningi zokukhiqiza kwezimboni, ukuguguleka kwemishini bekulokhu kuyisici esibalulekile esithinta ukusebenza kahle kokukhiqiza kanye nezindleko. Ukuze kuxazululwe le nkinga, kuye kwavela izinto ezahlukahlukene ezingagugi, phakathi kwazo i-silicon carbide engagugi, kancane kancane ibe "intandokazi entsha" emkhakheni wezimboni ngenxa yokusebenza kwayo okuhle kakhulu. Namuhla, ake sihlolisise le nto yomlingo.
1, Kuyiniulwelwesi olungagugi lwe-silicon carbide?
I-Silicon carbide (i-SiC) iyinhlanganisela eyakhiwe yi-silicon ne-carbon, enesakhiwo sekristalu esiyingqayizivele nesizinzile. Amayunithi ayo ayisisekelo esakhiwo ahlanganiswe yi-SiC ne-CSi tetrahedra. I-silicon carbide engagugi ingqimba evikelayo eyenziwe ngezinto ze-silicon carbide ukuvikela ingaphakathi lemishini ekugugeni nasekudabukeni. Ingenziwa ibe yizimo ezahlukahlukene, njengendandatho ze-ceramic, ama-ceramic liners, njll., bese ifakwa ezindongeni zangaphakathi zemishini efana namapayipi, imizimba yepompo, kanye nama-silo avame ukuguguleka nokungqubuzana kwezinto.
2. Izinzuzo ze-silicon carbide engagugi
1. Ubulukhuni obuphezulu kanye nokumelana nokuguguleka okukhulu: Ubulukhuni be-silicon carbide ceramics buphezulu kakhulu, bulandela idayimane elinzima kakhulu ngokwemvelo. Lobu bunzima obuphezulu buyinika ukumelana nokuguguleka okunamandla kakhulu, ikwazi ukumelana nokuguguleka okusheshayo kanye nokungqubuzana okunamandla kwezinto, kwandisa kakhulu impilo yesevisi yemishini, okwenza ibe yinto efanelekile yokulwa nokuguguleka emkhakheni wokuguga okunzima. Uma kuqhathaniswa nezinye izinto ezivamile ezingaguguleki, ulwelwesi olungaguguleki lwe-silicon carbide lunezinzuzo ezibalulekile ekumelaneni nokuguguleka, okunganciphisa imvamisa yokugcinwa nokufakwa esikhundleni kwemishini kwamabhizinisi kanye nezindleko zokukhiqiza eziphansi.
2. Ubuningi obuphansi kanye nesisindo esilula: I-silicon carbide inobuningi obuphansi kakhulu kunezinsimbi ezifana nensimbi. Isibonelo, ubuningi be-reaction sintered silicon carbide ceramics bungu-3.0g/cm³ kuphela, kanti ubuningi be-sintered silicon carbide ceramics bungu-3.14-3.0g/cm³. Uma kwenzeka ivolumu efanayo, isisindo se-silicon carbide engagugi i-lining ilula, okungenzi nje kuphela ukuthi kube lula ukuthuthwa nokufakwa, kodwa futhi kunciphisa umthwalo wemishini, okwenza ukusebenza kwemishini kube lula, futhi kuvumela ukufakwa kwamapayipi neminye imishini ukuba kuphakame kakhulu.
3. Ukumelana nokushisa okuphezulu: Iqinile kahle ekushiseni futhi isakhiwo sekristalu esiyingqayizivele se-silicon carbide siyivumela ukuthi imelane nokushisa okuphezulu, ngokushisa okushisayo okufika ku-1350 ℃. Lesi sici senza ukuthi ulwelwesi olungagugi lwe-silicon carbide lugcine ukusebenza okuzinzile ngisho nasezindaweni zokushisa okuphezulu, ngaphandle kokuguquka noma ukulimala ngenxa yokushisa okuphezulu, okwenza ifaneleke ezimweni ezahlukene zezimboni zokushisa okuphezulu njenge-metallurgy, amandla kanye nezinye izimboni.
4. Ukumelana nokugqwala: I-Silicon carbide inezakhiwo zamakhemikhali ezizinzile futhi ingabonisa ukumelana okuhle nokugqwala lapho ibhekene nezinto ezahlukahlukene zamakhemikhali. Kungakhathaliseki ukuthi ithuthwa yi-acidic ne-alkaline enamandla ekukhiqizweni kwamakhemikhali noma emkhakheni wokuvikelwa kwemvelo njengokwelashwa kwendle, ulwelwesi olungagugi lwe-silicon carbide lungavikela imishini ngokuthembekile, luvimbele imishini ukuthi ingagqwali yizinto zamakhemikhali, futhi lwandise isikhathi senkonzo yemishini.
5. Ukuqina komoya okubuthakathaka kanye nokungaguquguquki: Izitsha zobumba ze-silicon carbide zinamandla okuqina komoya okubuthakathaka, okwenza zifaneleke ukusetshenziswa ngezidingo eziqinile zikagesi ongaguquki, njengezindawo zokusebenzela ezingaqhumi. Kulezi zimo, ugesi ongaguquki ungabangela izingozi ezinkulu zokuphepha, futhi umsebenzi wokungaguquguquki wendwangu engaguquki ye-silicon carbide ungavimbela ngempumelelo ukuqongelela kukagesi ongaguquki futhi uqinisekise ukuphepha kokukhiqiza.
6. Kulula ukwakheka, okwazi ukucubungula izingxenye ezinkulu neziyinkimbinkimbi ezibunjiwe: I-silicon carbide ingacutshungulwa kusetshenziswa izinqubo ezifana nokusabela kokusila, okunikeza izinzuzo ezinkulu ekubunjweni. Ngale nqubo, kungakhiqizwa izinto zobumba ezinkulu kanye nezinto zobumba eziyinkimbinkimbi ezibunjiwe. Lokhu kusho ukuthi kungakhathaliseki ukuthi isimo nobukhulu bemishini bukhetheke kangakanani, ulwelwesi olumelana nokuguguleka lwe-silicon carbide lungalungiswa kahle ukuze luhlangabezane nezidingo zemishini ehlukene yezimboni.
Ulwelwesi olungagugi lwe-silicon carbide lubonise inani elikhulu lokusetshenziswa emkhakheni wezimboni ngenxa yezinzuzo zalo eziningi. Ngokuthuthuka okuqhubekayo kanye nentuthuko yesayensi yezinto zokwakha, kukholelwa ukuthi ulwelwesi olungagugi lwe-silicon carbide luzosetshenziswa emikhakheni eminingi, lunikeze ukwesekwa okuqinile kokusebenza okuphumelelayo nokuzinzile kokukhiqiza kwezimboni. Uma unesithakazelo kulwelwesi olungagugi lwe-silicon carbide, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi ukuze uhlole izimfihlo ezengeziwe mayelana nobumba be-silicon carbide ndawonye.
