Indwangu engagugi ye-silicon carbide: “isivikelo esiqinile” semishini yezimboni

Ezimweni eziyinhloko zokukhiqiza kwezimboni, ukuguguleka nokugqwala kolwelwesi lwemishini kuvame ukuba yiphuzu elibalulekile elithinta ukusebenza kahle kokukhiqiza futhi kwandisa izindleko zokusebenza nokugcinwa. Ukuvela kolwelwesi olungagugi lwe-silicon carbide, kanye nezinzuzo zalo eziyingqayizivele, kuye kwaba yisisombululo esithandwayo sokuxazulula le nkinga, kwakhiwe “isivikelo esiqinile” semishini ehlukahlukene yezimboni.
I-silicon carbidengokwayo iyinto engeyona eyensimbi engaphili enobulukhuni obukhulu kakhulu kanye nokuzinza. Uma isetshenziswa njengendwangu yangaphakathi yemishini yezimboni, izinzuzo zayo eziyinhloko zisezicini zayo ezintathu ezinkulu "zokumelana nokuguguleka, ukumelana nokugqwala, kanye nokumelana nokushisa okuphezulu". Ngokungafani nezinto zondwangu zendabuko, izinto ze-silicon carbide zingaphatha ukuguguleka kanye nokungqubuzana okubangelwa ukuthuthwa kwezinto, ukusabela okuphakathi, kanye nezinye izinqubo kalula. Ngisho nangaphansi kwezimo zokusebenza eziyinkimbinkimbi njengokushisa okuphezulu kanye nokugqwala okunamandla, ingagcina ukuzinza kwesakhiwo, yandise kakhulu impilo yesevisi yemishini, inciphise imvamisa yokugcinwa kwesikhathi sokungasebenzi, futhi yehlise izindleko zokusebenza zesikhathi eside zamabhizinisi.

Ngokombono wezimo zokusetshenziswa, ulwelwesi olungagugi lwe-silicon carbide lufaneleka kakhulu ezimbonini eziningi ezifana nezezimayini, i-metallurgy, ubunjiniyela bamakhemikhali, kanye namandla. Kungakhathaliseki ukuthi luhambisa amapayipi, imikhumbi yokusabela, imishini yokugaya, noma imibhoshongo yokususa i-sulfurization, ikhono lokumelana nokulahlekelwa kwemishini lingathuthukiswa ngokufaka ulwelwesi lwe-silicon carbide. Ukufakwa kwayo okulula kanye nokuzivumelanisa nezimo okuqinile kuvumela ukuthuthukiswa okusheshayo kokuvikela ngaphandle kwesidingo sokuguqulwa okukhulu kwemishini ekhona, okusiza amabhizinisi ukuthuthukisa ukuqhubeka kokukhiqiza kanye nokuzinza.
Njengoba isidingo sokwanda kwemishini esebenza kahle, eyonga amandla, nehlala isikhathi eside emkhakheni wezimboni, ulwelwesi olungagugi lwe-silicon carbide luye lwaba yinto ebalulekile yokusekela ukuthuthukiswa nokuguqulwa kwemishini yezimboni ngenxa yokusebenza kwalo okuhle kakhulu. Esikhathini esizayo, ngokuthuthukiswa okuqhubekayo kwezinqubo zokukhiqiza, ulwelwesi olungagugi lwe-silicon carbide luzodlala indima emasimini ahlukaniswe kakhulu, lunikeze ukwesekwa okuqinile kwentuthuko yezimboni esezingeni eliphezulu.
