Emkhakheni omkhulu wesayensi yezinto ezibonakalayo,imikhiqizo ye-silicon carbidekancane kancane ziba “isithandwa” sezimboni eziningi ngenxa yezakhiwo zazo ezihlukile. Ikakhulukazi ukumelana kwayo nokuguguleka okuhle kakhulu kwenza ikhanye ezinhlotsheni ezahlukene zokusebenza. Namuhla, ake sihlole ukumelana nokuguguleka kwemikhiqizo ye-silicon carbide ndawonye.
I-silicon carbide, ngokombono wokwakheka kwamakhemikhali, iyinhlanganisela eyenziwe ngezinto ezimbili, i-silicon ne-carbon, emazingeni okushisa aphezulu. Isakhiwo sayo sekristalu sihlukile kakhulu, esihlinzeka nge-silicon carbide ngochungechunge lwezakhiwo ezinhle kakhulu, futhi ubulukhuni obuphezulu buyisisekelo esiyinhloko sokumelana kwayo nokuguguleka. Ubulukhuni be-silicon carbide buphakeme impela, bunobulukhuni be-Mohs obungaba ngu-9.5, obuphansi kancane kunedayimane elinzima kakhulu ngokwemvelo. Ubulukhuni obunjalo busho ukuthi ingamelana ngempumelelo nokuguguleka kwangaphandle, futhi isalondoloze ubuqotho bayo kanye nokuqina kokusebenza lapho ibhekene nezimo ezahlukene zokusetshenziswa ezinzima.
Ngokombono omncane kakhulu, isakhiwo esincane semikhiqizo ye-silicon carbide siminyene kakhulu. Cishe azikho izimbobo ezinkulu noma amaphutha ngaphakathi, okwenza kube lula ukuthi kube nomonakalo wesakhiwo kanye nokuqhekeka kwezinto lapho kungqubuzana. Kufana nenqaba eqinile, enezindonga ezixhunywe ngokuqinile okunzima ukuthi izitha zingene kuzo. Uma kukhona ukungqubuzana phakathi kwezinto zangaphandle kanye nobuso be-silicon carbide, isakhiwo sayo esiminyene singasabalalisa amandla okungqubuzana, sigweme ukuguguleka kwendawo okubangelwa ukugxilisa ingqondo, futhi sithuthukise kakhulu ukumelana nokuguguleka okuphelele.
Ukuzinza kwamakhemikhali nakho kuyisikhali esikhulu sokumelana nokuguguleka kwe-silicon carbide. Ezimweni eziningi zokusetshenziswa okusebenzayo, izinto azigcini nje ngokumelana nokuguguleka komshini, kodwa zingase zibhekane nokuguguleka kwamakhemikhali. I-Silicon carbide inokuqina kwamakhemikhali okuhle kakhulu, futhi ayithambekeli ekubhekaneni namakhemikhali nezinye izinto ezingabangela ukuwohloka kokusebenza, kungakhathaliseki ukuthi ezindaweni zamakhemikhali ezigqwalisayo noma ngaphansi kwezimo ezimbi kakhulu njengamazinga okushisa aphezulu. Ngisho nangaphansi kwezimo ezinzima zokushisa okuphezulu nokugqwala isikhathi eside, imikhiqizo ye-silicon carbide isakwazi ukugcina ubulukhuni bayo kanye nokuqina kwesakhiwo, futhi iqhubeke nokubonisa ukumelana okuhle nokugqwala.
Ezisetshenzisweni ezisebenzayo, izinzuzo zokumelana nokuguguleka kwemikhiqizo ye-silicon carbide zibonakala ngokugcwele. Embonini yezimayini, i-silicon carbide ivame ukusetshenziselwa ukukhiqiza amathuluzi okumba njengezinsimbi zokubhoboza, amathuluzi okusika, njll. Lawa mathuluzi adinga ukumelana nokucindezeleka okukhulu kwemishini kanye nokungqubuzana okuvamile ngesikhathi senqubo yokumba ama-ore aqinile, kuyilapho i-silicon carbide, enokumelana kwayo nokuguguleka okuphezulu, ingandisa kakhulu impilo yesevisi yamathuluzi, inciphise imvamisa yokushintsha amathuluzi, futhi yehlise izindleko zokumba. I-Silicon carbide iphinde yasetshenziswa kabanzi ekuvaleni izingxenye, amabheringi, nezinye izingxenye zemishini yezimboni. Inganciphisa ngempumelelo ukuguguleka kwalezi zingxenye ngesikhathi sokusebenza ngesivinini esikhulu kanye nokungqubuzana okuvamile, ithuthukise ukusebenza kahle kanye nokuzinza kwemishini, futhi inciphise izindleko zokulungisa.
Ukumelana nokuguguleka kwemikhiqizo ye-silicon carbide kunqunywa ukwakheka kwayo kwamakhemikhali okuhlukile, isakhiwo sekristalu, kanye nezici ezincane kakhulu. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nocwaningo olujulile nge-silicon carbide, sikholelwa ukuthi imikhiqizo ye-silicon carbide izosetshenziswa emikhakheni eminingi, ilethe amathuba amasha kanye nezinguquko ekuthuthukisweni kwezimboni ezahlukahlukene.
