Kwintsimi enkulu yesayensi yezinto eziphathekayo,iimveliso ze-silicon carbidengokuthe ngcembe ziba “ziintandane” kumashishini amaninzi ngenxa yeempawu zazo ezikhethekileyo. Ingakumbi ukumelana nokuguguleka kwayo okugqwesileyo kwenza ikhanye kwiindlela ezahlukeneyo zokusebenza. Namhlanje, makhe sijonge kunye ukumelana nokuguguleka kweemveliso ze-silicon carbide.
I-silicon carbide, ngokwembono yokwakheka kweekhemikhali, yi-compound eyenziwe ngezinto ezimbini, i-silicon kunye ne-carbon, kumaqondo obushushu aphezulu. Ulwakhiwo lwayo lwekristale luhlukile kakhulu, olunika i-silicon carbide uluhlu lweempawu ezintle, kwaye ubunzima obuphezulu busisiseko sokumelana kwayo nokuguguleka. Ubunzima be-silicon carbide buphezulu kakhulu, bunobunzima be-Mohs obumalunga ne-9.5, obungaphantsi kancinci kunedayimani enzima kakhulu. Ubunzima obuphezulu obunjalo buthetha ukuba inokumelana ngempumelelo nokuguguleka kwangaphandle, kwaye isagcina ingqibelelo yayo kunye nokuzinza kokusebenza xa ijongene neendawo ezahlukeneyo zokusetyenziswa ezinzima.
Ngokwembono yemicroscope, isakhiwo seemveliso ze-silicon carbide sixinene kakhulu. Akukho mingxunya mikhulu okanye iziphene ngaphakathi, nto leyo eyenza ukuba kungabi lula ukwenzakala kwesakhiwo kunye nokuqhekeka kwezinto xa zingqubana. Ifana nenqaba eqinileyo, eneendonga ezidityaniswe ngokuqinileyo ezinzima ukuba iintshaba zigqobhoze. Xa kukho ukungqubana phakathi kwezinto zangaphandle kunye nomphezulu we-silicon carbide, isakhiwo sayo esixineneyo sinokusasaza amandla okungqubana, kuthintelwe ukuguguleka kwendawo okubangelwa kukuxinana koxinzelelo, kwaye kuphucule kakhulu ukumelana nokuguguleka ngokubanzi.
Uzinzo lweekhemikhali lukwasisixhobo esikhulu sokumelana nokuguguleka kwe-silicon carbide. Kwiimeko ezininzi zokusetyenziswa, izixhobo azimelani nje kuphela nokuguguleka koomatshini, kodwa zinokujamelana nokuguguleka kweekhemikhali. I-silicon carbide inozinzo oluhle kakhulu lweekhemikhali, kwaye ayichaphazeleki ziikhemikhali nezinye izinto ezinokubangela ukuguguleka kokusebenza, nokuba zikwimeko yeekhemikhali ezigqwalisayo okanye phantsi kweemeko ezinzima ezifana namaqondo obushushu aphezulu. Nokuba phantsi kweemeko ezinzima zobushushu obuphezulu kunye nokugqwala ixesha elide, iimveliso ze-silicon carbide zisenokugcina ubulukhuni bazo kunye nokuqina kwesakhiwo, kwaye ziqhubeke nokubonisa ukumelana nokuguguleka okuhle.
Kwizicelo ezisebenzayo, iingenelo zokuxhathisa ukuguguleka kweemveliso ze-silicon carbide zibonakaliswa ngokupheleleyo. Kwishishini lezemigodi, i-silicon carbide idla ngokusetyenziswa ukuvelisa izixhobo zezemigodi ezifana neebhithi zokubhola, izixhobo zokusika, njl. Ezi zixhobo kufuneka zimelane noxinzelelo olukhulu loomatshini kunye nokungqubana rhoqo ngexesha lenkqubo yokumba i-ore eqinileyo, ngelixa i-silicon carbide, enokumelana nokuguguleka okuphezulu, inokwandisa kakhulu ubomi benkonzo yezixhobo, inciphise ukuphindaphindeka kokutshintshwa kwezixhobo, kwaye inciphise iindleko zokwemba. I-Silicon carbide ikwasetyenziswa kakhulu ekutywineni izinto, iibheringi, kunye nezinye iindawo zoomatshini bemizi-mveliso. Inganciphisa ngempumelelo ukuguguleka kwezi zinto ngexesha lokusebenza ngesantya esiphezulu kunye nokungqubana rhoqo, iphucule ukusebenza kakuhle kunye nokuzinza kwezixhobo, kwaye inciphise iindleko zokulungisa.
Ukumelana nokuguguleka kweemveliso ze-silicon carbide kuxhomekeka kulwakhiwo lwazo lweekhemikhali olukhethekileyo, ulwakhiwo lwekristale, kunye neempawu ezincinci. Ngokuqhubeka kweteknoloji kunye nophando olunzulu kwi-silicon carbide, sikholelwa ukuba iimveliso ze-silicon carbide ziya kusetyenziswa kwiindawo ezininzi, zizise amathuba amatsha kunye notshintsho kuphuhliso lwamashishini ahlukeneyo.
