Kwiindawo zemveliso yemizi-mveliso, imibhobho “yindlela yokuphila” yokuthutha izinto. Nangona kunjalo, xa ijongene nokukhukuliseka kunye nokuguga kwezinto eziqinileyo ezifana nesanti, udaka, kunye nenkunkuma, imibhobho eqhelekileyo idla ngokufumana ukuvuza kunye nokonakala kwixesha elifutshane. Oku akudingi nje kuphela ukuvalwa rhoqo kunye nokutshintshwa, kodwa kunokubangela neengozi zokhuseleko. Phakathi kwemibhobho emininzi engagugiyo, imibhobho engagugiyo ye-silicon carbide ibe yinto eshushu kwicandelo lemizi-mveliso ngenxa yokumelana kwayo nokuguguleka okuphezulu. Namhlanje, siza kuthetha ngalo “mdlali oqinileyo” kushishino lwemibhobho.
Abantu abaninzi basenokungaqhelananga ne-silicon carbide. Ngamafutshane, yinto engeyoyasemethini engaphiliyo enobunzima obungaphezulu kwedayimani, kwaye ngokwendalo ineempawu "zokuthintela ukwenziwa". Umbhobho onganyangekiyo owenziwe ngawo ufana nokubeka umaleko "wesivikelo sedayimani" kumbhobho, onokumelana lula nempembelelo yemidiya eyahlukeneyo yokuguguleka okuphezulu.
Xa kuthelekiswa nemibhobho yentsimbi yendabuko kunye nemibhobho yeseramikhi, iingenelo zeimibhobho engagugiyo ye-silicon carbidezibonakala kakhulu. Okokuqala, inokumelana nokuguguleka ngokupheleleyo. Nokuba ithutha udaka olunesanti ye-quartz okanye intsalela yenkunkuma enamasuntswana aqinileyo, inokugcina umgangatho wayo usemgangathweni kwaye inobomi benkonzo obude amaxesha amaninzi kunemibhobho yentsimbi eqhelekileyo, nto leyo enciphisa kakhulu ukuphindaphindeka kunye neendleko zokutshintshwa kwemibhobho. Okwesibini, inokumelana nokugqwala okunamandla. Izixhobo zoshishino zihlala ziqulathe izinto ezigqwala ezifana ne-asidi kunye ne-alkali, kwaye imibhobho eqhelekileyo ithambekele ekugqwaleni nasekugugeni. Nangona kunjalo, i-silicon carbide ngokwayo ineempawu zeekhemikhali ezizinzileyo kwaye inokumelana nokugqwala kwe-asidi kunye ne-alkali media ezahlukeneyo, nto leyo eyenza ifaneleke kwiindawo zokusebenza ezinzima ngakumbi.
Ukongeza, iipayipi ezingagugiyo ze-silicon carbide nazo zinophawu olucingisisiweyo - ukuqhuba kakuhle kobushushu, okunokususa ubushushu ngokukhawuleza xa kuthuthwa izinto ezishushu kakhulu, kuthintelwe ukuguquguquka kwemibhobho okubangelwa kubushushu obuphezulu bendawo, kwaye kuncitshiswe ukulahleka kobushushu, kunciphisa ngokungathanga ngqo ukusetyenziswa kwamandla emveliso. Ngaphezu koko, ulwakhiwo lwayo oluncinci luyenza ingahlukanga kangako kwimibhobho eqhelekileyo xa ifakiwe, ngaphandle kwesidingo sokutshintshwa kwezixhobo ezongezelelweyo. Inobunzima obuncinci ekuqaliseni kwaye inokuqhelana ngokulula neeprojekthi zokwakha ezintsha kunye nokuhlaziywa kwemibhobho endala.
Kule mihla, iipayipi ezingagugiyo ze-silicon carbide zisetyenziswa kakhulu kumashishini ahlukeneyo afana nokwemba imigodi, i-metallurgy, umbane, kunye nobunjineli beekhemikhali, ezifana nokuthuthwa kodaka kwimigodi, iinkqubo zokususa i-sulfurization kunye ne-denitrification kwizityalo zamandla, kunye nokuthuthwa kweentsalela zenkunkuma kushishino lwe-metallurgical, apho ubukho bazo bunokubonwa khona. Ayisombululi nje kuphela iindawo ezibuhlungu zemibhobho yendabuko enokuguguleka nokubola, kodwa ikwanceda amashishini ukunciphisa ixesha lokungasebenzi, ukunciphisa iindleko zokulungisa, kunye nokuphucula ukusebenza kakuhle kwemveliso, ibe "sisixhobo esingagugiyo" esibalulekileyo kwicandelo lemizi-mveliso.
Ngenxa yophuhliso oluqhubekayo lwetekhnoloji yemizi-mveliso, ukusetyenziswa kwezinto ze-silicon carbide kusakhula. Sikholelwa ukuba kwixesha elizayo, imibhobho engagugiyo ye-silicon carbide iya kukhupha ukukhanya nobushushu kwiindawo ezihlukeneyo, nto leyo enika ukhuseleko lokusebenza okuzinzileyo kwemveliso yemizi-mveliso.
