Kwimveliso yemizi-mveliso, imibhobho ifana “nemibhobho yegazi” ethe gqolo ukuthutha imathiriyeli efana nodaka lwentsimbi, umgubo wamalahle, kunye nentsalela yenkunkuma. Nangona kunjalo, uninzi lwezi zixhobo zineempawu zobunzima obuphezulu kunye nesantya sokuhamba ngokukhawuleza. Imibhobho eqhelekileyo kungekudala iza kugugiswa kukuvuza, okungafuneki nje ukuvalwa rhoqo kunye nokutshintshwa, kodwa kunokubangela iingozi zokhuseleko ngenxa yokuvuza kwezinto. Ukuvela kwemibhobho ye-silicon carbide enganyangekiyo kukusombulula ngokuchanekileyo "ingxaki yokunxiba".
Abanye abantu banokubuza, luhlobo luni lwezinto eziphathekayo "i-silicon carbide"? Enyanisweni, asiyonto intsha. Ngokusisiseko, yimathiriyeli engeyiyo eyentsimbi eyenziwe ngesilicon kunye nezinto zekhabhoni, ezinobunzima besibini kuphela kwidayimane kunye ne-corundum. Uninzi lweesanti eziphakamileyo eziphezulu kunye nezixhobo zokugaya eziqhelekileyo ezisetyenziswa kubomi bemihla ngemihla zisebenzisa i-silicon carbide. Xa le mathiriyeli yokuqina iphakamileyo yenziwa kudonga lwangaphakathi lombhobho, kufana nokubeka umaleko “wedayimani yesikrweqe” kumbhobho. Xa ujongene nezinto eziphezulu zokugqoka, unokuchasa ngokuthe ngqo impembelelo kunye nokukhuhlana kwezinto, ngokusisiseko ukwandisa ubomi benkonzo yombhobho.
Xa kuthelekiswa nemibhobho yemveli, izibonelelo ze-silicon carbide ukunxiba-resistant imibhobho iya ngaphaya "kokuxhathisa ukunxiba". Imibhobho yentsimbi eqhelekileyo igutyungelwa lula ngezinto ezityiwayo ngexesha lothutho, kwaye imibhobho yeplastiki inzima ukumelana nobushushu obuphezulu kunye noxinzelelo. Nangona kunjalo, izixhobo ze-silicon carbide ngokwazo zineempawu zokumelana ne-asidi kunye ne-alkali kunye nokumelana nobushushu obuphezulu. Ingaba zihambisa i-acidic slurry okanye i-high-temperature powder yamalahle, zinokusebenza ngokuzinzile ngaphandle kokukhathazeka rhoqo malunga "ne-corrosion perforation" okanye "i-deformation ephezulu yokushisa". Okubaluleke ngakumbi, udonga lwayo lwangaphakathi luhamba kakuhle, okwenza kube lula ukuqokelela kunye nokuvala ngexesha lokuthutha izinto eziphathekayo, ukunciphisa ubunzima bokucoca imibhobho kunye nokuqinisekisa ukuqhubeka kwemveliso.
Kule mihla, kumashishini afana nemigodi, umbane, kunye nobunjineli beekhemikhali ezifuna ukuxhathisa okuphezulu kakhulu kwimibhobho, imibhobho ye-silicon carbide enganyangekiyo ngokuthe ngcembe ithathe indawo yemibhobho yemveli. Akukho mfuneko yokuba itshintshwe rhoqo emva kweenyanga ezintandathu njengemibhobho eqhelekileyo, kwaye ayifuni zindleko zokuyilungisa ngokuphindaphindiweyo. Nangona utyalo-mali lokuqala lunokubonakala luphezulu kancinci, lunceda ishishini ukonga iindleko ezininzi ekuhambeni kwexesha. Kumashishini afuna imveliso esebenzayo kunye nezinzileyo, ukukhetha i-silicon carbide-resistant mibhobho ngokwenene kukhetha isisombululo sothutho "sokukhathazeka kancinci, ixesha elide".
Ngokunyuka kwemfuno yokuqina kwezixhobo kunye nokhuseleko kwimveliso yemizi-mveliso, iimeko zokusetyenziswa kwemibhobho ye-silicon carbide enganyangekiyo ikhula rhoqo. Isombulula ingxaki "endala kwaye inzima" ekuthuthweni kwemizi-mveliso kunye nokusebenza okuqinileyo kwezinto eziphathekayo ngokwayo, kwaye inika amashishini amaninzi ngokukhetha okuthembekileyo kwindlela yokunciphisa iindleko kunye nokuphucula ukusebenza kakuhle.
