Kwimveliso yemizi-mveliso, imibhobho ifana “nemithambo yegazi” eqhubeka ithutha izinto ezifana ne-ore slurry, umgubo wamalahle, kunye nenkunkuma eseleyo. Nangona kunjalo, uninzi lwezi zinto zineempawu zobunzima obuphezulu kunye nesantya sokuhamba ngokukhawuleza. Imibhobho eqhelekileyo iza kuguga kungekudala ngenxa yokuvuza, okungadingi nje kuphela ukuvalwa rhoqo nokutshintshwa, kodwa kunokubangela neengozi zokhuseleko ngenxa yokuvuza kwezinto. Ukuvela kwemibhobho engagugiyo ye-silicon carbide ngokuchanekileyo kukusombulula “ingxaki yokuguguleka”.
Abanye abantu banokubuza, loluphi uhlobo lwento "yi-silicon carbide"? Enyanisweni, ayisiyonto intsha. Ngokwenyani, yinto engeyiyo i-metallic engeyiyo i-inorganic eyenziwe ngezinto ze-silicon kunye ne-carbon, enobunzima obulandela idayimani kunye ne-corundum kuphela. Ii-sandpaper ezininzi eziphezulu kunye nezixhobo zokugaya ezisetyenziswa rhoqo kubomi bemihla ngemihla zisebenzisa i-silicon carbide. Xa le nto inzima kakhulu yenziwe eludongeni lwangaphakathi lombhobho, kufana nokubeka umaleko "we-diamond armor" kumbhobho. Xa ijongene nezinto ezigugileyo, inokumelana ngokuthe ngqo nempembelelo kunye nokungqubana kwezinto, ngokusisiseko yandise ubomi benkonzo yombhobho.
Xa kuthelekiswa nemibhobho yendabuko, iingenelo zemibhobho engagugiyo ye-silicon carbide zidlula "ukungagugi". Imibhobho yentsimbi eqhelekileyo idla ngokugqwala lula zizinto ezigqwala ngexesha lokuthuthwa, kwaye imibhobho yeplastiki kunzima ukuyinyamezela amaqondo obushushu aphezulu kunye noxinzelelo. Nangona kunjalo, izinto ze-silicon carbide ngokwazo zineempawu zokungagugi kwe-asidi kunye ne-alkali kunye nokungagugi kobushushu obuphezulu. Nokuba zithutha i-asidi slurry okanye i-powder yamalahle enobushushu obuphezulu, zinokusebenza ngokuzinzileyo ngaphandle kwenkxalabo rhoqo malunga "nokugqobhoka kokugqwala" okanye "ukuguquguquka kobushushu obuphezulu". Okubaluleke ngakumbi, udonga lwayo lwangaphakathi lugudile, okwenza kungabi lula ukuqokelelana nokuvaleka ngexesha lokuthuthwa kwezinto, kunciphisa ubunzima bokucoca imibhobho kunye nokuqinisekisa ukuqhubeka kwemveliso.
Kule mihla, kumashishini afana nemigodi, umbane, kunye nobunjineli beekhemikhali ezifuna ukumelana nokuguguleka okuphezulu kakhulu kwimibhobho, imibhobho engagugulekiyo ye-silicon carbide iye yatshintsha kancinci imibhobho yendabuko. Akufuneki itshintshwe rhoqo emva kweenyanga ezintandathu njengemibhobho eqhelekileyo, kwaye ayifuni iindleko zokulungisa eziphindaphindwayo. Nangona utyalo-mali lokuqala lunokubonakala luphezulu kancinci, lunceda ishishini ukuba longe iindleko ezininzi ekuhambeni kwexesha. Kumashishini afuna imveliso esebenzayo nezinzileyo, ukukhetha imibhobho engagugulekiyo ye-silicon carbide kukukhetha isisombululo sothutho "esingenaxhala kangako, esihlala ixesha elide".
Ngenxa yokwanda kwemfuno yokuqina kwezixhobo kunye nokhuseleko kwimveliso yemizi-mveliso, iimeko zokusetyenziswa kwemibhobho engagugiyo ye-silicon carbide zikhula rhoqo. Isombulula ingxaki "endala nenzima" ekuthuthweni kwemizi-mveliso ngokusebenza okuqinileyo kwezinto ngokwazo, kwaye ikwabonelela amashishini amaninzi ngokhetho oluthembekileyo kwindlela yokunciphisa iindleko kunye nokuphucula ukusebenza kakuhle.
