Kwiikona zeendibano zocweyo zefektri kunye nokuthutha imigodi, kukho "indima" ebalulekileyo kodwa enganakwa ngokulula - umbhobho wokuhambisa. Bathutha iiminerali, udaka, kunye nezixhobo zemichiza ekrwada imihla ngemihla, kwaye iindonga zabo zangaphakathi zihlala ziphantsi koxinzelelo kunye nokuchaphazeleka kwemathiriyeli. Ngokuhamba kwexesha, bathambekele ekunxibeni kunye nokukrazula, ukuvuza, okungachaphazeli nje imveliso kodwa kufuna ukugcinwa okubizayo kunye nokutshintshwa. Umbhobho we-silicon carbide okwaziyo ukumelana nokunxitywa esiza kuthetha ngawo namhlanje ufana nokubeka umaleko “wesikrweqe sentsimbi esingabonakaliyo” kwimibhobho eqhelekileyo, ukusombulula ngokuzolileyo le ngxaki inkulu.
Omnye unokubuza, yintoni nai-silicon carbide? Enyanisweni, asiyomfihlelo. Ngokusisiseko, yimathiriyeli eyenziweyo eyenziwe ngekhabhoni kunye nesilicon, enobunzima besibini kuphela kwidayimane.
Xa kuthelekiswa nodonga lwangaphakathi lwemibhobho eqhelekileyo, ubulukhuni be-silicon carbide lining buphindwe kaninzi ngaphezulu. Xa amasuntswana e-ore abukhali kunye nodaka oluhamba ngesantya esiphezulu luhlamba eludongeni lwangaphakathi, i-silicon carbide inokusebenza njengekhaka lokuthintela ukukhuhlana kunye nokuthintela imikrwelo okanye izibonda ukuba zenzeke ngokulula. Nokuba ukuthuthwa kwexesha elide kwezinto zokugqoka okuphezulu, udonga lwayo lwangaphakathi lunokuhlala luthe tyaba kwaye lugudileyo, ngaphandle kokuba lube lukhuni okanye lube lukhuni ngenxa yokuguga, lwandisa kakhulu ubomi benkonzo yombhobho.
Ukongeza kwinkcaso yokunxiba, ikwanesakhono esifihlakeleyo – 'inokumelana nolwakhiwo'. Kwimveliso yemizi-mveliso, izinto ezihanjiswayo azihlali nje “zisemhlabeni”, kodwa zinokuthwala amaqondo obushushu aphezulu kunye ne-acid-base corrosion. Ngokomzekelo, kwintsimi yobunjineli bemichiza, ezinye izinto zinokonakala okuqinileyo, yaye ulwabuko lwemibhobho eqhelekileyo luvuthuluka lula yaye luxotyulwe; Kwishishini le-metallurgical, izinto eziphezulu zokushisa zingabangela i-deformation kunye nokungaphumeleli kwe-lining. I-silicon carbide lining inokumelana namaqondo obushushu angamakhulu aliqela degrees Celsius kwaye ixhathise ukhukuliseko lwemithombo yeendaba eneasidi kunye nealkaline, igcina ukusebenza okuzinzileyo kuyo nayiphi na "imekobume erhabaxa".
Kumashishini, izibonelelo eziziswa ngolu luhlu luncinci lubonakala kakhulu: akukho mfuneko yokuvala rhoqo kunye nokutshintsha imibhobho, ukunciphisa ilahleko ebangelwa ukuphazamiseka kwemveliso; Akukho mfuneko yokutyalomali ngokuphindaphindiweyo kwiindleko zokugcinwa, kunokugcina imali eninzi ngexesha elide; Okubaluleke ngakumbi, inokuqinisekisa ukuthuthwa kwezinto eziphathekayo kwaye iphephe iingozi zokhuseleko kunye neengxaki zokusingqongileyo ezibangelwa ukuvuza kwemibhobho.
Ukusuka kwizifakelo zemibhobho ezingaqondakaliyo ukuya “kwisixhobo esinganxibiyo” esikhusela imveliso yemizi-mveliso, ixabiso le-silicon carbide ekwaziyo ukumelana nemibhobho lisekukwazini kwayo “ukusombulula iingxaki ezinkulu kwiinkcukacha ezincinci”. Kumashishini aqhuba imveliso esebenzayo kwaye ezinzileyo, ukukhetha akukona nje ukuphuculwa kwezixhobo, kodwa kunye nokuqwalaselwa kwexesha elide lokuphumelela kwemveliso kunye nokulawulwa kweendleko.
