Kwimizi-mveliso emininzi, eminye imibhobho inyamezela iimeko zokusebenza ezinzima ngokuthula: ubushushu obuphezulu, ukugqwala okunamandla, kunye nokuguguleka okuphezulu. 'Yimithambo yegazi yemizi-mveliso' eqinisekisa ukuveliswa okuqhubekayo nokuzinzileyo. Namhlanje siza kuthetha ngaloo ibalaseleyo kolu hlobo lombhobho –umbhobho we-ceramic we-silicon carbide.
Abantu abaninzi bacinga "ngokubhitya" xa besiva "i-ceramic". Kodwa ii-ceramics ze-silicon carbide zemizi-mveliso zilandela "ubulukhuni" kunye "nozinzo". Ubulukhuni bayo buphezulu kakhulu, kwaye ukumelana kwayo nokuguguleka kudlula kakhulu okokwesinyithi kunye nerabha. Iyakwazi ukumelana nokukhukuliseka kolwelo olukhawulezayo oluqulethe amasuntswana aqinileyo ixesha elide; Iimpawu zeekhemikhali zizinzile kakhulu kwaye zinokumelana nokukhukuliseka kwee-asidi ezahlukeneyo ezinamandla, iziseko ezinamandla, kunye neetyuwa; Kwangaxeshanye, inokusebenza ngokuzinzileyo kumaqondo obushushu aphezulu kwaye imelane namaqondo obushushu afikelela kwi-1350 ℃. Ukongeza, inomoya ofanelekileyo wokushisa kunye nomphezulu ogudileyo, onceda ukunciphisa ukumelana nokuhamba kunye nokusetyenziswa kwamandla.
Ngamafutshane, iityhubhu ze-silicon carbide ceramic zenzelwe ukusombulula iingxaki zothutho "ezishushu, ezirhabaxa, nezibolayo". Ekuthuthweni kwe-slag kunye nodaka kumashishini afana nemigodi, i-metallurgy, kunye namandla obushushu, kunokwandisa ubomi benkonzo yemibhobho kwaye kunciphise ixesha lokungasebenzi lokutshintshwa; Ekuthuthweni kweendaba ezibolayo kumashishini okukhusela iikhemikhali kunye nokusingqongileyo, kunokuqinisekisa ukusebenza okuzinzileyo kwexesha elide kunye nokunciphisa umngcipheko wokuvuza. Nangona utyalo-mali lokuqala lunokuba phezulu, iingenelo zexesha elide zibalulekile kwimbono epheleleyo yokunciphisa ukugcinwa, ukunciphisa ukusetyenziswa kwamandla, kunye nokuqinisekisa imveliso.
Ukwenziwa kweetyhubhu ze-silicon carbide ceramic ngumsebenzi onzima. Ngokwesiqhelo, umgubo we-silicon carbide uxutywa nenani elincinci lezongezo ukwenza "umzimba oluhlaza" onamandla athile, uze emva koko utshiswe kubushushu obuphezulu ukuze izinto zibe lukhuni kwaye zibe lukhuni. Ngokweemfuno ezahlukeneyo, iinkqubo ezahlukeneyo ezifana nokutshiza okubangelwa kukusabela kunye nokutshiza okungenaxinzelelo ziya kusetyenziswa. Ukuze kube lula ukufakela, iipayipi ezigqityiweyo zihlala zixhotyiswe ngezinto ezidibanisayo ezifana nee-flanges zesinyithi.
Nangona isebenza kakuhle kakhulu, iityhubhu ze-silicon carbide ceramic zisezizixhobo ze-ceramic ezifuna "unyango oluthambileyo" xa zisetyenziswa. Ukufakwa kunye nokuthuthwa kufuneka kuphathwe ngononophelo ukuze kuthintelwe impembelelo enzima; Qinisekisa inkxaso eyaneleyo kunye nokulungiswa kobushushu ukuze kuthintelwe imithwalo eyongezelelweyo ebangelwa luxinzelelo lwangaphandle okanye utshintsho lobushushu; Ngaphambi kokukhetha izixhobo, kungcono ukuba nonjineli oqeqeshiweyo ahlole indlela ethile yokusetyenziswa, ubushushu, kunye noxinzelelo ukuze afumane isisombululo esifanelekileyo.
Lilonke, iityhubhu ze-ceramic ze-silicon carbide zifikelele kwinqanaba eliphezulu "lokuqina" kunye "nozinzo", zibonelela ngezisombululo ezinokuthenjwa kwiimeko zokuhambisa ezifuna kakhulu, kwaye ngokwenene "ziiqhawe ezingabonakaliyo".
