"Kwindawo yokulwa nobushushu obuphezulu" kushishino lwanamhlanje, izinto zentsimbi zemveli zihlala zijongana nemingeni efana nokuthambisa i-deformation, i-oxidation kunye nokubola. Kwaye uhlobo olutsha lwezinto ezibizwa ngokubai-silicon carbide ceramicNgokuzolileyo iba ngumgcini ongundoqo wesixhobo sobushushu obuphezulu kunye nesakhono saso esikhulu esithathu “sokumelana nobushushu obuphezulu, ukuchasa ukuphazamiseka, kunye nokudluliselwa kobushushu okukhawulezayo”.
1, Isakhono sokwenyani sokumelana namaqondo obushushu aphezulu
I-silicon carbide ceramics ngokwendalo inakho ukukwazi ukumelana nobushushu obugqithisileyo. Iiathom zayo ziqhagamshelwe ngokuqinileyo ngeebhondi eziqinileyo eziqinileyo, njengothungelwano olumacala-ntathu olulukiweyo ukusuka kwimivalo yentsimbi, enokugcina imfezeko yolwakhiwo nakwindawo zobushushu obuphezulu obuyi-1350 ℃. Olu phawu lwenza kube lula ukusebenza ixesha elide lobushushu obuphezulu ukuba izinto zetsimbi azikwazi ukumelana, okwenza kube yinto efanelekileyo yokukhetha amasimi afana ne-kiln lining kunye ne-spacecraft yokukhusela i-thermal.
2, 'Ikhaka elikhuselayo' ngokuchasene nokuhlwa kwe-oxidative
Phantsi koxinzelelo olukabini lobushushu obuphezulu kunye nemithombo yeendaba edlayo, izixhobo eziqhelekileyo zihlala zixobula umaleko njengomaleko njengentsimbi erulileyo. Umphezulu we-silicon carbide ceramics unokwenza umaleko oshinyeneyo okhuselayo wesilicon dioxide, njengokuzigquma ngesikrweqe esingabonakaliyo. Olu phawu "lokuziphilisa" luyenza ikwazi ukumelana ne-oxidation yobushushu obuphezulu kwi-1350 ℃ kwaye ixhathise ukhukuliseko olusuka kwityuwa enyibilikisiweyo, iasidi kunye nealkali. Igcina isigxina somgcini "akukho powdering, akukho ukuchithwa" kwiindawo ezinzima ezifana nezitshisi zenkunkuma kunye ne-reactors chemicals.
3, 'Ikhuriya' yobushushu
Ngokungafaniyo neempawu "ezitshisayo nezifumileyo" zeekeramics eziqhelekileyo, iiseramics ze-silicon carbide zine-thermal conductivity efana nesinyithi. Kufana nomjelo wokutshatyalaliswa kobushushu owakhelwe ngaphakathi, onokudlulisela ngokukhawuleza ubushushu obuqokelelweyo ngaphakathi kwesixhobo ukuya ngaphandle. Olu phawu "alufihli ubushushu" luthintela ngokufanelekileyo umonakalo owenziwe ngamaqondo aphezulu asekuhlaleni, okwenza izixhobo zobushushu obuphezulu zisebenze ngokukhuselekileyo kwaye zisebenzise amandla ngakumbi.
Ukusuka kwiziko lokushishina kwimizi-mveliso ukuya kwiziko lokutshisa i-silicon ye-photovoltaic, ukusuka kwiityhubhu ezinkulu zemitha ukuya kwimibhobho yobushushu obuphezulu, iiseramics zesilicon carbide zihlengahlengisa imeko yetekhnoloji yoshishino lobushushu obuphezulu kunye nezibonelelo zazo ezibanzi "zokuhlala, uzinzo, kunye nokuhanjiswa okukhawulezayo". Njengomboneleli wenkonzo yetekhnoloji ebandakanyeka ngokunzulu kwintsimi yeekeramics eziphambili, siyaqhubeka nokukhuthaza ukuphumelela kunye nokuveliswa kwezinto ezintsha ekusebenzeni kwezinto eziphathekayo, ukuvumela izixhobo ezininzi zoshishino ukugcina "ukuzola kunye nokuqulunqwa" kwemeko yokusebenza kwiimeko ezinzima.
——Ukophula umda wobushushu bezinto eziphathekayo, sihamba ngeteknoloji!
