Kwindawo “yokulwa nobushushu obuphezulu” kwimizi-mveliso yanamhlanje, izinto zesinyithi zemveli zihlala zijongene nemingeni efana nokuthambisa ukuguquguquka, i-oxidation kunye nokugqwala. Kunye nohlobo olutsha lwezinto ezibizwa ngokubai-silicon carbide ceramicngokuzolileyo iba ngumlondolozi oyintloko wezixhobo ezisebenzisa ubushushu obuphezulu ngezakhono zayo ezintathu eziphambili "zokumelana nobushushu obuphezulu, ukulwa nokuvuthuza, kunye nokudluliselwa kobushushu ngokukhawuleza".
1, Amandla okwenyani okumelana namaqondo obushushu aphezulu
Iiceramics ze-silicon carbide ngokwemvelo zinamandla okumelana nobushushu obugqithisileyo. Iiathom zayo ziqhagamshelwe ngokuqinileyo ngeebhondi eziqinileyo ze-covalent, njengenethiwekhi enemilinganiselo emithathu elukiweyo ngeebha zentsimbi, enokugcina ubunzulu besakhiwo nakwiindawo ezinobushushu obuphezulu be-1350 ℃. Olu phawu lwenza kube lula ukusebenza ngobushushu obuphezulu ixesha elide izinto zesinyithi ezingenakumelana nazo, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo kwiindawo ezifana ne-oven lining kunye nokukhuselwa kobushushu beenqwelo-moya.
2, 'Isikhuselo' nxamnye nokugqwala kwe-oxidative
Phantsi koxinzelelo oluphindwe kabini lobushushu obuphezulu kunye nemidiya erhabaxa, izinto eziqhelekileyo zihlala zikrazula umaleko ngokulandelelana njengentsimbi egqwalileyo. Umphezulu we-silicon carbide ceramics unokwenza umaleko okhuselekileyo we-silicon dioxide, njengokuzigquma ngesikrweqe esingabonakaliyo. Olu phawu "lokuziphilisa" luyenza ikwazi ukumelana ne-oxidation yobushushu obuphezulu kwi-1350 ℃ kwaye imelane nokukhukuliseka okuvela kwityuwa enyibilikisiweyo, i-asidi kunye ne-alkali. Igcina ukuma komlindi "okungenamgubo, okungekho kuphalala" kwiindawo ezinzima ezifana nezixhobo zokutshisa inkunkuma kunye neekhemikhali reactors.
3, 'I-courier' yobushushu
Ngokungafaniyo neempawu "ezishushu nezifumileyo" zeeseramikhi eziqhelekileyo, iiseramikhi ze-silicon carbide zinomoya wokushisa ofana nowesinyithi. Zifana nomjelo wokusasaza ubushushu owakhelwe ngaphakathi, onokudlulisela ngokukhawuleza ubushushu obuqokelelweyo ngaphakathi kwesixhobo ngaphandle. Olu phawu "lokungafihli ubushushu" luthintela ngokufanelekileyo umonakalo wezinto ezibangelwa ngamaqondo obushushu aphezulu asekuhlaleni, okwenza izixhobo zobushushu obuphezulu zisebenze ngokukhuselekileyo kwaye zisebenzise amandla amaninzi.
Ukususela kwii-oven zemizi-mveliso ukuya kwii-oven ze-silicon wafer ezishushu ze-photovoltaic, ukusuka kwiityhubhu ezinkulu zemitha ukuya kwii-nozzles ezishushu kakhulu, ii-silicon carbide ceramics ziphinda zibumbe imeko-bume yezobuchwepheshe kwimizi-mveliso eshushu kakhulu ngeenzuzo zazo ezipheleleyo "zokuqina, uzinzo, kunye nokudluliselwa ngokukhawuleza". Njengomboneleli weenkonzo zetekhnoloji obandakanyeka kakhulu kwicandelo le-ceramics eziphambili, siyaqhubeka nokukhuthaza impumelelo kunye nophuhliso ekusebenzeni kwezinto, sivumela izixhobo ezininzi zoshishino ukuba zigcine imeko yokusebenza "ezolileyo neyomeleleyo" kwiindawo ezixineneyo.
——Sidlula umda wobushushu bezinto, sihamba ngeteknoloji!
