Ukuqina okuphezulu kwe-selicon carbide tube

I-SSiC yenye yezona zinto zinzima emhlabeni, okwesibini emva kwedayimani. Ngenxa yobulukhuni bayo, ukuxhathisa kwe-abrasion, kunye neempawu ze-thermal conductivity yenza ukhetho olufanelekileyo lwezinto zokusetyenziswa apho ukuqina kubaluleke kakhulu.

Iityhubhu ze-SSiC zibonelela ngobomi obude obuphezulu kwindawo ezinobushushu obuphezulu kwaye zinokumelana nokubola kweekhemikhali., I-Abrasion, impembelelo kunye nokuxhatshazwa ukusuka ekuvezweni kweekhemikhali. Ukwandiswa kwe-thermal ephantsi kunye namandla anika ukhuseleko ekunyukeni ngokukhawuleza kweqondo lokushisa – ebaluleke kakhulu xa uxhasa i-thermocouples kwiziko lamashishini.

Amandla aphezulu

Ukuqina okugqwesileyo kweSilicon carbide kuyenza ibe yinto efanelekileyo yokusetyenziswa kwemizi-mveliso. Iyakwazi ukumelana namaqondo obushushu aphezulu kunye neekhemikhali ezirhabaxa ngelixa ikwazi ukumelana nokudleka, ukurhawuka kunye nokhukuliseko; Ukwengeza, ukuxinana kwayo kuphikisana nedayimani.

Amandla aphezulu e-SSiC ayenza ibe yinxalenye ebalulekileyo kwizicelo ezininzi ezinje ngee-injini zegesi.. Inokumelana namanqanaba aphezulu ebhayisikile eshushu kwaye yomelele ngexesha lokuLahleka kweNgozi yokuphola. (LOCA) uvavanyo, ngelixa ukwaxhathisa ukuthotywa kwi-asidi ezahlukeneyo kunye nealkali.

Iityhubhu ze-silicon carbide ceramic zihlala zisetyenziselwa ukunyibilikisa isinyithi, ukucocwa kwe-oyile kunye nezicelo zobunjineli be-aerospace. Ukongeza, ezi ityhubhu zinokufunyanwa zisetyenziswa njengeziko lomlilo okanye imilomo yesitshisi kwiziko kunye nezinto zokucima umlilo.; kwimisebenzi yokugaya ioli njengezixhobo zetyhubhu zokukhusela i-thermocouple okanye izitywina; iityhubhu zenkxaso okanye amacandelo etyhubhu yokukhusela i-thermocouple okanye izitywina kwimisebenzi yokomba yeoli – singasathethi ke ngokuba yinxalenye ebalulekileyo yeentlobo ezininzi zeempompo ezisebenza phantsi kweemeko ezinzima.

Ukuxhathisa ubushushu obuphezulu

Iityhubhu ze-silicon ze-carbide zivelele kwiindawo eziphakamileyo zokushisa ngenxa yokuqina kwazo; oku kubenza bakwazi ukumelana nokuthotywa kwemichiza ngelixa begcina imilinganiselo yabo kunye nokumelana noxinzelelo lomatshini nokuba kubushushu obugqithisileyo..

Ukudibanisa ukumelana nomhlwa kunye nokukwazi kwabo ukuthutha imichiza eyonakalisayo okanye ukuhambisa iigesi ezishushu kakhulu phakathi kwezigaba zenkqubo kwenza le mibhobho ilungele amashishini okulungisa imichiza.. Ziye ziqeshwe rhoqo njengemibhobho esetyenziselwa ukuthutha olu manzi okanye iigesi ezishushu kakhulu phakathi kwezigaba; ukongeza badlala indima ebalulekileyo kumashishini okomba ioyile njengoko bekwazi ukunyamezela amaqondo obushushu aphezulu kunye neemeko ezinzima..

I-Thermal conductivity yezinto ze-ceramic nazo zigqwesileyo, oku kuthetha ukuba bafunxa kwaye bachitha amandla ngesantya esikhethekileyo, okukhokelela ekunciphiseni ukusetyenziswa kwamandla kunye nokukhutshwa kwezicelo kwimizi-mveliso – ilungele ukuhlangabezana nokujoliswe kuko okukhulayo kokusingqongileyo. Baye bangqina izinto ezibalulekileyo kwiinjini ze-injini yegesi apho ukusebenza kwabo okuphezulu kukhuthaze inkqubela phambili yetekhnoloji..

Ukunganyangeki kwe-Porrosion

I-Silicon carbide iqhayisa ngeempawu zobunzima obuphezulu, ukuxhathisa okuphantsi kwe-abrasion, ukumelana nobushushu obuphantsi kunye nokumelana nokunyuka kobushushu obuphezulu, ukumelana nokugqwesa okugqwesileyo kunye nokumelana nokothuka kwe-thermal, eyenza ukuba ilungele imveliso ibe yimiqadi, iirola, imibhobho yomoya yokupholisa, imibhobho yokukhusela i-thermocouple, imibhobho yokulinganisa ubushushu, imilomo yezitshisi kunye neendawo ezixhathisayo ezinxitywayo kunye nezahlulo ezahlukeneyo ezinokwakheka okukhethekileyo.

I-Aluminiyam yeyona nto ifanelekileyo kumacandelo oshishino lwamandla afana nezitshisi, imilomo, iivalvu kunye nee-manifolds ekufuneka zimelane nemekobume erhabaxa kunye neekhemikhali, ukubonelela ngogcino lweendleko ezibalulekileyo kubasebenzisi bokuphela ngokuhlala ixesha elide kunye nokusebenza kakuhle kwamandla.

I-Kerui Refractory inikezela ngeetyhubhu ezikhanyayo ze-SiC kwiidayamitha ezahlukeneyo kunye nobude, ezifanelekileyo kwizicelo ezahlukeneyo kwiziko loshishino lwamandla. Ezi zomelele, iityhubhu zegesi ezingenakukhanya zibandakanya ukuhanjiswa okuphezulu kwe-thermal, i-corrosion kunye nokumelana nokunxiba kunye namazinga aphantsi okunyuka kwe-thermal – iimpawu ezifanelekileyo kwiziko loshishino lwamandla.

Ukuchasa okugqwesileyo kweAbrasion

I-silicon carbide (I-SSiC) yenye yezona zinto zinzima zaziwayo, ukuqhayisa ngomlinganiselo wobulukhuni be-Mohs 9. Indibaniselwano yayo yokumelana ne-abrasion kunye ne-inertness yekhemikhali iyenza ilungele iinkqubo zemizi-mveliso ezifana nokunyibilikiswa kwesinyithi, ukwenziwa kwe-semiconductor, ukuveliswa kwamandla, ukusulungekiswa kweoli, ukuveliswa kwephepha kunye nobunjineli be-aerospace. Ngaphezulu, I-SSiC inokumelana namaqondo obushushu aphezulu ngaphandle kokuthotywa ngomothuko wobushushu.

Olu phononongo luvavanye isiphumo sohlobo lomhlaba kwiimpawu zokunxiba ze-nitride-bonded silicon carbide kunye neentsimbi eziqhele ukusetyenziswa ukwenza iindawo ezisebenzayo zomhlaba.. Iziphumo zibonise ukuba i-nitride-bond silicon carbide ibonise ukuxhathisa okuphezulu kwilahleko enkulu xa kuthelekiswa neentsimbi ezivavanyiweyo, ngaphandle kweemeko zomhlaba okhanyayo. Ukuxhathisa kwayo okuphezulu kwimpembelelo yokuguga kunokubalelwa kumlinganiso wayo ophezulu wokukhuhlane ovumela ukuba imelane noxinzelelo lokucheba olusuka kumasuntswana omhlaba., okukhokelela ekuxhathiseni ukunxitywa kwempembelelo ephezulu kwaye ekugqibeleni kufakwe endaweni yentsimbi kwizicelo ezinje nge-tillage kunye nezixhobo zokwakha ezitshintshileyo ngelixa zixhathisa kakhulu ngokuchasene nokuqhekeka okunokonakala..
