Kwiinkqubo zoshishino ezisebenzisa ubushushu obuphezulu, ukulinganisa ubushushu ngokuchanekileyo nangokuthembekileyo yeyona nto ibalulekileyo ekulawuleni umgangatho wemveliso, ukhuseleko lokusebenza, kunye nokusebenza kakuhle kwamandla.Iityhubhu zokukhusela i-thermocouple ze-silicon carbide (NB SiC) ezibotshelelwe yi-NitrideZibonakala njengesisombululo esibalaseleyo, zisebenzisa izibonelelo ezisebenzisanayo ze-silicon nitride kunye ne-silicon carbide ukuze ziphumelele kwiindawo ezinzima. Ngaphandle kokusebenza kwazo okugqwesileyo, amandla ethu okwenza ngokwezifiso aqinisekisa ukuba zidityaniswa ngokungenamthungo kunye nezicwangciso ezahlukeneyo zoshishino, nto leyo ezenza zibe lolona khetho lukhethwayo kubavelisi behlabathi.
Ukusetyenziswa kweetyhubhu zokukhusela i-NB SiC thermocouple kugubungela amashishini amaninzi afunwa kakhulu, kuqhutywa ziimpawu zazo ezibalaseleyo—ukuzinza kobushushu obuphezulu ukuya kuthi ga kwi-1500°C, ukumelana okuhle kakhulu nokutsha kobushushu, kunye nokumelana okunamandla kokugqwala. Kwinkqubo yesinyithi engenasinyithi, ziyimfuneko ekulinganisweni kobushushu kwiifutha zokunyibilikisa i-aluminium, i-zinc, i-copper, kunye ne-magnesium. Ngokungafaniyo nezixhobo zemveli, i-NB SiC ayingcolisi iintsimbi ezinyibilikisiweyo, iqinisekisa ubunyulu beemveliso zokugqibela ngelixa igcina uzinzo lwexesha elide. Kwishishini lesinyithi kunye ne-metallurgical, ezi tyhubhu zisebenza ngokuthembekileyo kwiifutha zokuqhumisa kunye neenkqubo zokuqengqeleka ezishushu, zimelana nokukrala okuvela kuthuli olunesantya esiphezulu kunye ne-scoria.
Amacandelo e-petrochemical kunye neekhemikhali azuza kakhulu kukungasebenzi kakuhle kweekhemikhali, okumelana nokukhukuliseka yi-asidi enamandla, ii-alkalis, kunye neegesi ezinobuthi kwi-gesiifiers zamalahle kunye nee-reaction vessels. Asebenza kakuhle kakhulu kwizityalo ezisebenzisa inkunkuma ukuya kumandla kunye nee-incinerators, ezihlala ixesha elide kwiindawo ezinzima zegesi yolwelo olushushu oluphezulu oluqulethe i-sulfur kunye ne-chloride. Ukongeza, kumashishini e-ceramic, iglasi, kunye nonyango lobushushu, i-coefficient yabo yokwandiswa kobushushu obuphantsi (4.7×10⁻⁶/°C kwi-1200°C) ivumela ukusebenza okuzinzileyo ngexesha lemijikelo yokufudumeza nokupholisa ngokukhawuleza, ukuqinisekisa ukufundwa kobushushu okuchanekileyo.
Iityhubhu zethu zokukhusela i-thermocouple ze-NB SiC zibonelela ngokwezifiso ezibanzi ukuhlangabezana neemfuno zeprojekthi ezizodwa. Ngokuphathelele ubukhulu, sibonelela ngeedayamitha zangaphandle eziguquguqukayo (8mm ukuya kwi-50mm) kunye needayamitha zangaphakathi (8mm ukuya kwi-26mm), ubude obunokulungiselelwa ukuya kuthi ga kwi-1500mm okanye nangaphezulu ngokusekelwe kwimizobo. Ukulungiswa kwesakhiwo kubandakanya ukubumba okungabonakaliyo kwento enye ukuze kuphuculwe ukuqina kunye neendlela ezahlukeneyo zokufakela—ezifana nemisonto ye-M12×1.5 okanye i-M20×1.5, iiflanges ezizinzileyo okanye ezishukumayo, kunye noyilo olunemiqolo—ukuze zivumelane kakuhle nezixhobo ezikhoyo.
Ulwakhiwo lwezinto lunokulungiswa, kunye nomxholo weSiC oqala kwi-60% ukuya kwi-80% kunye nomxholo weSi₃N₄ ukusuka kwi-20% ukuya kwi-40%, ukulinganisela ukusebenza kunye neendleko zeemfuno ezithile zokugqwala okanye ubushushu. Sikwabonelela ngonyango lomphezulu ukunciphisa ukugqwala (ukuya kuthi ga kwi-<1% ukugqwala komphezulu) kunye nokuphucula ukumelana nokugqwala, kunye nokupakisha okwenziwe ngokwezifiso ukuthuthwa komgama omde. Sixhaswa lulawulo oluqinileyo lomgangatho kunye nokuhanjiswa ngokukhawuleza (ukuthunyelwa okungxamisekileyo kweeyure ezingama-48 kuyafumaneka), siqinisekisa ukusebenza rhoqo kunye nobonelelo ngexesha elifanelekileyo.
Khetha iityhubhu zokukhusela i-thermocouple ze-silicon carbide ezibotshelelwe yi-nitride ukuze zilinganise ubushushu ngendlela ethembekileyo kwiindawo ezinzima. Ubuchule bethu bokwenza ngokwezifiso buqinisekisa ukulingana okufanelekileyo neemfuno zakho zoshishino, kunciphisa iindleko zokulungisa kunye nexesha lokungasebenzi. Nxibelelana nathi namhlanje ukuze uxoxe ngeenkcukacha zakho kwaye ufumane isisombululo esilungiselelwe wena.
