Ii-thermocouples zingumqolo wokujonga ubushushu kwiinkqubo ezininzi zoshishino—ukusuka ekunyibilikiseni isinyithi ukuya ekuhlanganisweni kweekhemikhali. Sekunjalo, ukusebenza kwazo kunye nobomi bazo buxhomekeke ngokupheleleyo kwinto enye ebalulekileyo: ityhubhu yokukhusela. Kwiimeko ezinzima zoshishino, iityhubhu zokukhusela ze-thermocouple zemveli (ezenziwe ngesinyithi, i-alumina, okanye i-silicon carbide ecocekileyo) zihlala zisilela ukumelana nobushushu obugqithisileyo, imidiya ebolayo, okanye amasuntswana arhabaxa. Oku kukhokelela ekutshintsheni rhoqo kwe-thermocouple, idatha engachanekanga yobushushu, kunye nexesha elibizayo lokungasebenzi kwemveliso.
Ukuba udiniwe kukubeka emngciphekweni ukuthembeka kwe-thermocouple,Iityhubhu zokukhusela i-Thermocouple zeSilicon Nitride eziBotshelelweyo zeSilicon Carbide (NSiC) zeSilicon Nitridezezona zisombululo zitshintsha umdlalo ozifunayo.

Kutheni iSilicon Nitride Bonded Silicon Carbide iBalasele ekuKhuselweni kweThermocouple
Iityhubhu zokukhusela i-thermocouple zifuna ulungelelwaniso olukhethekileyo lweempawu: ukumelana nobushushu, ukumelana nokugqwala, amandla oomatshini, kunye nokuqhuba kobushushu. I-NSiC igqwesile kuzo zonke ezi ndawo, iphumelela ngaphezu kwezixhobo zemveli kuzo zonke iindlela eziphambili zokulinganisa:
1. Ukumelana nobushushu obugqithisileyo ukuze kubonakale ngokungaphazanyiswa
Ii-thermocouples kumashishini afana nokuvelisa iglasi okanye i-metal casting zisebenza kumaqondo obushushu angaphezulu kwe-1,500°C. Iityhubhu zokukhusela ii-thermocouple ze-NSiC zisingatha oku ngokulula—zinobushushu obuqhubekayo bokusebenza obufikelela kwi-1,600°C (2,912°F) kunye nokumelana kwexesha elifutshane kwi-1,700°C (3,092°F). Ngokungafaniyo neetyhubhu zesinyithi ezinyibilikisa okanye ezinyibilikisayo, okanye iityhubhu ze-alumina eziqhekekayo phantsi koxinzelelo lobushushu, i-NSiC igcina ulungelelwaniso lwesakhiwo nokuba ngexesha lokutshintsha kobushushu ngokukhawuleza. Oku kuthetha ukuba i-thermocouple yakho ihlala ikhuselekile, kwaye idatha yakho yobushushu ihlala ichanekile—nokuba ubushushu bukhulu kangakanani na.
2. Ukumelana Okuphezulu Kokugqwala Ukukhusela Kwimidiya Enobundlongondlongo
Iinkqubo zoshishino zihlala zibeka ii-thermocouples kwisinyithi esinyibilikisiweyo (i-aluminium, i-zinc, i-copper), izisombululo ze-asidi/i-alkaline, okanye iigesi ezirhabaxa (i-sulfur dioxide, i-chlorine). Ulwakhiwo oluxineneyo lwe-NSiC olune-nitride ludala umqobo ongangeniyo nxamnye nezi zinto. Ngokungafaniyo neetyhubhu ze-silicon carbide ezicocekileyo, ezithambekele ekurhawuzelweni kwiindawo ezimanzi ezinobushushu obuphezulu, ulwakhiwo olulodwa lwe-NSiC luphucula ukumelana ne-oxidation—ukuqinisekisa ukuba i-thermocouple yakho ihlala ikhuselekile ekurhawuzeni kangangeminyaka. Oku kubalulekile kwizicelo ezifana nokucubungula iikhemikhali, ukutshisa inkunkuma, kunye nokuhlanganiswa kwezinto zebhetri.
3. Amandla Oomatshini Angaqhelekanga Okumelana Nokuguguleka Nempembelelo
Ii-thermocouples kwizityalo zesamente, kwizikhululo zamandla, okanye kwizibonelelo zokucubungula izimbiwa zijongene nezisongelo ezingapheliyo: uthuli olurhabaxa, amasuntswana abhabhayo, kunye nefuthe loomatshini. Iityhubhu zokukhusela ii-thermocouple ze-NSiC zakhiwe ukuze zimelane nale mingeni, zinamandla okugoba angaphezu kwe-300 MPa kunye nobunzima beVickers (HV10) obuyi-≥ 1,800. Oku kuzenza zihlale ixesha elide ngokuphindwe kathathu ukuya kahlanu kuneetyhubhu zemveli, okunciphisa isidingo sokutshintshwa rhoqo. Kwimisebenzi yakho, oku kuthetha ukuba ixesha lokungasebenzi lincinci, iindleko zokulungisa ziphantsi, kunye nokusebenza kwe-thermocouple okuthembekileyo ngakumbi.
4. Ukuqhuba Ubushushu Okulungeleyo Ukufundwa Okukhawulezayo Nokuchanekileyo
Ixabiso le-thermocouple lixhomekeke kubuchule bayo bokuphendula ngokukhawuleza kutshintsho lobushushu. Ukuqhuba kobushushu be-NSiC (60–80 W/(m·K)) kuphezulu kakhulu kune-alumina okanye iityhubhu zesinyithi, okuvumela ukudluliselwa kobushushu ngokukhawuleza ukusuka kwinkqubo ukuya kwi-thermocouple junction. Oku kuqinisekisa ukuba i-thermocouple yakho inika idatha echanekileyo nechanekileyo ngexesha langempela—ebalulekileyo ekugcineni ulawulo lwenkqubo kunye nomgangatho wemveliso. Ukongeza, i-NSiC’s low thermal expansion coefficient (3.5–4.5 × 10⁻⁶/°C) inciphisa uxinzelelo lobushushu, ithintela iintanda ezinokuphazamisa ukuchaneka kokulinganisa.
5. Ixesha Elide Elifanelekileyo Kwiindleko Eziphantsi Zobunini Bendlu
Nangona iityhubhu zokukhusela i-thermocouple ze-NSiC zinokuba notyalo-mali oluphezulu lokuqala kuneendlela zemveli, ubomi bazo obude benkonzo (iminyaka emi-2-5 kwiimeko ezinzima) kunye neemfuno ezincinci zolondolozo zibonelela ngokonga okukhulu kwexesha elide. Ngokunciphisa ukuphindaphinda kwe-thermocouple kunye nexesha lokungasebenzi kwemveliso, i-NSiC yehlisa iindleko zakho zizonke zobunini (TCO) kwaye yonyusa imbuyekezo yakho kutyalo-mali (ROI). Kwizityalo zoshishino ezifuna ukuphucula ukusebenza kakuhle, olu lukhetho olukrelekrele nolungenabungozi kwixesha elizayo.
