Mu ntchito zamafakitale zotentha kwambiri, kuyeza kutentha molondola komanso kodalirika ndiye maziko a kuwongolera khalidwe la zinthu, chitetezo cha ntchito, komanso kugwiritsa ntchito bwino mphamvu.Machubu oteteza thermocouple a silicon carbide (NB SiC) okhala ndi nitride-bondedImakhala yodziwika bwino ngati yankho labwino kwambiri, pogwiritsa ntchito ubwino wa silicon nitride ndi silicon carbide kuti ipambane m'malo ovuta kwambiri. Kupatula magwiridwe antchito awo abwino kwambiri, luso lathu losintha zinthu limaonetsetsa kuti limagwirizana bwino ndi mafakitale osiyanasiyana, zomwe zimapangitsa kuti likhale chisankho chabwino kwambiri kwa opanga padziko lonse lapansi.
Kugwiritsa ntchito machubu oteteza a NB SiC thermocouple kumakhudza mafakitale ambiri omwe amafunidwa kwambiri, chifukwa cha makhalidwe awo abwino kwambiri—kukhazikika kutentha mpaka 1500°C, kukana kutentha kwambiri, komanso kukana dzimbiri mwamphamvu. Mu kukonza zitsulo zopanda chitsulo, ndizofunikira kwambiri poyesa kutentha mu uvuni wosungunuka wa aluminiyamu, zinc, mkuwa, ndi magnesium. Mosiyana ndi zipangizo zachikhalidwe, NB SiC siipitsa zitsulo zosungunuka, kuonetsetsa kuti zinthu zomaliza zimakhala zoyera komanso zimakhala zokhazikika kwa nthawi yayitali. Kwa makampani opanga zitsulo ndi zitsulo, machubu awa amagwira ntchito modalirika mu uvuni wophulika ndi njira zotenthetsera zotentha, kupirira kusweka ndi fumbi lamphamvu komanso scoria.
Magawo a petrochemical ndi mankhwala amapindula kwambiri ndi kusakhala ndi mphamvu kwa mankhwala, komwe kumalimbana ndi kukokoloka kwa ma asidi amphamvu, ma alkali, ndi mpweya woopsa m'ma gasifiers a malasha ndi m'mitsempha yoyatsira. Amagwiranso ntchito bwino kwambiri m'mafakitale ndi m'malo otenthetsera zinthu zomwe zimatayidwa kukhala mphamvu, zomwe zimakhala ndi mpweya wotentha kwambiri wokhala ndi sulfure ndi ma chloride. Kuphatikiza apo, m'mafakitale a ceramic, magalasi, ndi kutentha, kuchuluka kwawo kotsika kwa kutentha (4.7×10⁻⁶/°C pa 1200°C) kumathandiza kuti ntchito ikhale yokhazikika panthawi yotenthetsera mwachangu komanso yozizira, kuonetsetsa kuti kutentha kumawerengedwa molondola.
Machubu athu oteteza a NB SiC thermocouple amapereka zosintha zonse kuti akwaniritse zofunikira zapadera za polojekitiyi. Ponena za miyeso, timapereka ma diameter akunja osinthasintha (8mm mpaka 50mm) ndi ma diameter amkati (8mm mpaka 26mm), okhala ndi kutalika kosinthika mpaka 1500mm kapena kupitirira kutengera zojambula. Kusintha kwa kapangidwe kake kumaphatikizapo kuumba kwa blind-end kokhala ndi chidutswa chimodzi kuti kukhale kolimba komanso njira zosiyanasiyana zoyikira—monga ulusi wa M12×1.5 kapena M20×1.5, ma flange okhazikika kapena osunthika, ndi mapangidwe okhala ndi mipata—kuti agwirizane bwino ndi zida zomwe zilipo.
Kapangidwe ka zinthu kangasinthidwenso, ndi kuchuluka kwa SiC kuyambira 60% mpaka 80% ndi kuchuluka kwa Si₃N₄ kuyambira 20% mpaka 40%, kulinganiza magwiridwe antchito ndi mtengo wake malinga ndi dzimbiri kapena kutentha komwe kukufunika. Timaperekanso chithandizo cha pamwamba kuti tichepetse kupendekeka kwa nthaka (mpaka <1% kupendekeka kwa nthaka) ndikuwonjezera kukana dzimbiri, komanso ma phukusi apadera oyendera mtunda wautali. Mothandizidwa ndi kuwongolera bwino khalidwe komanso kutumiza mwachangu (kutumiza kwadzidzidzi kwa maola 48 kulipo), timaonetsetsa kuti magwiridwe antchito nthawi zonse komanso kupezeka kwa zinthu panthawi yake.
Sankhani machubu oteteza kutentha a silicon carbide okhala ndi nitride-bonded kuti muyeze kutentha kodalirika m'malo ovuta. Katswiri wathu wosintha zinthu amatsimikizira kuti zikugwirizana bwino ndi zosowa zanu zamakampani, kuchepetsa ndalama zokonzera ndi nthawi yopuma. Lumikizanani nafe lero kuti mukambirane zomwe mukufuna ndikupeza yankho loyenera.
