Mumabasa emaindasitiri anodziya zvakanyanya, kuyera tembiricha kwakarurama uye kwakavimbika ndiyo musimboti wekudzora mhando yechigadzirwa, kuchengetedzeka kwekushanda, uye kushanda zvakanaka kwesimba.Machubhu ekudzivirira e thermocouple e silicon carbide (NB SiC) ane nitride-bondedInoonekwa semhinduro yepamusoro, ichishandisa mabhenefiti ekubatana kwesilicon nitride nesilicon carbide kuti ibudirire munzvimbo dzakaoma. Kupfuura mashandiro avo anoshamisa, kugona kwedu kugadzirisa kwakagadzirwa kunoita kuti vabatane zvakanaka nemagadzirirwo akasiyana-siyana emaindasitiri, zvichiita kuti ive sarudzo inofarirwa nevagadziri vepasi rose.
Mashandisirwo emachubhu ekudzivirira eNB SiC thermocouple anowanikwa mumaindasitiri akawanda anodiwa zvakanyanya, zvichikonzerwa nehunyanzvi hwawo hwakanaka—kugadzikana kwekupisa kwakanyanya kusvika 1500°C, kuramba kupisa kwakanyanya, uye kuramba ngura kwakasimba. Mukugadzirisa simbi isina ferrous, akakosha pakuyera tembiricha mumachoto ekunyungudutsa ealuminium, zinc, copper, uye magnesium. Kusiyana nezvinhu zvechinyakare, NB SiC haisvibise simbi dzakanyungudutswa, ichivimbisa kuchena kwezvigadzirwa zvekupedzisira uku ichichengetedza kugadzikana kwenguva refu. Kune indasitiri yesimbi nesimbi, machubhu aya anoshanda zvakavimbika mumachoto anoputika uye maitiro ekuputira anopisa, achitsungirira kukuvadzwa neguruva rine kumhanya kwakanyanya uye scoria.
Makambani epetrochemical nemakemikari anobatsirwa zvikuru nekusashanda zvakanaka kwemakemikari, izvo zvinodzivisa kukurwa kwemvura neacids dzakasimba, alkalis, uye magasi ane chepfu mumagetsi emagetsi emarasha nemidziyo yemagetsi. Anoshandawo zvakanaka mumiti inorasirwa simba uye mumidziyo yekupisa, achigara munzvimbo dzakaoma dzemagasi emvura anodziya ane sarufa nemachloride. Pamusoro pezvo, mumaindasitiri eceramic, magirazi, uye ekupisa, chiyero chavo chekuwedzera kupisa chakaderera (4.7×10⁻⁶/°C pa1200°C) chinoita kuti ishande zvakanaka panguva yekupisa nekukurumidza uye kutonhora, zvichiita kuti tembiricha iverengeke zvakanaka.
Machubhu edu ekudzivirira eNB SiC thermocouple anopa maitiro akazara ekugadzirisa kuti aenderane nezvinodiwa zvepurojekiti zvakasiyana. Panyaya yehukuru, tinopa dhayamita dzekunze dzinochinjika (8mm kusvika 50mm) uye dhayamita dzemukati (8mm kusvika 26mm), nehurefu hunogona kugadziriswa kusvika 1500mm kana kupfuura zvichibva pamifananidzo. Kugadzirisa chimiro kunosanganisira molding yechinhu chimwe chete kuti igare kwenguva refu uye sarudzo dzakasiyana-siyana dzekuisa - dzakadai seM12×1.5 kana M20×1.5 threads, flanges dzakagadzika kana dzinofambiswa, uye magadzirirwo ane groove - kuti zvikwane zvakanaka nemidziyo iripo.
Kuumbwa kwezvinhu kunogonawo kugadziriswa, neSiC iri pakati pe60% kusvika 80% uye Si₃N₄ iri pakati pe20% kusvika 40%, zvichienzanisa mashandiro uye mutengo wezvinhu zvakati wandei zvakaita sengura kana tembiricha. Tinopawo mishonga yekuderedza porosity (kusvika pasi pe1% porosity yeganda) uye kuvandudza kuramba ngura, pamwe nekurongedza kwakagadzirirwa kutakurwa kure. Tichitsigirwa nekudzora kwakasimba kwemhando uye kutumira nekukurumidza (kutumira nekukurumidza kwemaawa makumi mana nemasere kuripo), tinoona kuti mashandiro anoenderana uye kuwanikwa panguva yakakodzera.
Sarudza machubhu ekudzivirira esilicon carbide thermocouple ane nitride-bonded kuti apime tembiricha munzvimbo dzakaoma. Hunyanzvi hwedu hwekugadzirisa zvinhu hunovimbisa kukodzera zvakakwana zvinodiwa neindasitiri yako, zvichideredza mari yekugadzirisa uye nguva yekuzorora. Tibate nhasi kuti ukurukure zvaunoda uye uwane mhinduro yakagadzirirwa iwe.
