Intambo ye-Tungsten: Isetshenziselwa ukwenza ama-thermocouples e-tungsten-rhodium namakhanda ahlanganiswe ngokushesha, izintambo eziboshwe ngesafire, nama-electrode amalaser amakhulu.Ibuye isetshenziselwe ukwenza ama-filaments aphezulu kanye nama-tube cathodes.Ngo-2005, i-multi-purpose tungsten-rhenium alloy wire eyakhiwe inkampani yethu yafakwa ohlwini njengomkhiqizo omusha kazwelonke obalulekile nguMnyango Wezesayensi Nobuchwepheshe.
Intambo ye-Tungsten-rhenium thermocouple inephuzu lokuncibilika elingu-3120-3360 °C futhi ingasetshenziswa kufika ku-3000 °C.Iyi-thermocouple yensimbi engazweli kakhulu.Inezinzuzo zobudlelwano obuhle bomugqa phakathi kwezinga lokushisa namandla e-electromotive, ukuzinza okuthembekile okushisayo kanye nentengo ephansi.Ifaniswe nethuluzi lokubonisa.Izinga lokushisa elingalinganiswa ngokuqondile njengamanje likalwa ezingeni lokushisa elingaphezu kuka-1600 °C.Indlela yokungathintani ivame ukusetshenziswa.Nokho, iphutha lale ndlela likhulu.Isibonelo, izinga lokushisa lokuxhumana lingalinganisa ngokunembile izinga lokushisa langempela.Emazingeni okushisa aphezulu, ama-thermocouples ensimbi ayigugu (i-platinum-rhodium thermocouples) ayabiza futhi izinga lokushisa eliphakeme lingaba ngaphansi kuka-1800 °C kuphela, kuyilapho ama-thermocouples e-tungsten-rhodium engenawo umkhawulo wokushisa okuphezulu kodwa futhi nokuzinza okuhle, ngakho-ke, i-tungsten- I-rhodium thermocouples Isetshenziswa kakhulu kwezensimbi, izinto zokwakha, i-aerospace, izindiza kanye nezimboni zamandla enuzi.Ukushisa kwayo okuphezulu kokusebenza kungafinyelela ku-2800 ° C, kodwa ngaphezu kuka-2300 ° C, idatha iyahlakazeka.I-Tungsten-rhenium thermocouples nayo i-oxidizable kakhulu, ngakho-ke ingasetshenziswa endaweni engenalutho, yokunciphisa, noma emkhathini ongenayo emazingeni okushisa asukela ku-0 kuya ku-2300 °C.Imibhangqwana ye-Tungsten bismuth enamashubhu okuvikela akhethekile nayo ingasetshenziswa isikhathi eside endaweni ene-oxidizing ku-1600 ° C. Ishibhile kunama-thermocouples e-platinum-rhodium futhi ayikwazi ukusetshenziswa emkhathini oqukethe i-carbon (njengasemoyeni equkethe i-hydrocarbon, amazinga okushisa angaphezu kuka-1200 ° C angaphansi kokugqwala).I-Tungsten noma i-tungsten ruthenium ijwayele ukwenza ama-carbides azinzile endaweni ene-carbon, ukuze ukuzwela kwayo kwehliswe futhi kubangele ukuphuka kwe-brittle, futhi phambi kwe-hydrogen, i-carbonization iyashesha.Le nkampani igxile ekukhiqizeni i-anti-oxidation tungsten-rhodium thermocouples.Izinga lokushisa elifanele lingu-0-1500 °C.Isakhiwo sinesendlalelo esikabili noma isendlalelo ezintathu (esingavamile ukusetshenziswa) ishubhu lokuvikela.Ishubhu yokuvikela yangaphandle yesakhiwo seshubhu yokuvikela kabili iyishubhu ye-corundum ehlanzekile.Ishubhu yokuvikela yangaphakathi iyishubhu le-molybdenum silicide, kanti ishubhu lokuvikela langaphandle lemikhono emithathu liyishubhu le-silicon carbide eliphinde lakhiwe kabusha noma ishubhu elikhethekile le-corundum elihlanzekile, ishubhu eliphakathi nendawo kanye neshubhu lokuvikela langaphakathi kuyafana nohlobo lweshubhu eliphindwe kabili, futhi impahla yokugcwalisa ishubhu iyimpahla yokushisa ephezulu yokushisa (ingase isetshenziswe isikhathi eside ngaphansi kwe-1800 ° C), ukuvala i-vacuum nokuvala uphawu olubandayo (i-adhesive yokuvala ingasetshenziswa emazingeni okushisa angaphansi kuka-300 ° C isikhathi eside) ukuqinisekisa ukuthi akukho i-oxygen esele ku-tube.Lo mkhiqizo ulungele ukusetshenziswa ku-vacuum, ukunciphisa kanye namanye amagesi angasebenzi (0~1650 °C) Isilinganiso sokushisa esifanelekile emkhathini we-oxidizing ngu-0 kuya ku-1500 °C.Isikhathi esifanayo: ≥180 s
