I-Tungsten wire: Isetyenziselwa ukwenza i-thermocouples ye-tungsten-rhodium kunye neentloko ezidityanisiweyo ngokukhawuleza, iingcingo eziboshwe ngesafire, kunye nee-electrode zeelaser ezinkulu.Ikwasetyenziselwa ukwenza i-filaments ephezulu kunye ne-tube cathodes.Ngo-2005, i-multi-purpose tungsten-rhenium alloy wire ephuhliswe yinkampani yethu yadweliswa njengemveliso entsha engundoqo yelizwe nguMphathiswa wezeNzululwazi noBuchwepheshe.
I-Tungsten-rhenium thermocouple wire inendawo yokunyibilika eyi-3120-3360 °C kwaye ingasetyenziswa ukuya kuthi ga kwi-3000 °C.Yeyona thermocouple yentsimbi exhathisayo.Ineenzuzo zobudlelwane obuhle bomgca phakathi kobushushu kunye namandla e-electromotive, ukuzinza okuthembekileyo kwe-thermal kunye nexabiso eliphantsi.Ihambelana nesixhobo sokubonisa.Ubushushu obunokulinganiswa ngokuthe ngqo okwangoku bulinganiswa kubushushu obungaphezulu kwe-1600 °C.Indlela yokungaqhagamshelwa isoloko isetyenziswa.Nangona kunjalo, impazamo yale ndlela inkulu.Umzekelo, iqondo lokushisa loqhagamshelwano linokulinganisa ngokuchanekileyo ubushushu bokwenyani.Kwii-thermocouples zobushushu obuphezulu, i-thermocouples yentsimbi exabisekileyo (i-platinum-rhodium thermocouples) iyabiza kwaye ubushushu obuphezulu bunokuba ngaphantsi kwe-1800 °C kuphela, ngelixa i-thermocouples ye-tungsten-rhodium ayinayo kuphela umda ophezulu wokushisa kodwa kunye nokuzinza okulungileyo, ngoko ke, i-tungsten- I-rhodium thermocouples Isetyenziswa kakhulu kwisinyithi, izixhobo zokwakha, i-aerospace, inqwelomoya kunye namashishini amandla enyukliya.Iqondo lokushisa eliphezulu lokusebenza lingafikelela kwi-2800 ° C, kodwa ngaphezu kwe-2300 ° C, idatha iyahlakazeka.I-Tungsten-rhenium thermocouples nayo i-oxidizable kakhulu, ngoko ke ingasetyenziswa kwi-vacuum, ukunciphisa, okanye umoya ongasebenziyo kumaqondo obushushu ukusuka kwi-0 ukuya kwi-2300 °C.Izibini ze-Tungsten bismuth ezineetyhubhu ezikhethekileyo zokukhusela zingasetyenziselwa ixesha elide kwi-oxidizing atmosphere kwi-1600 ° C. Zingabizi kakhulu kune-platinum-rhodium thermocouples kwaye azikwazi ukusetyenziswa kwi-carbon-containing atmospheres (ezifana ne-hydrocarbon-containing atmospheres; amaqondo obushushu angaphezu kwe-1200 ° C aphantsi kokuhlwa).I-Tungsten okanye i-tungsten ruthenium ijwayele ukwenza i-carbides ezinzile kwi-carbon-containing atmosphere, ukwenzela ukuba uvakalelo lwayo luthotywe kwaye i-brittle fracture ibangelwa, kwaye phambi kwe-hydrogen, i-carbonization ikhawuleza.Inkampani igxile kwimveliso ye-anti-oxidation tungsten-rhodium thermocouples.Olona luhlu lobushushu luyi-0-1500 °C.Isakhiwo si-double-layer okanye i-three-layer (engasetyenziswanga ngokuqhelekileyo) ityhubhu yokukhusela.Ityhubhu yokukhusela yangaphandle yesakhiwo setyhubhu yokukhusela i-tube yi-ultra-pure corundum tube.Umbhobho wokukhusela wangaphakathi ngumbhobho we-molybdenum silicide, kunye netyhubhu yokukhusela yangaphandle ye-sleeve emithathu yityhubhu ye-silicon carbide ehlaziyiweyo okanye ityhubhu ekhethekileyo ye-corundum ecocekileyo, ityhubhu ephakathi kunye netyhubhu yokukhusela yangaphakathi iyafana nohlobo lwetyhubhu ephindwe kabini, kwaye into yokuzalisa ityhubhu yinto ephezulu yokushisa ukushisa (inokuba ukusetyenziswa kwexesha elide ngaphantsi kwe-1800 ° C), ukutywinwa kwe-vacuum kunye nokutywinwa kwesiphelo esibandayo (i-adhesive yokutywina ingasetyenziselwa kumaqondo okushisa angaphantsi kwe-300 ° C ixesha elide) ukuqinisekisa ukuba akukho. ioksijini eseleyo kwityhubhu.Le mveliso ilungele ukusetyenziswa kwi-vacuum, ukunciphisa kunye nezinye iigesi ze-inert (0 ~ 1650 °C) Umlinganiselo ofanelekileyo weqondo lokushisa kwi-oxidizing atmosphere yi-0 ukuya kwi-1500 °C.Ixesha elizinzileyo: ≥180 s
