Platinum-rhodium hlau yog platinum-raws li rhodium-muaj binary alloy, uas yog cov khoom siv txuas ntxiv ntawm qhov kub thiab txias.Rhodium tsub kom lub thermoelectric muaj peev xwm, oxidation kuj thiab acid corrosion kuj ntawm cov alloy rau platinum.Muaj cov alloys xws li PtRh5, PtRhl0, PtRhl3, PtRh30 thiab PtRh40.Alloys nrog ntau tshaj 20% Rh yog insoluble hauv aqua regia.Feem ntau siv los ua cov ntaub ntawv thermocouple, suav nrog PtRhl0 / Pt, PtRh13 / Pt, thiab lwm yam, siv los ua cov xov hlau thermocouple hauv cov thermocouples, ncaj qha los ntsuas lossis tswj cov kua dej, chav dej thiab cov pa roj hauv qhov ntau ntawm 0-1800 ℃ hauv ntau cov txheej txheem kub ntawm nruab nrab. thiab khoom nto.
Qhov zoo: Platinum rhodium hlau muaj qhov zoo ntawm qhov raug siab tshaj plaws, kev ruaj ntseg zoo tshaj plaws, qhov ntsuas kub ntawm qhov dav, kev pab lub neej ntev thiab kev ntsuas kub siab siab hauv cov thermocouple series.Nws yog tsim rau oxidizing thiab inert atmospheres, thiab tseem tuaj yeem siv rau hauv lub tshuab nqus tsev rau lub sijhawm luv luv, tab sis nws tsis tsim nyog rau kev txo cov huab cua los yog cov cua uas muaj hlau lossis cov hlau tsis muaj vapors..
Cov thermocouples muaj xws li platinum-rhodium hlau B hom, S hom, R hom, platinum-rhodium thermocouple, tseem hu ua high-temperature precious hlau thermocouple, platinum-rhodium muaj tib platinum-rhodium (platinum-rhodium 10-platinum-rhodium) thiab ob lub platinum-rhodium (platinum-rhodium).Rhodium 30-Platinum Rhodium 6), lawv tau siv los ua qhov ntsuas kub ntsuas, feem ntau yog siv nrog cov khoom siv hluav taws xob kub, cov tswj hwm thiab cov khoom siv los tsim cov txheej txheem tswj kev ntsuas ncaj qha lossis tswj 0- Kub xws li kua, vapors thiab gaseous media. thiab cov khoom siv nyob rau hauv thaj tsam ntawm 1800 ° C.
Cov kev lag luam siv yog: hlau, hluav taws xob tsim, roj av, tshuaj lom neeg kev lag luam, iav fiber ntau, zaub mov, iav, tshuaj, ceramics, non-ferrous hlau, tshav kub kho, aerospace, hmoov metallurgy, carbon, coking, luam ntawv thiab dyeing thiab lwm yam yuav luag tag nrho cov. kev lag luam.
