Yuav ua li cas kom huv si platinum-rhodium thermocouples?

Raws li ib txwm thermocouple, platinum-Rhodium thermocouple tau maj mam siv dav hlau {}}} Tab sis tib lub sijhawm tswj nws thaum siv! Tus editor qhia cov lus qhia txij nkawm ntawm platinum-rhodium thermoco thermocouples los ntawm kev sau cov ntaub ntawv.
1) pickling

Siv cov oxidizing muaj peev xwm ntawm cov kua qaub kom tshem tawm cov organic thiab lwm yam immolves uas tuaj yeem ua kom muaj qhov kub ntawm cov kua qaub rau cov roj ntsha uas muaj txiaj ntsig-rhodium thermoco thermocouples.

Muab cov khoom siv hluav taws xob kub kom zoo rau hauv lub voj voos nrog li 80 teev tsaus ntuj, thiab muab tso rau hauv 30 hli Acid . Lub hom phiaj ntawm pickling yog kom huv qee cov organic thiab oxides ntawm cov npoo hluav taws xob.

2) Sodium Borate Tu

Cov siv high-kub muaj nuj nqis hlau platinum-Rhodium thermocouple Boric acid daws teeb meem raws cov electrode {}}}}}} Lub taub hau ntawm socketly borate tshem tawm yog feem ntau kom tshem cov hlau thiab oxides uas yog insoluble hauv hydrochloric acid.
3) annaling
Annealing yog los tshem tawm cov kev ntxhov siab sab hauv hauv electrode, txhim kho lub hom phiaj siv hluav taws xob platege thiab annaling lub hom phiaj tuaj yeem ua tiav los ntawm kev ua kom muaj txiaj ntsig zoo ntawm cov khoom siv kub thiab txias} annaling thiab rauv ib annealing {{}}
Los ntawm cov lus qhia saum toj no rau txoj kev tu ntawm platinum-Rhodium thermocouple, Kuv vam tias nws yuav pab tau txhua tus neeg ua haujlwm thiab kawm.
