Cov khoom siv twg yog qhov tsim nyog tshaj plaws rau kev tsim cov tshuaj tiv thaiv corrosion-resistant kub sojntsuam?

Nyob rau hauv cov kev pab cuam nyob rau hauv uas kub sojntsuam yog uncovered rau corrosive ib puag ncig, xaiv cov ntaub ntawv tsim nyog yog ib qho tseem ceeb kom paub tseeb tias cov kev ntsuas raug thiab lub sij hawm ntev durability. Cov ntaub ntawv corrosive tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom qub, qhov tseem ceeb rau kev nyeem ntawv tsis raug thiab tsis ua raws sijhawm ntawm kev sojntsuam.
Thermocouples feem ntau yog siv los ua qhov ntsuas kub hauv ntau qhov kev lag luam thiab kev kho mob. Nyob rau hauv ib puag ncig corrosive, cov khoom tshwj xeeb yuav tsum tau saib xyuas lub thermocouple thiab xyuas kom tseeb tias nws qhov tseeb thiab lub neej ntev. Ib daim ntaub no zoo kawg nkaus tsim nyog rau kev tiv thaiv corrosion-resistant kub sojntsuam yog Inconel. Inconel yog npib tsib xee-chromium-tseem ceeb raws li superalloy tag nrho uas muab kev tiv thaiv corrosion sab saum toj. Nws tuaj yeem tiv thaiv kev tshaj tawm rau ntau yam khoom siv corrosive, nrog rau cov kua qaub, alkalis, thiab ntsev. Inconel thermocouples feem ntau siv rau hauv cov chaw ua tshuaj, cov roj refineries, thiab cov kev lag luam sib txawv uas qhov chaw muaj corrosive.
Lwm daim ntaub uas yuav siv tau rau corrosion-resistant kub soj ntsuam yog Hastelloy. Hastelloy yog ib lub voj voog ntawm cov txheeb ze ntawm npib tsib xee-tseem ceeb raws li cov alloys tau lees paub rau nws qhov kev tiv thaiv corrosion saum toj kawg nkaus. Lawv tuaj yeem tiv thaiv kev ua phem los ntawm ntau cov xov xwm corrosive, ua ke nrog cov kua qaub thiab cov oxidizing cov neeg ua haujlwm. Hastelloy thermocouples nquag siv hauv cov haujlwm uas yuav tsum tau muaj kev tiv thaiv corrosion hnyav, uas suav nrog hauv kev lag luam aerospace thiab nuclear.
Titanium kuj yog ib daim ntaub uas yuav siv tau rau corrosion-resistant kub soj ntsuam. Titanium muaj qhov zoo tshaj plaws corrosion tsis kam rau ntau yam tshuaj lom neeg thiab nquag siv hauv cov kev pab cuam uas muaj dej hiav txwv lossis cov kua dej sib txawv. Titanium thermocouples yog lub teeb yuag thiab muaj lub zog zoo txhua yam, ua rau lawv tsim nyog siv rau hauv qhov chaw hnyav.
Ntxiv nrog rau cov tshuaj no, muaj ntau txoj hauv kev uas yuav tsum tau muaj kev vam khom rau qhov tshwj xeeb corrosive ib puag ncig thiab kev ceeb toom. Piv txwv li, cov khoom siv ceramic tuaj yeem siv rau qhov kub thiab txias heev thiab muaj kev cuam tshuam zoo heev. Ceramics yog inert thiab tuaj yeem tiv taus qhov kub thiab txias thiab cov ntaub ntawv corrosive. Txawm li cas los xij, ceramic probes tuaj yeem nkig ntau dua thiab yuav tsum tau ceev faj tuav.
Lub siab xav ntawm daim ntaub rau ntau lawm corrosion-resistant kub sojntsuam yog nyob ntawm ntau yam, nrog rau daim ntawv ntawm corrosive ib puag ncig, kub ntau yam, mechanical zog yuav tsum, thiab tus nqi. Los ntawm kev ceev faj xav txog cov xwm txheej no, cov ntaub ntawv tsim nyog tshaj plaws yuav raug txiav txim siab kom paub tseeb tias qhov ntsuas kub zoo thiab muaj kev ntseeg siab nyob rau hauv ib puag ncig corrosive.
