Cov hlau twg yog qhov zoo tshaj plaws rau kev tsim khoom kub sensors hauv qhov chaw corrosive?

Nyob rau hauv ib puag ncig corrosive, nrhiav cov hlau tsim nyog rau cov ntsuas kub ntau lawm yog qhov tseem ceeb los ua qee qhov kev ntsuas kom raug thiab ntseeg tau. Cov ntaub ntawv corrosive tuaj yeem ua rau cov khoom siv tsis zoo, qhov tseem ceeb rau kev nyeem ntawv tsis raug thiab tsis ua raws sijhawm.
Thermocouples feem ntau yog siv cov ntsuas kub ntsuas hauv ntau pob. Nyob rau hauv ib puag ncig corrosive, tshwj xeeb alloys yuav tsum tau ua kom paub tseeb tias qhov ruaj khov thiab qhov tseeb ntawm thermocouples. Ib qho alloy no tshwj xeeb tshaj yog tsim nyog rau qhov no yog Inconel. Inconel yog nickel-chromium-raws li tag nrho superalloy uas muab zoo corrosion kuj. Nws tuaj yeem tiv thaiv kev tshaj tawm rau ntau yam khoom siv corrosive, xws li acids, alkalis, thiab ntsev.
Inconel thermocouples yog qhov zoo tshaj plaws los siv rau hauv kev lag luam ua ke nrog kev ua tshuaj lom neeg, petrochemicals, thiab hluav taws xob tsim hluav taws xob, nyob rau hauv qhov chaw muaj corrosive. Cov hlau tsis kam tiv thaiv corrosion tso cai rau qee lub sij hawm ntev sib npaug thiab qhov tseeb ntawm qhov ntsuas kub. Tsis tas li ntawd, Inconel muaj lub zog txhua yam thiab tuaj yeem tiv taus qhov kub thiab txias, ua rau nws tsim nyog rau cov pob khoom raug mob.
Lwm alloy uas yuav siv tau rau qhov kub thiab txias sensors nyob rau hauv corrosive ib puag ncig yog Hastelloy. Hastelloy yog ib lub voj voog ntawm cov txheeb ze ntawm npib tsib xee-raws li cov alloys tag nrho tau lees paub rau nws qhov zoo heev corrosion kuj. Lawv tuaj yeem tiv taus kev tawm tsam los ntawm ntau cov xov xwm corrosive, uas suav nrog cov kua qaub ruaj khov thiab oxidizing cov neeg ua haujlwm. Hastelloy thermocouples feem ntau siv rau hauv cov pob khoom uas yuav tsum tau muaj kev tiv thaiv corrosion hnyav.
Qhov kev nyiam ntawm Inconel thiab Hastelloy tso siab rau ntawm qhov tseeb corrosive ib puag ncig thiab kev ceeb toom. Ob lub alloys muab kev tiv thaiv corrosion zoo, txawm li cas los xij lawv yuav muaj ib lub tsev zoo nyob rau hauv cov kab lus ntawm qhov kub thiab txias, lub zog txhua yam, thiab tus nqi. Nws yog ib qho tseem ceeb kom nco qab cov ntsiab lus thaum xaiv qhov siab tshaj plaws tsim nyog alloy rau ntau lawm kub sensors nyob rau hauv corrosive ib puag ncig.
Ntxiv nrog rau Inconel thiab Hastelloy, muaj cov alloys sib txawv thiab cov khoom siv uas tuaj yeem siv tau raws li qhov tseeb corrosive. Piv txwv li, titanium thiab nws cov alloys tau lees paub rau nws qhov kev tiv thaiv corrosion thiab tuaj yeem siv rau hauv ob peb qhov chaw corrosive. Txawm li cas los xij, lawv qhov kub ntau tuaj yeem raug txwv raws li piv rau Inconel thiab Hastelloy.
