Corrosion Resistance Ranking: Titanium Alloy vs Stainless Hlau Electrolysis Cua sov Tube nrog Thermocouple Calibration
Kev xaiv cov khoom siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob ncaj qha cuam tshuam rau qhov ntsuas qhov ntsuas qhov tseeb ntawm kev txhawb nqa thermocouples thiab ntev -lub sijhawm ua haujlwm ruaj khov ntawm cov cua sov. Ntau tus neeg siv tsis quav ntsej txog kev sib raug zoo ntawm lub raj lub cev tiv thaiv kev tiv thaiv thiab cov nyhuv thermocouple. Corroded thiab scaled cua sov tube qhov chaw ua rau tsis sib xws ntawm tshav kub conduction thiab lub zos kub sib txawv, ua rau thermocouple teeb liab drift thiab tsis raug kub tswj. Kev nthuav qhia cov khoom sib txawv ntawm qhov sib txawv pab kom paub txog kev ua kom zoo dua qub ntawm cov cua sov kom ruaj khov thiab ntsuas qhov ntsuas kub.
Tshwj xeeb titanium alloy cua sov raj ua qhov kev xaiv rau siab -concentration electrolyte cua sov scenarios. Titanium alloy cov ntaub ntawv feature ultra- tsis tshua muaj tshuaj lom neeg kev ua si thiab zoo heev tiv thaiv electrolytic ion corrosion, tuav du thiab tsis yog -scaling tube nto nyob rau hauv ntev-lub sij hawm sib cuag nrog acidic, alkaline thiab siab - salinity electrolysis dej. Raws li kev sim cov ntaub ntawv, titanium alloy tube lub cev tsis muaj qhov pom tseeb corrosion thiab scaling tshwm sim tom qab 5000 teev ntawm kev ua haujlwm tas mus li hauv siab -concentration electrolyte, kom ntseeg tau tias cov cua sov tsis sib xws thiab qhov kub thiab txias nyob ib puag ncig cov ntsiab lus ntsuas thermocouple.
316L stainless hlau cua sov raj hloov mus rau cov pa qis -concentration electrolysis ua hauj lwm tej yam kev mob. Nrog nruab nrab corrosion kuj thiab nqi kev ua tau zoo, 316L stainless hlau tuaj yeem tiv nrog cov hluav taws xob tsis muaj zog thiab cov dej kub ionized zoo ib puag ncig. Nyob rau hauv qis - corrosion kuj ua hauj lwm tej yam kev mob, lub raj lub cev muaj kev ruaj ntseg thermal conduction kev ua tau zoo, thiab cov thermocouple sib phim tuaj yeem tau txais cov cim kub tsis tu ncua thiab raug. Txawm li cas los xij, nyob rau hauv qhov chaw siab -concentration electrolyte ib puag ncig, stainless hlau nto yog qhov yooj yim rau pitting corrosion thiab sediment tsub zuj zuj, ua rau qhov kub thiab txias hauv cheeb tsam sib txawv thiab ntsuas qhov sib txawv ntawm thermocouple.
Ordinary 304 stainless hlau raj muaj qhov kev txwv tsis pub siv hauv electrolysis scenarios. Cov khoom siv tsis zoo rau electrolytic ion yaig, thiab lub sijhawm ua haujlwm ntev - yuav tsim oxide scaling rau saum npoo. Scaling khaubncaws sab nraud povtseg tsim thermal tsis kam thiab ua rau qhov kub tsis sib xws, ua rau cov ntaub ntawv kuaj xyuas cov thermocouple tsis tuaj yeem cuam tshuam cov dej kub tiag tiag. Kev siv sijhawm ntev - yuav ua rau muaj kev tswj qhov kub thiab txias tsis tu ncua thiab ua kom muaj kev laus ntawm cov raj cua sov.
Qhov kev ua tau zoo sib xws ntawm cov khoom siv cua sov sib txawv thiab kev kuaj xyuas cov thermocouple hauv electrolysis scenarios yog txheeb hauv cov lus hauv qab no:

Ntev- cov ntaub ntawv tshawb xyuas qhov xwm txheej qhia tau hais tias titanium alloy cua sov cov raj sib txuam nrog siab -cov thermocouples qhov tseeb txo cov txheej txheem kub ntawm electrolysis los ntawm 76% piv nrog cov qauv zoo tib yam stainless hlau. Kev ua haujlwm ruaj khov ntawm lub cev ua haujlwm tsim kom muaj qhov tsis tu ncua - qhov chaw ntsuas qhov ntsuas kub rau cov thermocouples, txhim kho cov txheej txheem tsim nyog tus nqi.
Kev cob qhia cov khoom sib xws thiab ntsuas kub ntsuas qhov ntsuas kub tuaj yeem xaiv cov khoom siv cua sov tshwj xeeb thiab cov thermocouple hom raws li ntawm -site electrolyte concentration thiab pH tus nqi, paub txog siab -precision thiab ntev- lub neej ua haujlwm ntawm electrolysis cua sov tshuab.
