Yuav ua li cas PRTs tiv taus kub kub oxidation?

Kev kub siab oxidation yog ib qho kev hem thawj rau kub sensors ua hauj lwm nyob rau hauv huab cua kub ib puag ncig, xws li furnaces, boilers, gas turbines, thiab industrial processing systems. Ntawm qhov kub siab, cov pa oxygen thiab cov pa paug hauv huab cua tuaj yeem ua rau cov khoom siv sensor degrade, ua rau tsis muaj zog, thiab ua rau lub neej ua haujlwm luv. PRTs tshwj xeeb muaj peev xwm tiv taus oxidation vim muaj cov khoom siv hauv platinum thiab kev tsim qauv tsim. Platinum, lub ntsiab lus tseem ceeb, yog cov hlau zoo uas tseem muaj tshuaj lom neeg ruaj khov txawm tias kub heev. Nws tsis hnov ​​​​mob nrog cov pa oxygen, corrosive gases, los yog cov kab mob, ua kom muaj kev tiv thaiv zoo ib yam - tus cwj pwm kub thaum lub sij hawm. Tsis zoo li cov hlau hauv paus uas oxidize thiab degrade, platinum tswj nws lub cev thiab hluav taws xob yam tsis muaj deterioration. Cov ntaub ntawv sheath kuj plays lub luag haujlwm tseem ceeb hauv oxidation tsis kam. Siab - kub PRTs feem ntau siv Inconel, stainless hlau, lossis ceramic sheaths uas tsim cov txheej tiv thaiv oxide, tiv thaiv kev degradation ntxiv. Cov ntaub ntawv no tiv taus kub txog 850℃lossis siab dua thaum tswj kev ua haujlwm zoo. Hermetically kaw kev tsim kho tiv thaiv cov pa oxygen thiab cov pa phem los ntawm kev nkag mus rau lub cev sensor thiab tiv tauj cov khoom siv sab hauv. Magnesium oxide rwb thaiv tsev tseem nyob ruaj khov ntawm qhov kub thiab txias thiab tsis tawg lossis tso tawm cov kab mob. Ua ke, cov yam ntxwv no tso cai rau PRTs tswj qhov raug thiab kev ntseeg siab hauv oxidizing siab - qhov kub thiab txias. Los ntawm kev tiv thaiv oxidation thiab degradation ntawm cov khoom, PRTs muab ruaj khov, ntev -kev ua tau zoo nyob rau hauv cov ntawv thov uas lwm cov sensors sai sai. Qhov kev tiv thaiv no ua rau lawv tsis muaj qhov tseem ceeb rau kev ntsuas kub siab mus tas li - ntsuas kub hauv kev lag luam hnyav.
