Cov pa tooj liab-dawb, ua cov khoom lag luam tooj liab siab, yog siv dav hauv ntau daim teb vim nws txoj kev ua haujlwm hluav taws xob zoo, thermal conductivity thiab cov khoom siv tshuab. Txawm li cas los xij, hauv cov ntawv thov siv, cov xeb pheej ua haujlwm ntawm cov khoom kuj tseem yog qhov ntsuas tseem ceeb uas tsis tuaj yeem tsis quav ntsej. Rau cov pa oxygen-dawb tooj liab, nws yog nws corrosion tsis kam? Hauv daim ntawv no, peb yuav tham txog cov xeb ntawd ntawm cov pa oxygen-dawb, thiab piav qhia qhov tseem ceeb ntawm kev siv cov pa oxygen-dawb.
Ua ntej, cov corrosion tiv taus ntawm cov pa-dawb tooj yeeb cov yeeb nkab nta
Cov pa tooj liab-dawb raj corrosion yog heev heev heev, uas yog vim nws cov kev kho siab tooj liab thiab cov txheej txheem kev kho mob tshwj xeeb. Tshwj xeeb, cov corrosion tsis kam ntawm cov pa oxygen-dawb tooj liab yog cov cim raws li hauv qab no:
1. Cov khoom siv corrosider tsis kam: oxygen-tooj liab tub ua tau zoo nyob rau hauv ib puag ncig huab cua chaw thiab tuaj yeem ua tsis taus oxidation thiab corrosion. Txawm nyob rau hauv ib puag ncig hnyav xws li cov av noo thiab ntsev, oxygen-tooj liab leeg tuaj yeem tswj hwm corrosion zoo.
2. Cov tshuaj zoo corrosion: oxygen-dawb tooj yeeb muaj high corrosion tsis kam rau ntau yam tshuaj lom neeg. Piv txwv li, hauv cov acidic ib puag ncig xws li dilute suluguric acid, corrosen rasistance ntawm cov pa-dawb tooj liab zoo dua li lwm cov khoom hlau.
3. Ruaj Ntseg Electrochemical Corrosion Kuj: hauv electrochemical Corrosion, Oxygen-Free Tooj Tube qhia tau corrosion ruaj khov. Qhov no ua rau nws dav hauv cov khoom siv hluav taws xob, Cheebtsam hluav taws xob thiab lwm thaj teb.
Qhov thib ob, qhov cuam tshuam cuam tshuam rau cov corrosion tsis kam ntawm cov pa oxygen-dawb tooj raj
Txawm hais tias tus corrosion tsis kam ntawm cov pa oxygen-dawb heev, tab sis tseem muaj qee yam uas yuav cuam tshuam rau kev ua tau zoo ntawm nws corrosion tsis kam. Cov hauv qab no yog qee qhov cuam tshuam loj:
1. Tshuaj lom neeg sib xyaw: cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov pa oxygen-dawb muaj qhov cuam tshuam tseem ceeb ntawm nws corrosion tsis kam. Cov ntsiab lus tooj liab purper tseem yuav pab txhim kho lub corrosion tsis kam ntawm cov pa oxygen-dawb. Nyob rau tib lub sijhawm, ntxiv rau lwm cov ntsiab lus alloy yuav muaj kev cuam tshuam rau corrosion tsis kam. Piv txwv li, ntxiv tus nqi npib tsib xee, chromium thiab lwm cov ntsiab lus tuaj yeem txhim kho cov yeeb nkab doligen tiv thaiv oxygen.
(2) Tus qauv tswj hwm: Tus qauv tswjfwm ntawm cov pa oxygen-dawb tooj liab lub luag haujlwm tseem ceeb tshaj plaws hauv nws txoj kev txhim kho corrosion. Ntev, cov qauv tsis sib thooj pab txhawm rau txhim kho lub corrosion tsis kam ntawm oxygen-dawb tooj raj. Ntawm qhov tsis sib xws, coarse nplej, lub koom haum tsis sib xws thiab lwm yam tsis xws luag yuav ua rau poob rau hauv kev ua kom xeb.
(3) Kev kho deg: Cov txheej txheem kho deg ntawm cov txheej txheem-oxygen-dawb tooj nkab cov yeeb nkab tseem muaj ib qho kev cuam tshuam zoo ntawm nws corrosion tsis kam. Tom qab plating, txheej thiab lwm yam kev kho nyob saum npoo ntawm cov pa-dawb tooj liab tuaj yeem txhim kho nws corrosion tsis kam. Piv txwv li, Nickel plating, chrome cov txheej txheem kho mob tuaj yeem txhim kho cov yeeb nkab corrosion tsis kam ntawm cov pa oxygen.
Qhov thib peb, lub corrosion tsis kam ntawm cov pa oxygen-dawb tooj raj thov cuam tshuam
Cov pa oxygen-dawb tooj liab raj corrosion tsis muaj qhov cuam tshuam tseem ceeb rau nws daim ntawv thov. Hauv qab no yog ntau yam ntawm cov kev ua tau tshwj xeeb:
1. Txuas ntxiv lub neej: Zoo tshaj plaws corrosen tsis kam ua cov pa oxygen nyob rau hauv cov txheej txheem ntawm kev siv tsis yooj yim kom tau corroded thiab puas, linting nws txoj kev pabcuam lub neej. Qhov no yog qhov tseem ceeb rau kev txo cov nqi kho thiab txhim kho cov cuab yeej siv tau yooj yim.
2. Txhim Kho Kev Nyab Xeeb: Hauv kev lag luam tshuaj, cov roj av tsis zoo ntawm cov pa roj oxygen yuav pab kom muaj kev nyab xeeb tooj ntawm cov pa, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kev nyab xeeb, tawg thiab lwm yam kev nyab xeeb.
3. Haum rau cov pa hluav taws xob tsis zoo ntawm cov pa oxygen-dawb, xws li kub thiab cua siab, ntsev thiab li ntawd. Qhov no ua rau oxygen tooj-dawb tooj liab raj hauv kev ua si marine engineering, cov khoom siv chemical engineering, khoom siv thiab lwm daim teb tau siv dav.
Qhov thib plaub, yuav ntsuas cov corrosion tsis kam ntawm cov pa oxygen-dawb tooj
Txhawm rau kom ntseeg tau tias cov corrosion tsis kam ntawm cov pa oxygen-dawb ua tau raws li daim ntawv thov thiab kev ntsuas feem ntau yuav tsum muaj. Cov hauv qab no yog qee txoj kev siv siv ntau:
1. Atmberic Corrosion: Cov Oxygen-tooj Tooj Liab Tube thiab nws corrosion yog pom los ntsuas nws tsis kam mus rau atmospheric corrosion.
2. Tshuaj Kho Mob Corrosion: Cov Oxygen Tooj Liab Tube tau muab tso rau hauv cov tshuaj sib txawv, saib seb nws cov tshuaj tiv thaiv kev ua haujlwm tsis kam.
3. Electrochemical Corrosion: Ntsuas cov kev ua kom xeb, corrosion thiab lwm yam tooj liab-introchemical txoj kev los ntsuas nws txoj kev tiv thaiv tshuab hluav taws xob.
