Vim li cas Titanium Alloy Tube Bundles hauv Chemical Heat Exchangers Corrosion-Resistant?
Hauv cov txheej txheem tshuaj lom neeg, cov khoom siv hluav taws xob sib hloov ua lub luag haujlwm tseem ceeb hauv kev hloov hluav taws xob thiab kev siv hluav taws xob. Raws li cov ntsiab lus tseem ceeb, cov khoom siv hauv lub raj yog nyob rau hauv kev sib cuag ncaj qha nrog ntau yam corrosive media, thiab lawv cov corrosion kuj txiav txim siab txog kev pab cuam lub neej thiab kev nyab xeeb ntawm cov khoom siv. Nrog rau ntau yam tshuaj lom neeg tshaj tawm-xws li cov kua qaub, alkalis, ntsev, thiab cov tshuaj organic complex- cov khoom yuav tsum tau ua raws li qhov xav tau ntau dua. Titanium alloy tube bundles, nrog lawv cov khoom siv tshwj xeeb, ua kom pom kev ua tau zoo nyob rau hauv ib puag ncig corrosive heev thiab tau dhau los ua qhov kev xaiv zoo tshaj rau cov khoom siv hluav taws xob. Lawv cov kev tiv thaiv corrosion tsis yog vim cov khoom siv xwb tab sis kuj tseem cuam tshuam nrog lawv cov yam ntxwv saum npoo thiab ntev - lub sij hawm ruaj khov.
Dense Oxide Zaj duab xis tsim ib qho kev tiv thaiv ntuj
Qhov zoo tshaj plaws corrosion kuj ntawm titanium alloys feem ntau yog los ntawm cov txheej txheem tiv thaiv tsim ntawm lawv qhov chaw:
- Cov yeeb yaj kiab oxide ruaj khov thiab ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom oxide zaj duab xis tsim sai sai hauv huab cua lossis tshuaj lom neeg tshaj tawm, cais cov tshuaj corrosive.
- Cov txheej oxide muaj tus kheej - kho cov khoom, sai sai rov tsim dua txawm tias hauv zos puas
- Zoo tiv thaiv ion nkag mus, txo qhov muaj feem ntawm electrochemical corrosion
Lub ntuj "barrier" no tso cai rau titanium alloy raj bundles kom nyob ruaj khov nyob rau hauv complex tshuaj ib puag ncig.
Cov tshuaj lom neeg tsis muaj zog tiv thaiv ntau yam Corrosive Media
Nyob rau hauv ib puag ncig tshuaj, cov ntaub ntawv feem ntau ntsib ntau yam corrosive ib txhij:
- Tiv thaiv kom muaj zog acids, tsis muaj zog acids, thiab ntau yam ntsev daws
- Ua kom muaj kev tiv thaiv zoo heev rau pitting corrosion hauv chloride - muaj ib puag ncig
- Ua kom muaj zog tiv thaiv corrosion rau cov organic tshuaj lom neeg
Qhov kev ruaj ntseg tshuaj no ua rau cov titanium alloys ua kom tau raws li cov txheej txheem tshuaj lom neeg.
Zoo heev Resistance rau Localized Corrosion
Localized corrosion yog ib qho tseem ceeb ua rau lub tshav kub exchanger tsis ua hauj lwm, thiab titanium alloys ua tau zoo heev nyob rau hauv no hais txog:
- Muaj zog tsis kam mus rau pitting, tiv thaiv kev tsim ntawm corrosion qhov
- Zoo heev tiv thaiv crevice corrosion, haum rau complex structural cheeb tsam
- Resistant rau corrosion acceleration nyob rau hauv cov dej ntws thiab yaig tej yam kev mob
Cov khoom no txo qis qhov kev pheej hmoo ntawm cov dej xau los ntawm lub zos corrosion nyob rau hauv cov hnab ntim khoom.
Ntev - Lub Sij Hawm Stability Extens Cov Khoom Siv Lub Neej
Tshaj li luv- lub sij hawm corrosion kuj, ntev - lub sij hawm stability yog qhov tseem ceeb sib npaug:
- Tsis tshua muaj corrosion tsawg heev thaum lub sij hawm ua hauj lwm ntev, ncua kev pab cuam lub neej
- Kev ua tau zoo nyob ruaj khov txawm tias hloov pauv hauv qhov kub thiab txias lossis tshuaj lom neeg tshaj tawm
- Txo kev txij nkawm thiab hloov zaus, txhim kho kev ua haujlwm zoo
Qhov ntev -lub sij hawm ruaj khov no ua rau titanium alloy raj bundles muaj txiaj ntsig zoo hauv kev xav tau cov tshuab tshuaj.
Raws li kev lag luam tshuaj lom neeg tseem xav tau ntau dua ntawm kev nyab xeeb thiab kev ua haujlwm zoo, kev xaiv cov khoom siv rau cov khoom siv hluav taws xob hloov pauv tau nce ntxiv. Titanium alloy raj bundles, los ntawm lawv ntom oxide tiv thaiv, zoo heev tshuaj inertness, thiab superior tsis kam mus rau lub zos corrosion, qhia tau zoo heev corrosion kuj nyob rau hauv complex ib puag ncig. Nyob rau tib lub sijhawm, lawv lub sijhawm ntev - ruaj khov ua rau cov cuab yeej siv tau ntev thiab txo cov nqi tu. Rau cov laj thawj no, titanium alloy tube bundles tau dhau los ua cov khoom siv tseem ceeb hauv kev siv tshuaj tua hluav taws xob, muab kev nyab xeeb dua, txhim khu kev qha, thiab muaj txiaj ntsig zoo rau kev lag luam niaj hnub no.
