MEa Raws li corrosion inhibitor nyob rau hauv cov hlau thawj deg
1.} Ua haujlwm ua haujlwm ntawm monoethanolamine (mea) raws li corrosion inhibitor
Maje Mas ua tau kev tawm tsam nws cov nyhuv corrosion inshibition los ntawm cov txheej txheem nram qab no:
Adsorption Zaj Duab Xis Tsim:
Cov qauv molecular ntawm cov pab pawg neeg ua yeeb yaj kiab (xws li cov duab ua yeeb yaj kiab) thiab cov duab ua yeeb yaj kiab dej, acidic / alkaline cov tshuaj), yog li inhibit entrochemical corrosion {}}
Ph Haum:
Mea yog alkaline (ph} |
Chelation:
Cov amino pab pawg ntawm mea tuaj yeem tsim soluble complex nrog kev tso tawm hlau los yog corrosion .
{{02. Teb Chaws Yuav Tsum Muaj Cov Ntawv Thov Siv
Kev siv ntawm Mea ib leeg tej zaum yuav cuam tshuam rau kev sib txuam ntawm cov txheej txheem vim yog lwm cov kuab tshuaj lossis cov qauv tshuaj ntxiv rau cov xwm txheej thiab cov qauv hauv lub cev:
Dej Raws Hlau Txheej:
Mea ({1-5%) + sodium molybdate (}}}}}} Cov qauv dej {}
Coolant corrosion inhibitor:
Mea ({2-3%) + borate (1%) + sodium nitrate (0}} 1%), inhibits pitting ntawm txhuas thiab cam khwb cia hlau.
Vapor corrosion (VCI):
Mea tau sib xyaw nrog Benzoate ua kom haum-inhibiting ntawv rau ntim hlau {}}
Lub ntsiab
Mea tuaj yeem siv ncaj qha raws li kev tsim kho corrosion, tab sis nyob rau hauv cov ntawv sau tshwj xeeb, nws feem ntau yog tsim nyog ua kom zoo rau cov hom hlau, ib puag ncig thiab txheej syste .
