1. Dab tsi yog qhov sib txawv hauv cov tshuaj tiv thaiv corrosion corrosion?
Yooj yim tiv thaiv corrosion: zinc txheej ntawm dog dig corrugated daim ntawv (tshuaj tua kab mob anode + lub cev thaiv kev); zinc txheej ntawm galvanized xim-coated corrugated sheet (tib yam cuam tshuam).
Txheej Txheem Tiv Thaiv Ntxiv: Zinc Txheej ntawm Qhov Nruab Nrab Galvanized Corrugated Daim Ntawv Tsis Muaj Kev Tiv Thaiv Ntxiv; Zinc Txheej ntawm Galvanized Xim-coated Corrugated ntawv muaj organic txheej composite system (Primer + Topcoat + rov qab xim)
Cov Txheej Txheem Kev Tiv Thaiv Mechanism: Galvanized Galvanized Corrugated Ntawv yog feem ntau muaj kev tiv thaiv los ntawm kev txi anode ntawm zinc; galvanized xim-coated corrugated daim ntawv yog lub leb laij lej ntawm kev sib cais ntawm lub cev cais + tshuaj passive tiv thaiv {}}
2. Yuav ua li cas txoj kev txhim kho hauv kev tiv thaiv corrosion corrosion?
Tseem ceeb txuas ntxiv ntawm atmospheric corrosione lub neej
Cov ntawv xim-txheej: Lub neej ntawm cov ntawv xim yog 2 txog 6 zaug ntawm cov ntawv loj hauv galvanized galvanized rau {}}
Txhim Kho Cov Kos Thiab Txiav Corrosion Kuj
Cov ntawv txiav zoo tib yam nkaus, khawb yuav ua kom muaj kev mob ", txheej dorrosion", thiab zinc txheej yuav nrawm .
Organic txheej ntawm cov ntawv xim-txheej: muab cov teeb meem zoo siv lub cev kom muaj kev puas tsuaj tshuab; Tus thawj primer muaj cov passivators xws li chromate, uas tuaj yeem ncua kev kis ntawm corrosion ntawm kev txiav; Tus kheej kho cov thaj chaw ntawm lub sab hauv sab hauv (tshwj xeeb yog PVDF) me ntsis npog me me ntsuab.
Yooj yim zoo rau tshuaj corrosion tsis kam
Zoo ib yam galvanized ntawv: tsis muaj zog acid thiab alkali ua kom muaj roj av thiab muaj kua roj hmab kom nrawm dua ntawm cov txheej zinc ntawm zinc txheej {}}
Cov ntawv xim-txheej: Topcoat (xws li PVDF, Epoxy Primer) muaj kua qaub zoo, alkali thiab feem ntawm cov kev tsis kam; tuaj yeem tiv thaiv cov qias neeg xws li so₂, Nox thiab acid los nag erosion .
Anti-ultraviolet thiab ntub dej kub laus muaj peev xwm
Cov txheej zinc zinc yuav hmoov thiab ua tsis tiav ntev ntev hluav taws xob . Daim duab zincet, tshwj xeeb yog cov txheej txheem zinc thiab tiv thaiv cov zinc txheej hauv qab.
3. Cov ntsiab lus tseem ceeb tshaj plaws uas pom tau ntau ntxiv?
Los ntawm kev tiv thaiv ib leeg rau kev tiv thaiv system:
Cov txheej txheem xim ua rau cov tsis xws luag zoo nkauj
Tus nqi corrosion yog txo qis heev:
Hauv kev kuaj ntsev tsuag tshuaj (Astm B117): Cov Ntawv Galvanized: Dawb Puam tshwm hauv 72 teev;
Cov ntawv zoo xim-txheej txheem (PVDF): Tsis muaj kev txawv txav rau ntau tshaj 1000 teev .
Txo cov nqi ntawm lub neej:
Txawm hais tias thawj daim nqi ntawm cov ntawv xim-coated yog 30% 100% siab dua, lub sijhawm saib xyuas ntev dua thiab cov neeg hloov pauv ntau zaus}
4. Dab tsi yog qhov kev ceev faj rau kev siv cov xim-coated galugal cov ntawv?
Txiav kev tiv thaiv: txoj kev txiav ntug yuav tsum tau pleev xim nrog cov xim tshwj xeeb, txwv tsis pub nws tseem yuav yog qhov tsis muaj zog rau kev xeb;
Zam kev sib cuag nrog cov tub ceev xwm muaj zog: ncaj qha tawm hauv cov kua qaub lossis muaj zog alkali tseem yuav puas tsuaj rau txheej;
Kev xaiv thiab txuam nrog ib puag ncig: PVDF lossis tuab zaj duab xis SMP txheej yuav tsum tau siv nyob rau hauv ntug hiav txwv .
5. Nyob rau hauv cov dab tsi los tiv thaiv corrosion kev ua tau zoo ntawm galvanized xim manifest daim ntawv manifest?
LIFPANGAN: Hauv tib qho chaw ib puag ncig, nws lub neej kev pabcuam yog ntau tshaj 2 ~ 6 zaug ntawm daim ntawv galvanized; Kev tiv thaiv lub zog: los ntawm kev vam khom "Passive ntawm cov txheej zinc
Kev lag luam efficiency: tus nqi ntawm tag nrho lub neej yog txo los ntawm kwv yees li 30% ~ 50% (hloov tus nqi kho / hloov pauv)}
