Cov txheej txheem tseem ceeb rau kev tiv thaiv corrosion ntawm steel-cored aluminium stranded hlau muaj xws li siv cov tshuaj tiv thaiv- corrosion, siv alloy plating, siv ib qho txhuas-clad steel core qauv, thiab siv cov ntaub ntawv tshiab corrosion-resistant. Cov txheej txheem no tuaj yeem txuas ntxiv lub neej ntawm tus neeg xyuas pib thiab ua kom muaj kev nyab xeeb ntawm kev xa hluav taws xob.
Nyob rau hauv ib puag ncig corrosive heev xws li cov ntug hiav txwv dej thiab thaj chaw uas muaj kuab paug hnyav, steel -cored aluminium stranded hlau feem ntau qhia tau hais tias muaj zog corrosion nyob rau hauv 4-8 xyoo. Yog li ntawd, nws yog ib qho tseem ceeb rau kev tswj xyuas cov kev pheej hmoo corrosion los ntawm kev hais txog ob qho tib si xaiv cov khoom siv thiab kev tiv thaiv thev naus laus zis.
Cov lus piav qhia ntxaws ntxaws ntawm Kev Tiv Thaiv Kev Tiv Thaiv - Kev Tiv Thaiv corrosion
Txheej nrog Anti-corrosion Roj (Anti-corrosion Roj)
Qhov no yog ib txwm siv los tiv thaiv - txoj kev corrosion. Nws suav nrog txheej txheej tus neeg xyuas pib nrog cov tshuaj tiv thaiv- cov roj xeb los tsim cov txheej txheem ntawm lub cev, tiv thaiv cov dej noo, tshuaj tsuag ntsev, thiab lwm yam corrosive xov xwm los ntawm kev nkag mus rau hauv cov hlua khi.
Anti-cov roj corrosion zoo cais cov tshuaj tiv thaiv electrochemical ntawm aluminium hlau thiab cov tub ntxhais hlau, tiv thaiv electrochemical corrosion. Raws li thaj tsam txheej, nws tau muab faib ua lub teeb tiv thaiv- hom corrosion (steel core nkaus xwb), nruab nrab anti-corrosion hom (steel core + puab txhuas hlau), thiab hnyav tiv thaiv -corrosion hom (tag nrho txheej).
Cov kev tshawb fawb qhia tau hais tias siv cov tshuaj tiv thaiv- cov roj xeb tuaj yeem txuas ntxiv lub neej ntawm cov hlau -core aluminium stranded hlau los ntawm kwv yees li 10 xyoo.
Alloy txheej hloov cov txheej txheem zinc plating. Cov tsoos galvanized steel cores tau yooj yim corroded; tam sim no, ntau dua corrosion-resistant alloy coatings yog dav siv:
Zinc- aluminium alloy txheej: Corrosion kuj yog 2-7 npaug ntawm cov zinc txheej zoo tib yam, muaj ob qho kev tiv thaiv cathodic thiab ntom ntom oxide zaj duab xis dual kev tiv thaiv mechanism.
55% aluminium-zinc alloy txheej: Ua kom ruaj khov oxide zaj duab xis rau ntawm qhov chaw, txo qis tus nqi corrosion, haum rau cov av noo thiab siab ntsev.
Lub ntiaj teb tsis tshua muaj zinc-aluminium alloy txheej: Muaj kev tiv thaiv zoo - kev laus thiab tus kheej - kho muaj peev xwm, sawv cev rau cov kev taw qhia tseem ceeb ntawm kev txhim kho thev naus laus zis.
Aluminium-clad steel core qauv. Aluminium-clad steel tub ntxhais yog tsim los ntawm kev txuas txuas ntxiv ntawm cov hlau hlau nto nrog txhuas nyob rau hauv qhov kub thiab txias, tsim cov khoom siv sib xyaw metallurgically sib xyaw. Aluminium txheej yog kwv yees li 8μm tuab, zoo cais cov tub ntxhais hlau los ntawm ib puag ncig sab nraud.
Nws kiag li zam electrochemical corrosion los ntawm kev sib cuag ncaj qha ntawm hlau thiab txhuas.
Cov kev tshawb fawb qhia tau hais tias lub neej ntawm txhuas-clad steel core aluminium stranded hlau yog ntau tshaj ob npaug ntawm cov qauv zoo tib yam.
Siv cov ntaub ntawv tshiab thiab cov txheej txheem:
Nrog rau kev nce qib hauv cov ntaub ntawv tshawb fawb, ntau yam kev daws teeb meem tshiab tau raug txhawb thiab siv:
Carbon fiber composite core conductor: Hloov cov tub ntxhais hlau nrog cov ntaub ntawv organic sib xyaw, tsim nyog tshem tawm cov teeb meem hlau corrosion.
Ceramic zaj duab xis kho: Tsim cov tshuaj tiv thaiv-corrosion ceramic zaj duab xis rau ntawm tus neeg xyuas pib nto los ntawm thermo-electrochemical oxidation, kuj muab kev ua haujlwm tiv thaiv -icing.
W61-3 silicone resin txheej: Muaj qhov kub thiab txias thiab huab cua tsis kam, haum rau thaj chaw huab cua huab cua.
Environmental Management and Operation Maintenance:
Kev tshuaj xyuas tsis tu ncua, tsom rau kev saib xyuas cov qib ntawm galvanized txheej corrosion thiab tus neeg xyuas pib sag hloov.
Teeb tsa cov ntsiab lus saib xyuas corrosion nyob rau hauv cov cheeb tsam corrosive heev los saib xyuas tus nqi corrosion hauv lub sijhawm.
Kev tswj xyuas kom raug tshem tawm kom raug thaum lub sij hawm tsim kho nyob ze ntawm txoj kab kom tsis txhob muaj kev puas tsuaj sab nraud rau cov txheej txheem tiv thaiv.
