Lub neej ntev ntawm steel -cored aluminium stranded hlau yog cuam tshuam zoo heev los ntawm cov ntaub ntawv, ib puag ncig, thiab kev tiv thaiv. Nyob rau hauv ib txwm muaj, nws tsim lifespan yog nyob ib ncig ntawm 30 xyoo, tab sis nyob rau hauv heev corrosive ib puag ncig, nws tsuas kav 4-8 xyoo.
Kev piav qhia ntxaws txog yam cuam tshuam rau lub neej
Basic Design Lifespan: Cov qauv tsim qauv lifespan ntawm steel -cored aluminium stranded hlau yog 30 xyoo. Daim duab no yog ua raws li kev soj ntsuam zoo nyob rau hauv qhov zoo tshaj plaws nteg tej yam kev mob (xws li dryness, tsis muaj kuab paug, thiab nruab nrab kub). Nws txheej txheej aluminium muaj qhov ruaj khov, thiab cov tub ntxhais hlau sab hauv muab kev txhawb nqa lub sijhawm ntev -.
Corrosive Environments Shorten Lifespan: Nyob rau hauv cov cheeb tsam corrosive heev xws li cov ntug dej hiav txwv thiab cov cheeb tsam uas muaj kuab paug hnyav, steel -cored aluminium stranded hlau feem ntau qhia tau hais tias muaj zog corrosion tom qab 4-8 xyoo, yuav tsum tau hloov raws sij hawm kom muaj kev nyab xeeb ntawm kev xa hluav taws xob. Cov laj thawj tseem ceeb yog:
Electrochemical corrosion tshwm sim los ntawm huab cua ntub thiab ntsev tsuag.
Kev yaig ntawm cov galvanized steel core txheej ua rau txo qis ntawm cov qauv siv zog.
Oxidation ntawm aluminium hlau nto tsub kom tsis kam, cuam tshuam conductivity.
Qhov sib txawv ntawm lub neej ntawm cov khoom tseem ceeb. Nyob rau hauv steel -cored aluminium stranded hlau, qhov tseeb lifespan ntawm lub load-cov kabmob galvanized steel hlau tsuas yog 10-15 xyoo, luv luv tshaj li qhov tsim lifespan ntawm tag nrho cov hlau, dhau los ua ib tug bottleneck txwv tag nrho cov kev pab cuam lub neej.
Cov khoom siv thiab kev txhim kho thev naus laus zis tuaj yeem txuas ntxiv lub neej ntev.
Txheej nrog cov tshuaj tiv thaiv-corrosion roj: tuaj yeem txuas lub neej ntev li 10 xyoo, haum rau qhov chaw me me mus rau nruab nrab corrosive ib puag ncig.
Alloy txheej: hloov cov txheej txheem zinc txheej, txhim kho kev tiv thaiv corrosion, thiab yog cov txheej txheem thev naus laus zis tam sim no.
Aluminium-clad steel core qauv: tsim cov khoom sib xyaw los ntawm kev sib txuas ntawm metallurgical, tsis txhob xeb los ntawm kev sib cuag ntawm cov hlau tsis sib xws, thiab tuaj yeem ua rau muaj sia nyob ntau dua 100%.
