Yuav galvanized steel kav xeb

Thaum cov yeeb nkab hlau raug cua thiab raug oxidation tshwm sim nrog oxygen, los yog corroded los ntawm cov pa oxygen hauv dej thiab ua oxides, lawv yuav xeb. Galvanized steel kav tau txais kev kho mob galvanizing los tsim ib txheej galvanized uas cais cov huab cua, ua rau lawv ntau dua corrosion-resistant thiab tsis tshua muaj rusting. Cov kav dej galvanized puas yuav xeb?
Feem ntau hais lus, galvanized steel kav tsis yooj yim rau xeb, tab sis nws tsis txhais hais tias lawv yuav tsis xeb. Nws yog ib qho teeb meem ntawm lub sijhawm. Tom qab siv sijhawm ntev, cov kav dej galvanized tseem yuav xeb; Tsis tas li ntawd, yog tias ib puag ncig siv los yog cov av noo los yog raug los nag ntev, cov kav hlau galvanized yuav sai sai oxidize thiab tsim cov pob, uas yuav ua rau xeb.
Tsis tas li ntawd, muaj ob hom galvanized steel kav: kub-dip galvanized kav thiab txias-dip galvanized kav. Raws li kev hais lus, cov kav dej kub-dip galvanized tsis tshua muaj rusting dua li cov kav dej txias-dip galvanized.
Nws siv sijhawm ntev npaum li cas rau cov kav dej txias galvanized tsis xeb
Lub sijhawm xeb ntawm cov kav dej galvanized feem ntau yog cuam tshuam nrog rau yam xws li galvanizing txoj kev, thickness ntawm galvanized txheej, galvanizing nyiaj, thiab kev siv ib puag ncig. Feem ntau, rusting ntawm cov kav dej txias galvanized yog ceev ceev
Tus nqi galvanizing ntawm txias galvanized steel kav yog qhov tsawg, thiab hom galvanized yeeb nkab no tsuas yog galvanized rau sab nraud, tsis muaj galvanizing rau sab hauv. Cov zinc ntawm ib sab yog li ntawm 20g/㎡, yog li nws yooj yim dua rau xeb. Feem ntau, cov kav dej txias galvanized steel yuav pib xeb tom qab li ib xyoos hauv ib puag ncig siv; Yog hais tias lub thickness yog tuab, lub sij hawm rusting yuav txuas ntxiv. Rau cov qis dua 2.75mm, nws yuav siv sijhawm 2-3 xyoo, thiab rau cov siab dua 3.0mm, nws tuaj yeem siv sijhawm 3-5 xyoo.
Yuav ua li cas tshem tawm xeb los ntawm cov kav dej galvanized
Yog tias cov yeeb nkab galvanized rusts, qee txoj kev tuaj yeem siv rau kev tshem tawm xeb. Txoj kev tshem tawm xeb tseem ceeb rau cov kav dej galvanized yog:
1. Ua ntej, siv cov kuab tshuaj los ntxuav lub ntsej muag ntawm cov hlau thiab tshem tawm cov organic teeb meem ntawm qhov chaw.
2. Tom qab ntawd siv cov cuab yeej xws li cov hlau txhuam kom tshem tawm cov xeb, feem ntau yog siv cov hlau txhuam los txhuam cov xoob xoob lossis tilted xeb, vuam slag, thiab lwm yam.
3. Siv cov kua qaub los ntxuav cov kav dej galvanized, cov xeb ntawm lawv yuav luag tag nrho.
