API 5L Galvanized kav tsim ib txheej txheej los ntawm reacting molten hlau nrog ib tug hlau substrate, yog li bonding lub substrate thiab txheej ua ke. Galvanizing yog cov txheej txheem ntawm thawj pickling steel kav. Txhawm rau tshem tawm cov hlau oxide los ntawm qhov chaw ntawm cov kav hlau, tom qab pickling, lawv raug ntxuav hauv ammonium chloride los yog zinc chloride aqueous tov los yog sib tov ntawm ammonium chloride thiab zinc chloride aqueous tov tank, thiab ces xa mus rau ib tug kub-dip. plating tank.
Galvanizing muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion, thiab kev pab lub neej ntev. Cov kub-dip galvanized steel yeeb nkab substrate undergoes complex lub cev thiab tshuaj tshuaj tiv thaiv nrog cov molten plating tov, tsim ib tug corrosion-resistant thiab nruj nreem txheej zinc hlau alloy txheej. Cov txheej txheej hlau yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel substrate, yog li nws cov corrosion kuj muaj zog.

Cov kauj ruam ntau lawm
Cov txheej txheem ntws yog raws li nram no: lub raj dub - alkaline ntxuav - dej ntxuav - acid ntxuav - yaug nrog dej huv - soaking tus neeg saib xyuas - ziab - kub-dip galvanizing - sab nraud tshuab - sab hauv tshuab - cua txias - dej txias - passivation - dej yaug - tshuaj xyuas - ntsuas - khaws cia.
Daim ntawv thov khoom
Galvanized steel kav yog dav siv nyob rau hauv manufacturing industries xws li kev tsim kho, machinery, thee mines, tshuaj, hluav taws xob, railway tsheb, automotive kev lag luam, txoj kev loj, txuas hniav, ntim, chaw ua si, kev ua liaj ua teb machinery, roj av machinery, mining machinery, tsev cog khoom siv, thiab lwm yam .
Txoj kev tshem tawm xeb
1. Ua ntej, siv cov kuab tshuaj los ntxuav cov hlau kom tshem tawm cov organic teeb meem ntawm qhov chaw,
2. Tom qab ntawd siv lub cuab yeej tshem tawm xeb (xov hlau txhuam), tshem tawm cov nplais xoob lossis tilted, xeb, vuam slag, thiab lwm yam.
3. Siv txoj kev ntxuav cov kua qaub.
Galvanization yog muab faib ua kub plating thiab txias plating. Kub plating tsis tshua muaj rusting, thaum txias plating yog feem ntau rusting.
