Txheej txheem cej luam
Nws tuaj yeem yog peb lub luag haujlwm kom txaus siab rau koj qhov kev nyiam thiab muaj peev xwm muab rau koj. Koj qhov kev txaus siab yog peb qhov khoom plig loj tshaj plaws. Peb tab tom nrhiav ua ntej ntawm koj qhov kev mus ntsib rau kev sib koom ua ke. Vim peb txoj kev siv zog, peb cov khoom tau txais kev ntseeg siab ntawm cov neeg yuav khoom thiab tau txais txiaj ntsig zoo sib npaug ntawm no thiab txawv teb chaws. Peb lub Hoobkas hais txog lub hauv paus ntsiab lus ntawm "Quality First, Sustainable Development", thiab siv "Kev Ua Lag Luam Ncaj Ncees, Kev Sib Koom Siab" raws li peb lub hom phiaj txhim kho. Txhua tus tswv cuab ua tsaug rau txhua tus qub thiab tshiab cov neeg siv khoom txhawb nqa. Peb yuav ua haujlwm hnyav thiab muab cov khoom zoo tshaj plaws thiab kev pabcuam rau koj.
Txog cov pa roj carbon steel welded thiab seamless yeeb nkab, kom muaj peev xwm tiv taus corrosion, yuav muaj qee yam kev kho deg rau cov yeeb nkab. Ib qho ntawm feem ntau siv yog zinc coat (galvanize). Muaj ob txoj kev galvanize: txias glavanizing (electrogalvanizing) thiab kub galvanizing. Vim hais tias ib puag ncig teeb meem, glavanizing txias tau raug txwv nyob rau hauv Suav teb, thiab kub galvanizing kuj tsis tuaj yeem siv los ua cov kav dej, tab sis nws dav siv hauv kev tua hluav taws, hluav taws xob thiab kev loj.
Txias galvanizing yog electrogalvanizing, vim hais tias ntawm kev txwv ntawm cov txheej txheem, zinc lub tsho tiv no tsis ntau, feem ntau nyob rau hauv 10-50g / m2, yog li ntawd, nws muaj peev xwm corrosion kuj yog tsawg dua kub galvanizing. Lub Tsev Haujlwm Saib Xyuas Kev Tsim Kho tau ua tiav qhov kawg ntawm kev tshem tawm cov kav dej txias galvanized nrog cov cuab yeej rov qab, thiab nws yog txwv tsis pub siv cov kav dej txias galvanized rau cov kav dej thiab cov kav dej. Lub galvanized txheej ntawm txias-dip galvanized steel yeeb nkab yog ib txheej electroplated, thiab zinc txheej thiab steel yeeb nkab substrate yog txheej ntawm nws tus kheej. Cov zinc txheej yog nyias nyias, thiab cov zinc txheej tsuas yog ua raws li cov yeeb nkab steel substrate thiab yooj yim poob tawm. Yog li ntawd, nws cov corrosion kuj tsis zoo.
Kub galvanizing yeeb nkab txheej txheej txheej yog tsim los ntawm cov tshuaj tiv thaiv ntawm cov hlau molten thiab hlau substrate, kom cov substrate thiab plating txheej yog ua ke, thiab cov plating txheej tsis yooj yim rau poob. Kub dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion thiab lub neej ua haujlwm ntev. Cov kub-dip galvanized steel yeeb nkab substrate thiab cov molten plating tov undergo complex lub cev thiab tshuaj cov tshuaj tiv thaiv los tsim ib tug corrosion-resistant zinc-hlau alloy txheej nrog ib tug compact qauv. 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.
Daim ntawv thov
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.
