Cov khoom ntawm kub-dip galvanized steel S350GD

 

S350GD galvanized steel ntawv / phaj yog qis- alloy siab- lub zog steel coated nrog zinc txheej kom zoo dua corrosion kuj. Nws yog tshwj xeeb tshaj yog haum rau qhov hnyav ib puag ncig, zoo li huab cua hauv hiav txwv, qhov twg corrosion tuaj yeem yog qhov teeb meem loj dua. Nrog lub zog tawm los tsawg kawg yog 350 MPa, feem ntau siv hauv kev lag luam xws li kev tsim kho, tsheb, thiab khoom siv hauv tsev, rau tej yam xws li ru tsev, lub cev tsheb, thiab cov khoom siv sab nrauv.

 

Cov hlau yog tsim los ntawm cov khoom xws li hlau, carbon, manganese, thiab silicon. Qhov kev sib xyaw ua ke no muab lub zog koj xav tau, thaum tseem ua rau nws yooj yim rau kev ua haujlwm nrog thiab tiv taus corrosion.

 

Lub thickness ntawm zinc txheej tuaj yeem hloov kho raws li qhov nws tau siv rau, txhim kho corrosion kuj thiab adaptability. Nws kuj tseem yooj yim rau txheej txheem, txawm tias koj tab tom stamping, dabtsi yog khoov, lossis vuam, yog li nws ua haujlwm zoo rau ob qho tib si txias - tsim thiab kub - cov khoom tsim.

S350GD muab lub zog siab nrog kev ua haujlwm zoo heev thiab ntev - tiv thaiv corrosion. Qhov tseem ceeb tshaj qhov tseem ceeb ntawm cov cuab yeej cuab tam tuaj yeem pom hauv cov lus saum toj no.

Cov yam ntxwv tseem ceeb no ua rau muaj kev ruaj ntseg load-cov kabmob muaj peev xwm txawm tias nyob rau hauv qhov hnyav lossis cuam tshuam. Qhov kub-dip galvanized nto (+Z) muaj kev tiv thaiv corrosion yooj yim. Vim cov variants

+ Z (ntshiab galvanized):
Txuj kev tiv thaiv corrosion rau cov xwm txheej.

+ZF (zinc{1}}hlau):
Txhim kho txheej adhesion thiab muaj zog tiv thaiv kev ntxhov siab.

+ZA (zinc-aluminium):
Optimized kuj nyob rau hauv atmospheric ib puag ncig.

+ZM (zinc{1}}magnesium):
Ntxiv kev tiv thaiv nyob rau hauv maritime thiab saline zones los ntawm passivating cwj pwm.

+ AZ (aluminium-zinc):
Kev sib xyaw ua ke ntawm kev tiv thaiv tshav kub thiab kev tiv thaiv corrosion, zoo tagnrho rau qhov kub thiab txias.

+AS (aluminium-silicon):
Tshwj xeeb tshaj yog rau cov ntawv thov nrog huab cua kub influences thiab siab corrosion loads.

Tsis zoo li cov hlau galvanized zoo tib yam, qhov sib txuam ntawm cov khoom muaj zog thiab txheej tuab hauv S350GD galvanized steel ua kom muaj kev ruaj khov hauv cov cua kub siab thiab qhov chaw corrosion siab. Yog tias koj tab tom ntsib kev xaiv cov khoom tsis meej pem lossis xav tau los sib piv qhov sib txawv ntawm cov qib sib txawv ntawm cov hlau galvanized, thov koj xav tiv tauj peb rau ib qho - ntawm - ib qho kev pab sab laj txhua lub sijhawm.
