Galvanized hlau
Galvanized steel yog carbon hlau coated nrog ib txheej ntawm zinc los tiv thaiv nws los ntawm corrosion. Cov txheej zinc ua raws li ob qho tib si lub cev thaiv thiab kev tiv thaiv kev txi. Nws tiv thaiv cov dej noo, oxygen, thiab cov tshuaj phem los ntawm kev tawm tsam cov hlau nto. Txawm tias thaum txheej txheej yog khawb, cov zinc nyob ib puag ncig corrodes ua ntej, khaws cia cov hlau hauv qab.
Galvanization feem ntau yog ua los ntawm cov txheej txheem kub -dip, qhov twg steel sawb yog immersed nyob rau hauv molten zinc nyob ib ncig ntawm 450 degree. Thaum cov txheej txheem no, zinc- hlau alloy txheej yog tsim thiab metallurgically bonded nrog steel substrate. Qhov kev sib txuas ruaj khov no ua kom lub sijhawm ntev - durability, zoo heev txheej adhesion, thiab zoo corrosion kuj.
Vim nws txoj kev ua tau zoo thiab kev lag luam tsim nqi, galvanized steel yog dav siv hauv kev tsim kho, kev thauj mus los, chaw siv hluav taws xob, khoom siv hauv tsev, thiab kev tsim khoom.
Ntawm tag nrho cov khoom lag luam galvanized,DX51D galvanized steel kaujstands raws li feem ntau dav siv los ua hlau vim nws qhov tshwj xeeb sib npaug ntawm formability, lub zog, nto zoo, thiab kev tiv thaiv corrosion.
Kev txhais lus ntawm DX51D Galvanized Steel
DX51D yog qib kev ua cov hlau uas tau teev tseg raws li EN 10346. Nws yog tsim los rau cov ntawv txias txias xws li dabtsi yog khoov, yob txoj kev, stamping, thiab kos duab sib sib zog nqus. Nws ruaj khov mechanical kev ua tau zoo ua kom cov txiaj ntsig ua tau zoo thiab txo cov khoom tsis raug.

Yog vim li cas DX51D yog qhov nyiam ua qib
DX51D muaj ntau yam zoo:
- Kev ua haujlwm txias txias zoo heev
- ruaj khov mechanical sib xws
- Muaj zog tiv thaiv corrosion
- High nto zoo rau pom daim ntaub ntawv
- Tsawg tus nqi ntawm cov tswv cuab
- Broad compatibility nrog txheej thiab painting systems
Qhov kev sib xyaw no piav qhia vim li cas DX51D tseem yog qhov kev xaiv zoo tshaj plaws rau cov tuam txhab thoob ntiaj teb.
