Zinc-Hlau Alloy Hlau ChevPuas yog cov hlau nrog zinc-hlau (zn-fe) txheej txheej corrosion, feem ntau siv los txhim kho corrosion, feem ntau siv los txhim kho corrosion, feem ntau yog ob hom zinc-hlau alloy txheej:
Dinc-Iron Hlau Alloy Txheej (ZN-FE)
Composition: Zinc (85% ~ 95%) + Hlau (5% ~ 15%) {5}.
Txheej Txheem: Cov txheej txheej alloy yog tsim ncaj qha los ntawm kub-dip plating lossis electroplating .
Nta: Cov corrosion tsis zoo dua li ntshiab zinc (Gi), thiab cov weldability thiab txheej adhesion yog qhov zoo .
Alloy Rot-Dip Galvanizing (GA, Galvannealed)
Xws li: Zinc-hlau alloy (muaj 10% ~ 15% hlau) .
Cov txheej txheem: Tom qab kub-dip Galvanizing, txheej yog tag nrho cov kev ua kom siab los ntawm kev kho kub siab diffusion {}}
Nta: cov txheej yog denser, nrog rau kev ua haujlwm corrosion, weldability, haum rau lub tshuab hluav taws xob sab nrauv .
Yuav ua li cas paub qhov txawv ga los ntawm dog DN-Fe Txheej?
GA: Qhov saum npoo yog grey thiab tsis muaj xim hlau luster luster (rho tawm tshwj xeeb);
DNCEN DN-FE: Cov saum npoo yog qhov ci dua thiab khaws cov xim hlau ntawm ib co zinc
Dab tsi yog qhov sib txawv ntawm zinc-hlau alloy txheej (ga) thiab ntshiab zinc txheej (GI)?

Nta |
Zinc-Hlau Alloy Txheej (GA) |
Ntshiab zinc txheej (GI, xws li SGCC) |
|
Txheej Txheej Muaj pes tsawg |
ZN-Fe Alloy (Hlau Cross 8-12%) |
Ntshiab zinc (zn ntau dua los yog sib npaug rau 99%) |
|
Kev tshwm sim |
Off-dawb, tsis muaj zinc paj, cov nplaim hluav taws xob |
Nyiaj dawb, nrog zinc paj (tuaj yeem tswj tau tsis muaj zinc paj) |
|
Corrosion Kuj |
Zoo heev (ntom alloy txheej, pitting resistance) |
Zoo (zinc txheej fij rau kev tiv thaiv anode) |
|
Hwj txwv |
Zoo heev (Ntev electrode lub neej thaum tsis kam mus Vuam) |
General (Zinc Txheej yog qhov yooj yim rau kev ua raws li electrode) |
|
Xim nplaum |
Zoo heev (cov nplaim cov qauv tswj cov xim nkag) |
Phosphaating pretreatment yog yuav tsum tau |
|
Muaj zog |
Zoo (siab dua hardness, me ntsis qis dua ducility) |
Zoo heev (ntshiab zinc txheej yog softer) |
|
Cov Kev Siv Raug Raug |
Cov khoom siv hluav taws xob, cov khoom siv hauv tsev siab, ntu uas yuav tsum tau tshuaj tsuag |
Kev tsim kho, cov khoom siv hauv tsev, cov qauv txheej txheem |
Yuav Zinc-Hlau Alloy Txheej xeb?
Nws yuav xeb, tab sis ntawm ib tug ntau qeeb qeeb tshaj li qub hlau {}} thaum lub txheej ua croundide, tiv thaiv lub substrate .
Zinc Hlau Alloy Galvannealed Steel Chev yog siv rau?
Kev Lag Luam Automotive
Use: car doors, fuel tanks, chassis parts (need corrosion resistance + weldability).
Cov Hom Pom Zoo: Ga (Alloyed Zinc Plating) lossis High Zinc Cov Ntsiab Lus Zn-Fe.
Tshuaj Kev Lag Luam Hauv Tsev
Siv: Tub yees txias, tshuab ntxhua khaub ncaws plhaub (xav tau txheej + corrosion tsis kam) .
Cov Hom Pom Zoo: DNS DN-Fe Txheej (tus nqi qis dua) .
Kev Tsim Kho Kev Tsim Kho
Siv: Ru tsev, phab ntsa (xav tau huab cua tsis kam) .
Pom zoo hom: Fuab txheej ZN-FE lossis GI (ntshiab zinc)
