Galvanized hlau
Galvanized steel yog carbon hlau uas tau coated nrog zinc txheej tiv thaiv corrosion. Cov zinc txheej tsim cov ntaub thaiv lub cev uas thaiv cov dej noo, oxygen, thiab cov tshuaj lom neeg los ntawm kev ncav cuag cov hlau. Qhov tseem ceeb tshaj, zinc muab kev tiv thaiv kev txi: thaum muaj kev puas tsuaj tshwm sim, zinc corrodes ua ntej, tiv thaiv xeb los ntawm kev tsim ntawm lub hauv paus hlau.
Galvanization yog ib txwm ua tiav los ntawm kev kub -dip processing. Cov sawb hlau hla dhau los ntawm zinc molten ntawm kwv yees li 450 degree, tsim cov txheej zinc-hlau alloy txheej uas khi nruj rau cov hlau substrate. Cov qauv no tsim cov txheej txheem zoo adhesion thiab ntev -lub sij hawm durability.
Cov khoom no ua rau cov hlau galvanized tseem ceeb hauv kev tsim kho, kev thauj mus los, lub zog, kev ua liaj ua teb, thiab kev tsim khoom siv. Nyob rau hauv qeb no,DX51D galvanized steel kaujyog qhov feem ntau siv los ua qib thoob ntiaj teb.
Dab tsi txiav txim siab lub neej kev pab cuam ntawm DX51D Galvanized Steel?
Lub neej kev pab cuam ntawm DX51D galvanized steel kauj nyob ntawm ntau yam cuam tshuam:
Zinc txheej thickness (Z60-Z275)
- Environmental raug (humidity, ntsev, kuab paug)
- Mechanical hnav thiab nto puas
- Installation thiab txij nkawm zoo
DX51D tshuaj muaj pes tsawg leeg
| Element | C | Mn | P | S | Ti |
|---|---|---|---|---|---|
| Max % | 0.12 | 0.60 | 0.10 | 0.045 | 0.30 |
DX51D Mechanical Properties
| Khoom | Tus nqi |
|---|---|
| Yield zog | Ntau dua lossis sib npaug li 140 MPa |
| Tensile zog | 270-500 MPa |
| Elongation A80 | Ntau dua lossis sib npaug li 22% |
Cov qauv ruaj khov no tso cai rau DX51D los txhawb cov zinc txheej tuab yam tsis muaj kev tawg lossis tev tawm thaum tsim.
Corrosion Performance nyob rau hauv txawv ib puag ncig
| Ib puag ncig | Hom Zinc | Cia siab rau Kev Pabcuam Lub Neej |
|---|---|---|
| Hauv tsev qhuav | Z60–Z80 | 15-20 xyoo |
| Nroog sab nraum zoov | Z120–Z160 | 20-25 xyoo |
| Ntug hiav txwv / industrial | Z180–Z275 | 25–{1}} xyoo |
DX51D ua ke nrog cov zinc txheej txheej zoo muab kev kwv yees thiab ntev - kev tiv thaiv ntev nyob rau ntau qhov kev nyab xeeb.
