Marine Aluminium Phaj yog dab tsi?
A marine aluminium phaj yog qib tshwj xeeb ntawm aluminium alloy daim ntawv tsim tshwj xeeb rau kev tsim khoom hauv nkoj thiab sab nrauv. Tsis zoo li cov qauv kev lag luam txhuas, marine- qib txhuas phaj yuav tsum muaj kev tiv thaiv zoo tshaj plaws rau seawater corrosion, zoo vuam kev ua tau zoo, thiab ntev - lub sij hawm kev ruaj ntseg nyob rau hauv hnyav dej hiav txwv ib puag ncig.
Vim tias txhuas yog lub teeb yuag thiab muaj zog heev, siv nws hauv lub nkoj tsim kom txo tau lub nkoj qhov hnyav, nce ceev, thiab txuag roj. Koj feem ntau yuav pom cov phiaj no siv hauv qab lub nkoj, sab vaj huam sib luag, nkoj nkoj, txoj kev taug kev, lub txaj cav, thiab cov khoom siv loj rau yachts, ferries, thiab nkoj nuv ntses.
Puas yog koj tab tom nrhiav rau daim ntawv pov thawj marine aluminium rau koj lub nkoj? Hu rau GNEE hnub no kom tau txais kev tsocai sai. Peb muab ncaj qha rau thoob ntiaj teb shipbuilders nrog tag nrho cov ntawv pov thawj.

Lus Cim: Cov ntsiab lus ntawm Magnesium (Mg) siab dua, cov hlau alloy muaj zog dua, tab sis nws yuav tsum nruj dua dov thiab tempering tswj kom tsis txhob tawg.
Mechanical Properties
Shipbuilders yuav tsum paub qhov tseeb lub zog txwv ntawm cov hlau ua ntej tsim lub hull. Peb pr
ovide tshwj xeeb marine tempers, feem ntau H116 thiab H321, uas yog engineered los xauv rau hauv cov hlau tus qauv thiab tiv thaiv corrosion los ntawm kev sib kis raws li grain ciam teb.

Yuav xaiv li cas los ntawm hom nkoj
Cov dej sib txawv thiab cov nkoj sib txawv yuav tsum tau xaiv cov khoom tshwj xeeb kom sib npaug kev nyab xeeb thiab nyiaj txiag. Ntawm no yog peb daim ntawv qhia kev siv tau raws li xyoo ntawm kev muab cov chaw nres nkoj.
1. Seawater Ib puag ncig
Kev Siv Hom: Offshore nuv ntses nkoj, khoom kim heev yachts, offshore platforms, thiab dej hiav txwv ferries.
Pom zoo Hull Material:5083-H116los yog 5086-H116.
Pom zoo Sab saum toj Deck: 5754 lossis 6061 (rau cov qauv tsim).
Vim li cas? A 5083 marine aluminium phaj muaj qhov ua haujlwm siab tshaj plaws rau pitting thiab exfoliation corrosion tshwm sim los ntawm cov dej ntsev tsis tu ncua. Nws tseem tuav nws lub zog zoo kawg nkaus tom qab vuam, ua rau lub cev muaj kev nyab xeeb tag nrho tiv thaiv kev cuam tshuam yoj.
2. Ib puag ncig dej ntshiab
Kev Siv Hom: Cov nkoj nuv ntses hauv hiav txwv, pas dej pontoon nkoj, dej ferries, thiab cov khoom siv ua si lom zem.
Khoom siv pom zoo:5052ib 5754.
Vim li cas? Cov pas dej tshiab thiab cov dej ntws tsis muaj cov ntsev ntsev hnyav ntawm dej hiav txwv . 5052 yooj yim rau khoov, raug nqi heev - siv tau, thiab muab ntau tshaj li kev tiv thaiv xeb thiab lub zog rau cov dej no. Koj tsuas yog xav tau 5083 rau cov pob qij txha tseem ceeb yog tias lub nkoj loj.
3. Siab -Speed thiab Patrol Boats
Kev siv ib txwm: Cov nkoj saib xyuas ntug hiav txwv, cov nkoj siab -ceev ceev, thiab cov khoom siv tub rog.
Khoom siv: 5456-H116.
Vim li cas? High- nkoj nrawm ntsib qhov hnyav "slamming loads" (qhov cuam tshuam hnyav ntawm kev sib tsoo nthwv dej ntawm kev kub ceev). 5456 muab lub zog tensile ntau dua thiab muaj zog tshaj 5083, tso cai rau lub nkoj coj hnyav hnyav yam tsis muaj deforming, thaum ua kom lub nkoj lub teeb txaus rau siab - lub cav ceev.

GNEE muab ntxiv - dav marine daim hlau mus txog 2650mm. Xa koj cov phiaj xwm txiav rau peb lossis daim ntawv teev npe loj kom tau txais lub sijhawm tsim khoom.
Txheej txheem ntau lawm
- Melting thiab Casting: Peb yaj siab - purity aluminium ingots thiab ntxiv cov nqi ntawm Magnesium thiab Manganese.
- Kub Rolling: Cov slab tuab yog rhuab thiab nias rau hauv lub phaj muaj zog, ntom.
- Txias Rolling: Rau cov phaj nyias nyias, peb txias yob lawv kom ntaus cov tuab tuab.
- Marine Tempering (Cov kauj ruam tseem ceeb): Peb siv cov kev kho cua sov tshwj xeeb kom ua tiav H116 lossis H321 tempers. Qhov no stabilizes cov qauv hauv cov nplej kom cov hlau tsis tev lossis flake hauv dej hiav txwv.
- Ultrasonic Testing (UT): Peb luam theej duab daim hlau tuab nrog ultrasound kom paub tseeb tias tsis muaj npuas npuas lossis tawg hauv.
- Tension Leveling: Peb ncab daim hlau kom lawv tiaj tus. Cov paib pav ca yog qhov tseem ceeb rau kev sib tw nkoj welding.
- Txiav thiab Ntim: Txiav rau koj qhov ntev npaum li cas thiab ntim tau zoo rau kev thauj mus los hauv hiav txwv.
Kev Tswj Xyuas Zoo thiab Kev Xeem
GNEE Aluminium ua raws li cov qauv ntsuas thoob ntiaj teb nruj, suav nrog ASTM B928 thiab EN 485 Marine Qib. Ua ntej ib daim ntawv pov thawj tawm ntawm peb qhov chaw, nws yuav tsum dhau:
- UT Ultrasonic Flaw Detection: Txheeb xyuas qhov tsis xws luag sab hauv.
- Kev Ntsuas Tshuaj Ntsev: Kev sim rau ntau dua lossis sib npaug li 1000 teev los ua pov thawj dej hiav txwv.
- Mechanical Testing: Txheeb xyuas qhov tensile thiab yield zog nyob rau hauv peb lub lab.
- IGC (Intergranular Corrosion) Test: Xyuas kom xeb yuav tsis nkag mus tob rau hauv cov hlau nplej.
- EXCO (Exfoliation Corrosion) Kev Ntsuas: Ua pov thawj qhov chaw yuav tsis tev tawm hauv cov khaubncaws sab nraud povtseg hauv dej hiav txwv hnyav.
- 100% Dimension Check: Ua kom tuab thiab tiaj tus raws li qhov xav tau ntawm nkoj nkoj.
Tolerance Standards
Thaum tsim ib lub nkoj, precision tseem ceeb. Phem thickness tolerances ntxiv qhov hnyav tsis tsim nyog rau lub nkoj, ua kom qeeb. Tsis zoo flatness ua rau tsis siv neeg vuam tshuab ua tsis tau. Peb tswj kev kam rau siab rau qib A shipbuilding qauv:
| Xyuas yam khoom | Tolerance Range |
| Thickness | ± 0.1 hli rau ± 0.3 hli (nyob ntawm tag nrho cov thickness) |
| Dav | ± 2.0mm txog ± 3.0mm |
| Flatness | Tsawg dua los yog sib npaug li 4 hli ib 'meter' |
| Nto Zoo | Marine Qib A (Tsis muaj kab nrib pleb, tsis muaj roj, tsis muaj qhov ntsuas siab) |
Peb lav nruj thickness kam rau ua kom koj tag nrho cov hlab ntsha hnyav tswj. Hu rau GNEE kom thov peb cov ncauj lus kom ntxaws soj ntsuam zoo thiab cov qauv MTC.
