Marine-qib aluminium plays lub luag haujlwm tseem ceeb hauv kev tsim cov nkoj ruaj khov, lub teeb yuag muaj peev xwm tiv taus qhov hnyav marine ib puag ncig. Ntawm lawv,5052, 5083, thiab 5086 alloysyog cov nyiam nyob rau hauv lub nkoj lub tsev vim lawv zoo heev corrosion kuj, zoo weldability, thiab impressive zog.
Cov khoom thiab qhov zoo ntawm Marine Qib Aluminium Sheets
Aluminium alloys yog dav siv nyob rau hauv marine kev lag luam vim hais tias ntawm lawv inherent zoo:
Lub teeb:Piv nrog rau cov khoom siv ib txwm muaj xws li steel, aluminium txo qhov hnyav ntawm lub nkoj tag nrho, txhim kho roj efficiency thiab kev ua haujlwm.
Siab zog - rau - Qhov hnyav piv:Cov alloys no muab lub zog zoo dua yam tsis muaj qhov tsim nyog, ua kom lub nkoj ruaj khov thiab kev ncaj ncees.
Corrosion Resistance:Exceptional tsis kam rau seawater corrosion extends lifespan ntawm marine lug thiab txo cov kev xav tau ntawm kev tu.
Ua haujlwm tau zoo:Cov alloys pom zoo weldability, bendability, thiab formability - tseem ceeb rau shipbuilding thiab fabrication txheej txheem.
Kev sib piv ntawm 5052, 5083, thiab 5086 Alloys
Cov lus hauv qab no qhia txog qhov txawv ntawm peb qhov tseem ceeb marine aluminium alloys.

Cov qauv kev coj ua
Txhawm rau kom ua tau zoo thiab ua haujlwm tau zoo, marine- qib aluminium ntawv los ntawmGNEEUa raws li kev lees paub thoob ntiaj teb cov qauv xws li:
ASTM B 209 Cov khoom siv- Txuj Specification rau Aluminium thiab Aluminium -Alloy Sheet thiab Phaj.
ANSI/AWS D1.2- Cov Qauv Vuam Code rau Aluminium.
Cov ntawv thov hauv Boat Building
Vim lawv cov tshuab thiab corrosion-cov khoom tiv taus, cov hlau no tau siv dav hauv ntau yam nkoj:
Hulls thiab Superstructures:Muab cov qauv kev ua haujlwm siab thaum tswj qhov hnyav kom ua tau zoo dua.
Decking:Qhov zoo tshaj plaws rau kev tsim cov uas tsis yog- plam, ruaj khov, thiab corrosion- cov chaw tiv taus.
Ship Containers thiab Tanks:Zoo heev rau cov dej qab zib thiab roj tso tsheb hlau luam vim muaj kev tiv thaiv corrosion zoo dua.
Cov Txheej Txheem Platforms:Siv nyob rau hauv nruj marine platforms thiab ntiav -dej operating systems rau txhim khu kev qha kev ua tau zoo.
Xaiv txoj cai Alloy
Xaiv cov alloy tsim nyog ua kom pom kev ua tau zoo thiab tus nqi ua haujlwm hauv marine engineering daim ntaub ntawv:
5052 Aluminium:Qhov zoo tshaj plaws rau cov khoom uas yuav tsum tau ua ntau zaus thiab khoov thaum tuav lub zog zoo.
5083 Aluminium:Muab qhov tshwj xeeb toughness thiab yog zoo - haum rau siab - kev nyuaj siab marine applications thiab ib puag ncig huab.
5086 Aluminium:Muab qhov sib npaug ntawm lub zog thiab weldability, muab kev tiv thaiv zoo tiv thaiv dej hiav txwv corrosion.
GNEE, yog ib lub tuam txhab txhuas txhuas nyob hauv Suav teb, muab cov nqi zoo tshaj - zoo marine- qib txhuas cov ntawv tsim los ua kom tau raws li cov qauv thoob ntiaj teb rau kev tsim nkoj thiab kev siv sab nrauv. Nrog rau kev tsim khoom siab tshaj plaws thiab kev tswj xyuas nruj, GNEE ua kom txhua lub phaj txhuas xa cov kev ntseeg siab, kev ua tau zoo, thiab ua haujlwm ntev hauv kev xav tau ntawm thaj chaw marine.
