At present, ships more environmentally friendly aluminum alloy material and technology has become the trend of manufacturing.
Aluminum alloy ship is a steel ship and third material of the ship after ship of FRP, has been widely used in the market and can be vigorously pursued.
Although currently there is not a complete substitute for steel ship and the glass fiber reinforced plastic ship, But whether in the material life of aluminum alloy ship, or in terms of energy conservation and environmental protection, has very strong potential for development.
With the rapid development of shipbuilding industry at home and abroad, marine environmental protection and lightweight and more attention.
This one trend makes shipbuilders turning of aluminum alloy ship.
Compared with the low carbon steel, aluminum alloy can reduce the structure of the ship 50%.
Hull weight, increase the speed of navigation, the fuel consumption is reduced, so the ship on a corresponding reduction in the amount of carbon dioxide emissions, pollution is also reduced.
And the glass fiber reinforced plastic ship in the manufacture and the dismantling process produces a large number of harmful substances, And the traditional glass fiber reinforced plastic material to repair the poor, not easy to be degraded, the environment pollution is very large.
