What are the benefits of aluminum alloy patrol boats? Convenient in the water level is relatively shallow river application, but also facilitate closer to the island. In addition, the frictional resistance caused by shallow drinking water is less, and the consumption of raw materials is also less, which not only enhances the rationality of the application of patrol boats.

1. Light weight (rationality)

As we all know, aluminum is not only much lighter than steel, but also lighter than glass fiber reinforced plastic. The net weight of the hull is light, and the sailing speed of the same ship shape is faster and faster under the same high horsepower. The light hull design scheme is generally shallow in water, which is convenient for application in rivers with relatively shallow water levels and is also convenient for closer proximity to islands. In addition, drinking shallow water brings less frictional resistance and consumes less material, which not only enhances the application.patrol boatThe rationality.

2. Compressive strength (safety factor)

Although the density of aluminum is lower than that of steel, the hardness is very high, and it is not inferior to heat-resistant cast iron, not to mention the anti-corrosion of glass fiber reinforced plastic. Many people will mistakenly believe that FRP is a kind of steel, but this is not the case. FRP is a laminated glass fiber composite material, which is a composite material composed of resin material and glass fiber.

If the hull is hit with the same force, FRP will prevent corrosion.patrol boatThere are holes in the aluminum alloy patrol boat, which may just be recessed. This is why most of the sailing ships are made of aluminum and steel. If you sail in the glacier, aluminum patrol boats are more security precautions. In fact, it's not just glaciers, but for obstacles that are generally likely to collide, lumber and shipping containers that go down to the water and rise to the sea.

巡逻艇

Everyone will know the story from time to time. The aluminum patrol boat hit the rock and the staff was rescued by safety despite being trapped on the patrol boat for several days. It is also due to the fact that the aluminum patrol boat is not very easy to crack and inundate even if it is damaged and dent, and the aluminum patrol boat is easier to repair. The same stranding wouldn't be so lucky if it appeared on a fiberglass anti-corrosion patrol boat.

3, strong and durable (durability)

According to the characteristics of the material, the wood is perishable, the steel is easy to rust, and the glass fiber reinforced plastic is very easy to absorb moisture and blister. The glass fiber reinforced plastic anti-corrosion surface layer of the patrol boat determines the water resistance and corrosion resistance, because when your glass fiber reinforced plastic anti-corrosion patrol boat accidentally scrapes the latex coat, it should be repaired in time, instead of thinking that it is as simple as a vehicle without some paint.

Aluminum is one of the most easily eroded metals, and the aluminum alloy used in the deep sea is widely used in ships due to its low corrosion. Aluminum alloy without steel and iron, basically does not rust. Natural aluminum will also appear air oxidation, but in the process of air oxidation needs to create a layer of solid aluminum oxide surface, to avoid the following raw materials to produce erosion again. If the use of suitable aluminum alloy and welding rod, standard construction, on time maintenance, an aluminumpatrol boatCan be used for decades.

4. Fire resistance (safety factor)

Fire is a more terrible disaster on the water, there is no one. How to use glass fiber reinforced plastic anti-corrosion or wood to make the hull, once the fire, the fire will spread quickly, and aluminum will not catch fire, remember that aluminum is much higher than 500 degrees to melt.
