Why should the huge aircraft carrier clean up the bottom of the ship regularly?

Everyone knows that people need maintenance and cars also need, so for the carrier, of course, it is no exception, and it is necessary to regularly clean and maintain. Many people may think that the aircraft carrier is so large, and there are many machines. How to maintain it? What should I maintain?

Because after a long navigation, the bottom of the aircraft carrier will parasitize a large number of marine creatures. These creatures parasitic on the bottom of the ship will increase the weight of the hull, increase the water resistance, and cause the aircraft carrier to slow and increase the fuel consumption.

In fact, no matter what ship, as long as it sails in the water for a period of time, a large number of seaweed will be attached to the ship. There will be many marine creatures such as shellfish and oysters. They will treat the hull as a reef and settle in the house. Long time, the number of these marine creatures is very huge. For some large ships, the marine creatures attached to the bottom of the ship can reach tens of tons, which seriously drags the power of the ship.

In fact, we all think of this incident too complicated. The most important thing that the aircraft carrier needs to maintain cleaning is the bottom of the ship, because the aircraft carrier often drives in the water, and many creatures in the sea will be adsorbed on the bottom of the aircraft carrier. There will be more and more creatures, leading to the damage of the carrier bottom of the carrier, and bring bad consequences.

As long as the microorganisms of the bottom of the ship are cleaned, as long as the creatures of seagrass and shells are cleaned, because the aircraft carrier static in the water for a long time, the seagrass in the water will slowly grow crazy growth against the bottom of the ship. Attracting many shells, and most people of shells know that it will secrete some strong acid substances, and it will corrode the chassis over time.

Because cleaning the bottom of the ship requires a lot of money and labor. Therefore, in this case, people often brush a layer of toxic substance paint on the bottom of the ship, so that there will be no biological adsorption on it, but toxic substances will always be exhausted, so some aircraft carriers need to be cleaned regularly and maintained regularly. It is to re -apply a layer of paint.
