Diesel engine repair and repair paint is used for maintenance to maximize the service life of the ship's interior, exterior and various equipment.

And as far as possible to reduce the bottom sea creatures.

To reduce ship resistance. Therefore, ships in operation should develop and fully implement a long-term, preventive maintenance plan, which includes regular flushing, repainting and oiling after a period of time.

The surface treatment of components before painting:

(1) When the shipyard is docked for repairs, first use high-pressure fresh water to wash off the salt on the hull due to seawater, and then use sandblasting (or shot blasting, commonly known as "sanding") to remove the rust. After the paint representative, the ship’s maintenance representative or the ship’s inspection and acceptance, the surface of the hull can be painted after it is deemed to meet the requirements;

(2) In places where sandblasting is not possible or not worthy of sandblasting (small area), sanding and shoveling can be used to remove rust.

The shovel uses a rust removal hammer, a shovel brush, a wire brush, and a manual method, while mechanical polishing usually uses pneumatic tools, such as pneumatic hammers, grinding wheels, and rotating metal parts, to remove rust on the surface of the component. After rust removal, use it. Compressed air blows away the dust on the surface, it is better to rinse it with fresh water once
