After a long sea voyage, the ship will be towed into the dock for maintenance. The most contaminated part is the bottom of the ship. According to different sea conditions and the influence of ocean currents, the bottom of the ship will attach a variety of microorganisms, so regular maintenance is required. What should ship maintenance know? 1. What is the purpose of maintenance? The purpose of ship paint maintenance is to extend the service life of the ship's internal, external and various equipment, and to minimize the adhesion of marine organisms on the bottom of the ship to reduce the ship's navigation resistance. Therefore, the ship should develop and fully implement a long-term, preventive maintenance plan, which includes regular flushing, repainting and other maintenance measures. What are the requirements for ship paint? Ship paint generally requires good decoration, weather resistance, anti-corrosion, sun protection, anti-rust, anti-corrosion, anti-fouling, wear resistance, cold resistance and other properties. 3. What are the weather requirements for ship painting construction? The basic requirements for ship painting construction are: clear weather, no wind, no pollution, and humidity in the air within 90%. 4. How should the surface of the ship be treated? (1) When the shipyard is docked for repair, the salt on the hull shall be washed off with high-pressure fresh water, and then the rust skin and the floating paint skin shall be knocked off by sand blasting method (or shot blasting method, commonly known as "sand beating"). Only after the ship's acceptance can the surface of the hull be painted. (2) In places that cannot be sandblasted or are not worthy of sandblasting (small area), derusting can be carried out by tapping shovel or grinding. The tapping shovel can be operated by derusting hammer, blade brush, wire brush and other tools, while mechanical grinding usually uses pneumatic tools, such as pneumatic hammer, grinding wheel and rotating metal parts, etc. to remove rust on the surface of components. After derusting, compressed air should be used to blow the surface dust and rinse with fresh water. (3) For two-component paint, attention should be paid to its blending ratio, curing time and pot life, and the specific operation should be carried out in accordance with the instructions.
