The painting of the engine room and pump room is generally divided into two parts. The first part is the bottom part of the iron plate, that is, the bulkhead part, which requires the paint to be rust-proof, oil-proof, easy to clean and decorative, and not easy to be yellowed. Therefore, this part of the paint using conventional coating system, according to the living cabin bulkhead coating package. 2 iron red epoxy coating or alkyd primer, and then painted 2 light-colored alkyd paint, the total thickness of not less than 120μm. Flower iron below the site, that is, the bottom of the tank may accumulate contaminated water, oil, acid lubricants, etc., and not easy to repair and repair, corrosion environment is extremely poor. Billet paint is the main role of anti-corrosion, aesthetics is secondary, requiring oil, water, acid, strong adhesion and so on. Coating program can be carried out in accordance with the ballast tank or tank paint system. Dry film 200μm above the epoxy asphalt coating, pure epoxy coating is the most commonly used. In recent years, due to the application of new technologies in shipbuilding, the first investment in long-term anti-corrosion has been stepped up, reducing the maintenance cycle. In the corrosion of the bottom of the cabin, shipbuilding using thermal spraying on the steel plate zinc (aluminum) technology, after brushing sealing coating, and then coated with epoxy or epoxy asphalt coating, anti-corrosion life greatly extended. For bulkheads, with the use of solvent-free or water-based coatings, a green paint that is nontoxic and solvent-volatile will be used step by step.
