Global Coatings Network News: Ship coating construction method: roller coating method
Ship coating construction method: roller coating method This type of paint construction method refers to painting with a roller soaked in paint.
The roller should not be stained with too much paint.
The principle is that the paint does not overflow on both sides of the roller.
The roller should not be rolled too fast when painting.
The roller should be rolled slowly up and down and left and right.
Special attention should be paid to rough surfaces and welds.
Paint brushes should be used to make up the corners.
.
The roller coating method is more efficient and is used when painting a large area, but the quick-drying coating cannot be used by the roller coating method.

Ship coating construction method: brushing method
Ship coating construction method: brushing method As the name implies, it refers to the staggered vertical and horizontal painting on the surface of the component with a paint brush.
Brushing has a strong penetrating power, which can make the paint penetrate into the pores and gaps.
When there is moisture on the surface of the steel plate, the brushing can squeeze out the water, so that the paint really adheres to the component.
In addition, the brushing also saves coating.
However, the brushing method has low efficiency and is only used for repainting small areas, corners and individual places.

Ship coating construction method: airless spraying method
Ship coating construction method: airless spraying methodThis high-tech paint construction method refers to spraying the paint with high pressure, the paint is forced to atomize at the nozzle outlet, and sprayed on the surface of the coated object to form a paint film.
Compared with the spraying method, when using airless spraying, the paint is less scattered, the efficiency is high, and a thicker paint film can be applied, so it is especially suitable for large-area construction applications.
However, when airless spraying is used, there are higher technical requirements for labor, and fire prevention should also be paid attention to.
At present, almost all shipyards use this method when painting large areas.

Ship coating construction method: spraying method
Ship coating construction method: spraying methodThe spraying method uses compressed air with a pressure of 3-5 Pa to atomize the paint and spray it on the surface of the coated object to form a paint film.
When spraying, the nozzle should be perpendicular to the surface to be coated, and it should move up and down in parallel without swinging.
When using the spraying method, pay special attention to keeping the painted surface very clean and dry, otherwise the adhesion of the paint will be reduced, the paint will be scattered and the solvent will evaporate due to the compressed air, and special attention must be paid to sparks.
The spraying method has high efficiency and is suitable for large-area painting, but the scattering of the paint will cause part of the paint loss.

Regardless of which coating construction method is used for the construction of ship surface coatings, it is necessary to pay attention to the two factors of construction quality and cost saving.
However, at present, large shipyards use airless spraying method in surface coating construction, which not only has high work efficiency.
, And it is not easy to cause paint loss.
