ハルマスカーは船の内部の雑音の海水への伝播
を遮断するために船体外側にそつて設ける散気管
で、本発明はそれの塗布方法に関する。DETAILED DESCRIPTION OF THE INVENTION A hull masker is an air diffuser pipe installed along the outside of a ship's hull to block the propagation of noise inside the ship to seawater, and the present invention relates to a method for applying the same.

る。 A hull masker is an aeration pipe 2 installed at several locations outside the ship 1 from the side plate to the bottom plate, as shown in the side view a and front view b of the ship in Figure 1, and Figure 2 shows a cross section of it in the bow and aft direction. Pipe wall 2 in contact with seawater
Air diffusion holes 2b of 1.2 m/m are drilled at several m/m pitches on the entire surface a. 3 is a cover for reducing navigation resistance. This hull masker also requires an antifouling coating, and in the past, toothpicks or the like were inserted into the coating to prevent the air diffuser holes from being painted over.
However, since there are thousands of diffuser holes and the holes are in close contact with each other as mentioned above, such work requires a considerable amount of man-hours. Therefore, in the present invention, the air diffuser pipe is connected to a compressed air source, and painting is performed while air is blown out from the air diffuser holes. The pressure of this compressed air is preferably around 0.3 kg/cm 2 , and this can be achieved simply by connecting construction compressed air to the air inlet of the hull masker device through a pressure reducing valve. To apply the paint, use an ordinary spray gun with a jetting pressure of 2 to 4 kg/ cm2 .
The ejection from the air diffuser hole 2b continues until the paint dries.
本発明は以上のような極めて簡単な方法により
散気孔の塗りつぶしを防ぐことができるものであ
る。 The present invention can prevent the air diffuser holes from being filled up using the extremely simple method described above.
