Embodiment Construction
[0031] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0032] Such as figure 1 with figure 2 As shown, the composite sound-insulating wall panel used for the division of the ship cabin in this embodiment includes a lower panel 6, a rock wool layer 5 is arranged on the upper part of the lower panel 6, and a micro-perforated plate 4 is arranged at a distance above the rock wool layer 5. A glass wool layer 2 is installed above the perforated plate 4, and an upper panel 1 is installed on the top surface of the glass wool layer 2. The upper panel 1 is parallel to the lower panel 6, and side panels are welded on both sides of the upper panel 1 and the lower panel 6 respectively. 7. At the same time, both sides of the rock wool layer 5 and the glass wool layer 2 are bonded to the side panel 7, and the two sides of the micro-perforated plate 4 are welded to the side panel 7; the top of the rock wool...
