A damping plate installation process on a ship

Abstract

The invention relates to an installation technology of a damping board on a ship. The installation technology comprises the following steps that deoiling and polishing derusting are carried out on the metal surface of a laid base body; the damping board is cut to be of a designed specification; damping glue and fastening nails are mixed and stirred according to the volume ratio of 20:1 to 10:1, each fastening nail is a regular tetrahedron, and the height of each fastening nail is 0.5-0.6 times of the thickness of the damping board; the damping glue mixed with the fastening nails is evenly sprayed on the metal surface of the laid base body and the pasting face of the damping board, and the damping glue with the fastening nails is stored for 5 to 10 minutes to form a glue film; the damping board is located relative to the metal surface of the laid base body and pasted on the metal surface of the laid base body; the surface of the damping board after pasting is knocked, so that the lower planes of the fastening nails are pasted on the metal surface of the laid base body, and the pointed end of each fastening nail is embedded in the damping board. The installation technology has the advantages that the installation technology is simple and quick, pasting can be completed in one time, the board can be installed in place through only one time of polishing and gluing of the board, and installation cost is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of ship noise reduction and shock absorption, and in particular relates to a process for installing a damping plate on a ship. Background technique [0002] At present, as the requirements for humanization are getting higher and higher, the requirements for shock and noise reduction of ships are getting higher and higher, especially for official ships, the noise standards in their living areas will be higher. For this reason, ships, especially official ships, usually use paint-type damping materials to reduce noise on the base steel plate. The paint-type damping materials are composed of an inner damping layer and an outer constraining layer. The group paint is mixed and prepared on site according to a certain ratio; the constraining layer is prepared by mixing and preparing Group A paint and Group B paint on site according to a certain ratio. After preparation, the damping layer is manually applied on the ...

Problems solved by technology

[0004] Recently, there has been a trend in the market to use damping plates for shock absorption and noise reduction, and it has been widely used in the automotive field. However, since the vibration of ships sailing is much greater than that of vehicles, damping plates are easily glued on ships. There are defects such as low firmness and easy falling off, so it has not been able to be widely used
