Embodiment
[0031] like Figure 1 to Figure 4 As shown in the figure, a manufacturing process for filling foam in the material transportation holes of LNG ships, the dimensions of the transportation holes are 1400mm long * 1100mm wide * 800mm high, including the following steps:
[0032] 1) Divide the blank 1 for filling the transport holes into 3 rectangular foam boards 2 equally along the height of the size of the plugging foam board 8 that can block the transport holes prepared in the machine tool;
[0033] A foam board capable of blocking the transport hole, the length is greater than 1400mm and the width is greater than 1100mm.
[0034] A foam board capable of blocking the transport hole, the length is not more than 1410mm and the width is not more than 1110mm.
[0035] Because it is a foam material, the texture is relatively soft, and the foam board with a larger length and width can be used for interference fit to prevent displacement in the height direction.
[0036] The height...

Abstract
The invention discloses a manufacturing process for filling foam for material transport holes of LNG ships. The size of the transport holes is 1400mm long*1100mm wide*800mm high. The height of the foam board used to fill the transportation holes is divided into 3 rectangular foam boards and prepared in a machine tool with limited size. There are through holes and the punching positions and sizes of the three cuboid foam boards are exactly the same. A compression molding tool for pressing is prepared, and the three rectangular parallelepiped foam boards are placed in the compression molding tool for pressing to form an integral plugging foam. plate. By adopting the design scheme of the present invention, the plugging foam board used for sealing the transportation holes of the LNG transport cabin can be prepared. The existing foam board machine tool cannot directly produce such a large size foam board, so it needs to be prepared in parts.
Description
technical field [0001] The invention relates to an LNG preparation process, in particular to a preparation process of LNG ship material transportation hole filling foam. Background technique [0002] The LNG ship is a special ship that transports liquefied gas at a low temperature of minus 163 degrees Celsius. At present, only 13 shipyards in the United States, China, Japan, South Korea and a few countries in Europe can build it. In the construction design of the ship, the main consideration is given. The factors are the materials that can adapt to the low temperature medium, and the treatment of volatile or flammable substances. In terms of materials, our company mainly uses reinforced polyurethane foam as the insulating material. The foam that needs to be filled in the material transportation holes in the entire storage bin has many problems to be solved in the production process. Only by constantly updating the processing technology in production can the problems that ari...
