[0060] It should be noted that first, the polypropylene hollow plate itself has a certain flexibility and elasticity, and the molecular chain can be deformed when subjected to vibration or impact, absorbing and dispersing part of the energy. At the same time, the hollow structure of the hollow plate can play a buffering and isolating role, reducing the propagation of vibration waves inside the plate material and improving the anti-vibration buffering performance. Secondly, the structure made of polypropylene hollow plate has a relatively light weight, which can reduce the transportation cost in the packaging and transportation process, and is also convenient to carry and operate. Moreover, the material of the hollow plate is relatively soft, which is not easy to cause harm to the operator during disassembly, and also will not damage other articles like some hard materials. Finally, the polypropylene material has good chemical corrosion resistance and can resist the corrosion of various chemicals, so that the application can adapt to various chemical pollution that may be encountered in the marine process, ensure that the application can maintain stable performance for a long time in the high-temperature and high-humidity marine environment, and will not reduce the buffering and protection effect due to the corrosion of chemicals; At the same time, the hollow plate can be added with a buffering structure according to needs, for example, a honeycomb plate, wherein the buffering structure includes but is not limited to the above structure.
