Problems solved by technology

However, the performance of domestic deep-water buoyancy materials is still in the development stage compared with foreign countries. Compared with foreign products of the same grade, there are still problems such as high density, low strength, high water absorption and low production efficiency, resulting in the production of deep-water buoyancy materials. The net buoyancy provided is insufficient, the size of the buoyancy structure is too large, and the long-term use performance is unstable, which seriously affects the application of buoyancy materials on deep-sea submersibles and hinders the submersible from exploring deeper sea areas
