Solid buoyancy material technology is an organic combination of low density and high strength of materials, so that it shows incomparable advantages in the application of Marine technology. Solid buoyancy material is a new type of special Marine engineering material after the traditional cork, buoyancy cylinder, synthetic rubber, synthetic foam, buoyancy ball, glass ball, etc., because of its low density, high compressive strength, low water absorption rate and stability in deep sea operation, good weather resistance, no pollution to the environment and other characteristics, so it is welcomed by the vast number of users of sea-related units at home and abroad.
Another significant feature of the material is that it is machinable and homogeneous, and can be formed arbitrarily. According to the complex shape of the submersible, it can be processed into the required shape and surface by mechanical processing methods such as sawing, planing, turning, grinding and sticking, etc. Compared with the general foam material processing mold forming, it greatly saves cost, and can be polished, installed and assembled on site. Greatly improve the efficiency, to solve the general foam material can only be formed once, can not be processed.
Solid buoyancy materials have replaced traditional buoyancy materials due to their lightweight, pressure-resistant and machinable properties. In deep sea development, it is widely used in various fields such as underwater robot, deep submersible vehicle, submersible marker system, diving bell, underwater harvester, offshore oil exploration and development riser, deep water pipeline laying float, float cable, float ball, umbilical cable float, mooring buoy, acoustic Doppler current profiler (ADCP) platform, etc. It can meet the needs of deep-sea exploration, oil exploitation, deep-sea mining and so on, and has a very broad application prospect.
