Spherical floats are essential equipment for deep-sea exploration and operations. Their key components include solid buoyancy materials. These materials, with their low density, high strength, and corrosion resistance, play an irreplaceable role in deep-sea floats and other deep-sea equipment.
Spherical floats are devices that maintain stable buoyancy in deep-sea environments. They are typically made of lightweight, pressure-resistant composite materials and filled with solid buoyancy materials to ensure stable buoyancy in the high-pressure, high-salinity, and low-light environments of the deep sea. Deep-sea floats not only provide buoyancy for deep-sea research equipment but can also serve as deep-sea instrument chambers, carrying various scientific instruments and equipment for deep-sea exploration and experiments.
Spherical floats come in various types depending on their material, purpose, and specifications. For example, deep-sea glass floats are made of glass, offering extremely high compressive strength and transparency; others are made of materials such as plastic and polyurethane, offering advantages such as low cost and ease of processing. Furthermore, the diameter, buoyancy, and other specifications of deep-sea floats can be customized to meet specific needs.
