The core technology of buoyancy modules lies in their low density and high compressive strength. Currently, the mainstream material is solid buoyancy material.
Epoxy-based microsphere solid buoyancy material
Composition: It is made by embedding millions of hollow glass microspheres filled with air as fillers into an epoxy resin matrix and curing it.
Principle: These microspheres are very small and strong, capable of "locking" air inside. Even under immense external pressure, the critical pressure at which the microspheres themselves are compressed or crushed is very high, thus ensuring the overall low density and pressure resistance of the material.
Performance: Different densities (from 0.3 to over 0.7g/cm³) and pressure resistance levels (from several hundred meters to the full ocean depth of 11,000 meters) can be customized based on the type, density, and proportion of the microspheres.
Characteristics: It is currently the most mainstream and reliable deep-sea buoyancy material in terms of performance.
Distributed buoyancy modules are one of the cornerstones of modern deep-sea engineering technology.
A distributed buoyancy module is a buoyancy-providing device applied to deep-sea equipment. Its core concept can be summarized as follows:
Buoyancy module: A component that provides net positive buoyancy, with a density much lower than that of seawater, used to counteract the heavy structural weight and negative buoyancy load of the equipment itself, enabling the entire system to achieve a nearly neutral buoyancy state in water.
Distributed: Unlike traditional designs that concentrate buoyancy materials in one location, the distributed design disperses multiple smaller, standardized buoyancy modules at various key positions of the system.
Deep-sea: Specifically designed and manufactured to withstand the extremely high hydrostatic pressure at depths of several thousand meters.
