With the continuous deepening of deep-sea scientific research and the increasing demand for Marine resource development, the requirements for floating materials are becoming increasingly strict. Epoxy-based glass microsphere solid buoyancy materials have stood out with their outstanding performance and become the new favorite of subsea lander buoyancy.
Epoxy-based glass microsphere solid buoyancy material, as the name suggests, is a kind of composite material made by uniformly dispersing and curing tiny and uniform glass microspheres in epoxy resin through a special process. The excellent buoyancy performance of this material is mainly attributed to the following aspects:
1. High specific strength and specific stiffness: As a lightweight filler, glass microspheres can significantly reduce the density of the material while maintaining high strength and stiffness, enabling the float to withstand the tremendous pressure of the deep-sea environment while reducing its weight.
2. Excellent corrosion resistance: The epoxy resin matrix has good chemical stability, effectively resisting salt in seawater, microbial erosion and ultraviolet radiation, ensuring the reliability of the float for long-term use.
3. Excellent thermal insulation performance: In deep-sea environments with large temperature differences, materials need to have good thermal insulation performance to maintain a stable operating temperature for internal equipment. The microporous structure and low thermal conductivity in epoxy-based glass microsphere materials make them ideal insulating materials.
4. Strong designability: By adjusting the particle size, content of glass microspheres and the type of epoxy resin, the density, strength and buoyancy of the material can be flexibly adjusted to meet the requirements of different application scenarios.
