Hollow Glass Bubble Description
The theory behind using hollow glass bubbles in buoyancy materials involves reducing material density while maintaining or increasing buoyancy. The low density of hollow glass bubbles makes them ideal for reducing weight while preserving buoyancy properties.
Applications
- Underwater cables and pipelines: Provide buoyancy when wrapped around cables or pipelines, reducing weight and easing installation.
- Dredging and mining: Added to equipment to reduce weight and increase buoyancy, improving operational efficiency.
