Ocean is a treasure trove of resources and energy, especially deep-sea fields. Currently, deep-sea exploration, development mainly in diving technology, the use of submersible, underwater robots in the deep sea observation, measurement, sampling, install the necessary instruments and facilities, underwater operations. High strength solid buoyant material is an important part of modern diving technology, to ensure the buoyancy of submersible, submersible increased payload, reduce its dimensions, has an important role.
With increasing dive depth, pressure increased dramatically deteriorating environmental conditions, so the sharp increase diving solid buoyant material performance requirements, especially in terms of compressive strength.Generally, improving the compressive strength of the foam density increases often result. But for buoyancy material, density is a very important performance index, which directly affects the buoyancy materials, namely payload capacity.It means lower density increases buoyancy, increased excessive or even lose buoyancy. Thus, advanced solid buoyancy material should be both light and strong, i.e., maintaining a low density, the substantial increase in the compressive strength.Advanced solid buoyant material preparation technology, mainly for the United States, Russia and other countries to master the material density is generally in 0.4 ~ 0.6g / cm3, compressive strength at 40 ~ 100MPa.While in the field of research has been carried out for many years, but dive with solid buoyancy material properties are also poor, heavily dependent on imports. Factors behind this situation are many, the core raw materials – the lack of high-performance hollow glass microspheres is a key factor.
