This invention relates to a base material hollow glass microsphereshes from the wasted coal ash dust of electric power plant . The body of the buoyancy material is formed by epoxide resin hollow spheres, the outside walls of epoxy hollow spheres are intensified, and the space of epoxy hollow spheres are filled with fillers. Its characteristic index by experiment are: specific gravity less than 0.5, high pressure proof, low water absorption after destruction. It is suitable for man underwater vessels. The produtive process is simple and the cost is low. It is able for batch process. |
