Abstract:This program is established on the in the basis of our work during "11th five-year plan".In order to realize the mass production of high-performance hollow glass microspheres, our work will mainly focus on the engineering research. This achievement will promote the technology of solid buoyancy material. Our work going smoothly in 2013, the main content is as follows:(1)We deepened the research on the hollow glass microspheres of the density(0.38±0.02)g/cm3.The comparison test indicates that the compression strength of T38 is better than S38, which from the 3M Company has the same density as T38. And the compression strength of T38 is even better than the S38hs, which has the volume collapse of 44.09% at the pressure of 5500 psi, while the volume collapse at 5500psi of T38 is only 33.75%.(2)We also researched on the surface modification of hollow glass microspheres, and provided the reference for the combination of hollow glass microspheres/resin system.(3)We prepared solid buoyancy material by homemade hollow glass microspheres and tested the mechanical behavior.Then we adjusted the formula and preparation process according to the testing results.(4)We also accomplished the sea tests of the solid buoyancy material. The winch test indicates that the pressure-resistance property of solid buoyancy material prepared by homemade hollow glass microspheres satisfy the contract requests. And the comparison test indicates that the pressure-resistance property of solid buoyancy material prepared by homemade hollow glass microspheres can be as well as the solid buoyancy material prepared by imported hollow glass microspheres. The subsurface buoy test indicates that solid buoyancy material prepared by homemade hollow glass microspheres can satisfy long-term deep sea circumstance.
Key words:Hollow glass microspheres,solid buoyancy material
