Project outline:

Research into granular materials that can be used to increase the collision safety of ships is being continued in this project. Expanded glass granules (Poraver) have proven to be particularly suitable due to their chemical and physical properties. However, the abrasive behavior of the Poraver particles under dynamic loading is a disadvantage for the application under investigation.

One way to overcome these problems is to coat the particles in the fluidized bed spray granulation process. The coating material is subject to the same requirements in terms of environmental friendliness, density, etc. as the granules themselves.
