Case study – R&D study of the influence of mechanical stresses on airgel powders
Sector: Construction
Customer type: Group
Service contact: R&D
The Customer wishes to improve its process for preparing powders airgel for applications in the building sector and called on Rheonis to study the impact of the mechanical constraints imposed by its process on its powders.
Instrumental simulation of process constraints for optimization
In response to this request, RHEONIS implemented its know-how in physical measurement techniques to simulate compressive stresses and mixed representative of the process on different grain size sections of airgel powders
The stages of the study were therefore as follows:
- Adjustment of instrumental protocols on powder cell
- Quantification of the behaviors of different particle size cuts
- Interpretation of results with regard to customer data
- Operational recommendations
Intervention System Gauge
Optimize the application properties of the material/process couple
The actions fueled the Customer's thoughts and facilitated the resolution of the problem. Ways of improving the process were also outlined. The data exploitation parameters were able to be integrated by the Customer into its test procedures.
The advantages of instrumental simulation of mechanical stresses
Degradation controlled by mechanical stress in mixture
Compressibility and air permeability
Low material consumption
