Agglomération de poudres ultrafines : causes et technologies de dispersion
Vous passez des semaines à optimiser le processus de broyage. Le D50 semble parfait sur l'analyseur. Une semaine plus tard, votre client lance un lot et vous contacte en raison de résultats incohérents. L'agglomération de la poudre en est généralement la cause. Pour les poudres inférieures à 30 μm, les particules ne se comportent pas comme des matériaux massifs. Elles s'agglutinent, forment des grumeaux et perdent leur intégrité.
