Abstract Dry particle coating processes are of key importance for creating functionalized materials. By a change in surface structure, initiated during coating, property and thus functionalization can be achieved. This study introduces an innovative approach employing 3D X-ray micro-computed tomography (micro-CT) to characterize coated particles, consisting spherical alumina particles (d50 = 45.64 μm), called hosts, surrounded by polystyrene 3.5 guests. The formed structures,...
In this study, the blocking filtration laws introduced by Hermans and Bredée are applied to evaluate filter aid data. A model system is utilized for experiments, consisting of barium sulphate as impurity diatomaceous earth aid. Based on analysis data, relevant process initially identified cake separation so-called missing law sulphate. The results substantiated with X-ray microscopy monitor incorporation fine particles in structure. They demonstrate that characterised both depth migration...
During the mechano-fusion process for dry particle coating, (hetero)-aggregates are formed consisting of host particles coated by smaller guest particles. this process, latter exposed to intense particle–particle interactions and particle–wall impacts, which lead deformation their original shape. These deformations on nano- microscale can heavily influence effective macroscopic properties resulting We present a method quantification shape based measurements acquired atomic force microscopy...
This study presents a new approach in the quantification of deposited amount impurity inside filter cake made up aid material. For this purpose, three-dimensional imaging by X-ray tomography is applied. Based on attenuation properties, model system consisting kieselguhr as and barium sulphate chosen. Due to particle size being smaller than spatial resolution measuring setup, calibration necessary gain insight into subvoxel information. A so-called phantom similar material composition...
