“…The mechanical properties of the composites are obviously improved by coating with KH-550. With the increasing dose of KH-550, the mechanical At a low spouting gas velocity, the fluidization of particles in the bed is unstable, which leads to the aggravation of particle agglomeration growth, resulting in a large particle size after coating [23]. Due to the poor N-WPCB surface modification process, the mechanical properties of the composites were low.…”

Nonmetallic materials recycled from waste printed circuit boards (N-WPCBs) were modified by coating KH-550 in a spout-fluid bed. To improve the effect of the modification, PP particles were used to enhance the fluidization quality of the N-WPCB particles in the coating modification. Then, the modified N-WPCBs were used as fillers to fabricate PP/N-WPCB composites. The method of coating in a spout-fluid bed with PP particles enhanced fluidization and showed the best modification effect compared to other coating methods. The FT-IR and SEM results demonstrated that interfacial bonding between N-WPCBs and PP could be enhanced by modified N-WPCBs, which improved the mechanical properties of the composites. When the mass ratio of PP to N-WPCBs is 100:75 and the dose of KH-550 is 4 phr, the flexural strength, tensile strength, and impact strength of the composites increase by 16.60%, 23.22%, and 23.64%, respectively. This would realize the high-value utilization of N-WPCBs with coating modification in the spout-fluid bed.

“…Agglomeration of soft porous primary particles consists of various micro-scale mechanisms. Monte Carlo model from Singh and Tsotsas [1], incorporated with most of the relevant micro-scale mechanisms, is adapted in the present work. These micro-scale mechanisms with the MC algorithm are self-programmed in MATLAB.…”

“…The type of solid substrate is critical in determining the kinetics of the SFB agglomeration process. In general, droplet aging in SFB agglomeration of non-porous hard primary particles is solely due to convective drying of the deposited droplets [1][2][3][4][5][6]. In the case of porous hard primary particles, the aging process of the deposited liquid layer is additionally caused due to penetration (imbibition) into the pores of the substrate [7,8].…”

“…It is also assumed that the water is uniformly distributed in the puddle space, with the area of the puddle equal to the droplet cap area and the height remaining unchanged. For hard porous and non-porous solid substrates, the kinetics is modeled by the decrease in droplet height [1][2][3][4][5]. For amorphous solids, the kinetics is controlled by the amount of water evaporated from the puddle [9].…”

Type of solid substrate plays a critical role in determining the kinetics of the spray fluidized bed (SFB) agglomeration process. In the case of soft (also porous) primary particles, droplet aging is due to imbibition and drying. The surface properties of substrate also change due to imbibition. The focus of the present work is to simulate the agglomeration of the spray-dried milk powder using Monte Carlo (MC) method coupled with a drying-imbibition model. In order to extract the morphology of the formed agglomerates, an aggregation model is employed. The transient growth of soft porous particles is depicted using the enhanced MC model.
