Talk about the synthesis of organosilicon monomer fluidized bed silicon particle size selection

It is an indisputable fact that the particle size and its distribution have a great influence on the particle size and its distribution! In this forum, there are many forum friends made the discussion. Especially the CSPC, bb88 and dark horse were sent gossip 'synthesis of organosilicon monomer fluidized bed using silica fume particle size (2012.7.23), we from the international advanced level have how far? (2) (2015.02.10). And silica fume particles in particle size and distribution of monomer synthesis of post (2013.08.06), ygq9394 published insightful posts, but these posts, although is very good, but careful analysis, total sense have deficiencies, lack of a rational analysis, did not say clearly fluidization characteristics of silicon particles in fluidized bed exactly and silica fume particles in the particle diameter and distribution relationship, why will be different, it seems the fluidized bed in the silicon powder particles size and distribution of the choice is mysterious, arbitrary and ruleless of. That to make in the monomer synthesis post project technology personnel may don't understand of particles in the fluidized bed particle size and distribution of gas solid fluidized bed flow of the effects and regularity, may also not too cause counterparts on the particle size and distribution of pay attention to and improve the, due to practical production does not seem to occur any problems. To illustrate the fluidized bed particle size and distribution of the relationship, so I wrote below on the synthesis of organosilicon monomer fluidized bed of silicon particles with particle size and distribution of rational analysis and industrial production process on the particle size and distribution of the selection principle, half quantitative and half qualitative discussion, for reference of selection, determination and silica fume improved particle size and distribution in the monomer was synthesized by colleagues. Hope u have to post about!
Classification and fluidization characteristics of fluidized bed particles:
1973 Geldart according to years of particle size of fluidized bed flow characteristics study, the particulate fluidization characteristics and particle average diameter relation into a, B, C and D and they draw table in DP as abscissa, the difference of solid density p p and flow of gas density p g (P P - p g) for longitudinal coordinate chart (see particles of Geldart classification chart below). In order to select the particle size and distribution of the characteristics of the characteristics of its industrialization, the characteristics of the characteristics of the characteristics of the characteristics of the physical or reactive processes are required.
