percolation ratio
1.By percolation is made the comparison between the EMT, EMTDD and BW theories so as to find that under the condition of low water/oil ratio the work system in this paper is in comformity with the EMT theory.
2.After comparing the results of the experiments, the research choose to wet FAI powder for12 hours by water, then add 0.2mol/l hydrochloric acid solution intothe powder to dip the powder for 2hours, the solvent ratio (hydrochloric acid solution (v): power (w)) is 3:1. Orthogonal experiments are designed to optimize the percolation processes.
