Abstract
A method for modifying a fine particle dispersion liquid has excellent dispersibility and dispersion stability. In this method for modifying a fine particle dispersion liquid having improved fine particle dispersibility, impurities included in an agglomeration of fine particles contained in the fine particle dispersion liquid are released into the dispersion liquid by applying physical energy to the agglomeration and performing dispersion processing for dispersion into particles that are smaller than the agglomeration of fine particles. The impurities are removed from the dispersion liquid by means of a removal unit provided with a filtration membrane before reagglomeration is caused by the impurities.
Claims20
A method for reforming a fine particle dispersion solution, wherein
- in the method for reforming the fine particle dispersion solution with which dispersion property of the fine particles is enhanced,
- a physical energy is applied to an aggregate of the fine particles included in the fine particle dispersion solution thereby carrying out a dispersion process to disperse the aggregate of the fine particles to smaller particles than the said aggregate of the fine particles, thereby discharging impurities having been included in the aggregate into the dispersion solution, and
- before re-aggregation by the impurities takes place entirely, a removal process to remove the impurities from the dispersion solution is carried out by a removing unit.
