Sonic methods for preparing suspensions, dispersions or emulsions of non-uniformly agglomerated particles

摘要

IT;B SYNIC METHODS FOR PREPARING SUSPENSIONS, DISPERSONS OR PARTICULAR EMULSONS NOT UNIFORM D A method for preparing a suspension, dispersion or emulsion of uncontaminated particles, including the formation of particles in a liquid medium, in which sonic energy (28, 30) is applied to the liquid medium at the point of contact (12) of the reagents during the particle forming stage to produce the suspension, dispersion or emulsion of non-agglomerated particles. The invention is also directed at a method to prepare a suspension of particles of salt of non-agglomerated pyrithione,comprising the stages of formation of pyrithione salt particles in a liquid medium, in which the sonic energy (28, 30) is applied to the liquid medium during the formation step in order to produce the suspension of non-agglomerated pyrthion salt particles.
