I have been working on particulate design(powder surface modification, encapsulation, microgranulation, etc) by a dry impact blending method since 1987.
The dry impact blending method is composed of two step blending
processes.
The first step is the blending process for
preparation of an interactive mixture.
The second step is the mechanical impact blending
process for preparation of composites
and capsules.
The composites and capsules are capable of improving and controlling the powder properties, such as catalytic activity, wettability, electrical properties, electronic properties, optical properties, rheological properties and so on.
The concept of microfabrication on powder surfaces can be applied in many industrial fields; e.g. in cosmetics, pharmaceuticals, foods, copy toners, paints, pigments, ceramics, cements, inks, detergents, dental materials, metallurgy. etc.
