The Dispersion Process
The most important function of the dissolver is the incorporation of solids into liquids. During this dispersion process, three individual steps are performed at the same time:
- Wetting of the surface of the solid particles by the fluid components of the millbase
- Mechanical break down of solid particles associated with each other (agglomerates and aggregates) to form smaller particles
- Stabilization of smaller particles generated during the dispersion process against reagglomeration
The application of a dissolver for high‒speed dispersion differs considerably to stirring and mixing where low speeds and special tools are generally used. A high‒speed dissolver is highly efficient and in many cases all that is needed to achieve the required dispersion result. If however, a finer dispersion result is desired, dispersion becomes a two step process, with the dissolver used for pre‒dispersion, followed by further milling in a bead or basket mill.
Applications for dissolvers include:
- Dyestuffs and varnishes
- Pigments and additives
- Printing inks
- Chemistry
- Plastics
- Construction chemistry
- Electronics
- Adhesives
- Coatings
- Pharmacy and cosmetics
- Microbiology
- Agrochemicals
