Powder Incorporation in Viscous Liquid

Background

Resodyn Acoustic Mixers’ second generation technology, LabRAM II, provides up to I kg payload capacity and  advanced control features. Virtually any combination of liquids, powders, pastes, and gases can be processed faster, better, more efficiently, and more productively using the LabRAM II bench-top mixing systems and accessories.

Polymer-Powder Blending

Many polymer based materials require the addition of dry materials such as powders for performance or coloration.

To illustrate dry powder incorporation in a viscous liquid, colored chalk powder was blended with corn syrup.

The image on the left shows the starting materials and the image on the right shows the materials after processing.

The starting materials were 230 grams of corn syrup and 2.5 grams of powdered chalk. The mixing was performed at 20° C with the corn syrup exhibiting a viscosity of 2,100 cP. The materials were blended using the LabRAM IITM mixer.

After only 8 seconds of mixing and 9 minutes of processing under vacuum to degas the mixed material, the two ingredients were thoroughly blended and degassed with the chalk fully dispersed within the corn syrup.

The use of RAM technology is well suited for dispersion of solids into polymers.
