powders surface energy can be optimally functionalized
Suspensions of powdery substances and fluids are used in a multitude of technical processes and products. Fine powders tend to clump together, while coarse powders tend to sediment. These segregation processes depend on the powder’s surface energy and its interaction with the fluid.
Who has never struggled to dissolve dark cocoa powder evenly in cold milk? Not only chocolate lovers are familiar with this problem, technologists are as well. Corresponding examples of industrial applications are:
• Dispersions in food and cosmetics as well as paints and varnishes
• Powdery additives and fillers in composite materials
• Production and solution optimization of pharmaceutical granulates
Using RP plasma system, powders can be modified in one continuous process and their surface energy can be optimally functionalized to form stable suspensions.
It is generally possible to turn over several kg per hour.
The Piezo plasma can be applied to modify highly sensitive powders in food technology and the pharmaceutical industry within a closed and thus ultrapure batch process. Alternatively, discharge can be coupled into a continuous throughput reactor. Ultrapure processes can reliably be conducted that way.
