Powder Dispersion with High-Shear Vacuum Expansion: The Technology of the Future

When you savor a richer yogurt, admire a smoother paint finish, or rely on stronger adhesives, there's one thing that ties these diverse products together: exceptional powder dispersion. The way powders are opened up, mixed, and spread out is crucial in determining the quality of the final product.

To get the best results, every tiny powder particle—initially dry and clumped together—needs to be completely separated and evenly enveloped by liquid. Only then can they be stably suspended and uniformly spread throughout the mixture, ensuring a consistent and high-quality end result.

Dispersion: The Heart of Production

Powder dispersion in liquids is often seen as a key process in production—it's complex, technical, and can be quite tricky. Just tossing powders into a liquid won't cut it. Real dispersion demands a carefully orchestrated series of steps:

Separation
Deagglomeration
Complete Wetting
Homogeneous Distribution
Stabilization
Only by executing these steps with precision can we unlock the full potential of the powder’s properties in the final product.

Powder Dispersion: A Universal Requirement

Did you know there are over 100,000 different types of powders used around the world? Surprisingly, very few of them are actually consumed in their dry form. Almost all of them go through a process of dispersion into liquids during production. Each type of powder has its own unique behavior—some push liquids away, while others might react or dissolve—and each one changes the properties of the liquid in its own special way.

Given this variety, dispersion systems need to be flexible. That’s where ystral comes in with their modular machine design, which allows for precise adjustments based on different materials, shear rates, and processing speeds. Their technology strikes a balance between flexibility and the consistency you can rely on.
