The first of a three-part series on static mixing, this article focuses on the different mixing principles in laminar mixing and the typical mixer geometries derived from them.
Adhesives are currently becoming increasingly important in a wide variety of applications in the medical, industrial, and health care industries. Two-component adhesives are being used more and more because of their special properties, and static mixers are the most frequent choice of device for mixing the two-component material before application.
The advantage of using static mixers is they mix two-component materials consistently regardless of who is operating them. This means reproducible mixing outcomes and high reliability since they contain no moving parts. The first key factor when it comes to achieving a high level of efficiency is the mixer design and mixing method. However, the interaction between the mixer itself and the rheological properties of the material, the specified mixing ratio, and the viscosity ratio of the individual components must also be taken into account.
