Air-Free Filling and Storage of Cartridges (Airfreeness)

Adhesive bonding processes can be severely compromised by the presence of air inclusions in the bead and by air-induced system elasticities during stop-and-go operations. Ensuring that a cartridge is filled in an air-free manner, and remains air-free during storage, is essential to avoid these effects. The optimization of maintaining long-term high-quality material, even when stored for extended periods, begins with the correct filling process and piston setting for storage and transportation.

Introduction into mixing technology

As already mentioned above, 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.

Parameters to quantify mixing efficiency of static mixers

Depending on the material to mix and the pre-defined application, different mixer characteristics are of particular importance. This chapter focuses on characteristics which describe the properties of the mixer itself (mixer specific characteristics) rather than the application system as a whole (system specific characteristics).

Influence of rheology on mixing behavior in static mixers

When selecting the optimum static mixer, the rheological properties of the starting components and their mixing ratio play an important role. In particular, highly viscous materials with a high proportion of fillers often have a pronounced non-Newtonian behavior. Therefore, a good understanding of the rheological behavior of the components to be mixed is important.

Comparison of static and dynamic mixing systems

For mixing 2K materials, the use of static mixers is generally the preferred choice, as they are simple in design, easy to use and relatively inexpensive. In some cases, however, static mixers do not provide the required mixing performance. Dynamic mixers offer an alternative solution for applications where either very high mixing quality or a solution for rheological demanding materials is required.

Numerical Flow Simulation of mixers

Flow simulations or CFD (Computational fluid dynamics) is an established procedure to analyze and solve problems that involve fluid flows with the help of computers. With this method it is possible to examine the internal or external flow field of a product virtually before a first prototype has been produced.
