The human eye can distinguish even the most subtle color differentials. Because the eye is such a discriminating audience, the act of mixing color into a melt stream can be an extremely delicate process.  Even a slight alteration can be detected by the consumer’s eye, even if it’s only a subconscious awareness.  Take a store chain like Target, for instance.  Everything in their stores is the exact same shade of red.  If everything was just a little off in the exact shade of red, the whole thing would look unprofessional.  Static mixers can help ensure that your products will look professional and consistent every time.

The SIDD

The SIDD, which stands for Special Introduction and Distribution Device is specially made to introduce and mix colorants in a melt stream.  Six cylindrical and equal sized pipes that are nested around the axis of the pipe each contain a mixer.  When the additive is introduced, it enters at the top of a cone and flows over the cone before it enters one of these six cylinders.

Viscosity and Pressure Drop

Because polymers are sensitive to shear forces, their viscosity depends on the shear rate that they are exposed to.  Fortunately, Komax’s static mixers create the best possible outcomes.  Using static mixing, the coloring process in a melt stream can be done with a minimal drop in pressure, and the viscosity will be consistent throughout the entire manufacturing procedure.

While color may be a difficult part of the manufacturing process to get exactly right, the Komax static mixers can help make sure that it will be done perfectly every time.
