A static mixer is a device, usually metal or plastic, that is fixed in a pipe or tube to mix whatever liquid passes through it. Its design usually involves separating the flow into streams and forcing them against each other. Popular forms are repeating, opposite spirals, or intertwining flows. They can be used to mix different liquids into one homogeneous liquid, or just ensure an even mix of an already mixed solution. They are often used to mix two component adhesives and sealants. Other applications include wastewater treatment, chemical processing, etc.
