Study on the Flow Mixing Results of Revolving Static Mixer Used in Solventless Laminator

Abstract

For solventless lamination, the mixing process of A/B materials adds a significant value to the performances of solventless lamination adhesives. Static mixers are always the main device of the solventless laminator to be used to mix A/B materials. Both design and operation of mixing unit itself has a strong effect on the quality of final product of lamination. In this paper, Fluent software is used to develop the two dimensional models of flow mixing process within the static mixer under different status. One static mixer is revolving during the mixing process, the other one is static during the mixing process. The simulation results show that the result of mixture process within the revolving static mixers is much better than the result of mixture process within the static mixer which did not revolve. Through this simulation and analysis, the revolving static mixer is recommended to be used in the situation where it is strict required for the mixing results, though the structure of revolving static mixer is complicated. This research will supply a good help for the design of solventless laminating machine.
