The working principle of the static mixer is to make the fluid in the pipeline flow impact plate element types, increase the velocity gradient of fluid laminar or turbulent and laminar flow is "segmentation - position - reconvene", turbulence, the fluid in addition to the above three conditions, will be a dramatic of eddy current in the direction of cross section, strong shear force for fluid, the fluid mix further segmentation, eventually required for mixed to form emulsion. Applied to the mix - transfer related process, including air/gas mixture, liquid/liquid extraction, gas/liquid reaction, strengthening heat transfer and liquid/liquid reaction process. Static mixer is widely used in plastics, chemical, pharmaceutical, mining and metallurgy, food, daily chemical, pesticide, cable, petroleum, paper making, chemical, biological, environmental protection and other industries. Due to the low consumption, saving investment, good effect, quick effect, has brought considerable economic benefits for the user.
