Emulsifying equipment for waterborne polyurethane
The mechanical properties of the high shear dispersion emulsifier are suitable for the preparation process of waterborne polyurethane and the processing requirements of material properties.
Emulsification process of waterborne polyurethane
Since the method of polyurethane emulsion machine is due to the high tangent velocity produced by rotor high-speed rotation and high frequency mechanical effect, the strong momentum of the material in the narrow gap, rotor by strong mechanical and hydraulic shear layer, centrifugal extrusion, liquid friction, tear and turbulent combination of impact, emulsion (liquid/liquid) and foam (gas/liquid).
The emulsifier makes the solid phase, liquid phase and gas phase, which are insoluble in phase, disperse and emulsify uniformly and fine in an instant under the joint action of the corresponding ripening process and the right amount of additives. After the circulation of the high-shear dispersive emulsifier, the stable and high-quality products are finally obtained.
