Description

technical field [0001] The invention relates to the field of on-line detection, in particular to a device and method for on-line detection of the blending effect of an eccentric rotor extruder. Background technique [0002] Polymer blending is a method of mixing two or more polymers in an appropriate proportion to obtain properties that cannot be achieved by a single polymer. The blending method of polymer is generally mixed by traditional single (twin) screw extruder. Compared with the traditional extruder screw, the eccentric rotor extruder based on the plasticizing transportation method of volume stretching deformation can effectively avoid the disadvantages of the traditional single (twin) screw shear flow field through its special spatial topological relationship, so that Polymer mixing is more thorough. Therefore, the online detection of the blending state of each section of the eccentric rotor extruder plays an important role in studying its blending mechanism and i...
