Description
technical field [0001] The invention relates to a mixing type torque rheometer rotor, in particular to a novel mixing type torque rheometer rotor. Background technique [0002] The existing mixing-type torque rheometer rotor has poor adaptability to PVC materials, and the test results are unreliable when used to study and analyze the plasticizing behavior of PVC blends during processing. Contents of the invention [0003] The purpose of the present invention is to provide a novel mixing type torque rheometer rotor, which is mainly used in the research of PVC materials. [0004] The new mixing type torque rheometer rotor includes a rotor body. The rotor body has a front long edge, a front middle edge, a front short edge, a rear long edge, a rear middle edge, and a rear short edge. The shape is concave inward, the rear end surface of the rotor body is convex outward, the front long edge of the rotor body intersects with the rear short edge, the front middle edge of the roto...
