Plastic resin in liquid or emulsion state or dispersion system Measuring Apparent Viscosity with Single-Cylinder Rotary Viscometer

1 Scope

This document specifies the method for measuring the apparent viscosity of liquid resin with a single-cylinder rotary viscometer. The viscosity measurement range of this method. 0.02Pa·s~60000Pa·s. This document applies to Newtonian fluids and non-Newtonian fluids, and the apparent viscosity of the measured liquid depends on the velocity gradient during the measurement.

2 Normative references

There are no normative references in this document.

3 Terms and definitions

The following terms and definitions apply to this document. ISO and IEC maintain terminology databases at the following websites. 3.1 Singlecylindertyperotationalviscometer Determine the viscosity by measuring the torque acting on the surface of a single rotating cylinder or disc at a constant angular velocity in a laminar flow state Device. 3.2 Rotor spindle Rotatable coaxial objects such as cylinders or discs connected to a vertical rotation axis. 3.3 Apparentviscosity Use a predetermined calibration table to determine the viscosity of the liquid/fluid based on the measured torque. Note. For non-Newtonian fluids, the apparent viscosity depends on the shear rate. With these types of viscometers, the speed gradient at each point of the rotor is different. because Therefore, for non-Newtonian fluids, the result is not strictly "known true viscosity", so it is usually called apparent viscosity.

4 Principle

4.1 General The coaxial rotor rotates at a constant speed in the measuring liquid. The resistance exerted by the liquid on the spindle depends on the viscosity of the liquid, and the resulting torque is measured by an appropriate device. The method of measuring the apparent viscosity using a single-cylinder rotary viscometer is to multiply the torque reading by a coefficient related to the rotor speed and characteristics. ......
