Cone and Plate Viscometer
Paints or inks often are in different shear rates status from manufacturing to application. As a typical non-Newtonian fluid, paints or inks always show different viscosity characteristics at different shear rates.
Generally speaking, paints are in a low shear rate state when it is stored, transported, levelling, and sagging. But they are in the medium shear rate when being pumped, dipped, and mixed at a low speed. At high-speed dispersion, roll, spray, and brush coating, they are in a high shear state, and the shear rate is generally 9000s⁻¹ to 12000s⁻¹. Therefore, understanding the rheological characteristics of paints or inks at such high shear rates requires the use of a cone-plate viscometer to measure.
The BGD 182 Cone-and-plate Viscometer uses a special angle conical spindle, which generates a very high shear rate on the measured sample under the high-speed drive of a stepper motor. It conforms to ISO 2884-1 (Paints and varnishes — Determination of viscosity using rotary viscometers — Part 1: Cone-and-plate viscometer operated at a high rate of shear).
