The Powerlawequation, the Bills equation and Meter equation are introduced, and basic features are discussed. A new constitutive equation of pseudoplastic fluids are presented.
The result shows that the rheology property of paints present a shear-thinning effect, and the shearing stress and shear rate can be expressed in a modified power-lawequation.
实验结果表明，涂料呈剪切稀化特性，其剪切应力与剪切速率可用修改的幂律方程表示。
