Explanation:
Pseudo-plastic substances are non-Newtonian fluids that exhibit a decrease in dynamic viscosity as the rate of shear increases. This means that the resistance to flow decreases as the shearing force increases. This behavior is commonly observed in thixotropic fluids such as paint, ink, and ketchup.
The behavior of pseudo-plastic substances can be explained by the fact that the flow of these fluids is governed by the orientation and alignment of their constituent particles or molecules. When a shearing force is applied, the particles or molecules start to align themselves in the direction of the force, which reduces their resistance to flow.
In summary, the characteristics of pseudo-plastic substances can be summarized as follows:
- Non-Newtonian fluids
- Exhibit a decrease in dynamic viscosity as the rate of shear increases
- Commonly observed in thixotropic fluids such as paint, ink, and ketchup
- Governed by the orientation and alignment of their constituent particles or molecules
