Are you familiar with mixers? Do you know how they mix? To help users gain a detailed understanding of the product knowledge, the editor will briefly introduce the relevant knowledge points below.

In reality, there are three flow states within a blender: laminar, transitional, and turbulent. The primary parameter that determines these states is viscosity. Viscosity refers to a fluid's resistance to flow, defined as the magnitude of shear stress required on a 1 cm² surface area for a liquid to flow at a rate of 1 cm/s, known as kinematic viscosity, measured in Pa. During the blending process, it is generally considered that fluids with a viscosity less than 5 Pa/s are low-viscosity, such as water, oil, sauce, lubricating oil, and low-viscosity emulsions; those between 5-50 Pa/s are medium-viscosity, like ink and toothpaste; those between 50-500 Pa/s are high-viscosity, such as chewing gum, plasticizer solutions, and solid fuels; and those above 500 Pa/s are ultra-high-viscosity, such as rubber blends, plastic melts, and organosilicones. For low-viscosity media, a blender with a small diameter and high speed can drive the circulation of the surrounding fluid to distant areas. However, for high-viscosity media, the blender must be used to directly propel the fluid. Therefore, when selecting the blending method for a blender, one should make a judgment based on various factors, and only by choosing a more suitable blending method can the efficiency of use be maximized, thereby driving the operation of the entire equipment.
