As an emulsified asphalt material often used in the road and waterproof industry, its viscosity factors include the asphalt concentration of emulsified asphalt, the size and distribution of asphalt particles; thickener and interface film; shear rate and temperature.

What are the aspects of emulsified asphalt equipment that affect the viscosity of emulsified asphalt?

The particle size and distribution of asphalt are affected by the preparation process and formulation of emulsified asphalt. The study found that the correlation ratio between the particle diameter of emulsified asphalt and the viscosity has put forward a mathematical model. When other influencing factors remain unchanged, the particle size distribution has a The influence trend of viscosity is that with the increase of the median particle size of emulsified asphalt and the widening of the particle size distribution of emulsified asphalt, the Engla viscosity of emulsified asphalt gradually decreases. On the contrary, the particle diameter of emulsified asphalt is unimodal, and the viscosity of emulsified asphalt with smaller particle size is larger. The focus of the value is that the viscosity of emulsified asphalt with bimodal particle diameter distribution is several times lower than that of unimodal emulsified asphalt with the same solubility.
In emulsified asphalt equipment, colloid mill is one of the key factors to determine the diameter of asphalt particles in emulsified asphalt. The mechanical fit clearance and effective shear area of the colloid mill are related to the particle size of the emulsified asphalt. Therefore, when choosing emulsified asphalt equipment, you cannot simply choose the equipment that can make emulsified asphalt. With the improvement of road construction standards and the strict quality life-long system, the selection of high-end emulsified asphalt equipment is a necessary condition.
