The Main Factors Affecting The Viscosity Of Micro Silica Powder (Silica Fume)?

The main factors affecting the viscosity of Ewende micro silica powder (silica fume) include:

1. pH value: the pH value of the silica fume slurry is directly related to the amount of alkali metal oxides (R₂O) contained in the silica fume, the larger the R₂O content, the higher the pH value of the silica fume. And the higher pH value leads to the higher potential, which in turn makes the viscosity of the silica fume slurry increase. In other words, the pH of the silica fume is the main factor affecting the viscosity of the slurry, and the larger the pH value, the higher the viscosity.

2. Matrix slurry viscosity: the size of the matrix slurry viscosity corresponds to the size of the viscosity of the added silica fume slurry, the smaller the matrix slurry viscosity, the greater the fluidity (degree) or flow value.

In practice, understanding these influencing factors helps to better control the effect of the use of micro silica powder. For example, in cases where a lower viscosity is required, this can be achieved by adjusting the relevant factors. Meanwhile, when storing micro silica powders, it is also necessary to pay attention to keeping them dry, using sealed containers, avoiding moisture and extrusion, etc., in order to maintain their good performance.
