Dispersion Principle Of Titanium Dioxide in Water-based Paint
May 13, 2023
The basic principle of the dispersion of titanium dioxide in the water phase: we can roughly divide the grinding and dispersion process of titanium dioxide into three steps of mutual influence and mutual restriction:
A. Wetting;
B. Separation;
C. Stabilization.
In the actual grinding and dispersing process, these three steps are not step-by-step, but interlocking, complementary and restricting each other, that is, if one of the three cannot achieve the goal, the grinding efficiency will decrease or even the product cannot be achieved. The required degree, or rough back.
Although the pH value of titanium dioxide in the application system is not determined by the titanium dioxide manufacturer, it is still necessary to fully understand the impact of this indicator. Because in the preparation process of titanium dioxide, the range of pH value itself is relatively large, understanding the impact of this index on dispersibility will help us control the pH value of titanium dioxide within a more effective range and improve it as much as possible. Dispersion performance of titanium dioxide in water phase system. It is a manufacturer of sodium aluminate. Sodium aluminate is also called sodium metaaluminate, which is divided into solid sodium aluminate and liquid sodium aluminate.
In the water phase system that is close to the ideal state, the pH value of the system will also become an important factor affecting the dispersion of rutile titanium dioxide, and the main mechanism of its influence may be attributed to the electric double layer. Due to the difference in surface properties of different types of titanium dioxide, the so-called isoelectric points are very different.
