Factors for downstream industries to choose titanium dioxide applications（B）Author：admin Time：2021-06-10
3. Coloring power
Coloring power is an important characteristic index of titanium dioxide, that is, after titanium dioxide is mixed with another pigment, the ability of the mixture to display its own pigment can be obtained. That is to say, for white pigments, after it is mixed with a dark pigment, the lighter the color of the mixture, the stronger its tinting power (decreasing power).
4. Oil absorption
Oil absorption is also one of the important pigment properties of titanium dioxide, because it relates to the filling state of titanium dioxide in the vehicle and can explain its dispersibility in the medium. In the paint industry, it is used to estimate the consistency of the paint before mixing, guide the formulation of the paint, and can preliminarily calculate the pigment volume concentration (pvc).
5. Chemical composition
The chemical composition of titanium dioxide determines the chemical properties of titanium dioxide. It is the main symbol of the difference between pigments. In addition to reflecting a series of pigment properties of the pigment, such as whiteness, color reduction power, oil absorption, etc., its application Performance effects are also great, such as weather resistance, dispersibility, etc.
