The importance of dispersants for titanium dioxide

Titanium dioxide, also known as titanium dioxide, titanium sugar, titanium dioxide, is a white solid or powdery amphoteric oxide with a molecular weight of 79.9. It is a white inorganic pigment that is non-toxic, has the best opacity, whiteness, and brightness, and is considered one of the best performing white pigments in the world today. Has excellent whiteness and brightness, and strong coverage. It is one of the ideal white pigments in the world. It is widely used in coatings, plastics, rubber, paper, chemical fiber inks, and cosmetics. And other industrial sectors. Today, we will mainly analyze the importance of titanium dioxide dispersants.

Due to its excellent photochemical activity, titanium dioxide oxidizes the organic compounds in contact with it when exposed to visible or ultraviolet light, causing degradation, embrittlement, and pulverization of the organic compounds in contact. Therefore, in industrial production, surface treatment of titanium dioxide is usually carried out by coating inorganic oxides to compensate for this defect of titanium dioxide. Before surface treatment, titanium dioxide is first dispersed and slurried, and the dispersibility of the resulting slurry directly affects the surface treatment effect of titanium dioxide. If the titanium dioxide particles are unevenly dispersed, not only can continuous and uniform coating be achieved, but also the scattering of pigment particles towards light can be achieved, thereby reducing the optical and pigment properties of the pigment, and even possibly reducing the optical and pigment properties of the pigment. The subsequent jet grinding process. The coating is damaged, which affects the weather resistance of the pigment. Therefore, it is particularly important to choose titanium dioxide as a dispersant before surface treatment.
