Surface properties of titanium dioxide
As a titanium dioxide manufacturer, adjusting the surface properties of titanium dioxide according to different product positioning and customer needs is a very effective and extremely simple way. This adjustment can be achieved through inorganic coating, organic treatment, or a combination of the two.
Organic treatment is currently used by more and more manufacturers in the titanium dioxide manufacturing industry. The main principle is that a small amount of organic treatment agent can be anchored on the surface of the titanium dioxide through the action of a hydroxyl bridge, and then stretch out into the system. Various hydrophilic groups or lipophilic groups or both, thereby improving the dispersibility of the product in different systems.
In the production process of titanium dioxide, organic treatment agents can often also play a role in assisting grinding, and can improve other properties such as whiteness, decolorization rate, and particle characteristics of the product. Therefore, many domestic manufacturers are increasingly inclined to Use organic treatment agent as an important means to adjust the surface properties of titanium dioxide.
However, the introduction of organic treatment agents when dispersing in the water phase system usually brings about a problem of more foam, which will cause unnecessary trouble to the user, and even directly cause some performance degradation of the coating. Therefore, we can also consider improving the surface properties of titanium dioxide through inorganic treatment to overcome the above shortcomings. As mentioned earlier, different inorganic treatment processes can change the surface properties of titanium dioxide. Therefore, we tried a variety of inorganic treatment process conditions for the exterior wall latex paint system, and finally determined the current NR950 production process, and achieved certain Effectiveness. Because this model product overcomes the shortcomings of foaming, it has won praise from users.
On the basis of inorganic treatment, the organic treatment is controlled at an appropriate level, and the application performance of our products will have a better effect.
