Titanium dioxide powder is an inorganic chemical with extremely high hiding power and excellent whiteness. As a white pigment, it is widely used in many industrial fields, especially in the paper industry. In the process of papermaking, titanium dioxide powder is mainly used as filler and coating, and its functions and advantages are reflected in the following aspects.

Titanium Dioxide Powder Improves the Whiteness and Brightness of Paper

Titanium dioxide powder is widely used in paper industry to improve the whiteness and brightness of paper. The whiteness of paper is one of the important criteria to judge the quality of paper. The addition of tio2 powder can significantly improve the visual effect of paper, achieve higher whiteness and brightness, and meet the needs of high-quality paper. Whether in printing paper, writing paper, wrapping paper or special purpose paper, the white tone of tio2 titanium dioxide can make the paper more beautiful and clean.

Titanium Dioxide Powder Improves the Printing Performance of Paper  

Printing quality is closely related to the smoothness, whiteness and uniformity of paper surface. The high light scattering characteristics of titanium dioxide powder can effectively improve the printing effect of paper and make the printed patterns more vivid and clear. Because it forms a uniform coating on the surface of paper, titanium dioxide powder is helpful to improve the printing adaptability of paper, avoid ink penetration and ensure the clarity of patterns and characters.

Mechanical Properties of Paper Strengthened by Titanium Dioxide Powder  

When tio2 powder is added to paper as filler, it can enhance the mechanical strength of paper, such as tensile strength, tear strength and bursting strength. It can improve the physical properties of paper and enhance the durability and tear resistance of paper. In some demanding paper products, such as wrapping paper and cardboard, the addition of tio2 powder can significantly improve its quality and prolong its service life.

Titanium Dioxide Powder Improves Water Resistance and Oil Resistance of Paper  

The addition of ti02 powder can effectively improve the water resistance and oil resistance of paper, especially in the environment where water or oil is needed, such as food packaging paper, restaurant paper towels and so on. Titanium dioxide powder can be combined with other chemical additives to improve the water resistance of paper and prevent paper from being deformed or fragile in wet environment.

Titanium Dioxide Powder Provides Anti-Ultraviolet Protection and Reduces Production Cost  

Titanium dioxide powder has excellent anti-ultraviolet characteristics, which can effectively prevent the penetration of ultraviolet rays and avoid the damage of ultraviolet rays to paper. In paper products exposed to the sun for a long time, ti02 powder can effectively prevent paper from fading and aging, and prolong the service life of paper.

In the process of paper production, tio2 titanium dioxide can also be used as filler to replace some expensive wood pulp or other fiber raw materials, thus reducing production costs. Titanium dioxide powder has good dispersibility and fluidity, which can effectively improve the processability of pulp and enhance the efficiency in the production process.
