1, titanium dioxide is titanium dioxide (Titamium Dioxide) trade name.

2, the classification of titanium dioxide

　　According to the production process route is divided into sulfuric acid titanium dioxide, chloride titanium dioxide.

　　According to the crystallization form is divided into anatase and rutile two categories.

　　According to the use of the object is divided into pigment titanium dioxide and special special titanium dioxide and so on.

　　2.1, paint: bright colors, high hiding power, strong coloring power, dosage, more varieties, the physical stability of the medium can play a protective role, and can enhance the mechanical strength of the film and adhesion, prevent cracks, prevent ultraviolet rays and moisture through the film to extend the life of the film.

　　2.2, plastics: add titanium dioxide, can improve the heat resistance, light resistance, weather resistance of plastic products, so that the physical and chemical properties of plastic products to improve, enhance the mechanical strength of the products, prolong service life.

　　2.3, papermaking: so that the paper has a better whiteness, good luster, high strength, thin and smooth, printing does not penetrate, light quality.

　　2.4, ink: ink containing titanium dioxide is durable and does not change color, good surface wettability, easy to disperse.

　　2.5 Rubber: both as a coloring agent, but also has a reinforcing, anti-aging, filling effect.

　　2.6, cosmetics: because titanium dioxide is non-toxic, far superior to lead white, so a variety of fragrant powder almost all use titanium dioxide to replace lead white and zinc white.

　　2.7, textile and chemical fiber: chemical fiber titanium dioxide is mainly used as a matting agent. Because anatase is softer than rutile, so generally use anatase.
