The scientific name of titanium dioxide titanium dioxide (Titamium Dioxide). It has rutile (Rutile R-type) and anatase (Auatase A-type) two kinds of structures, rutile crystal structure of dense, relatively stable, and optical activity is small, so weather is good, while a higher opacity, color power consumption , and thus have a better application performance, access to a wider range of applications. Chemical properties of titanium dioxide is extremely stable, gender is an acidic oxide. Room temperature almost no reaction with other elements and compounds, oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulfur dioxide does not work, do not dissolve in water, fat, do not dissolve in acid and inorganic acid, alkali, hydrogen is only soluble in hydrofluoric acid. However, in the light under the effect of titanium dioxide can occur consecutive redox reactions, has photochemical activity. This kind of photochemical activity, UV light especially anatase titanium dioxide, titanium dioxide, even if some of the nature of the photosensitive inorganic compounds oxidation catalysts, but also some of the organic photosensitive reduction catalyst. Titanium dioxide is widely used in various types of structure, surface coating, paper coating and filler, plastics and elastomers, other uses include ceramics, glass, catalysts, coated fabrics, printing inks, roofing granules and flux.
Titanium dioxide in the rubber industry, both as a coloring agent, but also has reinforced, anti-aging, filling the role. In the white and colored rubber products by adding titanium dioxide, in the sunlight, sun-resistant, non-cracking, discoloration, stretch rate is high and the acid. Rubber with titanium dioxide, used automobile tires and rubber shoes, rubber flooring, gloves, sports equipment, etc., generally anatase-based. But for car tire production, often by adding a certain amount of rutile products to enhance anti-ozone and UV resistance.
Titanium dioxide in cosmetics applications are becoming increasingly widespread. Because non-toxic titanium dioxide, white lead is superior than the various titanium dioxide powder to replace almost all of white lead and zinc white. Powder in only 5% -8% of white titanium dioxide can be permanent, so that a more creamy flavor, with adhesion, absorption and opacity. In gouache and cream in a transparent titanium dioxide can be reduced and the feeling greasy. Variety of other spices, sunscreen, soap flakes, white soap and toothpaste are also available titanium dioxide.
Obtained with titanium enamel transparency, and has a mass of small, impact resistance, good mechanical properties, colorful, easy to pollution and so on. Food and medicine for the use of high purity titanium dioxide, heavy metals content is low, hiding power of titanium dioxide.
