Uses of Titanium Dioxide

May 13,/2022

1.) The paint industry is the first major user of titanium dioxide, especially rutile titanium dioxide, most of which is consumed by the paint industry. With the development of China’s automobile industry and construction industry, the coating industry not only needs more titanium dioxide in quantity, but also has higher requirements for variety and quality. Paint made of titanium dioxide, bright color, high hiding force, strong coloring force, saving amount, variety, the physical stability of the medium can play a protective role, and can enhance the mechanical strength and adhesion of the paint film, prevent cracks, prevent ultraviolet rays and moisture leakage, prolong the life of the paint film. We are high quality titanium dioxide manufacturer.


2.) The plastics industry is the second largest user of titanium dioxide. The addition of titanium dioxide in plastics can improve the heat resistance, light resistance and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of products, and prolong service life.


3.) The paper industry is the third largest user of titanium dioxide. Titanium dioxide is used as a paper filler, mainly used in high-grade paper and thin paper. The addition of titanium dioxide in the paper can make the paper have a good whiteness, good gloss, high strength, thin and smooth, non-penetrating when printing, and light weight. Titanium dioxide for papermaking generally uses anatase titanium dioxide without surface treatment, which can play the role of fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of rutile titanium dioxide after surface treatment to meet the requirements of light and heat resistance.


4.) Titanium dioxide is an indispensable white pigment in high-grade inks. Inks containing titanium dioxide are durable and discolored, have good surface wetting and are easy to disperse. Titanium dioxides used in the ink industry are rutile type and anatase type.


5.) Textile and chemical fiber industry is another important application area of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Because the anatase type is softer than the rutile type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but some special varieties need surface treatment in order to reduce the photochemical effect of titanium dioxide and avoid the reduced role of fibers in titanium dioxide photocatalytic effect.


6.) Titanium dioxide in the rubber industry not only as a colorant, but also has a reinforcing, anti-aging, filling effect. In the white and colored rubber products add titanium dioxide, in the sunlight irradiation, resistant to sun, do not crack, do not change color, and the elongation rate is large and acid and alkali resistance. Titanium dioxide for rubber, mainly used in automobile tires and rubber shoes, rubber flooring, gloves, sports equipment, etc., generally anatase type. However, when used in the production of automobile tires, a certain amount of rutile products is often added to enhance their anti-ozone and ultraviolet resistance.


7.) Titanium dioxide is also increasingly widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, all kinds of incense powders almost use titanium dioxide to replace lead white and zinc white. Only 5-8% titanium dioxide needs to be added to the incense powder to get a permanent white, making the spice creamier, with adhesion, absorption and covering power. Titanium dioxide in gouache and cold creams reduces the feeling of greasiness and transparency. Titanium dioxide is also often used in various other spices, sunscreens, soap tablets, white soaps, shaving creams and toothpastes.


8.) Titanium dioxide is also widely used in the production of enamel in ceramics. The porcelain glaze obtained has strong transparency, light weight, strong impact resistance, good mechanical properties, bright colors, and is not easy to pollute. Generally, it is mostly high temperature resistant anatase titanium dioxide.
