The chemical properties of titanium dioxide are relatively stable and generally do not react with other substances. It is mainly divided into brookite titanium dioxide, anatase titanium dioxide and rutile titanium dioxide. Titanium dioxide has a large market demand and is used in various fields. Including: coating, paper, plastic, prevention, ink, medicine and other industries. We'll share some details below.
The use of titanium dioxide:
First, the use of titanium dioxide in the coating industry
The paint industry is the largest user of titanium dioxide, especially rutile titanium dioxide, which is mostly consumed by the paint industry. The paint made of titanium dioxide has bright color, high covering power, strong tinting strength, less dosage and more varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. In addition, it prevents the penetration of UV rays and moisture, extending the life of the paint film.
2. The use of titanium dioxide in the plastics industry
The plastics industry is the second largest user. Adding titanium dioxide to plastic 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 use of titanium dioxide in the paper industry
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used for high-grade paper and tissue paper. Adding titanium dioxide to the paper can make the paper with good whiteness, good gloss, high strength, thin and smooth, impermeable during printing and light weight. Titanium dioxide for papermaking generally uses anatase titanium dioxide without surface treatment, which can be used as a fluorescent whitening agent to increase the whiteness of paper. However, composite paper needs to use surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
4. The use of titanium dioxide in the ink industry
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. Titanium dioxide used in the ink industry has rutile and anatase types.
5. The use of titanium dioxide in the textile industry
Textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold-red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not need surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the photocatalytic action of titanium dioxide, some special varieties need surface treatment.
6. The use of titanium dioxide in porcelain and other industries
The glaze made of titanium dioxide has strong transparency, low quality, strong impact resistance, good mechanical properties, bright color and is not easy to be polluted. Titanium dioxide for food and medicine is titanium dioxide with high purity, low heavy metal content and strong covering power.
