Application fields, characteristics and uses of titanium dioxide

Titanium dioxide is an excellent white pigment, which is safe and non-toxic. It has excellent hiding power, coloring power, weather resistance, water resistance, good yellowing resistance, excellent whiteness, brightness and gloss, stable chemical performance, and does not react with any substance at normal temperature. Its main component is TiO2.

The main application areas of titanium dioxide include coatings, plastics, inks, and papermaking, with coatings accounting for 60%, plastics accounting for 20%, papermaking accounting for 14%, and other fields (including cosmetics, chemical fibers, electronics, ceramics, enamel, welding electrodes, alloys, glass, etc.) accounting for 6%.

1、 Coatings are very important users of titanium dioxide, especially the largest users of rutile titanium dioxide, most of which are consumed by the coating industry. The paint made of titanium dioxide has bright color, strong covering power, strong coloring power, low dosage and many varieties, which can protect the stability of the medium, enhance the mechanical strength and adhesion of the paint film, prevent cracking, prevent UV and UV water penetration, and extend the life of the paint film

2、 The plastic industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, thereby improving their physical and chemical properties, enhancing their mechanical strength, and extending their service life. service life.

3、 Paper industry is the third largest user of titanium dioxide, which is used as paper filler, mainly for high-grade paper and tissue paper. Adding titanium dioxide to paper can make it have better whiteness, good glossiness, high strength, thin and smooth, non permeable printing, and good gloss. Titanium dioxide for paper making generally uses anatase titanium dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of the paper. However, rutile titanium dioxide needs to be used after surface treatment of laminated paper to meet the requirements of light resistance and heat resistance.

4、 Titanium dioxide in rubber industry is not only used as colorant, but also has the functions of reinforcement, anti-aging and filling. Titanium dioxide is added to white and colored rubber products, which can withstand sunlight, no cracking, no discoloration, tensile ratio and acid and alkali resistance under sunlight. Titanium dioxide for rubber is mainly used for automobile tires and rubber shoes, rubber floors, gloves, sports equipment, etc., and it is mainly anatase titanium dioxide. But for the production of automobile tires, a certain amount of rutile products are often added to enhance the ability to resist ozone and ultraviolet rays.

5、 Cosmetic grade titanium dioxide is divided into oily and water-based titanium dioxide. Due to its stable chemical properties, high refractive index, high opacity, high hiding power, good whiteness, and no toxicity, it is widely used in the field of cosmetics, with the effect of beauty and whitening.

6、 Titanium dioxide is also an essential white pigment in advanced inks. Ink containing titanium pigments is durable, does not change color, has good surface wettability, and is easy to disperse. The titanium dioxide used in the ink industry is rutile type, and there are also anatase titanium dioxide.

7、 Textile and chemical fiber industry is another important application field of titanium dioxide. Chemical fiber grade titanium dioxide is mainly used as a matting agent. Because anatase titanium dioxide is softer than rutile titanium dioxide, anatase is usually used. Generally, titanium dioxide used in chemical fibers does not need surface treatment, but some special varieties need surface treatment to reduce the photochemical effect of titanium dioxide and avoid the degradation of fiber's photocatalytic effect in titanium dioxide.

8、 Enamel industry is an important application field. Enamel grade titanium dioxide has the characteristics of high purity, good whiteness, bright color, uniform particle size, high refractive index, strong decolorization, strong opacities and opacity.

9、 The enamel industry is an important application field. Titanium dioxide enamel grade titanium dioxide has the characteristics of high purity, good whiteness, bright color, uniform particle size, high refractive index, strong decolorization force, strong opacification and opacity. After coating, technical personnel need to apply thin, smooth, and acid resistant products made in the enamel process, which can be evenly mixed with other materials, do not agglomerate, and are not easy to melt.

10、 Ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, high opacity, thin coating, light weight, and is widely used in ceramics, architecture, decoration and other materials.

These are the application fields and uses of titanium dioxide. Its performance characteristics are high whiteness, strong hiding power, hydrophilic and oleophilic products. It overcomes the defects of general titanium dioxide in their respective dispersion systems, such as being difficult to disperse and easy to precipitate, and significantly improves its dispersibility, precipitation resistance, and weather resistance.
