Titanium Dioxide(TIO2)
Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.
It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.
Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.

At present, developed countries in Europe and the United States are competing to develop OLED lighting. In the past two years of major architectural and lighting exhibitions, we can see a variety of OLED lighting displays. In essence, the starting point for the development of OLED lighting and LED lighting in all countries is the same.
First of all, OLED lighting is extremely energy efficient. Secondly, the light quality of OLED is comfortable, the light is visible light, there is no infrared light, ultraviolet light, and the blue light component is also rare, which is more effective for eye protection. Finally, the OLED is thinner and lighter, and the entire device contains more than a dozen layers of organic film, which add up to less than 1 thickness of the hair.
In principle, OLEDs and LEDs are quite similar. But in terms of energy efficiency, OLED is essentially different from other light sources. Traditional lamps are basically line sources made of point light sources. Although the light source is very bright, it is generally installed in the lamp cover in practical applications, which will lose a lot of energy efficiency. The OLED itself is a surface light source, and naturally no lampshade is needed. At present, the energy efficiency of OLED light sources is not as good as that of LEDs, but in terms of lamps, the potential of OLEDs is the largest. Therefore, we cannot define OLED as a light bulb or light source, but rather as a new type of luminaire.
For OLED lighting, China's development opportunities are the largest in the world. On the one hand, domestic OLED technology is not only behind, but is ahead of international competitors. On the other hand, there is a huge potential market in the country. At present, due to the market situation, most of the LED lighting products are still in the form of traditional lighting substitutes, take the traditional light bulbs down and replace the LED bulbs. But OLED can't, it must be a new fixture, so the best market is the new building. In the next 10 years, China's new construction area is about 20 billion square meters. As a new choice for new building luminaires, with the deepening of the concept of energy saving and emission reduction, it is believed that OLED lighting can survive in the enlightenment stage.
The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to 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 the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
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. The titanium dioxide used in the ink industry has rutile type and anatase type.
The 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 require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The 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, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
