Introduction And Application Of Titanium Dioxide

- Nov 19, 2019-

Titanium dioxide, the scientific name of titanium dioxide (TiO2), is a very stable oxide with excellent optical and pigment properties and is mainly used as a white inorganic pigment. Its non-toxic, best opacity, best whiteness and brightness are considered

It is currently the world's best performing white pigment, widely used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries.

Titanium dioxide has three crystal forms, which are rutile, anatase and titanium. Among them, the plate titanium type cannot be used as a pigment, and the industrial use as a pigment is mainly anatase type and rutile type titanium dioxide.

Titanium dioxide has the advantages of high purity, uniform particle size, good optical performance, strong refractive power, high decolorizing power, strong hiding power, low oil absorption and high water dispersibility. It is mainly used in coatings, inks, chemical fiber, rubber and glass. ,cosmetic,

Industries such as soap, plastics and paper. In addition to the advantages of anatase titanium dioxide, rutile titanium dioxide has better weatherability and hiding power, and is mainly used in advanced industrial pigments, glazed latex coatings, plastics, and has high achromatic power.

Rubber materials for high lightfastness, high-grade paper coatings and wax paper. From the viewpoint of pigment properties, rutile titanium dioxide is superior to anatase titanium dioxide, and rutile titanium dioxide is mostly surface-coated. In 2010, China's gold

Redstone titanium dioxide accounts for 57% of the total titanium dioxide, far below the world's 90% level. In the future, there is still much room for improvement in the proportion of rutile titanium dioxide in China.

Currently, the titanium dioxide industry is undergoing three major adjustments:

(1) The world titanium dioxide production growth is relatively slow, while the Asia-Pacific region, especially China's titanium dioxide production is growing rapidly, and the world titanium dioxide industry is shifting to the Asia-Pacific region, especially China;

(2) With the higher requirements for the performance of titanium dioxide in the downstream, the coating treatment of titanium dioxide has become an important means, various special-purpose titanium dioxides have emerged, and the development of titanium dioxide industry from general supplies to special products is in the ascendant;

(3) Titanium dioxide is divided into two types: anatase and rutile. Although anatase titanium dioxide still occupies part of the market share due to its high cost performance, rutile titanium dioxide is still the future development of the industry due to its excellent performance. Big trend

Potential. In China's titanium dioxide product structure, the proportion of rutile titanium dioxide is increasing, accounting for 57%, but still far below the world's 90%. China's titanium dioxide product structure is actively turning to rutile titanium dioxide

change. In summary, China's titanium dioxide industry, especially the special rutile titanium dioxide prospects are still optimistic.

Application of titanium and titanium alloy

Titanium is an important structural metal developed in the 1950s. Titanium alloy has low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic, non-magnetic, weldable, biocompatible, and surface. Can be decorated with strong features, wide

It is widely used in aviation, aerospace, chemical, petroleum, electric power, medical, construction, sporting goods and other fields. Many countries in the world have recognized the importance of titanium alloy materials, and have researched and developed them successively.

use.

In 2011, the proportion of global commercial aviation consumption reached 46%, the proportion of military titanium materials was 9% (mainly military aviation), and the proportion of titanium consumed in the entire aviation field exceeded 50%;

The proportion of industrially consumed titanium is 43%, and that of emerging markets is 2%.

There is a significant difference in the demand structure of titanium products in the region.

In North America and the European Union with developed aerospace and military defense industries, especially in the United States, about 50% of demand for titanium products comes from aerospace and military defense.

In Japan, industrial titanium from the chemical industry and other industries dominates demand. According to the Japan Titanium Association, aerospace accounts for only 2% to 3% of Japan's titanium demand. Similar to the situation in Japan, most of the demand for titanium products in China

From the chemical and energy sectors, aerospace accounts for only 10%. Although China has become one of the world's largest producers and consumers of titanium, most of its production has been limited to lower grade titanium for bicycle racks and golf balls.

Rod or anti-corrosion pipe used in the chemical industry. However, in recent years, the amount of titanium used in aerospace has increased significantly in the Asian region. It can be seen that the prospect of the titanium market is relatively bright.
