Detailed Introduction to Titanium Dioxide Knowledge
Titanium dioxide is an important inorganic chemical raw material, widely used in coatings, plastics, paper, rubber and cosmetics industries. Internationally, titanium dioxide is often called the "white star". The following is a detailed introduction to titanium dioxide.
1. Types and properties of titanium dioxide
Based on the different preparation processes and physical properties, titanium dioxide can be divided into two categories: sulfuric acid based titanium dioxide and chloride based titanium dioxide. Sulfuric acid based titanium dioxide is made from ilmenite by the sulfuric acid method. Chloride based titanium dioxide is made from natural ilmenite by the chlorination method. Sulfuric acid based titanium dioxide is whiter in color and has a higher glossiness, while chloride based titanium dioxide is yellower and has a wider range of applications.
Titanium dioxide is a non-toxic, odorless, non-magnetic, chemically stable white granular powder. Its chemical formula is TiO2, and its relative molecular mass is 79.88. Titanium dioxide has excellent hiding power, high gloss, excellent weather resistance and chemical stability. In addition, titanium dioxide also has the characteristics of strong UV resistance, high temperature resistance, acid and alkali corrosion resistance, etc.
2. Application fields of titanium dioxide
1) Paint industry: Titanium dioxide is widely used in paints, mainly to improve the hiding power, adhesion and weather resistance of paints. In addition, titanium dioxide can also provide color brightness and clarity, giving the coating a beautiful appearance. Due to the high quality requirements of the paint industry, there are strict requirements for the purity, color and particle size of titanium dioxide.
2) Plastic industry: Titanium dioxide is the most important white pigment in plastic products. It can increase the whiteness and brightness of plastic products and improve their hiding power. In addition, titanium dioxide also plays an anti-UV and anti-oxidation role in plastics, thereby extending the service life of plastic products.
3) Paper industry: Titanium dioxide, as a filler and coating for paper, can improve the gloss, smoothness and weather resistance of paper. At the same time, titanium dioxide can also improve the hiding power and printing quality of paper, making the printed text and images clearer.
4) Rubber industry: Titanium dioxide can be used to whiten and improve the appearance of rubber products, such as rubber shoes, rubber tubes, etc. In addition, titanium dioxide can also increase the weather resistance and light resistance of rubber products, improve their physical properties and service life.
5) Cosmetics industry: Titanium dioxide is widely used in cosmetics, such as foundation, loose powder, lipstick, etc. Titanium dioxide can provide whiteness and concealing power of cosmetics, making the skin look smoother and more even.
3. Production process of titanium dioxide
Sulfuric acid method: The sulfuric acid method is the earliest industrial production method for titanium dioxide. This method uses natural ilmenite as raw material and is produced through leaching, dissolution, crystallization, separation, washing, drying and other processes. The sulfuric acid method based titanium dioxide has high purity and stable quality, but the production process is complicated.
