Read： 474 Time：13months ago Source：Transform the World with Simplicity

Titanium dioxide is an important inorganic chemical pigment, widely used in many fields, especially in the field of chemical production raw materials. It has many unique properties and uses, which will be described in detail below.

1. the properties of titanium dioxide

1. physical properties
titanium dioxide is a white powder, with good hiding power and tinting strength, insoluble in water, organic solvents and acids, but can be dissolved in alkali. Its particle size distribution and shape have an important influence on its properties.

2. chemical properties
titanium dioxide has strong chemical stability, can resist the erosion of oxygen, water, acid, alkali and other chemical substances in the atmosphere, so it has high weather resistance and chemical resistance.

2. the use of titanium dioxide

1.
in the field of coatings Titanium dioxide is one of the main pigments in coatings, can provide good hiding power and whiteness, improve the weather resistance of coatings, light resistance and chemical resistance. Widely used in construction, automobile, furniture and other industries.

2.
in the field of plastics, titanium dioxide can be used as an additive in plastics to improve the weather resistance, heat resistance and mechanical properties of plastics. In the outdoor use of plastic products, adding titanium dioxide can effectively extend its service life.

3.
in the field of papermaking Titanium dioxide can be used in the paper industry to improve the whiteness and opacity of the paper and improve the appearance quality of the paper. At the same time, it can also improve the weather resistance and chemical resistance of the paper.

4.
in the field of printing ink titanium dioxide can be used as the pigment of printing ink, providing good color effect and hiding power, and improving the quality and grade of printed matter.

In short, titanium dioxide, as an important raw material for the production of chemical products, has a wide range of uses and good properties, and plays an important role in improving product quality and prolonging service life.
