Application and properties of iron oxide red pigment

Characteristics of iron oxide red: Iron red has good heat resistance, does not change color at 500℃, at 1200℃, does not change the chemical structure, extremely stable; It can absorb the ultraviolet spectrum in the sunlight, so it has a protective effect on the coating, resistant to dilute acid, alkali, water, solvent, so that it has good weather resistance.

When the particle size of iron red is 0.2um, the yellow phase, the specific surface area and oil absorption are also relatively large. When the particle size increases, the hue moves from red to purple, and the specific surface area and oil absorption are also smaller.

The production process of iron oxide red pigment: the production process of iron oxide red is mainly divided into two kinds: natural mineral method and hydrolysis method. Natural mineral method is the use of natural iron ore through high temperature coagulation to obtain iron oxide red;The hydrolysis rule is based on iron salt as raw material, and iron oxide red is obtained by controlling the hydrolysis conditions.

Application fields of iron oxide red pigments: The application fields of iron oxide red pigments are very wide. In the coating industry, it is used in the manufacture of alkyd resin paint, nitro paint, acrylic acid paint, etc. In the plastic industry, it is used in the production of red plastics; Used in the rubber industry to make red rubber products; Used in the ceramic industry to make red ceramics; Used in the leather industry to make red leather products. In addition, iron oxide red is also used in paint, ink, printing and dyeing and many other fields.

Market status of iron oxide red material: With the continuous development of domestic and foreign manufacturing industry, the market demand for iron oxide red is growing. Globally, the production and consumption of iron oxide red are mainly concentrated in Asia, Europe and North America. As the largest producer of iron oxide red, China accounts for more than half of the world’s production and consumption. It is expected that in the next few years, with the recovery of the global economy and the rise of emerging markets, the market demand for iron oxide red will continue to grow.

Future development trend of iron oxide red pigment: With the increasing awareness of environmental protection and the promotion of green manufacturing, the production process of iron oxide red in the future will pay more attention to environmental protection and energy saving. The use of iron oxide red is relatively environmentally friendly, will not pollute the environment, and is in line with environmental protection requirements. Therefore, in the construction and coating industries, the choice of using environmentally friendly iron oxide red with production can increase the image of the enterprise, beware of product quality, and the market prospect is more open. In addition, with the continuous emergence of new materials and the expansion of application fields, the application prospect of iron oxide red will be more broad.
