Description:
*The application of nano-iron oxide in decorative materials
Among pigments, nano-iron oxide is also called transparent iron oxide (permeable iron). The transparent iron oxide pigment has a particle size of 0.01μm, so it has high chroma, high tinting power and high transparency. After special surface treatment, it has good grinding and dispersibility. Transparent iron oxide pigments can be used for oily and alkyd, amino alkyd, acrylic and other paints to make transparent paints, which have good decorative properties.
*The application of nano-iron oxide in ink materials
Iron oxide yellow can be used for coating the outer wall of cans. Nano iron oxide red ink is red-gold, especially suitable for the inner wall of cans. In addition, iron oxide red is resistant to high temperatures of 300 ℃. It is a rare pigment in ink. In order to improve the printing quality of banknotes, nano-iron oxide pigments are often added to banknote printing inks to ensure the chroma and chroma of banknotes.
*The application of nano iron oxide in colorant
With the improvement of people's living standards, people pay more and more attention to colorants used in medicine, cosmetics, and food. Non-toxic colorants have become the focus of attention. Nano-iron oxide is a good coloring agent under strict control of arsenic and heavy metal content.
*The application of nano-iron oxide in light-absorbing materials
The Fe2O3 nano-particle polysterol resin film has good absorption capacity for light below 600 nm, and can be used as an ultraviolet filter for semiconductor devices.
*Application of nano-iron oxide in magnetic materials and magnetic recording materials
Nano Fe2O3 has good magnetic properties and good hardness. Oxygen magnetic materials mainly include soft magnetic iron oxide (α-Fe2O3) and magnetic recording iron oxide (γ-Fe2O3). Magnetic nanoparticles have the characteristics of a single magnetic domain structure and high coercivity due to their small size. Using them to make magnetic recording materials can increase the signal-to-noise ratio and improve image quality.
*The application of nano iron oxide in catalyst
Nano-iron oxide has a huge specific surface area and significant surface effect. It is a good catalyst. Due to the small size of the nanoparticle, the surface volume percentage is large, the bonding state and electronic state of the surface are different from the inside of the particle, and the incomplete coordination of surface atoms causes the surface active sites to increase. The activity and selectivity of the catalyst made of nanoparticles are higher than ordinary catalysts, and it has a long life and is easy to operate.
