Cerium Oxide – What’s it all about?
Cerium oxide is either a pale yellow or light brown powder. The bulk density of Cerium oxide is approximately 7.13g/cm3, and the melting point at 2397. The substance is insoluble with water and alkali but somewhat soluble with acid. To make cerium trioxide, heat can reduce cerium oxide to 2000°C at 15MPa. Cerium oxide turns slightly yellowish or reddish if it is exposed to temperatures between 2000°C & 5MPa. It can be used as a polishing material, catalyst carrier (auxiliary agent), catalyst, catalyst, or catalyst, and also for fuel cell electrolytes.
Antifogging Glass Agent
Wet or rainy weather can make it easy for moisture to form on glass products like building glass, windshields, rearview lenses, spectacle lenses, and more. This is due to humidity. Water droplets that form on glass substrate in the shape or a small circle can cause a prism-like reflection effect. It also affects visibility and light transmittance. Fogging of glass may cause problems in people’s lives and can even pose a danger to their safety. The visibility of light transmittance and mirror imaging will be affected by particles like dust or oil. This is why anti-fogging can be closely linked to both work and personal life.
People use many different methods to fix this problem. It is common to use the antifogging technique, which is simple and easily applied. A variety of solvents, surfactants, dispersants, and wetting agents are all used in antifogging agent. While this anti-fogging agents is relatively easy to make, they are difficult to lose due to water condensation on the glass. The general anti-fog period is between 2-7 days. At the moment, there are no comparisons between the results of adding oxides in anti-fogging agents. Photocatalytic TiO2 is one of the most popular anti-fog films. Nano-titanium dioxide can diffuse small water droplets onto the glass surface and create a uniform film. This surface is not susceptible to light scattering fog. It can also maintain high transparency levels without burning. Use safely This anti-fog material is safe. It has excellent abrasion resistance.
Nano-cerium Oxide Glass Antifogging Medic
Its special surface effects and volume effects determine the special chemical properties of nanocerium oxide particles and their special effects. This includes enhancing the surface adsorption of nano-cerium oxide particles, increasing chemical reaction activity and surface active centres, as well as increasing surface activity. It also has high catalytic performances. The light it emits has both a catalytic and hydrophilic function. An ultrafine CeO2 particle can be added to anti-fogging. This will increase the agent’s surface adsorption. It also can absorb ultraviolet light which helps prevent them from rays. Finally, the CeO2 can act as a photocatalyst and can even help the organic crystals on the glass surface.
A new form of cerium dioxide glass antifogging agents with good antifogging effects, long antifogging times, stability, safety, and harmless production has been developed using nano-rare Earth ceriumoxid as a raw materials.
Add a little cerium oxide to a cup of concentrated HNO3 or H2O2 to dissolve. Prepare a 0.5mol/LCeNO33 aqueous mixture and heat slowly. When the temperature reaches above 180 degrees, it will evaporate to create a brown aerogel. This is used to produce nano-CeO2 powder.
The Preparation Method Of Nano Cerium Oxide Antfogging Agent
Use appropriate dispersants, surfactants, additives, nano-CeO2 and solvents to combine the antifogging agent. The single factor optimization method is used to run experiments and obtain the most effective formula.
