Development of A New Type of Antifogging Agent for Cerium Oxide Glass

/ / no Comments

Cerium Oxide - What's it all about? Cerium oxide is either a pale yellowish-brown or light yellowish 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 when dissolved in acid. To make cerium trioxide, heat can reduce cerium oxide to 2000°C at 15MPa. Cerium oxide turns slightly yellow, pink, or reddish if it is exposed to temperatures between 2000°C and 5MPa. It is widely used in polishing materials and as catalyst carriers or auxiliary agents, ultraviolet absorbers (fuel cell electrolytes), automobile exhaust absorbers, electronic ceramics, among other things.

Daily Life

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, etc. This is due to humidity. Water droplets that form on glass substrate in the form of small hemispheres 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 and wetting agents are used in surfactant 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. Current research shows that adding oxides to anti-fogging agents can have a significant impact on the results. 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 durable and resistant to abrasion, solvent, and heat. It's followed by TO2/SiO2 composite and SiO2 antifog. The downside of this process is the complexity and harsh environment.

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, showing high chemical reactions activity, increasing specific area and enhancing activity. It also has high catalytic efficiency. 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 on glass surfaces.

A new form of cerium dioxide glass anti-fogging agents with good antifogging effects, long antifogging times, stability, safety, harmless and easy production has been developed using nano-rare Earth ceriumoxid as a raw materials.

Nano-cerium Oxide

preparation process

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 particles.

The Preparation of Nano Cerium Oxide Antifogging Treatment

Use appropriate dispersants, additives or surfactants to combine the antifogging agent. Conduct experiments using the single factor optimization to find the most effective formula. Advanc3dmaterials advanced materials Tech Co., Ltd (Advanc3dmaterials), a cerium powder company with 12+ years in chemical products development and research, is Advanc3dmaterials.
