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

Cerium Oxide – What’s it all about? Cerium oxide is either a pale yellowish-brown or light yellowish powder. The bulk density is 7.13g/cm3, and the melting point at 2397. The boiling point is 3500. 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 is widely used in polishing materials and as catalyst carriers or auxiliary agents, ultraviolet absorbers (fuel cell electrolytes), automobile exhaust absorbers, electronic clays, and other applications.

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, and more. This is due to humidity. Water droplets that form on glass substrate in the shape 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 numerous 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. We are currently comparing the results from 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 good abrasion resistance as well as abrasion and solvent resistance. The next step is SiO2 antifog and TO2/SiO2 composted films. But, this process can prove difficult and challenging in harsh environments.

Nano-cerium Oxide Glass Antifogging Medic

Its special surface effects and volume effect determine the special chemical properties of nanocerium oxide particles and their special effects. This includes enhancing the surface adsorption of nano-cerium oxide particles, as well as showing high chemical reaction activities, increasing specific surface area and increasing surface active centres. 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.

A new form of cerium dioxide glass anti-fogging agents with good antifogging effects, long anti­fogging times, stability, safety, harmless and simple 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 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 to determine which formula yields the most effective.
