Overview of Silica aerogel

Definition: Silica aerogel is a solid material derived from a gel, in which the liquid component of the gel has been replaced with a gas. This process results in a material that retains its gel-like structure but is extremely lightweight.

Production: It is typically produced through a sol-gel process followed by supercritical drying, which removes the liquid without causing the solid structure to collapse.

Applications: Commonly used in aerospace applications, as insulation in buildings, pipelines, and oil and gas industries due to its remarkable insulative properties.

Features of Silica aerogel

Low Density: One of the lightest solid materials known, often lighter than air, giving it a ghostly appearance.

Thermal Insulation: Possesses extremely low thermal conductivity, making it an excellent insulator even at high temperatures.

Transparency: Depending on its thickness and processing, silica aerogels can be highly transparent, allowing them to be used in certain optical applications.

Hydrophobicity: Many types of silica aerogels are treated to become hydrophobic, which helps prevent moisture absorption and enhances their durability and insulation performance.

Mechanical Fragility: Despite its impressive properties, silica aerogel is quite brittle and requires careful handling to avoid damage.

Specification of Silica Aerogel of Silicon Dioxide For Vacuum Insulation Panel

Silica aerogel supplies the core insulation inside vacuum insulation panels. This material is primarily silicon dioxide. It has an extremely porous structure. The tiny pores are nanometers in dimension. This special framework is key to its performance.

The aerogel powder made use of in VIPs is really light. Its density is generally low, often around 180kg per cubic meter. This agility adds to the panel’s general performance. The powder fills the panel envelope completely. This stops warmth relocating with the air inside.

Its thermal efficiency is impressive. The nanoporous framework obstructs warmth transfer courses efficiently. This keeps warmth transfer extremely reduced. Under vacuum, its thermal conductivity comes to be exceptionally low. Values are typically listed below 0.004 W/mK. This makes it better than typical insulation like foam or fiberglass.

The particle dimension of the aerogel powder matters. Fine bits compact densely. This minimizes voids in between fragments. Smaller sized gaps mean less heat can relocate with transmission. Common particle sizes range from microns to nanometers. The specific size affects the final insulation worth.

Silica aerogel is chemically steady. It does not respond conveniently with various other materials. This stability is very important inside the secured VIP. It guarantees long-lasting performance. The material additionally handles temperature changes well. It works properly throughout a variety.

Its reduced density helps maintain the whole panel thin. This is a major benefit where room is limited. Home builders and engineers worth this space-saving residential property. The high performance allows thinner wall surfaces without shedding insulation high quality. This material satisfies demanding energy efficiency requirements.

Applications of Silica Aerogel of Silicon Dioxide For Vacuum Insulation Panel

Silica aerogel made from silicon dioxide gives the core product for high efficiency vacuum insulation panels. This product includes a very porous framework. Many little holes exist inside it. The holes gauge just nanometers throughout. This special structure catches air particles effectively. Caught air particles can not move openly. Warm transfer via conduction lowers greatly consequently. The vacuum inside the panel eliminates most remaining gas. This combination accomplishes exceptional thermal resistance. Vacuum insulation panels utilizing silica aerogel cores provide remarkably reduced thermal conductivity. Values usually drop between 0.004 and 0.008 W/m · K. This efficiency exceeds typical insulation like foam or fiberglass substantially. Thinner insulation layers come to be feasible. Conserving space is a significant advantage. These panels work well where space is restricted. Typical applications include refrigerators, freezers, and cold chain product packaging. The building market uses them too. They insulate wall surfaces, roofings, and special frontage aspects efficiently. Slim profiles are achievable. Lowering heat loss without thick layers matters. The electronics area employs these panels. Protecting sensitive devices from temperature extremes is crucial. Silica aerogel cores withstand compression under vacuum. Preserving panel integrity in time is essential. Long-term insulation performance remains trusted. Longevity supports different demanding uses. The material takes care of temperature level variations well. Security across a broad array is crucial. Fire security is another favorable facet. Silica aerogel is inherently non-combustible. This property adds worth in building and appliance security standards. On the whole, vacuum cleaner insulation panels with silica aerogel provide premium thermal efficiency in very little thickness. Space financial savings and energy performance drive their adoption.

5 FAQs of Silica Aerogel of Silicon Dioxide For Vacuum Insulation Panel

Silica aerogel is silicon dioxide. It looks like solid smoke. People use it inside vacuum insulation panels. These panels need special core materials. Aerogel works well here.

What is silica aerogel?
Silica aerogel is mostly air. It’s a solid foam made from silicon dioxide. It has a lot of nano-sized pores. These pores trap air inside. This makes it super light and great for stopping heat.

Why use silica aerogel in VIPs?
Vacuum insulation panels need the best core. Aerogel has tiny pores. Small pores hold vacuum better. Air molecules struggle to move through them. This means the panel stays insulated longer. Heat transfer is very low.

How does the vacuum help?
Vacuum removes air molecules. Air molecules carry heat. Removing air stops heat moving through the panel. Aerogel’s structure holds the vacuum stable. The tiny pores prevent gas molecules from flowing easily. This keeps the insulation strong.

Are thinner panels possible?
Yes. Silica aerogel is very effective. You need less material to get the same insulation. This allows thinner vacuum panels. Thin panels save space. They are useful where space is limited.

Is silica aerogel expensive?
Currently, yes. Making silica aerogel costs more. Creating its nano-pore structure needs special equipment and processes. It is more expensive than some other core materials. But its performance is much higher. You get better insulation for the thickness.
