Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

Specification of silica fume for asphalt 25kg bag densified hydrophilic fumed (hdk n20) chemie 99.99999

This silica fume is for asphalt work. It comes in 25kg bags. The material is densified. This makes it less complicated to deal with. It is hydrophilic fumed silica. Water mixes well with it. The product kind is HDK N20. Its purity is exceptionally high, 99.99999%. This implies really few impurities exist. The silica fume is a by-product. It comes from silicon metal production. The bits are extremely small. They are much finer than cement. This excellence gives it special residential properties. Including this silica fume improves asphalt. The asphalt mix becomes more powerful. It stands up to deformation better. Pavements last longer. Rutting reduces significantly. This is the long-term grooves in roads. The asphalt combination additionally gets toughness. It holds up against weather condition damage much better. Freeze-thaw cycles cause less injury. Fracturing is much less most likely. The silica fume loads little gaps. It creates a denser asphalt structure. Dampness penetration lowers. This secures the asphalt from inside damage. The hydrophilic nature is very important. It ensures good diffusion in damp blends. The material incorporates efficiently. Workability remains sensible. The densified form offers benefits. It flows well. It pours conveniently from bags. Dirt production is lessened. This is more secure for employees. The high purity ensures constant efficiency. Unwanted aspects will not conflict. They will not damage the asphalt. This silica fume is an effective additive. It upgrades asphalt top quality considerably. Usage correct safety and security gear. Silica dust requires careful handling. Wear a respirator mask. Use safety gloves. Great ventilation is crucial. Comply with all security guidelines strictly. Store bags in a dry place. Maintain them far from wetness.

Applications of silica fume for asphalt 25kg bag densified hydrophilic fumed (hdk n20) chemie 99.99999

This silica fume is for asphalt. It can be found in 25kg bags. The item is compressed hydrophilic fumed silica (HDK N20) Chemie grade. It is exceptionally pure. This pureness matters for efficiency.

Including this silica fume makes asphalt much better. It makes the mix much denser. A denser mix is stronger. It resists rutting much better. Rutting is when wheels make grooves in the road. Nobody wants that. The sidewalk stays smoother much longer.

It also combats splitting. Asphalt obtains brittle over time. Temperature level changes create stress and anxiety. This silica fume aids the binder hold with each other. It minimizes fracturing from winter. It lowers fracturing from obtaining old. Roads last much longer prior to requiring repair work.

Water damage is a huge problem. Water leaks right into fractures. It deteriorates the base under the asphalt. This results in pockets. This silica fume makes asphalt much less permeable. Water can not permeate as easily. This protects the sidewalk structure underneath. It conserves money on upkeep.

The densified type is simple to manage. The 25kg bags are convenient. The hydrophilic nature means it mixes well with the asphalt binder. There are no clumping troubles. Employees can add it straight to the plant mixer. Comply with the provider’s dosage suggestions. Storage is basic. Maintain the bags dry and sealed until use. Stay clear of breathing the dirt. Wear a dirt mask throughout handling. Comply with conventional silica safety and security treatments.

5 FAQs of silica fume for asphalt 25kg bag densified hydrophilic fumed (hdk n20) chemie 99.99999

What is silica fume? Silica fume is a very fine powder. It comes from making silicon metal. This powder is super small particles. It makes asphalt stronger and last longer.

Why use silica fume in asphalt? Adding silica fume makes asphalt better. It helps the asphalt mix stick together well. This makes roads tougher. Roads resist cracking and rutting. The asphalt lasts longer under heavy traffic and weather.

How much silica fume goes into asphalt? Use a little bit. A common amount is 0.5% to 1.5% by weight of the asphalt binder. For one ton of asphalt binder, add roughly 10 to 30 pounds of silica fume. Follow your mix design instructions carefully. Too much isn’t helpful.

Why choose this HDK N20 silica fume? This HDK N20 type is densified. It is compacted into grains. This makes it easier to handle than fluffy powder. It is hydrophilic. This means it attracts water and mixes well with liquid asphalt. The 99.99999% purity means it’s very clean. This ensures consistent performance in your asphalt mix.

How do I handle and store this silica fume? Keep the sealed 25kg bags dry. Store them indoors on pallets. Keep them off wet floors. Protect bags from rain and moisture. Wear a dust mask when opening bags. Avoid breathing in the fine dust. Use gloves and eye protection. Silica fume is stable. Stored correctly, it lasts a long time.
