• It is also highly resistant to fire, which makes it an ideal choice for fireproofing.
• it is highly durable. It is able to withstand extreme temperatures and other environmental conditions without breaking down.
• It is resistant to corrosion, making it an ideal choice for use in areas where corrosion is a concern.
• Silica fume is also cost-effective. It is relatively inexpensive compared to other insulation materials, making it an ideal choice for those looking to save money.

Overall, microsilica fume is an excellent choice for thermal insulation materials. It is highly effective at preventing heat transfer, durable, and cost-effective.

Silica fume applications in different industry types

1. Application in the cold chain industry

The cold chain industry is vital to the global food supply chain. It is responsible for transporting food products from farm to market, ensuring they remain fresh and safe for consumption. The cold chain industry relies on various materials and technologies to keep food products at the right temperature throughout their journey. Insulation is one of the most critical materials in the cold chain industry. Insulation helps reduce the amount of heat transferred between the environment and the food products during transportation. This helps to keep food products at a safe temperature, preventing spoilage and contamination. Micro silica fume has many advantages over traditional insulation materials. It is light in weight, easy to install, and has low thermal conductivity. This means that it can keep the temperature of the cargo at a more consistent level, reducing the risk of spoilage or damage. Additionally, it is highly resistant to corrosion and can withstand extreme temperatures and moisture conditions. It is also non-toxic and non-flammable, making it a safe choice for use in the transportation of food and other sensitive items.

2. Application in the construction industry

In the building, micro silica silicate thermal insulation coating is mainly used to insulate internal and external walls. It is usually a fiber-thickened paste that is applied onto the wall surface, and after drying, it gives a strong and flexible insulation layer. It has low thermal conductivity, easy installation, cost-effectiveness, and remarkable heat conservation properties. Furthermore, due to its low thermal conductivity, good insulation, and remarkable thermal insulation properties, the micro silica fume silicate composite thermal insulation wall coating has a high bonding strength, tensile strength, and shear strength and is widely used.

3. Application in power generation

Thermal insulation is critical in power plants, particularly thermal, nuclear, or geothermal energy. It helps save energy, reduce heat loss, adhere to production process requirements, guarantee equipment and personnel safety, and enhance economic and environmental benefits. Silicate composite thermal insulation coatings with micro silica fume are effective for irregularly-shaped components such as valves, elbows, cylinders, tanks, and containers.

4. Application of the cement industry

The microsilica composite silicate thermal insulation coating is applied to the dryer cylinder’s surface, reducing heat loss by over 80%. Additionally, the inner wall of the cylinder avoids moisture build-up and preserves the drying state, thus preventing blockage and acid corrosion, extending the cylinder’s service life. Furthermore, the drying output can increase by up to 15-20%, resulting in an even more visible energy-saving effect, and can be used in open-air pipelines.

5. Application in Food refrigeration

Vacuum insulation panels (VIP) with micro silica fume are a type of insulation material that is used in food refrigeration systems. It is a lightweight material that is highly effective in reducing the thermal conductivity of the refrigeration system. The micro silica fume is mixed with a binder to form a thin film that is then applied to the inner walls of the refrigeration system. This thin film acts as a barrier to the cold air, thus reducing the amount of energy needed to keep the food cold. The micro silica fume also helps reduce the amount of moisture released into the refrigeration system, which helps to minimize the growth of bacteria and mold.

6. Application in the logistics industry (vaccine logistics)

Micro silica fume is an excellent addition to the cold chain of vaccine logistics. It is a highly absorbent material that can keep vaccines and other temperature-sensitive materials cold and safe for an extended period. Micro silica fume is non-toxic and non-flammable, making it an ideal material for the cold chain. It is also lightweight and easy to transport, making it ideal for vaccine distribution. Finally, micro silica fume can absorb moisture, which helps prevent the vaccines from spoiling. Thus, micro silica fume is an essential part of the cold chain that must remain intact to ensure vaccine delivery.

Application of Silica Fume in Thermal Insulation Materials

The application of Silica fume in thermal insulation materials has several advantages:

• It increases the thermal resistance, making it more effective at preventing heat transfer.
• It improves the material’s fire resistance, making it more resistant to fire and heat.
• It increases the material’s durability, making it more resistant to wear and tear.
• It is highly porous, allowing it to absorb and retain moisture, which can help to reduce condensation.
• It has a high surface area, which makes it an effective adsorbent for pollutants. This can help reduce the number of pollutants released into the environment.

Silica fume is an effective way to improve the thermal insulation properties of materials while also providing additional benefits such as fire resistance and pollutant absorption. As energy efficiency standards become more stringent, the use of microsilica fume in thermal insulation materials is likely to become even more widespread.
