Application of Aerogel Coating in Thermal Insulation for Metal Chemical Storage Tanks

Description of Metal Chemical Storage Tanks
Chemical storage tanks are essential for storing raw materials and processing them into specified products. Semi-finished and finished chemical products rely on these tanks for processing. In particular, for metallic chemical storage tanks designed to prevent low temperatures or condensation, effective insulation during winter is crucial. Inadequate insulation can lead to chemical materials becoming non-flowable or unusable, ultimately causing production shutdowns.
Current Status and Issues in Tank Insulation
Taking oil storage tanks as an example, the current insulation of the outer walls typically involves a fixed structure using angle steel and flat steel, with insulation materials secured using steel strips. The final step includes installing a metal protective layer. Common insulation materials include rock wool, mineral wool, and silicate materials. Over long-term use, this insulation structure faces several problems:
- Under the influence of wind force, some protective layers may detach or develop edge openings due to improper construction, leading to water ingress into the insulation layer.
- Traditional insulation materials have a porous structure, making them prone to water absorption and failure, resulting in decreased insulation effectiveness and a shorter lifespan.
- Water ingress into the insulation layer creates a moisture-sealed system beneath the protective layer, accelerating corrosion below the insulation layer. This is particularly problematic in areas where accessories like thermocouples, thermometers, and safety valves are installed on the pipe walls.
- Due to limitations in traditional insulation materials, tank tops are generally left uninsulated, causing significant heat dissipation issues, especially in floating roof tanks where the proportion of heat dissipation area on the tank top increases when the tank is not fully filled.
In situations where traditional insulation materials cannot address these issues, it is recommended to use the aerogel insulation coating system for tank insulation.
Advantages of Aerogel Coating in Industrial Tank Insulation
The Anchor-tech aerogel insulation coating system consists of water-based multifunctional primer + aerogel insulation intermediate coating + water-based solar reflective topcoat.
- Thermal Insulation Performance: The ANCHOR-TECH aerogel insulation intermediate coating effectively reduces heat conduction, providing excellent thermal insulation performance.
- Reflectivity and Corrosion Resistance: The ANCHOR-TECH water-based solar reflective topcoat has high reflectivity and emissivity, reducing solar radiation absorption and offering superior thermal insulation. The entire coating system works synergistically to ensure excellent thermal insulation effectiveness. The ANCHOR-TECH water-based multifunctional primer has high acid and alkali resistance, acting as a corrosion-resistant layer.
- Hydrophobicity: The aerogel insulation coating exhibits good hydrophobicity, effectively preventing the corrosion issues observed in traditional materials beneath the insulation layer.
- Fire Performance: The combustion performance meets A2-level fire resistance.
- Anti-Staining Performance: The coating itself has self-cleaning ability, maintaining an aesthetically pleasing appearance over an extended period.
- Environmental Performance: All materials used are non-toxic and environmentally friendly, causing no pollution harm to the environment.
Additionally, using the aerogel insulation coating system can effectively address tank top heat dissipation issues, reducing construction difficulty.
In summary, replacing traditional insulation structures with the aerogel insulation coating system for tank insulation offers energy efficiency, effectiveness, and environmental benefits. This solution effectively addresses issues associated with traditional insulation materials, such as poor insulation performance and corrosion beneath the insulation layer.
