Core Functions of Acid-Resistant Bricks in Tank Farm Protection
- Corrosion Resistance: The Acid-Resistant Bricks contain over 70% silica, forming a dense structure through high-temperature firing. They effectively resist most acids like hydrochloric, sulfuric, and nitric acids, as well as normal temperature alkalis, except hydrofluoric acid, hot phosphoric acid, and concentrated alkalis. Their low water absorption rate prevents medium penetration and material contamination.
- Structural Protection: With high compressive strength and wear resistance, they shield tank bases and walls from mechanical damage and chemical erosion, extending facility lifespan.
Key Application Advantages in Tank Farm Scenarios
- Acid Waste Containment: Ideal for lining acid-neutralization pits and wastewater treatment tanks, preventing corrosive leaks.
- Chemical Compatibility: Suitable for storage areas handling acidic cleaning agents or process fluids, common in food, dairy, and chemical plants.
- Durability in Harsh Environments: Withstands temperature fluctuations and humid conditions when properly installed with epoxy or acid-resistant mortar.
Construction Requirements for Optimal Performance
- Surface Preparation: Concrete substrates must be cleaned with oxalic acid to neutralize alkalis before brick installation.
- Installation Specifications:
- Use acid-resistant mortar with 8-10mm joint width, ensuring depth matches brick thickness.
- Post-installation acid washing enhances joint sealing and adhesion.
- Environmental Controls:
Industry-Proven Effectiveness
Widely adopted in petroleum, chemical, pharmaceutical, and wastewater treatment facilities, acid-resistant bricks provide a cost-effective, long-term solution for tank farm corrosion management. Their non-porous surface also facilitates easy cleaning, maintaining hygiene standards in sensitive industries like food processing.
