Acid Proof Brick Lining

Acid-resistant brick lining is a protective layer used in various industrial applications where chemical resistance is crucial. Let me provide you with some details:

1. Purpose and Application:

• Acid-resistant lining is applied to surfaces like floors, tanks, brick and tile linings, and drains where maximum chemical resistance is required.
• Industries that benefit from acid-resistant lining include dyestuff, thermal power stations, fertilizers, and food processing1.

1. Materials Used:

• Acid-resistant bricks and tiles are commonly used for this purpose.
• These bricks and tiles are designed to withstand the corrosive effects of acids and other aggressive chemicals.

1. Features:

• Chemical Resistance: Acid-resistant lining provides efficient and lasting protection against corrosion.
• Impact and Scratch Resistance: It is durable and can withstand mechanical stress.
• Longevity: Properly installed acid-resistant lining does not deteriorate over time1.

Installing an acid-resistant brick lining involves several steps to ensure its effectiveness and longevity. Here’s a concise guide on how it’s done:

1. Surface Preparation:

• Clean the Surface: Ensure that the substrate (such as concrete, steel, or existing brickwork) is clean, dry, and free from dust, grease, or other contaminants.
• Roughen the Surface: Use mechanical methods (such as sandblasting) to create a rough texture. This enhances the bonding between the substrate and the acid-resistant bricks.

1. Selection of Acid-Resistant Bricks:

• Choose acid-resistant bricks made from materials like silica, fireclay, or vitrified clay. These bricks have excellent chemical resistance.
• The bricks should be of the appropriate size and shape for the specific application.

1. Brick Mortar Mix Preparation:

• Prepare an acid-resistant mortar mix. Commonly used mixtures include acid-resistant cement, silica sand, and additives.
• Follow manufacturer guidelines for the correct proportions.

1. Laying the Bricks:

• Start from the bottom and work upward.
• Apply a layer of mortar on the substrate using a trowel.
• Place the acid-resistant bricks in the mortar bed, ensuring proper alignment and spacing.
• Tap the bricks gently to set them in place.

1. Joint Filling:

• Fill the gaps between bricks with acid-resistant mortar.
• Use a pointing trowel to create smooth and uniform joints.
• Ensure that the joints are completely filled to prevent chemical penetration.

1. Curing and Drying:

• Allow the acid-resistant brick lining to cure. Follow the recommended curing time.
• Keep the area moist during curing to prevent premature drying.

1. Acid-Resistant Coating (Optional):

• Apply an acid-resistant coating over the brick surface for additional protection.
• Coatings can enhance chemical resistance and prevent surface erosion.

1. Quality Inspection:

• Inspect the installed lining for any defects, cracks, or unevenness.
• Address any issues promptly.

1. Final Checks:

• Check for proper alignment, joint integrity, and overall adherence.
• Ensure that the acid-resistant brick lining meets the required specifications.

Remember that proper installation is critical for the long-term performance of acid-resistant brick linings. Consulting with experienced professionals ensures a successful application in corrosive environments.
