Q：What Are Acid Resistant Bricks Used For?
Common applications include chemical storage tanks, reaction tanks, acid pickling areas, wastewater treatment facilities, drainage channels, and industrial floors. The appropriate brick type depends on the chemical media, concentration, operating temperature, and exposure conditions.
Q: Which Acid Resistant Bricks Are Suitable for Sulfuric Acid?
The complete lining system, including the mortar and joints, must also be compatible with the process environment. Share your sulfuric acid concentration, operating temperature, and application details with REBO for a more appropriate material recommendation.
Q: What Is the Difference Between Acid Resistant Bricks and Acid Proof Tiles?
Bricks are commonly used in industrial tanks, pits, and heavy-duty lining systems, while tiles are often selected for floors, walls, and channels requiring a tiled lining. The best option depends on the application, mechanical loads, and lining design. See more different pictures on REBO Pinterest.
Q：What Thickness/Spec Should I Choose for My Industrial Plant (E.G., Chemical Plant, Electroplating Shop)?
| Application Area | Recommended Spec | Key Focus |
|---|---|---|
| General walkways & light-traffic areas | 20–30 mm thick | Standard tiles are sufficient |
| Heavy-load aisles & equipment foundations | ≥ 30 mm (up to 65 mm) heavy-duty bricks | Must meet ≥100 MPa compressive strength |
| Acid storage tanks & pickling tank linings | ≥ 30 mm, with high acid resistance | Prioritize water absorption ≤ 0.2% |
Q：What Are the Must-Check Technical Specs for Acid Resistant Bricks?
| Parameter | Standard Requirement | Why It Matters |
|---|---|---|
| Acid Resistance | ≥ 99.7% – 99.8% | The anti-corrosion specifications. Lower means the brick will degrade and powder under acid attack. |
| Water Absorption | ≤ 0.2% (for tanks/pits) | Lower is better. High absorption means pores allow acid to penetrate and corrode the substrate underneath. |
| Compressive Strength | ≥ 100 MPa (for heavy-load floors) | Determines if it can handle forklifts, heavy equipment, and impact loads without cracking. |
Q: What Is the Water Absorption Rate of Acid Proof Bricks?
Water absorption is an important indicator because it reflects how readily water can enter the material’s pores. However, low water absorption alone does not guarantee resistance to every chemical. Buyers should also evaluate acid resistance, mechanical strength, material composition, and compatibility with the intended operating environment. Always refer to the technical data for the specific product grade.
Q: How Can I Verify the Quality of Acid Proof Bricks Before Purchase?
ou can also request relevant quality certificates, inspection records, and pre-shipment inspection arrangements. Make sure the supplied products meet the agreed specifications and are suitable for the chemicals and operating conditions at your facility.
Q: How Can I Quickly Check the Quality of Acid Proof Bricks on Site?
The “Ring” Test: Tap the brick gently and listen to the sound. An unusually dull sound may indicate a defect, but sound alone cannot confirm product quality.
The “Water Drop” Test: Observe how a water drop behaves on the brick surface. This can provide a rough indication of surface wetting, but it cannot reliably establish the water absorption rate.
Weight and Cross-Section: Check whether the bricks have consistent dimensions, weight, and a uniform cross-section. Visible cracks, pits, or irregularities may warrant further inspection.
These checks are only preliminary screening methods. For final acceptance, rely on the agreed technical specifications, appropriate laboratory test results, and batch inspection reports.
Q: Can Acid Proof Brick Be Customized to Project Drawings?
Straight bricks, wedge-shaped bricks, and other specially shaped units can be considered for different lining structures. Provide your drawings, dimensions, required quantities, and application details so REBO can assess the manufacturing requirements.
Q: Which Mortar Should Be Used With Acid Resistant Bricks?
Depending on the application, suitable options may include potassium silicate mortar or resin-based mortars, such as furan resin mortar. Chemical concentration, temperature, moisture, and curing conditions should be evaluated before selecting the mortar. Ordinary cement mortar should not be assumed suitable for acid-resistant lining applications.
Q: Do You Supply Acid Proof Bricks and Compatible Mortar Together?
Selecting the bricks and mortar together helps ensure that the materials are appropriate for the intended application. Share your process conditions and project requirements so the suitable combination can be evaluated.
Q: How Much Do Acid Resistant Bricks Cost?
The total lining cost may also include compatible acid-resistant mortar, surface preparation, installation, and transportation. Contact REBO with your specifications and estimated quantity for a project-specific quotation.
Q: What Information Do I Need to Provide to Get a Quotation?
Chemical media and concentration;
Operating temperature and exposure conditions;
Application area, such as a tank, floor, pit, or drainage channel;
Required brick dimensions, shape, and lining thickness;
Estimated quantity;
Delivery destination and required delivery date;
Project drawings or site photos, if available.
With this information, REBO can evaluate your requirements and recommend suitable products and compatible mortar for your project.
Q: What Is the Lead Time for Acid Proof Brick Orders?
Standard products and customized shapes may have different production timelines. Contact REBO with your required specifications and delivery schedule to confirm the estimated lead time for your order.
Q: Do You Provide Technical Support for Acid Proof Brick Installation?
Depending on the project, support may include product drawings, installation instructions, and remote technical guidance. Installation methods should be determined according to the site conditions, substrate requirements, selected materials, and project specifications.
Q: How Long Do Acid Proof Brick Last?
Correct material selection and proper installation can help extend the service life. Regular inspection of brick surfaces, mortar joints, and damaged areas can help identify problems before they cause more extensive lining failure.
