Types of Acid Proof Mortar
Furan Resin Mortar
Furan resin mortar consists of furan resin liquid and furan powder. Mix the two components at a 1:3 ratio for use under normal temperature and humidity. For special humidity conditions, please consult REBO in advance. Furan resin mortar mainly includes YJ-2 and YJ-5. Both resist strong oxidizing acids poorly.
- YJ-2 resists various acids and alkalis and works at temperatures up to 150°C.
- YJ-5 resists HF.
Parameter of KP1 Silicate Mortar
KP1 Mortar consists of powder and liquid. Mix the powder and liquid at the specified ratio before use. Under normal temperature and humidity, the ratio is mortar powder:potassium silicate water glass=100:36-40. For special temperature and humidity conditions, please consult REBO in advance. KP1 mortar liquid mainly includes sodium silicate mortar and potassium silicate mortar.
- Sodium silicate mortar resists strong oxidizing acids.
- Potassium silicate is an improved version of sodium silicate, with better density, impermeability, and bond strength. It is not suitable for HF or hot concentrated phosphoric acid. It can be used in high-temperature flues above 150°C.
Acid Resistant Mortar Powder and Liquid Components
REBO acid proof mortar is supplied in separate powder and liquid components. Each component has a specific role and works together after mixing to form the final bonding mortar. Separate packaging helps maintain formulation stability, mixing accuracy, and consistent performance. The mixing ratio and application method vary by mortar type and service conditions. Contact REBO for the right acid proof mortar for your specific operating conditions.
| Component | Main Function | Package |
|---|---|---|
| Powder | Provide mineral fillers and solid materials for body and strength. | 25kg Double-Layer Woven Bag |
| Liquid | Provide the binder or resin phase for bonding and chemical resistance. | 250KG Iron Drum |
| Mixed Mortar | Form the final acid-resistant bonding layer between the substrate and brick or tile. | Mixed at the Construction Site |
Acid Proof Mortar vs Conventional Cement Mortar
Unlike ordinary cement mortar, which is restricted to general masonry and construction, acid-proof mortar is specifically engineered for industrial chemical environments. It delivers superior chemical and acid resistance with minimal penetration, offering the exceptional bonding capabilities required for brick and tile lining systems where conventional cement would quickly fail.
| Feature | Acid Proof Mortar | Ordinary Cement Mortar |
|---|---|---|
| Acid Resistance | Designed for corrosive media | Limited |
| Chemical Resistance | High for suitable media | Limited |
| Water/Chemical Penetration | Lower for suitable systems | Higher |
| Bonding to Acid Resistant Linings | Designed for lining systems | General construction |
| Industrial Chemical Applications | Yes | Generally unsuitable |
| Lining System Use | Brick+Tile+Mortar | General masonry |
How to Choose the Right Acid Proof Resistant Cement Mortar
To ensure the long-term reliability of your anti-corrosion system, selecting the correct REBO chemical resistant mortar requires precise operational data. When consulting with our engineering team, please provide your specific chemical media, concentration levels, operating temperatures, lining materials (such as acid resistant bricks or acid resistant carbon bricks), application areas (tanks, floors, or channels), and exposure conditions like immersion or thermal cycling. Sharing these exact parameters allows us to formulate or recommend the ideal mortar solution tailored precisely to your industrial environment.
| Selection Factor | What to Provide | Why It Matters |
|---|---|---|
| Chemical Media | H₂SO₄, HCl, H₃PO₄, HF, organic acids, alkalis | Determines chemical compatibility |
| Concentration | e.g. 20%, 50%, 98% | Higher concentrations may require different mortar formulations |
| Operating Temperature | e.g. 60°C, 100°C, 150°C | Determines the suitable temperature range |
| Lining Material | Acid Resistant Brick, Acid Proof Tile, Anti-Corrosion Carbon Brick | Affects bonding and system compatibility |
| Application Area | Tank, Floor, Channel, Scrubber, Pipe | Determines bonding, mechanical, and installation requirements |
| Operating Conditions | Immersion, Splash, Continuous Contact, Thermal Cycling | Affects chemical exposure and long-term performance |
