Types of Acid Alkali Proof Tile
REBO high-performance acid alkali resistant tiles available in unglazed, glazed, grooved, and custom variations are engineered from premium raw materials including quartz, feldspar, and clay. Through high-temperature oxidation and decomposition, these materials create an exceptionally durable, low-maintenance barrier boasting 99.8% acid resistance and 0.2% water absorption. Except for hydrofluoric and hot phosphoric acids, REBO tiles deliver superior corrosion resistance against any concentration of acids and weak alkalis. It makes them the ultimate factory-direct solution for high-acid environments, underground sewers, and open-air industrial grounds. It is different from acid resistant bricks.

- 20mm (Standard Duty): Engineered for general flooring with ambient temperature, mild corrosion, and standard walls.
- 30mm (Heavy Duty): Perfect for pickling tank inner walls, regular heavy-traffic industrial workshops, and drainage trenches.
- 40/50mm (Extreme Duty): Designed for pickling tank bottoms, heavy forklift zones, fertilizer handling bays, and high-impact discharge outlets.
| Thickness 15mm | Thickness 20mm | Thickness 30mm |
|---|---|---|
| 150*150*15;200*200*15; 300*300*15;300*600*15; 600*600*15; |

Acid & Alkali Resistance Capabilities
| Media Type | Examples | Resistance | Application Notes |
|---|---|---|---|
| Inorganic Strong Acids | Sulfuric (H2SO4), Hydrochloric (HCl), Nitric (HNO3), Phosphoric (H3PO4) | Excellent | Long-term resistance to full concentration at ambient to medium temperatures. |
| Organic Acids | Acetic, Oxalic, Citric, Lactic, Formic, etc. | Excellent | Ideal for food, pharmaceutical, and chemical processing. |
| Acidic Gases & Salts | SO2, Cl2, Sulfates, Chlorides | Excellent | Ultra-low water absorption (≤0.2%) prevents liquid penetration and salt crystallization. |
| Weak/Dilute Alkalis | Dilute NaOH, Dilute KOH, Ammonia | Limited | Ambient temperature and low concentration only. |
| Hydrofluoric Acid | Hydrofluoric Acid (HF) | DO NOT USE | No resistance. HF rapidly dissolves the SiO2 structure. |
| Strong / Hot Alkalis | Hot concentrated NaOH, molten alkalis | DO NOT USE | No resistance. Hot alkalis degrade the silica-alumina base, causing peeling. |

Acid and Alkali Resistant Tiles Guarantee Your Projects’ Safety
Acid Alkali Resistant Tiles Manufacturers
REBO is a leading high-tech enterprise dedicated to the research, development, manufacture of chemical-resistant materials, and specialized anticorrosion engineering construction. Operating from a 100,000-square-meter state-of-the-art facility with a dedicated team of 200 professionals (including 15% R&D experts), we run 4 fully automated production lines yielding an annual capacity of over 2,000,000 square meters of acid-alkali proof tiles.
Our advanced formulation combines high-purity silica (SiO2) with specialized anti-alkali modifiers. This unique matrix creates an incredibly dense chemical barrier, guaranteeing an authoritative acid resistance of 99.8% while preventing cyclic erosion.
Every REBO tile is forged under heavy-duty, high-tonnage automated hydraulic presses. This extreme compaction completely eliminates internal micro-pores and capillaries, lowering the water absorption rate to an ultra-low, leak-proof 0.2%.
Our facility operates computer-controlled tunnel kilns that maintain strict, uniform firing temperatures 24/7. This precise vitrification process ensures ultimate structural density, giving tiles maximum load-bearing and thermal shock resistance.
Backed by rich engineering expertise and an agile OEM/ODM framework, we provide tailored shapes, sizes, and thicknesses. We build custom molds for non-standard structures like curved tanks and chimneys, ensuring a perfect 1:1 installation fit.
