Acid Resistant Tiles
Acid resistant tiles are special ceramic materials designed for harsh acid environments. These tiles achieve dense structures through high-temperature sintering. Therefore, they provide long-lasting protection. As a manufacturer, Kerui offers multiple standard sizes. Additionally, we deliver strong customization capabilities. Currently, we serve over 100 customers including chemical plants, wastewater treatment and other facilities.

- Process Basis:: 1200℃ high-temperature sintering to form glass-phase sealed micropores;
- Excellent Thermal Stability: No cracks after multiple water cooling cycles;
- Mechanical Strength Guarantee: Pressure bearing capacity with flexural strength ≥58.8 MPa;
- Safety and Environmental Protection Characteristics: Heavy metal dissolution is lower than the conventional standard;
- Long Service Life:: Typical service life in chemical environment is long.
Application Scenarios and Industry Solutions of Acid Resistant Tiles
Masonry linings: As reliable acid proof tiles suppliers, Kerui provides masonry linings for reaction vessels and acid storage facilities, including tanks, ditches, and wells—engineered,
Workshop Floor: Use acid proof tiles in strong acid production workshop floor paving to protect against acidic liquid splashing and gas condensation corrosion.
Pickling Process area: The inner wall and bottom of the steel pickling tank are paved to withstand long-term immersion and mechanical scouring of hydrochloric acid and nitric acid.
Electroplating Workshop Protection: Floor paving to resist leakage of cyanide and sulfuric acid electroplating liquid, taking into account wear resistance requirements.
Wastewater Treatment Facilities: Acidic wastewater regulating tank, neutralization tank, sedimentation tank lining to resist mixed acid, alkali and organic corrosion.
Landfill: Use products for protective layer of anti-seepage pool and diversion ditch to prevent acidic leachate from eroding soil structure.
Food Processing Area: The floor of the pickling and fermentation workshops is protected from acetic acid and citric acid, and the surface is smooth and easy to clean.
Pharmaceutical Workshop: The operation table and floor in the drug synthesis area are resistant to organic solvents and acidic reagents.
Power Plant Desulfurization system: Acid proof tiles for battery room applications, wet desulfurization absorption tower and slurry pool lining are resistant to corrosion by sulfur-containing slurry.
Chemical Power Plant: The floor protection of coal-to-gas workshops is resistant to condensation of acidic gases such as sulfur dioxide.
Laboratories and Scientific Research Sites: The floor and laboratory bench of the chemical laboratory are protected from splashing of strong acid reagents.
Acidic Soil Buildings: The bottom layer of buildings in acidic areas is protected to block the penetration of acidic substances.
