Acid-resistant brick
Application Industry: Refractories for Power and Petrochemical Industry
Application Equipment: Acid Regeneration Process Furnace Lining and Other Acid-Corrosion Furnaces
Size: Custom acid-resistant brick geometry per acid regeneration process furnace design (free engineering on request)
Products Overview
Our Acid-resistant brick is a high-performance refractory brick product engineered for acid regeneration process furnace lining and other acid-corrosion furnace service in power and petrochemical industry. The acid-resistant refractory bricks produced by our company adopt high-grade refractory aggregates, powders, additives, and so on. After reasonable grading and high temperature firing, they can fully meet the acid and high temperature resistance of furnace lining refractories under various acid regeneration process conditions. The acid-resistant brick has high strength, anti-scour, long life and other features for power and petrochemical industry service.
The Acid-resistant brick product family is offered in three engineering-proven NSZ chemistry grades. The CH-NSZ1.0 grade features Bulk Density maximum 1.0 g/cm3 for general acid regeneration process furnace lining service, with Water Absorption maximum 15 percent, Cold Crushing Strength minimum 10 MPa, Acid Proof minimum 96 percent, and Heating Line Change maximum 0.1 percent at 300 °C. The CH-NSZ1.3 grade features Bulk Density maximum 1.3 g/cm3 for higher-demand acid regeneration process furnace lining service, with Water Absorption maximum 13 percent, Cold Crushing Strength minimum 15 MPa, Acid Proof minimum 96 percent, and Heating Line Change maximum 0.1 percent at 300 °C. The CH-NSZ1.8 grade features Bulk Density maximum 1.8 g/cm3 for highest-demand acid regeneration process furnace lining service, with Water Absorption maximum 12 percent, Cold Crushing Strength minimum 20 MPa, Acid Proof minimum 96 percent, and Heating Line Change maximum 0.1 percent at 300 °C.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Acid-resistant brick grade is engineered to ASTM, GB/T, and ISO refractory standards.
