Acid Proof Brick

Acid proof brick is made of high quality high silica acid resistance material, which can effectively resist to the corrosion of high sulfur gas , widely used in electric power, petrifaction, chimneys of metallurgy and other thermal equipment, and the liners of flue and easy-corrosive liners.

Characteristics:
1.Anti-corrosion by acids, alkalis, oxidants and solvents.
2.Good resistance to mechanical and physical shocks.
3.Cost-efficient

Application:
Refractory and acid-resistant bricks are mainly used in acid regeneration roasting furnaces ,coke oven, and other kilns for smelting industry.
