Acid Proof Brick

Description

Acid Proof Brick Introduce
 
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.

Acid Resistant Brick Feature 

1. Good acid resistant.
2. High strength and Wear resistance.
3. Low water absorption and low apparent porosity.
4. Good eroding proofing and impact resistance.
5. High temperature resistant.
6.Good thermal shock resistance.
7. High mechanical strength.
