Acid resistance brick is made of high-quality high silica acid resistance material, which can effectively resist the corrosion of high sulfur gas, acid resistance bricks are widely used in electric power, petrifaction, chimneys of metallurgy and other thermal equipment, and the liners of the flue and easy-corrosive liners.
Description of Acid Resistance Brick
There are two kinds of acid resistance brick, one is with glaze, the other is without the glaze. The main material of acid proof brick is quartz, feldspar, and clay, it is a kind of anti-corrosive material by high-temperature oxygenolysis. It has the characteristics of high acid resistance, low water absorption, not easy to be oxidized at normal temperature, not easy to be polluted by the medium. Except for the hydrofluoric acid and hot phosphoric acid, it has excellent anticorrosive properties to wet chlorine, saline water, hydrochloric acid, sulphuric acid, hydrogen nitrate, and other acid and any concentration alkaline at normal temperature.
Application of Acid Resistance Bricks
The acid resistance brick can be widely applied to the lining construction of the tower, pool, tank, the groove of the petroleum, chemical industry, chemical fertilizer, pharmacy, brewing, dairy product, paper making, smelt, chemical fiber and electroplating, chemical laboratory, electricity generation, gas, and other industry.
Features of Acid Resistant Brick
- Good acid-resistant.
- High strength and wear resistance.
- Low water absorption and low apparent porosity.
- Good eroding proofing and impact resistance.
- High temperature resistant.
- Good thermal shock resistance.
- High mechanical strength.
