The main component of acid resistant bricks is silica, which forms a large amount of Aluminum silicate under high temperature roasting, which is a substance with high acid resistance. Acid resistant bricks can also withstand alkaline medium with any concentration at normal temperature, except for high temperature molten alkali in that acid resistant bricks have compact structure and low water absorption rate. The content of SiO2 in acid resistant bricks is more than 70%, which are made by sintering. Acid-resistant bricks are made of best high-silicon acid-resistant materials, which can effectively resist the corrosion of high-sulfur flue gas. They are widely used in thermal equipments such as electric power, petrochemical and metallurgy. If you have any questions or problems, welcome to contact us for free price list.
Acid Resistant Bricks Composition
Acid resistant brick is mainly made of silica, which forms a large amount of mullite under high temperature roasting, it is a substance with high acid resistance. Meanwhile, acid resistant brick has the characteristics of pressure resistance, corrosion resistance, acid and alkali resistance and easy cleaning. The chemical composition of acid resistant bricks are as follows:
Chemical Composition of Acid Resistant Brick |
|
Ingredient | Content/% |
SiO2 | 60-70 |
Al2O3 | 20-30 |
FeO | 0.5-3 |
CaO | 0.3-1 |
MgO | 0.1-0.8 |
Na2O | 0.5-3 |
K2O | 1.5-2 |
Acid Resistant Bricks Properties
Acid-resistant bricks have high acid resistance, good temperature and acid resistance, low water absorption, are not easily oxidized at room temperature, and are not easily contaminated by media. What’s more, in addition to hydrofluoric acid and hot phosphoric acid, acid-resistant brick has excellent corrosion resistance to acids such as wet chlorine, salt water,hydrochloric acid, sulfuric acid, nitric acid and alkalis with any concentration at normal temperature. Therefore, It has the following advantages:
- Good Acid Resistant
- Good Thermal Shock Resistance
- High Strength and Wear Resistance
- Low Water Absorption Rate and Low Apparent Porosity
- Good Erosion Resistance and Impact Resistance
- High Temperature Resistant
- High Mechanical Strength
Acid Resistant Bricks Uses
Acid resistant bricks for sale in RS company are widely used in petroleum, chemical industry, medicine-making, food, paper-making, chemical fertilizer, agriculture, pesticide, chemical fibre, textile industry, smelting, and power-generating plants etc., and anti-corrosion inner liner of tower, pool, pot and sinks. What’s more, acid resistant bricks also plays a leading anti-corrosion role in waste water treatment and open air working grounds.
Apart from above mentioned, we all know that acid resistant brick is made of high quality high silica acid resistance material, which can effectively resist to the corrosion of high sulfur gas. So they are also widely used in electric power, petrifaction, chimneys of metallurgy and other thermal equipments, and the liners of flue and easy-corrosive liners.
