Specifications
Acid-proof bricks use the high-quality high silicon anti-acid material, can effectively resist high sulfur smoke corrosion.
Widely used in electric power, petrochemical, metallurgical and other thermal technology equipment, chimney, pipe of easy corrosion lining, has the good use effect and service life.
Features:
1. Extruded clay products, low water absorption rate, high bending strength, anti-freeze-thaw, and highly durable.
2. Natural clay products, non-radioactive and environmentally friendly.
3. Good quality products used by our clients from around the world.
4. Can be used in various kinds of industrial stoves and thermal equipments.
5. Maintain a balanced temperature to reduce heat loss.
Advantage:
Have good thermal shock resistance and its fluctuation range is generally more than 10 times (1100 in cold water)
It has definite erosion resistance to acid slag but weak resistance to alkaline slag. Therefore is suitable for the lining of the furnace with acid slag.
Uniformity of structure, closed porosity, and good insulation properties, low thermal conductivity, high strength and fireproofing, waterproof and sound insulation, save energy
Size: All kinds of size according to our customers' requests
Color: Tawny, red, yellow, black, grey
