  • Thermal insulation brick is the main role in our lives is used to heat preservation and reduce heat loss, thermal insulation brick will not generally be directly in contact with the flame, and firebrick is directly in contact with the flame, firebrick is used to withstand the flame baking, then what is the difference between lightweight thermal insulation brick and firebrick?

    1. thermal insulation performance

    The thermal conductivity of thermal insulation brick is generally 0.2-0.4 (average temperature 350 65

    2. refractoriness

    The refractories of insulation bricks are generally below 1400 degrees, while refractory bricks are more than 1400 degrees.

    3. density

    Insulation bricks are generally lightweight insulation materials, density is generally 0.8-1.0 g/cm 3 and refractory bricks are basically more than 2.0 g/cm 3 density.

    In summary, we summarize as follows: refractory bricks have high mechanical strength, long service life, good chemical stability, no chemical reactions with materials and good high temperature resistance, heat resistance temperature can reach 1900%. Especially suitable for high and low temperature shift furnace, converter, hydrogenation converter, desulfurization tank and methanation furnace in chemical fertilizer plant, play a role of dispersing gas and liquid, supporting, covering and protecting catalyst. It can also be used in hot blast stove and heating conversion equipment in iron and steel industry.
