    Performance Advantages and Features of Micro-nano Insulation Bricks

    • (a) Low thermal conductivity: With low thermal conductivity, it has a good heat insulation effect and can make the furnace wall thickness thinner under the same temperature condition, thus saving more cost.
    • (b) Low heat capacity: Due to its ultra-light bulk density and low thermal conductivity, the New High-Temperature Micro-nano Insulation Bricks accumulate less heat inside, making them more energy efficient.
    • (c) Good stability: With very low iron oxide and alkali metal content, its stability is better within the specified service temperature.
    • (d) High strength: Its strength at normal and high temperatures is higher than other products with the same bulk density at the same temperature.
    • (e) Low size tolerance: The size tolerance is within 0.05mm, and the dimensions can be customized according to customer requirements.

    High-Temperature Micro-nano Insulation Bricks Applications Advantages

    Our technical department announced some of its performance indicators: the bulk density can be ≤ 0.4 g/cm3 and thermal conductivity can be ≤ 0.11. It can work in the temperature range of 600-1400°C. Due to these advantages, the insulating bricks’ application advantages are as follows:

    1. Reduce the outer wall temperature of high-temperature industrial kiln

    The actual measured data when the wall thickness of two different materials is 300mm, the data are compared as follows:

    • With Rongsheng lightweight thermal insulation block bricks, the temperature of the outer wall is 70°C (low);
    • With ordinary lightweight heat-insulating bricks, the outside wall temperature is 83°C (high).
    • The difference of outside wall temperature: 13°C↓.

    Conclusion: Rongsheng’s High-Temperature Micro-nano Insulation Bricks reduce the outer wall temperature by 18.57%↓.

    1. Reduce the weight of the furnace body of the high-temperature industrial kiln

    The actual measured data, when the temperature of the outside wall reaches 80°C, the data are compared as follows:

    •  Using Rongsheng High-Temperature Micro-nano Insulation Bricks, only 210mm thick (thin) is needed;
    •  Using ordinary lightweight thermal insulation bricks, 330mm thick (thick) is needed.
    •  The difference of wall thickness: 120mm↓.

    Conclusion: Rongsheng light-weight thermal insulation bricks reduce the thickness of the furnace wall by 57.14%↓.

    Moreover, in the compressive strength and shrinkage of the refractory insulation materials product, our High-Temperature Micro-nano Insulation Bricks products are also very advantageous.
