As a representative product of new energy-saving and environmentally friendly lightweight insulation bricks, mullite insulation bricks have become one of the mainstream products of insulation bricks. Its characteristics are: can direct contact with the flame, high temperature resistance, high lightness, low thermal conductivity, and significant energy-saving effects.
A characteristics of mullite insulation bricks
1. Low thermal conductivity, with good thermal insulation effect;
2. Low thermal capacity, due to low thermal conductivity, the mullite series light-weight insulation bricks absorbs little heat, and the energy-saving effect is obvious in intermittent operation;
3. Low impurity content. It has a very low iron, alkali and other oxide metal content, therefore, it has high refractoriness. High aluminum content makes it maintain good performance in a reducing atmosphere;
4. High compressive strength in hot state;
5. Accurate appearance and size, speed up the building, reduce the amount of refractory mortar, ensure the strength and stability of the masonry, and extend the life of the lining;
6. Can be processed into special shapes. In order to reduce the number of bricks and joints.
B. Application of mullite insulation bricks:
This product is a high-grade mullite refractory brick developed by our company in recent years. It has excellent performance and can be directly used for the lining of high-temperature kilns. It has been widely used as industrial furnace lining or insulation layer in tunnel kilns, shuttle kilns, roller kilns, hot blast furnaces, Glass and petrochemical kiln equipment. It is an ideal product for longevity, energy saving and efficiency.
