I. Product features
1. Excellent high temperature performance. Mullite concrete has a fire resistance limit of 1600-1700℃ and can be used as a working lining in direct contact with flames. It is especially suitable for thermal equipment in high temperature environments. It has a stable crystalline phase structure and excellent heat resistance. It can maintain its structural integrity even under rapid cooling and rapid heating conditions, effectively extending the life of the furnace lining.
2. Lightweight structure design The gradient ratio technology of the porous mullite filler reduces the apparent density of the material by 40%-60% compared with traditional refractory materials, greatly reducing the load on the equipment. The lightweight characteristics not only reduce the load-bearing capacity requirements of the steel structure, but also completely solve the hidden danger of the traditional hanging brick structure being prone to breakage, and also improve the safety of equipment operation.
3. High-performance, energy-saving insulation material adopts a closed-cell microporous structure, with a thermal conductivity of less than 0.45W/(m·K) at room temperature, and an insulation performance of more than 30% even under high temperature conditions. The unique heat insulation effect effectively reduces the outer wall temperature of the furnace body, achieving a comprehensive energy saving of 15% to 20%, and meeting the energy-saving transformation needs of industrial furnaces.
4. Convenient structural characteristics It has the characteristics of rapid solidification and early strength, and compared with traditional materials, the maintenance cycle is shortened by 50%, and the kiln firing time is shortened by 30% to 40%. It adopts integral casting technology, which can quickly repair structures with complex special shapes, greatly shortening the construction cycle, and is especially suitable for emergency repair projects and projects with strict construction schedules.
