Silica Mullite Fire Brick for Sale
Description
Silica Mullite Brick is a kind of refractory brick made of silica sand and mullite. They are characterized by refractoriness, erosion resistance and thermal shock stability. Silica Mullite Bricks are used in refractory linings, furnaces, hot air ovens, kilns and grates to provide refractory protection and thermal performance and to ensure the normal operation and productivity of the equipment.
Features
Refractoriness
Silicon Mullite Fire Bricks have excellent refractory properties and are able to withstand thermal shock, thermal expansion and chemical attack in high temperature environments. It can operate stably for a long time under high temperature conditions, extending the service life of the equipment.
Erosion resistance
Silicon Mullite firebrick has high erosion resistance to acidic and alkaline media. It is able to resist the erosion of corrosive gases, liquids and solids, and maintains the integrity of the material and the stability of its performance.
Thermal shock stability
Silicon Mullite Refractory brick has good thermal shock stability and is able to maintain low thermal stresses under rapid temperature changes, reducing the risk of cracking and breakage.
Mechanical strength
Silicon Mullite Refractory bricks have high mechanical strength and compression resistance, and are able to withstand both mechanical and gravitational loads. It maintains its structural stability and integrity in high temperature environments.
Thermal conductivity
Silicon Mullite firebricks have good thermal conductivity and are able to conduct and disperse heat effectively. This helps maintain the thermal balance of the equipment and improves thermal efficiency and energy utilization.
Lightweight
Compared with traditional refractory brick materials, silica fume brick has lower density and lighter weight. This gives it an advantage in some occasions where the weight of the equipment is required to be high, reducing the load on the equipment.
Environmentally friendly
Silicon Mullite Brick does not contain harmful substances and meets environmental standards. It does not emit harmful gases at high temperatures, making it friendly to the environment and human health.
Application
