Main Difference between Insulation Bricks and Refractory Bricks
The main difference between insulation bricks and refractory bricks. Insulation bricks and refractory bricks are refractory materials and insulation materials commonly used in furnaces and various high-temperature equipment. Although they are all brick refractory materials, their performance and use are completely different. Today I will introduce the main functions and differences between the two.
Insulation bricks are mainly used to keep heat and reduce heat loss. Generally, insulation bricks do not directly contact the flame. Refractory bricks can generally directly contact the flame or hot solution, and can withstand the flame of the flame, the erosion and abrasion of the solution.
The main differences between insulation bricks and refractory bricks are as follows:
1. Thermal insulation performance: The thermal conductivity of thermal insulation bricks is generally 0.2-0.4 (average temperature 350 ± 25 ° C) w / mk, while the thermal conductivity of refractory bricks is above 1.0 (average temperature 350 ± 25 ° C) w / mk. It can be concluded that the thermal insulation performance of thermal insulation bricks is much better than that of refractory bricks.
2. Fire resistance: The fire resistance of insulation bricks is generally below 1400 degrees, while the fire resistance of refractory bricks is above 1400 degrees.
3. Density: Insulation bricks are generally lightweight insulation materials, the density is generally 0.8-1.0g / cm3 and the density of refractory bricks is basically above 2.0g / cm3.
Refractory Bricks Characteristics
In general, refractory bricks have high mechanical strength, long service life, good chemical stability, no chemical reaction with materials and good high temperature resistance. The maximum heat resistance temperature can reach 1900 ° C. It is especially suitable for high and low temperature conversion furnaces, conversion furnaces, hydrogenation converters, desulfurization tanks and methanation furnaces in fertilizer plants. It plays the role of dispersing gas and liquid and supporting, covering and protecting catalysts. It can also be used in hot blast stoves and heating conversion equipment in the steel industry.
Refractory bricks have the advantages of high density, high strength, wear resistance, good corrosion resistance, small thermal expansion coefficient, high grinding efficiency, low noise, long service life, and no contamination of materials. It is a high-quality grinding medium suitable for various grinding machines.
How to Choose Furnace Bricks?
Refractory bricks are very different from thermal insulation bricks, and their use environment, scope and function are different. RS Cheap Refractory Bricks Manufacturer notes that, Different materials will be used in different locations. When choosing materials, we must decide which refractory material is suitable for our own use according to our actual situation.
