What is the difference between insulation brick and refractory brick?
What is the difference between insulation brick and refractory brick? The main function of insulation bricks is to keep heat and reduce heat loss. Insulation bricks are generally not in direct contact with the flame, and refractory bricks are in direct contact with the flame. High temperature bricks are mainly used for flame burning. It is usually divided into two types: amorphous refractories and shaped refractories. Amorphous refractory materials, also called castables, refer to mixed particles composed of various aggregates or aggregates and one or more binders, which must be uniformly mixed with one or more liquids with strong fluidity. Fixed refractory materials: ordinary refractory bricks have standard shape rules and can be temporarily cut as needed. The main differences between insulation bricks and refractory bricks are as follows: 1. Thermal insulation performance. The thermal conductivity is generally between 0.2-0.4 (average temperature 350±25°C), and the ...
