1. What are thermal insulation bricks and refractory bricks?
The main function of thermal insulation bricks is to keep warm and reduce heat loss. Thermal insulation bricks generally do not directly contact the flame, while refractory bricks generally directly contact the flame.
Refractory bricks are mainly used to withstand the roasting of flames, and are generally divided into two types, namely unshaped refractories and shaped refractories. Unshaped refractories, also called castables, are mixed powdery particles composed of various aggregates or aggregates and one or more binders. They must be mixed with one or more liquids and stirred evenly when used. Has strong liquidity. Shaped refractory materials, generally made of refractory bricks, have standard rules for their shapes, and can also be temporarily processed when building and cutting as needed.
2. What is the main difference between insulation bricks and refractory bricks?
Refractory brick: 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 ℃. It is especially suitable for high and low temperature shift furnaces, reformers, hydroconverters, desulfurization tanks and methanation furnaces in chemical fertilizer plants, and plays the role of dispersing gas and liquid, and supporting, covering and protecting catalysts. It can also be used in hot blast furnaces and heating conversion equipment in the steel industry.
Thermal insulation brick: a new type of building energy-saving thermal insulation technology with inorganic composite materials as the main raw material, it is an ideal technology to replace the traditional external thermal insulation of walls. The thermal insulation brick integrates the excellent thermal insulation effect into the wall while building the wall.
Refractory bricks are very different from thermal insulation bricks, and their use environment, scope and function are different. Different materials will be used in different locations. When purchasing materials, it is recommended to determine suitable refractory materials according to the actual situation of the enterprise itself.
