About the characteristics and differences of firebrick and insulating brick

Date of release:2019-04-19 Author: Click:

Appearance of the same two types of brick, from various aspects to compare what are the different insulation brick and refractory, refractory to play "mediation" in general, the insulating brick as wall and some building materials is more appropriate, the following is the comparison of the various aspects of the data, as follows: the following about "about the characteristics of refractory and thermal insulation brick and different" is introduced.



 



 

[what are the advantages of firebrick and insulation brick compared to each other?]


Fire resistance


The fire resistance of the insulation brick is generally below 1400 degrees, and the fire resistance of the firebrick is above 1400 degrees.


Ii. Thermal insulation performance


The coefficient of thermal conductivity of insulating brick is in commonly 0.2 0.4 (uniform temperature to 350 + 25 ℃) w/m.k, and the coefficient of thermal conductivity of refractory brick (uniform temperature to 350 + 25 ℃) in 1.0 w/m.k above, which can be concluded that thermal insulation brick heat preservation function than refractory insulation function better.


Three, density


Thermal insulation brick is generally light thermal insulation material, the density is generally in 0.8-1.0g/cm3, and the density of firebrick is basically in 2.0g/cm3 above.


What are the advantages of insulation bricks and refractory bricks


Insulating brick


Thermal insulation brick is a kind of new building energy conservation thermal insulation technology with inorganic composite material as the main raw material. When laying the wall, the thermal insulation brick integrates the excellent thermal insulation effect into the wall.


Refractory brick


It is especially used in high and low temperature converter, reformer, hydrogenation converter, desulfurization tank and methanation furnace for dispersing gas and liquid, supporting, covering and protecting catalyst.


It can also be used in hot blast furnaces and heat conversion equipment of iron and steel industry.


Firebrick of high mechanical strength, use cycle is long, and the chemical is not good, does not react with the material and the good function of high temperature resistant, heat resistant temperature can reach 1900 ℃.



[what is the difference between the characteristics of thermal insulation brick and firebrick?]


From our fire brick and insulation brick characteristics, we will certainly feel that the fire brick is aimed at refractory, and the insulation brick is more focused on insulation performance. More specifically, we still learn from the following parameters.


Choice on the thermal insulation performance, the coefficient of thermal conductivity of insulating brick insulation brick is in commonly 0.2 0.4 (the average temperature of 350 + 25 ℃) w/m.k, and the coefficient of thermal conductivity of refractory brick (average temperature of 350 + 25 ℃) in 1.0 w/m.k above, which can be concluded that thermal insulation brick insulation heat preservation performance is much better than brick.


And the fireproof degree on fireproof degree the fireproof degree of heat preservation brick is in commonly 1400 degrees the following, and the fireproof degree of fireproof brick is in 1400 degrees above. In terms of density, thermal insulation bricks are generally light thermal insulation materials, with a density of 0.8-1.0g/cm3, while the density of refractory bricks is basically above 2.0g/cm3.


The main function of insulating bricks is to keep warm and reduce the loss of heat. Insulation bricks generally do not have direct contact with the flame, while refractory bricks generally have direct contact with the flame. Both firebricks and insulation bricks have their own advantages. Different materials are used in different positions.


The above introduction of "what are the advantages of firebrick and insulation brick compared with each other" and "what is the difference between the characteristics of firebrick and insulation brick?" I hope it can help you understand "the characteristics and difference between firebrick and insulation brick".
