The lightweight insulation bricks are made of high-density concrete data and two-layer protection structure, which is sufficient to resist the external polar climate and rainwater infiltration, meet the anti-seepage requirements of the external wall, overcome the low density of aerated concrete, high water absorption and lack of anti-seepage function. Defects, reducing the cost of protection in the later stages of construction.
1. Insulation and adiabatic function. Lightweight insulation bricks are resistant to high temperatures and can be used to reduce energy consumption.
2, fire protection. Lightweight insulation bricks can reach the national standard non-combustible grade A.
3. Clean and environmental protection functions. Light insulation bricks will not cause secondary pollution of the air.
4, light weight. Lightweight insulation bricks weigh only about 1.4 kilograms per square meter, reducing the load on the building.
5, the manufacturing technology is abbreviated. Lightweight insulation bricks completely break the traditional technology and greatly shorten the construction period.
6, beautiful: lightweight insulation bricks can be made into a variety of colors, suitable for surface mounted.
7. Durable: Lightweight insulation bricks have a long service life.
 In addition to the biggest feature of lightweight insulation bricks, the heat transfer coefficient is low (k=1.24) and thermal inertia (D=3), which is satisfactory for the planning requirements of the external wall self-insulation. Insulation is 25 times that of concrete and 20 times that of sintered bricks, which can greatly save energy consumed by air conditioning and winter insulation in summer, and reduce building emissions, in line with the national goal of 65% energy saving.
What are the precautions for lightweight insulation bricks?
1. The lightweight refractory brick has a large porosity and loose structure, and cannot be used for direct touch of molten slag and liquid metal;
2. The mechanical strength is low and cannot be used for load-bearing construction;
3, the wear resistance is very poor, it is not suitable for the parts with the touch and wear of the furnace material.
    After the above analysis, let us understand the advantages and disadvantages of lightweight insulation bricks, so that we know how to use light insulation bricks reasonably to avoid unnecessary losses, and also make rational use of energy to achieve energy saving. The effect of the row.
