Choosing a suitable insulating brick requires comprehensive consideration of its performance, application scenarios, cost and construction requirements. Here are some key suggestions and points to help you choose the most suitable insulating brick:

I. Clear application scenarios

Building thermal insulation: If it is used for building roof or wall thermal insulation, it is recommended to choose insulating brick with high solar reflectivity (SR) and infrared emissivity (E). For example, the electroless refrigeration coating of Chuangleng Technology has a SR value of 95% and an E value of 93%, which can significantly reduce the surface temperature.

Industrial high-temperature equipment: For industrial furnaces, hot stoves and other high-temperature equipment, it is necessary to choose insulating brick with high temperature resistance and low thermal conductivity, such as high-alumina insulating brick or mullite insulating brick.

Special environment: If the application environment requires high environmental protection, it is recommended to choose nano-composite thermal insulation materials, which have low carbon emission and long service life in the production process.

II. Focus on performance parameters

Thermal conductivity: The lower the thermal conductivity, the better the thermal insulation effect. For example, the thermal conductivity of ordinary insulating brick is 0.5-0.8 w/(m k), while that of new thermal insulation materials such as polyurethane foam is only 0.2-0.3 w/(m k).

Sunlight reflectivity and infrared emissivity: For building thermal insulation, the solar reflectivity should be greater than 90% and the infrared emissivity should be greater than 90%, which is the key index to achieve efficient thermal insulation.

Compressive strength and durability: Choose the appropriate compressive strength according to the usage scenario. For example, the compressive strength of ordinary insulating brick is 0.8-2.5 MPa, while the compressive strength of high-alumina insulating brick is higher.

III. Construction adaptability

Shape and size: For building surfaces with special shapes (such as domes and curved surfaces), it is recommended to choose liquid thermal insulation coating, which is more flexible in construction and can be sprayed or rolled.

Construction Difficulty: Choosing insulating brick with simple construction can reduce labor cost and construction time. For example, the self-adhesive insulating brick is designed with hexagonal bricks, which are closely attached to each other, making the construction convenient.

IV. Environmental protection and cost

Environmental protection performance: environmental protection heat insulation materials are preferred, such as nano-materials certified by EU REACH, which have low carbon emission and long service life in the production process.

Cost: Choose insulating brick with high cost performance according to the budget. For example, the price of ordinary insulating brick is relatively close to the people, while high-performance thermal insulation materials such as aerogel have good thermal insulation effect, but the cost is higher.

V. Quality inspection

Appearance inspection: The surface of high-quality insulating brick is smooth and clean, and the back should be smooth and tidy. Inferior brick has rough surface and rough back.

Water resistance: insulating brick with strong permeability resistance can be judged by observing its water resistance.

Hardness test: High-quality insulating brick is durable and can bear a certain weight, while inferior bricks are easy to break.

VI. Supplier selection

Third-party test report: Require suppliers to provide third-party test reports, focusing on thermal insulation performance, durability and environmental protection indicators.

After-sales service: Select the suppliers that provide comprehensive after-sales service, including construction guidance, quality assurance and after-sales maintenance.

Through the comprehensive consideration of the above points, you can choose the insulating brick that best suits your needs and ensure the best balance between heat insulation effect, durability and cost.
