Building Envelope Aerogel Coating

 

Key Properties：

1. Excellent fire performance: belongs to non-combustible materials, fire performance up to A level, has good flame retardant, will not spontaneous combustion or combustion; The nanopore structure can limit the air flow and inhibit the convection conduction, and the three-dimensional network structure can form the reflection and refraction surface of thermal radiation, which can make the protected substrate fail to reach the ignition point in the case of fire.

 

2. Strong weather resistance: the overall hydrophobic, hydrophobic rate of up to 99% and above, not easy to absorb water disintegration, can maintain stable insulation performance in complex natural environment, effectively prevent wall water seepage and mold; It has good anti-aging performance, is not easy to crack, fall off, insulation effect decay and other problems, and its service life can reach more than 10-15 years.

 

3. Convenient construction: spraying, brushing, scraping and other construction methods can be used to adapt to different building structures and surface forms, without complex fixing and splicing processes, and can quickly form a uniform and continuous insulation layer, shorten the construction period and improve construction efficiency.

1. Industrial plant: can be applied to the roof and wall of the plant, resist the harsh external environment, keep the internal temperature of the plant stable, create good working conditions for production equipment and workers, and help save energy consumption in industrial production.

2. Commercial buildings: such as shopping malls, office buildings, hotels and other large commercial buildings, the use of the coating can reduce energy consumption costs, while improving the quality of the indoor environment, providing customers and staff with comfortable space. For example, the large area of the glass curtain wall of the shopping mall uses an aerogel coating, which can reduce the entry of solar radiant heat and reduce the indoor air conditioning load.

3. Residential: can be coated on the exterior wall, roof, ground, doors and Windows of the residential area, effectively block the outdoor heat into the indoor, reduce the energy consumption of summer air conditioning refrigeration and winter heating, and improve living comfort; It can also prevent dew, mold and other problems caused by cold and hot temperature difference on the wall, and extend the service life of the building.

1. Can the coating be used with other insulation materials?
Yes, the coating can be used with other thermal insulation materials such as rock wool, polystyrene board, etc., which can play a synergistic effect of thermal insulation and further improve the thermal insulation performance of the building. For example, in some buildings with high insulation requirements, the rock wool board is installed first, and then the surface is coated with a coating.

2. What is the bonding effect between the coating and different building wall materials?
The coating has good bonding properties with common building wall materials such as concrete, bricks, aerated blocks, etc. However, before construction, it is necessary to ensure that the surface of the wall is clean, smooth and dry to ensure that the coating can be firmly attached to the wall.

3. How strong is it? Is it easily scratched or damaged?
The coating has a certain strength and wear resistance, but compared with some hard building materials, its surface hardness is relatively low, and damage may occur when it is vigorously scratched or collided by sharp objects. However, under normal use, as long as it is not deliberately destroyed or subjected to extreme external forces, it can generally maintain good integrity.
