Sound insulation, heat insulation, heat preservation: the honeycomb itself doesn’t possess the capability of sound insulation and heat insulation, but the structure of honeycomb sandwich possesses very good capability of sound insulation and heat insulation. In the common used aluminum honeycomb core of the honeycomb sandwich, the volume of entity material is only 1%～3% of the total. Within the other space, there is the air that is closed in. The honeycomb sandwich is of very good heat insulation and sound insulation capability because of the air’s performance of sound insulation and heat insulation is better than any solid materials and limits the heat energy and sound wave greatly.

Fireproofing: after testing and authenticating by the National Center for Quality Supervision and Testing of Fireproofing Building Materials, various performance indexes of the materials are all conformed to the regulations and requirements of flame-resisting material. The flame-resisting feature of the materials is up to level GB-8624-A according to the national standard GB-8624-1997

Excellent flatness and rigidity: because the honeycomb core is under stress vertically, every board is with incalculable fixed honeycombs and will not produce moving, so the board will be very stable and keep its form unchangeable even if striking by outside force (such as typhoon etc.). Aluminum honeycomb sandwich composed of many dense honeycombs pinning against each other is just like many small I shape girders that can bear the pressure separately from the direction of face sheet. This makes the board being pressed evenly, ensures its intensity of pressure bearing and keeps high flatness when the face sheet is with larger area.

Light material and energy saving: the weight of aluminum honeycomb sandwich-core is only 1/5 as aluminum plate and 1/10 as steel plate but it’s with the same rigidity. The weight of per square meter aluminum honeycomb sandwich, with total thickness 15mm, face sheet of aluminum 1.0mm and bottom sheet of aluminum 0.8mm, is only 6kg. The weight of per square meter aluminum honeycomb sandwich, with total thickness 10mm, face sheet of aluminum 0.5mm and bottom sheet of aluminum 0.5mm, is only 4 kg. Comparing with the weight of traditional aluminum-plastic board, the weight of per square meter is less about 2 kg. But its rigidity is more than 2 times stronger than the rigidity of aluminum-plastic board. It can compare beauty with aluminum board of 4mm thickness. Its price/performance ratio is evidently high than the price/performance ratio of aluminum-plastic board and aluminum board. So the materials can be saved effectively.

Environment protection: the material will not emit any gas material that is harmful to human health. Easy to clean and can be recycled.

Moisture-proof: the material will not absorb water. Its surface is applied filming technology. It will not change color for long. In the damp environment, the material will not be mildewed or distorted.

Antisepsis: after testing, the material dipped in 2%HCL solution for 24 hours without any change. The material dipped in Ca (OH) 2 saturated solution for 24 hours without any change.。

Construction convenience: with the aluminum alloy keel, the installation will be convenient, fast, both saving time and labor; it can be installed, dismantled and transferred repeatedly.

Excellent shock-absorption performance: because of many dense honeycombs pinning against each other is just like many small I shape girders that can bear the pressure separately from various directions, so it’s with stronger antiseismic ability.
