Research on Aluminum Alloy Foam Sound Insulation Characteristics of New Decorative Building Materials Ying Yang North China Institute of Science and Technology, Beijing, China Keywords: building materials; aluminum alloy foam; sound insulation characteristics; sound insulation coefficient.
Research on its sound insulation performance has also become a hot topic of materials science and other fields.
According to soundproof mechanism of building materials, construction materials can be divided into three categories [7]: porous soundproof material, the resonance sound insulation materials and other soundproofing materials.

Introduction High-water material is a kind of high water content and rapid solidification gelling materials.
So the specimen was in contact with water, and in this way, the real stress condition of engineering materials under pressure water can be factually simulated.

With the continuous development of Chinese science and technology, structured ultra-light porous metal materials are a new type of multifunctional materials that have emerged with the increasing demand for diverse materials preparation and machining technologies in recent years.
Porous metal materials are materials that are good for the environment.
In addition, with the rapid development of science and technology, we have more scientific and technological means, and thus have greater ability to develop and research new materials.

The problem following is that process brings too much unrecycle talc paper plate leftover materials when the talc paper plate is cut out and molding.
Those leftover materials always be abandoned as crab.
Different concentrations of immersion materials indicate the same variation rule.
Influence of immersion concentration Figure2 indicates that decomposition rate increases as concentration of immersion materials increases, but the variation amplitude is less.
