The core advantage is reaching EU Class A fire rating, and it does not contain any formaldehyde and other harmful substances, meeting the environmental protection and fire safety requirements of public spaces. It uses inorganic mineral fiber raw material, which can withstand high temperature up to 1200℃, and can cope with extreme high temperature environments. After spraying, a seamless acoustic layer is formed, without splicing gaps, avoiding the acoustic reflection dead angle of traditional panels. The sound absorption coefficient reaches 0.90 (500Hz), and the optimization effect for low-frequency reverberation problems of large venues is significant. The construction is convenient, and it can be directly sprayed on any flat base material without pre-installing keels, greatly reducing construction costs and cycle.
The spray thickness can be adjusted from 20mm to 100mm according to needs, with a product density of 150±10 kg/m³. It has a fire rating of EU Class A and a water resistance of IPX5, which can cope with outdoor or humid environments. The bonding strength is ≥0.3MPa, and it can firmly adhere to a variety of base materials such as concrete, steel and gypsum board. The packaging uses 25kg barreled dry powder raw materials, and each barrel can spray about 5㎡ (50mm thickness).
It is suitable for large high-speed rail stations, convention and exhibition centers, sports venues, industrial factories, underground parking lots, airport terminals and other large space scenarios. It can effectively reduce the reverberation time in the space, optimize the acoustic environment, and at the same time have multiple properties such as fire resistance, water resistance and corrosion resistance, meeting the long-term use needs of large public spaces.
