Performance characteristics of A class fireproof ceramic aluminum sound-absorbing board
Fire rating:
Green environmental protection:
Sound absorption performance:
Anti-static:
Moisture resistance:
High strength and impact resistance:
The product is A1 grade non-combustible material, can withstand high temperature of 1200℃, fire resistance limit of 3 hours;
The base material does not contain asbestos, has no side effects on the environment, does not contain toxic and heavy metals, is not radioactive, will not release any harmful substances
Into the air, into the water. In case of high temperature or open flame will not produce harmful gases and smoke, in line with European E1 standards;
According to the acoustic principle combined with the multi-microporous structure system, it has excellent noise reduction and sound absorption performance, especially for medium and high frequency sound absorption effect;
Noise reduction coefficient NRC up to 0.95, in line with the level requirements;
The volume resistance is 1X106~1X108Ω electrical discharge phenomenon, which is a permanent anti-static material and can be reduced
Less dust adsorption, reduce maintenance costs;
The core is made of inorganic material containing rare earth, which has good water resistance, and its strength will not decrease under wet condition, nor will it be corroded or produce mold;
The bending strength of 5mm thickness is above 30MPA, the surface layer is dense and not easy to break, the impact resistance is strong, and it is not easy to produce
Scratch.
