CAS-AX 铝镁质吸声毡

让工业噪声回归安静

Restoring Quiet to Industrial Noise

CAS-AX 铝镁质吸声毡是一种高效吸声材料(复合纤维毡),采用富含优质氧化铝、氧化镁、氧化硅等环保原材料,经特殊成型工艺制备而成,能在 650℃以内长期使用。材料中的鳞片结构将噪音分散并转化为微小的振动能量,有效吸收声波机械能,消耗声波传送能量,减少噪音反射,具有优异的吸音性能、防火性能和环保性能。

产品含氟氯离子极低(≤0.0039%),对金属管道设备无腐蚀性;沸水浸煮 96 小时烘干后,其绝热吸声性能基本不变。柔韧可裁剪,压缩回弹性好(≥85%),持续振动不下坠,能与设备表面充分贴合。

CAS-AX Al-Mg sound absorbing blanket is a high-efficiency absorptive material (composite fiber felt) made from premium aluminum oxide, magnesium oxide and silicon oxide raw materials that meet environmental and health requirements. Produced through a special forming process, it maintains stable performance up to 650℃. Its flake structure disperses noise and converts it into minute vibrational energy, absorbing acoustic mechanical energy, dissipating transmitted sound energy and reducing noise reflection — delivering excellent sound absorption, fire protection and environmental performance.

Extremely low fluoride/chloride content (≤0.0039%), non-corrosive to metal piping and equipment. After 96 hours of boiling water immersion and drying, its thermal and acoustic performance remains essentially unchanged. Flexible and cuttable, with compression recovery ≥85%, no sag under continuous vibration, and full contact with equipment surfaces.
