Ceramic Sound Absorbing Material
Ceramic Sound Absorbing Material INHALE carries out press molding of what mixed inorganic hard particle, inorganic glaze, etc. And calcinates at the high temperature of 1000°C or more.
By calcinating, INHALE joins together so that hard particle may be connected with a point with glaze, and narrow space is formed between hard particles. The energy of sound collides with hard particle because sound passes through this space, and sound is changed into thermal energy.
Compared with the glass wool and rock wool which are generally used as sound absorbing material. INHALE is strong by water, fire, humidity, and chemically stable. And Environmental hormones is not contained.
INHALE is most excellent design for sound absorbing material.
