Open Cell Aluminum Foam Board for Construction

Introduction

  As for spherical aluminum foam, its bubble chamber is spherical and relatively regular. The bulkhead is provided with small round holes to connect with the sphere, and the holes are divided into six directions to avoid straight through holes, which is conducive to sound absorption, filtering and noise elimination. In practical application, the ideal application effect can be obtained by designing and controlling the ball size (diameter 4-13mm), wall hole size (diameter 0.5-4mm), hole wall thickness and plate thickness. Bulk density: 0.5-0.8g/cm3. The national building materials testing center of the Ministry of construction has identified that the noise reduction coefficient of spherical aluminum foam exceeds international standards. The spherical foamed aluminum products produced by our company is a kind of material that combines the advantages of open holes and closed holes to overcome the shortcomings of open holes and closed holes.
  Spherical foam aluminum is an excellent product of foam aluminum acoustic material at home and abroad. It is suitable for noise elimination and noise reduction of various vehicle boxes and mechanical equipment. Due to the uniform distribution of spheres, the same hole shape and regular hole wall, the specific absorption energy is longer. It has excellent impact resistance. Compared with the irregular pores of closed cell aluminum foam, the open hole wall of the sphere is not liable to fracture when subjected to impact. It is used as shock resistant buffer material and has better performance.
