A New Type of Sound Absorbing and Isolation Material - Microck Sound Insulation Board

Microporous sand panel, as a new kind of acoustic structure that integrates good sound-absorbing performance and high sound insulation properties, is discussed in this paper. The advanced production technology using sand as raw material and silicon-based polymerization to put it together is introduced in the paper. There are a large number of connected irregular micro-pores inside the board. The porosity can be achieved by choosing different sand particle sizes to realize due sound absorption properties. Theoretical principles and technical characteristics of microporous sound panel are discussed in detail. The relevant products applied in the fields of transportation, industry and civil construction are introduced.
