MANUFACTURING METHOD OF ABSORBING PANEL FOR USING GRAVEL

摘要

The method for manufacturing of sound insulating plates using gravel is characterized by forming voids between gravel and an adhesive. The voids are formed by mixing gravel having 2.0-7.0 mm diameter by crushing and an adhesive made of epoxy in order to have viscocity of about 7000 cps and weight ratio of 10:1 for gravel and the adhesive.
