AI Technical Summary
Existing flame-retardant panels cannot simultaneously meet the requirements of sound insulation and flame retardancy, resulting in the need for additional sound insulation panels to be installed in the workshop, which takes up space.
A honeycomb structure sound insulation layer is set in the flame retardant board. The porous structure of the honeycomb sound-absorbing board absorbs and dissipates sound energy. The structural strength is improved by reinforcing metal wires and locking bolts. The flame retardant effect is enhanced by combining the flame retardant compression plate and coating.
This technology enables flame-retardant panels to simultaneously provide sound insulation and flame retardancy without increasing space usage, thereby improving the efficiency of workshop utilization.
