Issues to consider before using a flame retardant fire-retardant cloth:

1. According to different places, different flame-retardant fire-retardant sound-absorbing cloth materials should be used. Not all fire-retardant fire-retardant sound-absorbing cloth materials are omnipotent. According to different noise transmission routes, different flame-retardant fire-retardant sound-absorbing cloth materials should be selected.

2. Under normal circumstances, it can be used as a double-walled wall. At the same time, flame-retardant fire-retardant sound-absorbing cloth materials with different thicknesses and materials can be used, so as to avoid the occurrence of anastomotic effect, and at the same time, it can avoid the same material for a certain frequency. Appears. The middle cavity part has a good spring effect, which forms a combination of mass plus spring plus mass sound insulation. This combination will achieve the best sound insulation effect.

3, all sound insulation treatment requires sealing, no gaps, if the problem of sealing is not solved well, it is a waste of money to use the flame retardant fireproof sound-absorbing cloth material.
