AI Technical Summary
The existing fiberglass bags lack sound insulation during use, and their strength is reduced, and they are easily penetrated by external forces, resulting in the insulation board losing its protective effect.
A glass fiber bag is designed with a vacuum insulation board. The bag body is made of aluminum foil glass fiber cloth, including the first abrasive layer, aluminum foil layer, sound insulation layer, glass fiber layer, reinforced layer and secondary wear layer. The sound insulation layer is buffered and absorbed by the honeycomb layer, sound -absorbing cotton and sound insulation felt, which increases the sound insulation effect; the enhanced layer uses carbon -based composite materials to increase the strength; the buffer layer enhances the pressure resistance.
The sound insulation effect is improved by the setting of the sound insulation layer. The setting of the strengthening layer and the buffer layer improves the intensity and compressive strength to prevent the bag from being damaged by the external force and ensure the protection of the thermal insulation board.
