Compared with prior art, the utlity model has following advantage:
1. utilize the characteristics of fiberglass acid-fast alkali-proof good weatherability, make sound absorbing-insulating barrier, can round-the-clock use under various rugged environments, and fiberglass is a kind of environmental protection sound absorption and noise reduction material.
2. in the middle of perforation protection slab and sound insulation backboard, fill ultramicropore sound absorbing membrane acoustic absorbant, can increase the sound sucting band width, be not subjected to rainwater, steam, high humidity and influence the decline of sound absorbing capabilities, be applicable to purify demanding field of employment that tenure of use is long.
3. owing to can select the aluminium alloy extrusions of different colours for use, the fiberglass mask perforated plate of different colours and fiberglass backboard have reached requirement elegant in appearance.
4. utilize the good soundproof effect of fiberglass, can well guarantee the sound insulation property of sound absorbing-insulating barrier.
Fiberglass than the light 3-4 of steel doubly, and intensity is higher 1.7 times than steel, therefore the sound absorbing-insulating barrier of making has light weight, high-strength characteristics.
6. the perforation protection slab and sound insulation backboard that adopt fiberglass to make, have high temperature resistant, ageing-resistant, corrosion-resistant, not yielding, wear-resisting wiping, the beautiful characteristics such as comfortable of outward appearance.
7. adopt aluminium alloy extrusions to make sound absorbing-insulating barrier, corner adopts compact heap to be connected with screw, and the sound absorbing-insulating body structure is firmer, and it is more convenient to make production, just wants large-scale production processing.
8. perforation protection slab, sound insulation backboard and aluminium alloy extrusions housing adopt direct inserting mode, and production is installed more convenient.
9. use the waterproof sound absorbing membrane between perforation protection slab and resistive acoustic absorbant, under the prerequisite that has improved sound absorbing capabilities, the more effective assurance do not change sound absorbing capabilities in round-the-clock operating position.
10. obtain effective control in its Costco Wholesale, and do not influenced its sound absorbing capabilities and structural strength performance, demonstrated fully the superior cost performance of material.
The utility model can be used for the indoor and outdoor sound absorbing-insulating barrier, has protected people's life not to be subjected to the pollution of noise.
