防潮性能
Moistureproof performance
In the standard configuration of light steel housing, the periphery of the entire wall using one-way breathing paper to seal the entire wall. The seal can be cut off in the moisture enter indoor and outdoor, avoid harmful material outdoor atmospheric corrosion of metal material, also can eliminate indoor humidity. And the whole wall use plasterboard wall also be able to breathe. Breathing and moistureproof film paper can guarantee in a sealed metal products and dry space has more long life, also can make indoor air more dry.
Fireproof performance
Exposure of the light steel structure under the high temperature of 550 ℃, generally in 15 minutes or so will lose bearing capacity and collapse. Chongqing steel structure company but through paint, composite or thickening palisade materials, using some fire on palisade structure performance is good material, can ensure the whole residential fire performance to achieve the requirement of the specification.
From the perspective of the practice of the light steel structure villa, fire prevention with special light steel structure housing can meet the requirements of the code for fire protection. In the national fixed fire extinguishing systems and fire-resistant components of quality monitoring center of real tests, bluescope steel equipped with double double plasterboard wall refractory experiment, the fire resistance of bearing wallboard can reach 1.22 hours.
Sound insulation performance
Light steel structure housing the slabs due to dead weight is lighter, and basically to the hollow structure, it is easy to form the tympanic membrane effect, so the impact sound insulation effect is very poor. In order to meet the sound insulation and air impact sound insulation of the comprehensive requirements, in the light steel structure housing, can use external walls and floor joists fill glass wool, chongqing steel structure company to effectively prevent the audio part of spreads through the air. Tests show that fill the glass wool can make the structure of the air sound insulation effect is increased further, amounting to more than 50 db before palisade structure processing, will be able to meet the needs of living.
