广州空压机匠心厂

（1）隔声量大：平均隔声量应不小于35dB；吸声系数高：平均吸声系数应不小于0.84；

(1) large amount of sound insulation: the average sound insulation should be no less than 35dB; the sound absorption coefficient is high: the average sound absorption coefficient should be no less than 0.84;

（2）耐侯耐久性：产品应具有耐水性、耐热性、抗紫外线、不会因雨水温度变化引起降低性能或品质异常。产品采用铝合金卷板、镀锌卷板、玻璃棉、H钢立柱表面镀锌外理防腐年限在15年以上。美观：可选择多种色彩和造型进行组合，与周围环境协调，形成亮丽风景线。

(2) weather resistance durability: products should have water resistance, heat resistance, UV resistance, not due to changes in rainwater temperature, performance or quality abnormalities. Products using aluminum alloy plate, galvanized coil, glass wool and H steel column surface galvanized, external corrosion prevention period of more than 15 years. Beauty: can choose a variety of colors and shapes for the combination, and the surrounding environment in harmony, forming a beautiful landscape.

（3）经济：装配式施工，提高工作效率，缩短施工时间，可节省施工费及人工费。方便：与其它制品并行安装，易维修，更新方便。轻便：吸音板系列产品具有自重轻特点，可减轻高架轻轨、高架路的承重负荷，可降低结构造价。

(3) economy: assembly type construction, improve work efficiency, shorten construction time, can save construction cost and labor cost. Convenient: parallel installation with other products, easy maintenance, easy to update. Portable: sound absorption board series products have light weight, which can lighten the load-bearing load of elevated light rail and elevated road, and can reduce the structural cost.

（4）防火：采用超细玻璃棉，由于其熔点高，不可燃，完全满足环保和防火规范的要求。高强度：结合我国各地区不同的气候条件，在结构设计时充分考虚风荷载。通过生产线压制凹槽增加强度。防水、防尘：材料设计时充分考虑防水、防尘，在扬尘或淋雨环境中其吸声性能不受影响，构造中已设置排尘排水措施，避免构件内部积水。微穿孔共振空腔吸声在淋雨环境中吸声性能不受影响，针对中低频降噪特别明显。耐用：产品设计已充分地考虑了道路的风载、交通车辆的撞击安全和全气假的露天防腐。产品采用铝合金卷板、镀锌卷板、玻璃棉、H钢立柱表面镀锌处理。在质保期内不腐蚀、不变型、吸声、隔声效果不降低。

(4) fire prevention: superfine glass cotton, because of its high melting point, non flammable, fully meet the requirements of environmental protection and fire protection standards. High strength: combined with different climatic conditions in different regions of our country, we should take full account of virtual wind load during structural design. Increase the strength by pressing the groove in the production line. Waterproof and dustproof: when the material is designed, waterproof and dustproof are fully considered, and the sound absorption performance of the dust or rain is not affected. The dust removing and drainage measures have been set up in the structure to avoid water accumulation in the components. The sound absorption performance of micro perforated resonant cavity in the rain environment is not affected, especially for medium and low frequency noise reduction. Durability: product design has fully taken into account the road wind load, traffic vehicle crash safety and full air false outdoor anti-corrosion. Products using aluminum alloy plate, galvanized coil, glass wool, H steel column surface zinc treatment. In the warranty period, no corrosion, constant type, sound absorption, sound insulation effect is not reduced.
