pc板是声屏障工程中常用的透明隔音板。在声屏障工程中，特别是城市高架桥声屏障工程中，不仅要求隔音板的隔音效果要好，同时还追求景观效果及视觉的通透性（PC mso-hansi-font-family:"Times New Roman"">耐力板的透明度好），而且也要考量高架桥的承受力（要求声屏障容重越低越好，这时PC mso-hansi-font-family:"Times New Roman"">耐力板自然是透明隔音板优先的选择）与屏障的安全性（玻璃材质的透明隔音板被肇事车辆撞击后容易破碎，重而锋利玻璃碎片从高架桥掉落，将对桥下的行人产生巨大的安全威胁，如果选用质轻的PC mso-hansi-font-family:"Times New Roman"">耐力板则安全系数大为提升）。
mso-hansi-font-family:"Times New Roman"">透明pc "Times New Roman"">板声屏障的特点：
mso-hansi-font-family:"Times New Roman"">（1 "Times New Roman"">）透光性：透明PC "Times New Roman"">板透光率可达90 "Times New Roman"">％,可与玻璃( mso-hansi-font-family:"Times New Roman"">透光性92%-95%) "Times New Roman"">相妣美。UV涂层板在太阳光下爆晒不会产生黄变，雾化，透光不佳，十年后透光流失仅为6% mso-hansi-font-family:"Times New Roman"">，PVC "Times New Roman"">流失率则高达15% "Times New Roman"">—20%，玻璃纤维为12%-20%。
mso-hansi-font-family:"Times New Roman"">（2 "Times New Roman"">）抗撞击：撞击强度是普通玻璃的250-300 "Times New Roman"">倍，同等厚度亚克力板的30 "Times New Roman"">倍，用3kg锤以下两米坠下也无裂痕, mso-hansi-font-family:"Times New Roman"">有“不碎玻璃”和“响钢”的美称。
mso-hansi-font-family:"Times New Roman"">（3 "Times New Roman"">）防紫外线：PC "Times New Roman"">板一面镀有抗紫外线（UV "Times New Roman"">）涂层，另一面具有抗冷凝处理，集抗紫外线、隔热防滴露功能于一身。可阻挡紫外线穿过，及适合保护贵重艺术品及展品，使其不受紫外线破坏, mso-hansi-font-family:"Times New Roman"">防紫外线（UV "Times New Roman"">）保护膜 太阳辐射对聚合物材料有明确害处，会使表面产生细纹引起降解。
mso-hansi-font-family:"Times New Roman"">组合透明声屏障是专门用于道路、高架、高速公路、轨道交通、铁路、住宅小区等需要隔音的板材。
mso-hansi-font-family:"Times New Roman"">组合透明声屏障有更好的隔音效果，耐老化和抗冲击能力，具有更好的安全性能，可有效地防止汽车和其它因素撞击而产生屏障脱落引起以外事故。
