摘要
用周期浸泡加速腐蚀试验法研究pH为1.0、3.5、5.6等3种模拟酸雨条件对大理石、花岗岩和马赛克的影响,通过观察材料的外观、质量和体积的变化,来评定材料的腐蚀程度,从周浸后酸雨化学组分的变化得到酸雨对材料的溶解速率。研究得到各材料对酸雨的抗侵蚀能力为:陶瓷、玻璃马赛克>花岗岩>水泥马赛克>大理石。
Effects of simulated acid rain under pH value of 5.6, 3.5 and 1.0 respectively on marble, granite and mosaic by using periodical immersion corrosion accelerating method have been conducted. The corrosion degree of samples were then evaluated in accordance with their changes in appearance, weight and volume. In addition, the dissolved rate of the building materials in acid rain could be obtained by analysis of the change of chemical components after immersion. It was concluded that corrosion-resistant capacity varied with the different material and might be summed up as the following order: ceramic or glass mosaic > granite > cement mosaic > marble.
