城市生态彩色透水砖自清洁性探索

Urban ecological color permeable brick from clean to explore

传统透水砖由于自清洁性能差,表面及空隙中容易被污泥或其他有机物堵塞,造成雨水渗透受阻、表面积水现象,使透水砖的使用年限缩短。这种生态自清洁透水砖克服了传统透水砖的不足,采用纳米TiO_(2)负载到面层空隙中,使其具有光催化降解污泥或其他有机物的功能;同时,通过试验得出成型压力的最佳值。

Because of the poor self-cleaning performance of traditional permeable brick,the surface and the gap are easy to be blocked by sludge or other organic matter,resulting in rainwater infiltration blocked,surface water phenomenon,so that the use life of permeable brick is shortened.This ecological self-cleaning permeable brick overcomes the deficiency of traditional permeable brick.Nano TiO_(2) is used to support the interstice of surface layer,so that it has the function of photocatalytic degradation of sludge or other organic matter.At the same time,the best value of forming pressure is obtained through the test.
