本文介绍了针对风化花岗岩蚀变带而研制的一种高分子表面防蚀喷膜材料PPOY_(1-2)。该材料具有明显的阻滞蚀变和防止遇水膨胀掉块的效果,迅速而及时地封护了新鲜岩面,保障了围岩的稳定。
In this paper, a kind of polymer surface anti-erosion spray film material PPOY_ (1-2) developed for the weathered granite alteration zone is introduced. The material has a significant blocking alteration and prevent the effect of water swelled blocks, quickly and timely sealed fresh rock surface, to ensure the stability of the surrounding rock.
