- After repeated comparisons and experiments, scientists have at last chosen the high-modulus potassium silicate, or PS, as the ideal sand fixing agent. 经过反复比较实验，科学家们终于选定了高模数硅酸钾，即ps，为最理想的固沙剂。
- Therefore, not only should the sand fixing cementing agent reach due strength, but also it has to be highly effective in enabling water to seep and be absorbed. 因此，固沙胶结剂不但要达到应有强度，还必须满足良好的渗水、吸水性要求。
