| 中文摘要: |
| 介绍了制浆废液木质素的结构特征、不同改性方法制备的木质素类固沙剂的结构与固沙效果,并提出了木质素类固沙剂的改性研究思路。制浆废液中木质素来源丰富、价格低廉,改性后可提高沙子或土壤的抗压强度、抗风蚀强度、聚集体的含量等,因而在防风固沙方面逐渐成为研究热点。 |
| Abstract: |
| Lignin from pulping waste liquor has attracted more and more attention recently because of its abundance and low cost. It can be modified and used as sand-fixing agent to improve some properties of sand or soil, such as the compressive strength, the ability of resistant to wind erosion, aggregate content. In this paper, the characteristic chemical structures of lignin, structure and sand-fixing efficiency of several modified lignin sand-fixing agent were reviewed. Finally, some modified methods were suggested and these suggestions would be useful for developing effective lignin sand-fixing agent and fully utilizing the lignin from pulping waste liquor. |
