| 摘 要： | 概述了沙土稳定高分子材料的分类及其应用；研究了禾草类木质素横酸盐及接枝产物对流动沙土的稳定作用，认为木质素磺酸盐本身不是适用的沙土稳定剂；通过对其粗产品直接进行接枝改性，产物的沙土稳定效率得以明显提高，应用试验表明，改性产物用量在10g/m^2时，沙土可以抵御风速为76km/h的侵蚀；而接枝非离子型单体可以进一步提高沙土的抗水蚀效果；最后提出了对适用的沙土稳定剂的一些要求。

| Abstract: | Polymer stabilizers can improve the structure of sandy soil,and may be used in controlling the soil desertification.The effects of non woody lignosulfonate and its grafted polymers on stabilizing sandy soil were studied.It is suggested that the lignosulfonate itself is not an applicable stabilizer,but after grafted with acrylic monomers its efficiency on sandy soil stabilization is improved.The grafted polymers are sprayed on the surface of sandy soil,with application dosage of 10?g/m 2 ,the sandy soil can withstand wind erosion with speed of 76?km/h.By polymers grafted with non ionic monomers,the sandy soil has higher resistance on water erosion.The polymer stabilizers applicable for improving sandy soil should have higher molecular weight,certain hydrophilicity and degradability,and be economical and environment friendly. |
