| 摘 要： | 抗冻性反映固沙剂在低温环境下固沙的耐久性能。以新型高分子材料SH进行固沙,就其固沙后固沙体的抗冻、融特性进行了室内两种不同周期的冻、融循环试验。结果表明,冻、融循环对SH固沙性能均有劣化趋势。但冻、融速率较慢时,抗冻性较稳定。SH抗冻性优于其它同类化学固沙剂,显示其抗冻性良好。有机材料在冻、融过程中一段时间内出现强度增加的机理尚不清楚,建议进一步研究。 |

| Abstract: | The freezing-thawing resistance is an index of durability of sand-fixation agent under subzero temperature.A new polymer solidified material(named SH) may be used for sand fixation,useful in control of desert.Based on the experiments on SH-fixated sand under two different freezing and thawing cycles,the resistance of freezing-thawing is studied.The results show that freezing-thawing cycles make the durability degradation,and the freezing-thawing resistance of lesser cycle speed is better.Up to now,it hasn't been known the mechanism about strength increase of solidification by organic materials in freezing-thawing process.The deep study should be made in the future,too. |
| Keywords: | desert control chemical sand fixation polymer material experiment of freezing-thawing resistance durability |
