摘要
以自制的丙烯酰胺改性羟丙基纤维素钠为固沙剂,考察其用于固沙时的固沙效果、保水性能、耐水洗性能和耐温差性能,并研究其对环境的影响。结果显示:该种固沙剂具有良好的固沙保水和耐水性能。该保水剂的保水效率增加,保水时间延长2.5倍,重复利用时,恢复固沙性能所需要的时间缩短,耐水性增加50%,且对环境的污染小。
The self-made acrylamide modified sodium hydroxypropyl cellulose was used as a sand-fixing agent to investigate the sand-fixing effect,water retention performance,water-washing resistance and temperature resistance of sand-fixing,and to study its environmental impact.The results show that the sand-fixing agent has good sand retention and water resistance.The water retention efficiency of the water retaining agent is increased,and the water retention time is extended by 2.5 times.When recycled,the time required for restoring the sand fixing performance is shortened,the water resistance is increased by 50%,and the environmental pollution is small.
