| 中文摘要: |
| 通过高温高压试验分析了颗粒尺寸、温度、橡胶质量分数对复合吸水膨胀橡胶颗粒在CO2中的膨胀性能。结果表明：在相同温度和压力下，复合吸水橡胶颗粒尺寸越小和橡胶质量分数越高，其在CO2中膨胀倍数越大；压力和时间相同时，温度越高，复合吸水橡胶颗粒在CO2中膨胀倍数越大。 |
| 英文摘要: |
| The effects of particle size，temperature and mass fraction of rubber on the expansion properties of composite water-absorbent swelling rubber particles in CO2 were analyzed by high temperature and high pressure experiments.The results showed that，at the same temperature and pressure，the smaller the particle size and the higher the mass fraction of the composite water-absorbent swelling rubber were，the larger the expansion ratio in CO2 was.When the pressure and time were the same，the higher the temperature was，the bigger the expansion ratio of composite water-absorbent swelling rubber particles in CO2 was. |
