| 摘要: |
| 以有机高分子吸水树脂对水分子的强吸附能力为启示，以改性聚丙烯酸钠吸水树脂为基础，研究了该树脂与LiCl共混物在不同相对湿度条件下的吸湿性能，分析了该共混物对密闭容器相对湿度的影响。在此基础上，提出了对该共混物的平衡吸湿量及密闭空间内吸湿平衡点进行理论预测的方法。利用该方法，通过调整吸湿材料的用量，可将空间湿度控制在实际需要的范围。 |

| Abstract: |
| The moisture absorption property of the mixture of modified sodium polyacrylate and LiCl under different relative humidity was studied. The influence of the mixture to relative humidity of the environment was analyzed. The theoretical method of predicting environmental relative humidity at the balance state was proposed. The environmental relative humidity can be controlled at certain range by adjusting the dosage by this method. |
