| 中文摘要: |
| 以丙烯酸和凹凸棒粘土为原料合成了有机-无机复合保水剂,模拟实际应用情况对其吸水、释水及耐盐性能与德国BASF的M7055型保水剂进行了对比研究。结果表明:加入凹凸棒土合成的PAA-atta型保水剂具有更高的吸水倍数和耐盐碱性能,综合性能优于M7055型保水剂。 |
| 英文摘要: |
| The polyacrylic/attapulgite (PAA-atta) superabsorbent composite was prepared by crylic acid and attapulgite clay to investigate its water retention ability and swelling behaviors in various saline solutions and fertilizer concentration, being compared with BASF M7055. The results indicated that PAA-atta composite had a higher water absorbency and salt resistance,and its general property was superior to M7055 superabsorbent. |
