中文摘要:研究了淀粉基多孔高吸水树脂的合成及其吸液性质,比较了不同致孔剂如丙酮、碳酸氢钠、蔗糖对树脂吸液速率的影响。结果表明,添加致孔剂能有效提高树脂的吸液速率,碳酸氢钠具有较好的致孔效果。扫描电镜分析证明,合成的高吸水树脂具有疏松的多孔结构,它是提高高吸水树脂吸液速率的主要原因。

Abstract:In this paper, the synthesis of porous superabsorbent was performed using sodium bicarbonate, acetone, and sucrose as porosity generators. Compared to the superabsorbent prepared under porous-free condition, the results showed that porosity generators can improve absorbency rate effectively, and that sodium bicarbonate has a better effect than others. Morphological studies with scanning electron microscope (SEM) showed that the superabsorbent has the loose and porous structure. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
