吸水性树脂吸水性及保水性的研究

STUDY ON THE CAPACITIES OF ABSORBING AND RETAINING WATER OF THE ABSORBENT RESIN

研究了吸水性树脂ＢＨＨ－Ａ在不同条件下的吸水性能和保水性能。在电解质水溶液中吸水能力下降；在非电解质水溶液中吸水能力不受影响；ｐＨ值在４～１０水溶液中吸水能力不受影响。在室温及６０℃环境中，所吸收水的蒸发、扩散是极其缓慢的。

The absorbent resin BHH A, which was synthesized by means of suspension polymerization, was studied on the capacities of absorbing water and retaining water under different condition. The capacities of absorbing water is declining in electrolytic solution, which is not affected by non electrolytic solutin and pH value 4￣10 solution. Absorbing water is evaporating and diffusing extremely slowly under 20 ℃ and 60 ℃.
