water retention capacity

A Study on the Water Retention Capacity of Saps and Affecting Factors

高吸水性树脂吸水保水能力及影响因素的研究

Maximum water retention ratio and water-holding capacity of litter were 269.4%.

林地枯枝落叶层现存量平均为6.660t·hm-2，最大持水率为269.4%。

Water retention agent is a kind of man-made high-hygroscopicity resin, which has super absorbent and maintaining capacity of water.

保水剂又称吸水剂、高吸水性树脂，是人工合成的一种具有超高强吸水、保水能力的高分子聚合物。

Owing to its high capacity for absorbing water, high degree of water retention under pressure and high thickening power, it is widely applied to paper diapers, underpads, water holding agents for soil, industrial dewatering agents, thickener etc.

由于其高吸水性、在压力下的高保水性和高增稠性，被广泛应用于纸尿布、生理巾、土壤保水剂、工业脱水剂、增稠剂等。
