农林用高吸水材料的凝胶强度与吸水倍率关系

Relation between Gel Strength or Super-absorbent Polymer for Agriculture and Forestry and its Water Absorbency

以工业废胶为原料，在不同交联和水解工艺条件下制备出交联的聚丙烯酸盐类高吸水材料，测定结果表明：高吸水材料的凝胶强度与吸水倍率成反比关系。

With industrial waste as raw materials, a series of super-absorbers of polyacrylic acid salt are prepared at different crosslinking and alkali hydrolytic conditions including concentration, time and temperature. By measuring the water absorption and deformation of gels under the certain strain, the curves of deformation and water absorbency are provided, revealing the inverse ratio between gel strength and water absorbency.
