摘要
对淀粉—丙烯酸钠合成的吸水树脂工艺,及其吸湿放湿性、吸水保水性、抗蒸发性等抑制路(地)面扬尘的性能进行研究。结果表明:此吸水树脂的合成工艺简单,抑尘性能较好;用它喷洒高扬尘路(地)面,能保持有利于抑尘的含水量,增强路(地)面的稳定性,因此可有效抑制粉尘飞扬,且有效抑尘时间较长。
Description of preparation of a water absorbent resin of graft sodium salt of acrylic acid onto starch, and its characteristics of moisture absorbing and releasing behaviour etc. were presented. The results showed as follows: 1) the water absorbent resin could be prepared by means of simple process; 2) spraying with the resin gel, dirt or dust on the road could be kept in good dampness, and fly ash could be controlled effectively, and effective time was longer.
