摘要
以水溶液聚合的方式研制出了PAMN保水剂,并研究了中和度、温度、压力、pH值对其吸水性能、保水性能的影响,从理论上初步解释了PAMN保水剂的吸水、保水机理.实验结果表明:PAMN保水剂的吸水倍比达1200倍以上,PAMN保水剂具有很强的保水能力,在常温相同条件下其蒸发量为普通水的1/8～1/6.
Research into the effects of neutralization degree, temperature, pressure and pH value on the PAMN agent's ability of absorbing and conserving water has been conducted, and the principles of absorbing and conserving water of PAMN agent are revealed. One volume of PAMN agent can increase water absorbing ability by 1200 times of the PAMN volume. Under normal temperature the PAMN agent has a strong water-conserving ability and the evaporation rate of water with PAMN agent is 1/8 to 1/6 of that of normal water.
