摘　　要：研究了铝酸钠溶液的分子比、苛性碱浓度、表面活性剂的浓度、温度和晶种添加量等因素对铝酸钠溶液种分的附聚反应速率常数的影响。结果表明:分子比和苛性碱浓度越大,铝酸钠溶液种分反应的速度变慢,反应速率常数减小;而温度升高、表面活性剂和晶种的添加量增加有利于反应速率常数的增大。The influence of molecular ratio, caustic alkali concentration, surfactant, temperature and seed load on rate constant of agglomeration process of the seed precipitation of sodium aluminate solution was investigated. It has shown that with increasing of molecular ratio and caustic alkali concentration, reaction rate constant reduce gradually. Conversely, surfactant, the high temperature and the large seed load help to increase the reaction rate constant.
