产品应用：将聚醚多元醇粗品放入中和釜，在一定温度条件下加入少量纯水，搅拌后进行中和反应，将中和液PH值控制在（6.5～7.0）指标内，然后在相同的温度下加入0.1-0.3％的多硅酸铝吸附剂，保温1.5~2h进行真空蒸馏脱水，当水份脱到规定要求时进行过滤循环，分析循环液K+（Na+）离子含量，符合要求时立即进行过滤，滤液即为澄清透明的聚醚。
Product application: the crude polyether polyol was put into the neutralization kettle, a small amount of pure water was added at a certain temperature, the neutralization reaction was carried out after stirring, the PH value of the neutralization solution was controlled within the index (6.5 - 7.0), then 0.1 - 0.3% aluminum polysilicate adsorbents were added at the same temperature, the vacuum distillation and dehydration were carried out for 1.5~2 h, and the filtration cycle was carried out when the water was removed to the prescribed requirements. The K+ (Na+) ion content of the circulating liquid is analyzed and filtered immediately when it meets the requirements. The filter solution is a clear and transparent polyether.
