摘要
以ZS 2 80 1碱性粗聚醚多元醇为原料 ,采用吸附法 ,研究了聚醚多元醇中杂质钾、钠离子的脱除精制工艺。结果表明 ,成品聚醚多元醇中的钾、钠离子总量可控制在 10× 10 - 6 以下 ,可以满足软质PU泡沫塑料的应用要求。选用的吸附剂具有价廉、夹带成品聚醚多元醇少等优点。
The process of purification of crude polyether polyols of ZS-2801 is studied by adsorption, in which potassium ions and sodium ions are removed from the polyether polyols. The results show that the content of potassium ions and sodium ions of the product is less than 10×10 -6 , and the product meets the application requirement. The advantage of self-made adsorbent is economical.
