应用于洗涤剂工业的高稳定过碳酸钠研究进展

Advances in studies of stable sodium percarbonate applied in detergents

介绍了国外提高过碳酸钠 (PCS)稳定性的多种方法 ,对以洗衣粉为应用目的的采用包覆法提高过碳酸钠稳定性方法进行了较详细的论述。所用包覆材料有无机盐、有机酸盐、可水溶性高聚物等。最后 ,提供了用无机盐和高分子材料相结合进行多层包覆产品 ,其溶解性适合应用 ,在 40℃、相对湿度 80 %下存放二周稳定性考察结果 (活性氧留存率 )为 :单独稳定性 90 %以上 ,加入标准洗衣粉中稳定性 80

Many kinds of methods which are used abroad in raising the stability of sodium percarbonate are introduced.The coating materials include inorganic salts,organic salts and water soluble polymers etc.,Here,the product multi-layer coated with inorganic salts and polymers is given with the solubility suitable for application,and its stability(active oxygen left rate)after two week's storage at 40 ℃ , 80 % relative humidity is above 90 %(without detergent powder)and above 80 % (with standard detergent powder).
