丙烯酸-马来酸酐共聚物在碱性无磷洗涤剂中的应用研究

The Studies on Application of Acrylic Acid-maleic Anhydride Copolymer in Basic Phosphate-free Detergent

去掉磷酸钠后 ,洗涤剂的去污力有所降低 ,而其他碱性助剂如硅酸钠、碳酸钠、 4A沸石等的大量加入又会使洗涤剂pH值升高 ,灰分沉积严重。研究了丙烯酸 马来酸酐共聚物 (AA -MA)在碱性无磷洗涤剂中的应用 ,证明丙烯酸 马来酸酐共聚物具有很好的螯合性能和分散性能 ,应用在洗涤剂中能缓冲pH值 。

After phosphate-prohibition in detergent,the detergency of detergent becomes lower ,but other basic builders, such as sodium silicate, sodium carbonate and 4A-zeolite can promote pH value and add to ash deposition.This paper studies the application of acrylic acid-maleic anhydride copolymer in basic phosphate-free detergent. The result show that acrylic acid-maleic anhydride copolymer have excellent chelate ability and dispersibility.It can buffer pH value and anti-redeposition using in the phosphate-free d...
