复合改性水玻璃的研究

The research of compound modified sodium silicate

介绍了水玻璃改性剂及改性水玻璃的合成工艺、性能及其在火车车辆零件的铸造生产中的应用情况 .所合成的水玻璃改性剂可大幅度提高水玻璃的粘结性能和溃散性 ,有利于解决水玻璃砂的再生和回用问题 .

Preparation, properties and application of modifier used in sodium silicate and modified sodium silicate are introduced,binding ability and collapsibility of sodium silicate are improved largely by addition of modifier in sodium silicate.It is liable to be reclaimed for moulding sand.
