摘要
应用NMR技术、激光拉曼光谱和硅钼酸方法研究了碱性硅铝酸盐聚合反应中铝酸根离子和硅酸根离子的存在状态及其变化.发现聚合反应是低分子量硅铝酸根离子之间或低分子量硅铝酸根离子与低分子量硅酸根离子之间的反应.
This paper describes a study of polymerization of aluminosilicate. The state and change of silicate and aluminate in starting materials and reaction mixture have been studied by using NMR techniques, Laser-Raman spectroscopy and silicatemolybate method. It was found that the reaction between aluminate and silicate is very fast and silieate itself is degraded. Therefore, the process of further polymerization of aluminosilicate is the polymerization of low molecular species of aluminosilicate or silicate. It can be explained by using this point of view that the rate of polymerization of aluminosilicate is changed with variation of concentration of reagents.
