摘　　要：研究了应用于小口径钢管内壁的一种新型搪玻璃粉料的填料粉中主要组分对其耐水性的影响.结果表明,随着网络生成组分SiO2含量的增加,硅氧网络形态发生变化,使粉料结构变得致密,其它网络生成组分Al2O3和B2O3有修补硅氧网络的作用,所以网络生成组分含量的增加提高粉料的耐水性;网络外组分阳离子的半径和“集聚”作用越大,粉料结构越致密,其耐水性越强,其中阳离子半径的作用大于它的“集聚”作用.The influence of the main components of a new type glass enamal particles on its waterresistance has been investigated. With increasing SiO2, Si-O networks become denser. The other components forming networks, such as Al2O3 and B2O3, can reinforce Si-O networks. So with increasing the components forming networks, the water-resistance of particles is improved. The larger the cations of the components outside the networks are, and the stronger their centralized action is, the denser the coating structures are, and the better the water-resistance of particles is. The action of the cation size is bigger than its centralization.
