EFFECT OF CHEMICAL COMPOSITION ON WATER RESISTANCE OF A NEW TYPE GLASS ENAMEL PARTICLES
组分对一种新型搪玻璃粉料耐水性的影响

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.
