摘要

分析了与硅溶胶粘度性能相关的各项因素

包括硅溶胶的SiO2 含量、温度、pH值和胶粒的形状、大小、致密性、水化层的厚薄、荷电性以及硅溶胶中存在的电解质、高聚物等等。粘度与硅溶胶的微观结构有关

是硅溶胶质量的重要指标。在硅溶胶的生产或使用中

都应对粘度指标有足够的重视

Abstract

Various factors related to the viscosity of silica sol

including SiO 2 content

temperature

pH value and shape

size and compactness of colloid

thickness of hydrated layer

electric charge electrolyte as well as polymetre etc.

were analyzed. Viscosity related to microstructure of silica sol is a key index for silica sol quality. Sufficient attention should be paid to the viscosity index in production and usage of silica sol.
