We consider a model for a two-component solution which consists of a chemically reacting solvent and a chemically inert hard-sphere solute. A directional associative interaction between the solvent molecules promotes the formation of a network. A multidensity associative Ornstein-Zernike equation is solved analytically using the Percus-Yevick approximation. On the basis of the analysis of the osmotic compressibility, an instability curve for different parameters of the model dispersion is constructed. It is shown that concentration and size of colloids affect the formation of associative complexes in a solvent and directs in such a way the location and behavior of the spinodal curves. The effective interaction between colloids is calculated and discussed. Copyright 1999 Academic Press.
我们考虑一种双组分溶液模型，该模型由发生化学反应的溶剂和化学惰性的硬球溶质组成。溶剂分子之间的定向缔合相互作用促进了网络的形成。使用珀库斯 - 耶维克近似法对多密度缔合奥恩斯坦 - 泽尔尼克方程进行了解析求解。基于对渗透压缩性的分析，构建了模型分散体不同参数的不稳定曲线。结果表明，胶体的浓度和大小会影响溶剂中缔合络合物的形成，并以这种方式指导旋节线曲线的位置和行为。计算并讨论了胶体之间的有效相互作用。版权所有1999年，学术出版社。
