According to the DLVO theory, colloidal particles in suspension remain stable on account of electrostatic repulsion resulting from their surface charge.Aggregation can be induced by processes that reduce the surface charge, for example, by the displacement of surface ions by adsorbates and by pHchanges, as well as by ionic screening,and depletion forces.

根据DLVO理论,胶粒悬浮稳定性取决于它们的表面电荷产生静电排斥,减少胶粒表面电荷可诱导胶粒聚合,方法有: 被吸附物表面离子位移、改变pH以及屏蔽离子和势能损耗。
