The structure of suspensions used to apply films by colloidal methods determines their key properties: thickness, surface roughness, and density. Direct structural studies of thin suspensions are significantly complicated, especially when the task is to determine changes in the structure induced by mechanical loads present in the film development process. This problem can be addressed through rheological studies. For this purpose, a method for normalizing the degree of thixotropy/rheopexy was devised to serve as a quantitative parameter for evaluating the structure of fluids based on their rheological properties. The trapezoidal integration method for calculating the flow curve area was demonstrated. The developed normalization method relies on a modified standard score equation that accommodates the peculiarities of flow curves. The normalized degree of thixotropy/rheopexy was employed to assess the structures of suspensions with identical compositions but subjected to varying maximum shear rates (200, 500, and 800 sec^–1) to plot the flow curves. The nonnormalized degrees of thixotropy for these suspensions differed by 11 to 12 times. The developed parameter allowed the deviation to be reduced to 16–19%. The normalized degree of thixotropy/rheopexy, along with the flow behavior index and effective viscosity, was used for the indirect evaluation of structural changes in suspensions with higher nanopowder content based on the rheological properties. This approach enabled the identification of four structural states of suspensions: isolated agglomerates, enlargement of the agglomerates accompanied by rheopectic flow, transition to Newtonian flow after the agglomerates deformed in the flow direction, and evolution of a regular network structure signified by thixotropic flow.

用于通过胶体方法涂膜的悬浮液的结构决定了其关键特性：厚度、表面粗糙度和密度。薄悬浮液的直接结构研究非常复杂，特别是当任务是确定薄膜显影过程中存在的机械载荷引起的结构变化时。这个问题可以通过流变学研究来解决。为此，设计了一种标准化触变性/流变性程度的方法，作为根据流体流变特性评估流体结构的定量参数。论证了计算流量曲线面积的梯形积分法。开发的归一化方法依赖于修改后的标准评分方程，以适应流量曲线的特殊性。采用标准化的触变性/流变性程度来评估具有相同组成但经受不同最大剪切速率（200、500 和 800 秒 –1 ）的悬浮液的结构，以绘制流动^曲线。这些悬浮液的非标准化触变度相差 11 至 12 倍。开发的参数可将偏差降低至 16-19%。触变性/流变性的归一化程度以及流动行为指数和有效粘度可用于基于流变特性间接评估具有较高纳米粉末含量的悬浮液的结构变化。该方法能够识别悬浮液的四种结构状态：孤立的团聚体、团聚体伴随流变流动的扩大、团聚体在流动方向变形后向牛顿流的转变以及以触变流为标志的规则网络结构的演化。
