在航空航天应用领域,用三氟氯乙烯齐聚物作为不可燃液压流体的候选物,现已证明具有很好的潜在优势。为了进一步研究不同分子组成(在商品CTFE流体中出现的)结构间的关系,现已设计出代表不同结构、特性优良的一系列化合物模型。通常描述液压流体在可用温度范围内的重要特性之一是粘度或粘度-温度特性。运用化学图解理论,导出氟氯碳分子的分子量、分子结构与粘度-温度特性关系的方程。
In aerospace applications, the use of chlorotrifluoroethylene oligomers as candidates for non-flammable hydraulic fluids has proven to have very good potential advantages. In order to further investigate the relationship between the structures of different molecular species (appearing in commercial CTFE fluids), a series of compound models have been devised to represent different structures and properties. One of the important characteristics that typically characterize the hydraulic fluid over the available temperature range is viscosity or viscosity-temperature characteristics. Using the chemical graph theory, the equations of the molecular weight, molecular structure and viscosity-temperature characteristics of CFCs are deduced.
