聚乙二醇黏滞系数与表面张力系数相互关系研究

Study on Correlation between Viscosity and Surface Tension Coefficients of Polyethylene Glycol

分别利用落球法和拉脱法测量了聚乙二醇在不同温度下的黏滞系数和表面张力系数,利用Origin软件拟合实验数据,得到了描述聚乙二醇黏滞系数与表面张力系数相互关系的经验公式,对于聚乙二醇未知相关数据的预测具有指导意义.

Firstly, with the respective use of falling-ball method and that of pulling escape, the authors of this paper measure the coefficients of viscosity and surface tension of polyethylene glycol. Secondly, after the fitting of the measured experimental data by Origin, they obtain the empirical formula to describe the correlation between viscosity and surface tension coefficients of polyethylene glycol,which have directive significance for the relative unknown data of polyethylene glycol.
