在线黏度测量过程中黏温补偿计算方法的误差研究

Study on Error of Viscosity Temperature Compensation Calculation Method of Online Viscosity Measurement Process

在线黏度测量在涂料聚合生产和涂装高分子材料应用行业中的应用越来越广泛。由于测量的对象各不相同,涂料高分子流体的流变特性也各不相同,给黏度测量带来了一些问题。针对在线测量过程中温度对黏度测量的影响,研究线性和非线性补偿计算不同方法计算结果的误差,提出了根据不同情况选择相应黏温补偿计算的现实解决方案。

Online viscosity measurement is applied more and more widely in polymer production and po-lymer material application industry. Because of the different objects of measurement, the rheologicalproperties of polymer fluids are also different, which brings some problems to the viscositymeasurement. In view of the influence of temperature on the viscosity measurement during onlinemeasurement, the error of the calculation results in different methods of linear and nonlinearcompensation calculation is studied, and a practical solution is proposed to select the correspondingviscosity temperature compensation calculation according to different circumstances.
