利用高分子溶液流过时间对浓度作图的外推值t0*处理粘度数据不仅简化了测量高分子溶液相对粘度的实验步骤,而且会使利用计算机或单片机采集和处理粘度数据变得更加简单易行.笔者在已有粘度测定设备基础上增加一套袖珍的用单片机加以控制的数据采集和处理装置,既可方便地得到高分子溶液粘度测量结果,又可提高实验的精确度.所有测量数据和处理结果可直接输入计算机完成绘图打印等后续工作.

If the flow time of the pure solvent t0*, obtained practically by extrapolating the flow time of polymer solution to zero concentration, was employed to determine the viscosity of polymer solution, the relative viscosity of polymer solution could be obtained by comparatively a much simpler experimental procedure. As a result, data sampling and data analyzing carried out by Single chip processor or computer became practical. In the present study, a new set of apparatus was designed so that data sampling and analyzing could be performed automatically. With the help of the designed apparatus, the relative viscosity of polymer solution was easier to be obtained. At the same time, the precision of the viscosity measurement was improved. All the data can be input into the computer automatically to complete the tasks such as plotting and printing.
