摘要
Abstract
The influencing factors of uncertainty of melt volume flow rate(MVR)measurement for melt-blown polypropylene with high melt flow rate were discussed,and the uncertainty was evaluated according to JJF 1059.1-2012.The results show that the measurement repeatability and piston displacement are the main influencing factors of uncertainty.The expanded uncertainty of MVR of the melt-blown polypropylene is 27.3670 cm3/10min.关键词
