摘要:熔体质量流动速率(MFR)是大多数热塑性塑料重要的特征性能和出厂检验项目之一,准确测定材料嫆
体流动速率值具有极其重要意义。2011年国际标准化组织发布了修订的MFR测定方法标准《ISO1133-1:2011塑料
热塑性塑料熔体质量流动速率(MFR)和熔体体积流动速率(MWR)的测定第一部分:标准方法》,新修订的ISO标
准与现行国家标准《GB/T3682~2000塑料热塑性塑料嫆体质量流动速率和嫆体体积流动速率的测定》在技术上存在
较大差异。通过对上述国内外标准的对比及初步验证试验结果的分析,提出了以下标准化工作建议:一是尽快开展试
验验证,及早修订现行熔体流动速率试验方法国家标准,满足国内有关单位使用;二是熔体流动速率标准样品的研复
制过程中应积极探讨采用新的国际标准;三是国内仪器生产商应关注国际标准变化,确保仪器与新发布的标准一致
满足用户需求;四是建议国内塑料标准化技术委员会尽快开展标准转化工作,及早修订CB/T3682~2000,为各类
品标准采用新方法提供依据。

Abstract: The melt mass-flow rate (MFR) for the most thermoplastics is one of important feature of
properties and factory inspection items, so accurate determination of MFR value had very important signifi
cance. In 2011, the international organization for standardization (ISO)released the revised MFR method
for the standard ISO 1133-I: 2011 Plastics-determination of the melt mass-mlow rate (MFR) and melt vol
ume-mlow rate (MVR of thermoplastics-part 1: Standard method, which was technically quite different
from existing national standards. Based on the above mentioned standards at home and abroad comparison and
preliminary test results of analysis, suggestions of standardization work were put forward as the following
firstly, experimental verification should be carry out soon to revise current test method for MFR of the national
standard and meet the domestic needs: secondly. the new international standards should be actively adopt i
the preparing process of standard samples of MFR determination; thirdly, in order to meet customers needs
domestic manufacturers should pay close attention to changes of international standards, ensuring that the in-
struments agrees with new standards; fourthly, the domestic plastics Standardization Technical Committee
should as soon as possible do the job of standard transformation and revision of the standard GB/T 3682
2000, providing the basis for various types of product standards adopting the new method
