常见问题解答


1.什么是熔体流速测试仪? 

 

熔体流动速率测试仪(也称为熔融指数测试仪)是一种用于测定热塑性材料在熔融状态下的流动特性的专用仪器。它测量

     在规定的温度和载荷条件下,在10分钟内通过标准口模的熔体的质量(MFR)或体积(MVR)为材料流变学评估提供必要的数据。


2. MFR与MVR有何区别?  


- MFR:通过测量规定时间内挤出的物料质量来确定,单位为g/10min。  

- MVR:通过记录活塞在固定时间内移动的位移,或活塞行进固定距离所需的时间来确定,单位为cm³/10min。  

当材料在测试温度下的熔体密度已知时,两者可以进行换算。

 

3. 测试依据哪些标准?  


该仪器符合主要国际和国家标准,包括:  

- GB/T 3682.1-2018(中国)  

- ISO 1133:2011(国际)  

- ASTM D1238-2013(美国)

 

4. 为何测试结果有时差异显著(可达数倍)?  


粉末材料的数据波动较大,通常源于测试过程中发生热降解或交联反应。添加适量的稳定剂(如抗氧化剂)可有效改善这一问题。

 

5. 测试值异常偏低的原因有哪些?  


常见原因包括:  

- 活塞或导向套上积碳导致摩擦增大,阻碍活塞平稳运动;  

- 导向套不对中,使活塞杆倾斜;  

- 料筒或口模清洁不彻底,有残料留存。 排除以上因素对保证测量精度至关重要。

 

6. 日常保养有哪些建议?  


- 料筒与口模:每次测试后趁热清洁,防止残留物固化后难以清除;  

- 砝码:定期检查有无油污或锈蚀,保持表面洁净;  

- 加热系统:定期清除加热单元上的积尘,确保散热良好;  

- 长期存放:彻底清洁各部件,涂抹防锈油,置于干燥环境;重新使用前,建议用标准参考物质校验仪器精度。

 

7. 7英寸触摸屏的优势是什么?  

7英寸全彩触摸屏提供直观的人机交互界面,响应灵敏、操作便捷,支持中/英文双语切换,特别适合初次接触该类设备的用户使用。

 

8. 温控精度如何?  

仪器温度范围为室温~350℃,控温精度达±0.1℃,可确保测试结果的高精度和良好重复性。

  

9. 可测试哪些材料?  

本仪器适用于多种热塑性塑料,包括但不限于:  

- 聚乙烯(PE)、聚丙烯(PP)  

- ABS树脂、聚碳酸酯(PC)  

- 尼龙、氟塑料及其他工程塑料  

- 橡胶及相关石化产品

 

10. 如何确保测试结果的准确性?  


为保证数据的可靠性与重复性,建议:  

- 定期校准温度和位移传感器;  

- 每次测试前彻底清洁料筒和口模;  

- 使用认证标准物质进行日常验证;  

- 确保砝码加载准确无误;  

- 严格遵照相关标准规定的测试条件进行操作。
