流体型灭火剂表面张力测量中的误差分析

The error analysis in measuring surface tension of fluid extinguishing agent

介绍泡沫灭火剂、水系灭火剂等流体型灭火剂产品表面张力测量方法以及测量过程中容易出现的各种误差,对其产生的原因进行分析。可通过恒温水域或低温试验槽等控温装置确保测量温度在合理的范围内,尽量减小温度造成的测量误差。应保证测量中泡沫溶液质量分数的精确性;在测量时要注意保持铂金环的弧度和水平度,铂金环使用后应注意清洗并高温灼烧。

Present the errors appeared during the process of measuring surface tension of fluid extinguishing agent, just like foam extinguishing agent and water based extinguishing agent. Analysis the causes of the errors appeared and give the methods or requirements to reduce the errors.
