玻纤湿法毡单位面积质量同位素在线测量系统

An On-line Isotopic Instrument for Measuring Mass per Unit Area of Fiberglass Wet-laid Mat

介绍了一种玻纤湿法毡单位面积质量同位素在线测量装置。它采用放射性测量手段在线检测玻纤湿法生产线上各品种毡的单位面积质量。经现场应用表明,该装置测量结果与称重法相比误差在±2 g/m2以内,能够实现相关玻纤湿法毡生产线上单位面积质量的准确在线测量。

An on-line instrument, which uses radioactive isotope to measure the mass per unit area of fiberglass wet-laid mat during production, is described. The actual use of this instrument has shown that the measurement deviation is ±2 g/m^2 as compared with weighing method, and thus it is capable of measuring the mass per unit area of fiberglass wet-laid mat on line accurately
