纸张灰份的在线检测及灰份仪的研制

The on-line measurement of paper ash and ash,meter

灰份是衡量纸张质量的主要指标之一,实行灰份在线检测及控制可以降低纸浆消耗,提高纸张质量及生产效益。本文全面讨论了灰份测量的方法,灰份仪设计要点及参数相互关系,最后展示了根据国家“八五”攻关项目研制的我国第一台纸张灰份仪。产品的初步应用表明:仪表功能完备,性能优良,可以满足在线检测及控制的要求。

The ash content is one of important specifications of paper quality. With on-line instrument and control system of ash, the product cost could decrease, and that the benefit increase greatly. The on-line measuring technique, as well as the discussion about the main parameters,is present. A design cquation is proposed, which reveals the relationship of all main factors in instrument. Finally, the first Chinese ash instrument, that shows the advantages of the instrument for industrial application,is developed.
