摘要
讨论了两种测量纸张灰份的方法,一种是X射线透射法,直接测量成纸灰份;另一种是激光透射法,间接测量网前箱与白水中的填料浓度以及填料留着率。
The measuring and control of ash content is an important part of the quality control system of the paper machine.Two measuring systems are discussed.One is the X ray method to detect the ash content of the paper sheet.The other is the laser method to detect the filler consistencies in the headbox and the white water,thus the filler retention is calculated.The ash content control systems made of these two measuring apparatuses are also studied respectively.Finally,the developping trend is proposed.
