Abstract

. The pitch contained in thermomechanical pulp (TMP) negatively affects paper quality, pulp, and the papermaking process. Serious pitch and stickies problems may occur in paper recycling processes. In this study, the effects of chemicals used to control the pitch in the TMP process were compared. The method used to analyze the pitch control effect was to perform image analysis after using a reagent that selectively stains only the hydrophobic pitch. Three different mechanisms, namely fi xation, detacki fi cation, and dispersion, were applied to solve the pitch problem from TMP. All the control agents were effective in pitch control, and, in particular, the agents related to fi xation and dispersion were found to be more effective in reducing the number and area of tacky particles per unit area in sheets and white water. However, it was dif fi cult to clearly identify the effect of both the detacki fi ers and the dispersant agents through image analysis after staining except for the fi xative agent.
不同机理TMP调沥青剂的效果比较
。热机械纸浆(TMP)中所含的沥青会对纸张质量、纸浆和造纸过程产生负面影响。纸张回收过程中可能出现严重的沥青和粘性问题。在本研究中,比较了在TMP过程中用于控制沥青的化学物质的效果。分析节距控制效果的方法是在使用一种仅选择性染色疏水性节距的试剂后进行图像分析。采用三种不同的机制,即固定、分离和分散,来解决TMP的节距问题。所有的控制剂都能有效地控制螺距,特别是与固定和分散有关的剂在减少片材和白水中单位面积粘粒的数量和面积方面更为有效。然而,染色后的图像分析,除固化剂外,很难清楚地识别脱粘剂和分散剂的作用。
