摘要
纸厂中的沉积物通常含有多种组分,其主要来源于机械浆、回用纤维、涂布损纸以及过程添加剂等多种原料.通常这些沉积物中某一组分可作为沉积作用的主要引发剂,同时也可作为其他原料之间的粘合剂,因此对这种引发剂进行鉴定和处理对减少胶粘物的沉积具有重要意义.另一方面,在胶粘物沉积现象严重的过程中,其还可以帮助有效地鉴别二次胶粘物.然而,要准确鉴别这种引发剂还有一定的难度.作者对纸厂胶粘物的沉积、浆料、沉积机理以及沉积物本身的组成等进行了研究,以期建立一种可靠的方法,有效地鉴别目前以及将来引发沉积物沉积的引发剂.
Deposit problems at a mill will often have components from multiple sources including mechanical pulp,recycled fiber,coated broke,and process additives.In these deposits,there is often one component serving as both a primary trigger for deposition as well as a binder for other materials.Identification and treatment of this trigger can significantly decrease deposition and also help to identify secondary deposit problems more effectively.In the middle of a severe deposit outbreak,however,it can be difficult to identify a primary trigger.Consideration of a mill＇s deposit history,its furnish,and the texture and composition of the deposit itself can help to establish a solid methodology for efficiently identifying the primary trigger of deposition in current and future deposit problems.
