本项目拟采用激光检测粒径与其他特性分析手段相结合的方法，研究办公废纸和旧新闻纸回用时抄造白水微细胶黏物颗粒粒径及其特性的变化，系统分析温度、压力、pH值、化学药品，以及生物酶等因素对微细胶黏物颗粒的尺寸及其特性的影响规律，特别是对微细胶黏物的失稳规律进行研究，在此基础上，研究微细胶黏物体系再次稳定导致障碍的机理。本项目的研究拟解决抄纸时尤其是废纸浆抄纸时白水微细胶黏物导致的日益严重的负面作用，从而为胶黏物问题的有效控制提供理论和技术支撑。

A method combined particle size measurement with characteristics analysis will be applied in this project to research the variation of microstickies size and its characteristics in white water of mixed office wastepaper (MOW) or old newsprints (ONP). The effects of temperature, pressure, pH values, chemical and enzyme on microstickies size and its characteristics will be systematically analyzed. Moreover, features of unstability of microstickies existed in white water will be also studied. On the basis of this, mechanism of the obstacle resulted from the new stability of microstickies system can be researched. The work of this project intends to solve the growing and negative effects generated by microstickies in white water in the procedure of papermaking. The results will provide powerful and technical supports for the control of microstickies.
