| 摘 要： | 废纸机械法不可能除去的胶粘物,必须用化学法除去。化学法包括了改变胶粘物粘性和避免沉积的化学处理;除去杂质后产品没有明显缺点的化学处理和胶粘物形成时能除去的化学处理。废纸化学处理的具体方法有:5.1化化学吸附法废纸吸附技术包括了依靠接触来除去胶粘性质,这种胶粘性质常与潜在胶粘物的表面有关联。应用这些技术,有可能稳定溶解物和胶体物(DCS)并避免它们的附聚(agglomeration)。化学吸附能稳定杂质粒子但不会使它们的大小改变。废纸为了使胶粘物粒子更具亲水性和减少发粘性,它的表面需要用其它物料覆盖,可以用有机物(如表面活性…

| Abstract: | Stickies problems in recycling were introduced in this paper which were divided in six parts at all. They are potential sources ofstickies and their chemical nature; classification and deposits mechanism of stickies as well as harmfullness from stickies; methods forquantiative characterization and qualitative analysis of stickies; mechanical control methods for stickies; chemical methods for stickiescontrol; stickies control programme in paper mills and future trends in stickies research studies. |
