摘　　要：提出了制备用于评价生产线脱墨效果的浆页应遵循的基本原则,选择了纸页成形器法制备浆页,并提出不要对浆料进行p H值的调整和添加助留助滤剂,以正交实验证明当过滤网筛孔径选择在280～340目之间,浆页定量选择在90～100g/m2之间时,能最大程度地阻止细小油墨的流失,所制备的浆页可同时满足亮度、ERIC、尘埃度测定的需求。用此方案对某生产线进行了评估分析,亮度与E RI C的趋势分析结果基本一致。This paper points out a base rule on the laboratory sheets preparing for deinking effect evaluation of DIP product line, chooses sheet-former method to prepare laboratory sheets without pH adjusting or retention aid, and proves that it can prevent the micro ink particles lost most effectively, if the former with a screen between 280-mesh till 340-mesh and the sheets grammage between 90g/m^2 till 100g/m^2, by the orthogonal tests. The laboratory sheets can meet simultaneously the requirements from brightness, ERIC, dirt test. An evaluation of a production line was carried out with this scheme, and the trend analysis results of brightness and ERIC were basically same.
