摘　　要：以旧杂志纸为原料,通过控制变量法进行单因素分析,研究碎浆浓度、时间及温度对脱墨效果的影响,并用正交实验优化了脱墨工艺条件。其最佳的脱墨工艺条件为:碎浆浓度12%,碎浆时间40 min,碎浆温度50℃;在该条件下,旧杂志纸脱墨浆的ERIC值、白度、抗张指数和耐破指数分别为123.72 mg·kg-1、77.19%、39.45 N·m·g-1和2.96kPa·m2·g-1。Old magazines paper （OMG） was used as the raw material, and single factor analysis was performed to study the effect of pulping consistency, time and temperature on the deinking results, and then orthogonal experiment was applied to optimize the deinking technological conditions. The results showed that the optimum conditions for the deinking of OMG are as follows： pulping consistency is 12%, time is 40 min and temperature is 50~C. Under this condition, the effective residual ink concentration （ERIC）, whiteness, tensile index and burst index ofdeinked pulp are 123.72 mg·kg^- 1, 77.19%, 39.45 N·m·g ^-1 and 2.96 kPa·m^2·g^- 1 respectively.
