来自公共和私营部门的压力继续增加所有高容量等级的纸张回收。在新闻纸中，压力是将回收的ONP从目前的40%提高到更高的值。与此同时，在过去的十年中，从凸版印刷到胶印印刷的转变正在发生。胶印机的速度不断提高，印刷质量也不断提高。这些成就是通过使用具有更高油墨-纤维粘合力的油墨实现的。为了与更高纤维粘合力的油墨保持同步，新的脱墨剂，高醇嵌段共聚物类型正在进入市场。这些嵌段共聚物可提高再生纸的白度，减少油墨残留，最终生产出高质量的再生纸。本文报道了新型高醇EOPO嵌段共聚物的性能，并与高醇EO/PO无规共聚物和脂肪酸型共聚物进行了对比分析。
Pressure continues from both the public and private sectors to increase paper recycling in all high volume grades. In newsprint, the pressure is to increase recycled ONP from the current level of 40% to a higher value. Meanwhile, through the past decade, a shift is occurring from letterpress to offset printing. Offset press speed is increasing and better print quality is being achieved. These achievements have been attained using inks having greater ink-fiber adhesion.To maintain pace with higher fiber bond strength inks, new deinking agents, high alcohol block copolymer types are entering the market. These block copolymers make it possible to increase brightness, reduce residual ink and ultimately produce high quality recycled paper.The properties of the new high-alcohol EOPO block copolymer type and the results of a comparative analysis to the high-alcohol EO/PO random copolymer and fatty acid types are reported.
