中文摘要:
      目的 纸基包装材料多采用水性油墨印刷,在此类废纸回用过程中通过增加水性油墨颗粒的粒径,可以有效避免或减轻由于其粒径过小而造成的在纤维上的二次沉积与吸附,也可增加水性油墨废水处理过程中小颗粒水性油墨的去除效果。方法 模拟废纸碎浆体系中小颗粒水性油墨在不同助剂及不同pH条件下粒径的改变情况,从而得到不同助剂的使用效果。结果 添加一定量的无机助剂CaCl2、有机助剂CTAB或改变体系的pH值,均能增加无纤维时的水性油墨颗粒粒径;但纤维存在时CTAB并不能起到预期效果。结论 当体系pH值为5、CaCl2浓度为0.20 mol/L、CTAB浓度为0.12 mmol/L时,水性油墨颗粒的粒径相对较大,分别为3.8, 1.0, 0.5 μm;但当有纤维存在时,添加CaCl2的效果降低,最佳浓度是0.30 mol/L,粒径为2.7 μm;CTAB在纤维存在时并不能促进水性油墨的絮聚,反而会造成纸浆光学性能的降低。
英文摘要:
      The work aims to effectively avoid or reduce the redeposition and adsorption of water-based ink particles onto fibers due to excessively small particles by enhancing their particle size during the recycling process of this kind of wastepaper, and also improve the removal efficiency for the water-based ink of small particles during the wastewater treatment, as the paper-based packaging materials are printed mostly with water-based ink. The change in particle size of water-based ink of small particles in the wastepaper repulping system was simulated under different additives and pH values. Adding a certain amount of organic additives CaCl2 and CTAB or adjusting the pH in the system could increase the particle size of water-based ink particles without fibers. However, there was no good effectiveness for the addition of CTAB with fibers. The particle sizes of water-based ink particles are relatively larger (3.8, 1.0, 0.5 μm respectively), when the pH value of the system is 5 and the concentrations of CaCl2 and CTAB are 0.20 mol/L and 0.12 mmol/L, respectively. However, with the presence of fibers, the effectiveness is decreased after adding CaCl2, the optimal concentration is 0.30 mol/L and the particle size is 2.7 μm. For CTAB with fibers, it cannot promote the flocculation of water-based ink and but instead reduces the optical properties of paper pulp.
