| 摘 要： | 在新闻纸废纸浆分别添加超微粒子双元及三元助留助滤剂，测定浆的Zeta电位及PCD胶体电荷量，留着率及滤水时间，优化最佳的助剂添加量。实验证明双元助滤助滤剂N1、N2的添加量均为0．4kg／t，Zeta电位为-5．9mV，PCD为-244．4ueq／L，留着率为75．37％，滤水时间为17．9s，协同效果最好。三元助留助滤剂。N1、N2的添加量均为0．3kg／t，N3的添加量为1．3kg／t时，Zeta电位为-4．4mY，PCD为-244．0ueq／L，留着率为81．34％，滤水时间为11．1s，效果最佳。

| Abstract: | Dual and ternary microparticle retention and drainage agents were added in the deinked ONP.PCD(particle charge detector),zeta potential detector and DFS(dynamics filtration system) were used as apparatuses in the experiment.The optimization results showed that in the dual-system,when the separating dosage of N1and N2 was(0.4)kg/t,zeta potential was-5.9mV,PCD was-244.4 ueq/L,retention was 75.37%,drainage time was 17.9s.The synergistic results showed that in the ternary microparticle system,when the separating dosage of N1and N2 was 0.3kg/t,N3 charges 1.3 kg/t,zeta potential was-4.4mV,PCD was-244 ueq/L,retention was 81.34%,drainage time was 11.1s. |
