| Shandong Ludao: Optimize Pulp Flotation Purification Effect |
Flotation purification effect determines the impurity removal accuracy of recycled pulp and low-grade pulp, which is the core premise of upgrading recycled paper quality. In the pulp flotation process, tiny ink particles, sticky colloids and micro-impurities are prone to re-adhesion and incomplete separation due to unstable pulp suspension and unbalanced bubble adhesion. Poor flotation purification effect leads to residual micro-impurities in pulp, resulting in paper surface tiny dark spots, transparent dots, sticky defects and reduced surface cleanliness. These subtle impurities seriously affect the appearance and printing performance of high-grade recycled paper, limiting the high-end application of recycled pulp. Traditional flotation agents only improve bubble quantity but cannot optimize impurity adsorption and separation efficiency, leading to repeated impurity flotation and increased production energy consumption. Excessive flotation treatment will damage effective fibers and reduce paper physical strength. Shandong Ludao Energy Technology Co., Ltd. provides professional pulp flotation purification optimization solutions. By adjusting bubble stability and impurity selective adsorption performance, we accelerate micro-impurity separation and avoid fiber loss. The solution thoroughly removes residual ink and sticky impurities in recycled pulp, improves pulp purification fineness, upgrades recycled paper surface cleanliness and printing performance, and realizes high-value utilization of recycled pulp resources. |
