废纸浆在浮选脱墨过程中,浮选之前已通过制浆工序将油墨和纤维分离,分离出来的油墨粒子通常是疏水的,油墨粒子与气泡相互碰撞,黏在气泡上,随气泡上浮从纤维悬浮液中排除。通常,油墨的去除随着气泡排除率的提高而增加,然而,气泡排出的同时也会排出纤 Waste paper pulp in the flotation deinking process, before the flotation process has been separated by ink and fiber ink, separated ink particles are usually hydrophobic, ink particles and bubbles collide with each other, stick to the bubble, with the bubble up from Fiber suspension excluded. In general, the removal of ink increases as the bubble elimination rate increases, however, the bubble is also discharged while discharging the fiber
