Flotation Deinking Process For Paper Making


Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp, while flotation deinking is an effectie technology with better energy saving and emission reduction in paper making process, less fiber loss, high yield, light pollution.

Flotation Deinking Process Technology

It utilizes the different surface energies of the particle components such as fibers, fillers and inks to achieve separation. Hydrophobic particles or particles that are converted from hydrophilicity to hydrophobic particles by means of surfactant to adsorb air bubbles on the pulp suspension and are separated from the hydrophilic pulp fibers by buoyancy. Usually the ink particles is 10~100mm, the flotation deinking effect is best.

Flotation Deinking Machine Feature

1. Mainly used for deinking recycled pulp, can effectively remove the ink, light impurities and so on.

2. High efficient flotation, high consistency scum, less fiber loss.

3. Low power consumption, less maintenance, low operation cost.

4. One set can achieve 4-5 stages of flotation, less occupied area.
