De-inking chemicals are essential for recycled paper production, enabling mills to remove printing inks, adhesives, stickies, and other contaminants from recovered fibre while preserving pulp strength and brightness. Venus Goa supplies surfactant-based de-inking formulations and process aids optimized for flotation and washing de-inking lines.
How de-inking works
In the pulping stage, recovered paper is disintegrated in alkaline or neutral conditions with de-inking surfactants that detach ink particles from fibre surfaces. During flotation, fine air bubbles carry ink and hydrophobic contaminants to the surface for removal; in washing de-inking, dispersed ink is diluted and washed out with process water. Effective chemistry balances ink detachment, foam control, and fibre retention.
Venus de-inking solutions
Our de-inking agents combine nonionic and anionic surfactants for wetting, dispersion, and collector action on flexographic, offset, and digital inks. Products are selected for compatibility with enzyme treatments, bleaching sequences, and closed-loop water systems. Proper de-inking improves final brightness, reduces dirt count, and lowers reject rates—directly impacting mill economics and product grade.
