VERPAP-FDI (Powerful deinking agent for waste paper)

VERPAP-FDI is a very powerful deinking agent. It helps removing various inks, (black/coloured) from cellulose fiber without damaging its chain structure. Due to its excellent emulsification power, VERPAP – FDI prevents redeposition of ink on the cellulose fiber. VERPAP – FDI can de-ink both imported waste paper as well as local waste paper effectively to make white paper of the desired quality.

APPLICATION
VERPAP- FDI is recommended to add 0.2 to 1.0% on the weight of the pulp in the pulper for loosening the ink and separation from the pulp fibers. VERPAP – FDI is added in Hydrapulper or Breaker beater along with other chemicals like caustic soda, sodium Hypo chloride, sodium silicate, Hydrogen peroxide in required concentration. Percentage of above chemicals depending upon the type of waste paper, type of loading ink characteristics etc.

Factors influencing deinking operation:
