[Case Study on Trouble Improvement] Decreased Ink Removal Ability
Improvement case
Excellent ink removal even under high temperature conditions! Improvement of whiteness with deinking agents effective at high temperatures.
As summer arrived, the water temperature in the DIP manufacturing process increased, exceeding the effective temperature range for typical deinking agents, resulting in a decrease in whiteness and ink removal rates. To address this, we added the high boiling point product 'DIA-Z-300' to the pulper. This resulted in a 1 point increase in whiteness and a reduction in residual ink, allowing us to enhance whiteness without compromising productivity. 【Case Summary】 ■Issue - With the arrival of summer and the rise in water temperature in the DIP manufacturing process, typical deinking agents became ineffective, leading to a decrease in whiteness and ink removal rates. *For more details, please refer to the PDF document or feel free to contact us.
