CZAH-01 is one kind of chelating agents designed for pulping and bleaching, it has a strong ability

to bind with dissolved metal ions. Under the alkaline environment, CZAH-01 has excellent

performance in binding metal ions, especially for the highly-charged metal ions. It’s proven

stable under high temperature(200°C) and high PH. It’s more effective in practice compared with

other organics in resistance to acid and alkaline or chlorine oxidation. By chelating metal ions and

clear their catalysis decomposition to oxidant like H2O2 or CLO-, it could effectively prevent

the ions from being deposited as residue on your equipment. It could also be used to protect the pulp fiber, prevent the pulp return yellow and enforce the effect of bleach dispersity
