Principle of Catalytic Degreasing Reaction
Author:
Catalytic Degreasing Reaction Mechanism
Pre‑flushing: Prior to degreasing, introduce nitrogen gas to thoroughly dilute and purge the furnace atmosphere.
Debinding: Introduce concentrated nitric acid containing a catalyst, maintaining the furnace chamber at 95–125°C to induce catalytic cracking of the binder in the workpiece.
Post‑flushing: After degreasing, nitrogen is introduced to thoroughly dilute the formaldehyde and nitric acid generated by the pyrolysis of polyoxymethylene.
