Persistent foam is a common bottleneck in paper pulp production. Foam can occur during pulp cooking, washing, screening, circulation and recycled pulp processing, reducing efficiency and affecting process stability.
JY-220J Pulp Industry Defoamer is a silicone defoamer route for paper pulp foam-control applications. It is relevant for wood pulp, straw pulp, recycled waste paper pulp and mixed pulp systems.
The product should be evaluated by foam knockdown, long-term suppression, compatibility, temperature resistance, pH condition, drainage influence and whether it creates deposits or paper defects.
For comparison, buyers can review JY-210J Pulp Industry Defoamer and JY-230J Pulp Industry Defoamer in the same test system.
A useful sample request should include pulp type, foam position, process temperature, pH, current defoamer, dosage, test method, annual consumption and required documents.
