Product Description

Six major considerations when purchasing defoamers for papermaking

1. Defoaming agent system: Look at the proportion of alcohol, emulsifier, etc. in the defoaming agent to the total amount of defoaming agent.
2. Dynamic defoaming ability: observe the dynamic defoaming effect in small spaces and in open spaces.
3. Static defoaming ability: Less foam produced during the packaging process and fast defoaming indicate good defoaming effect.
4. Applicable PH value: between 6 and 9.
5. Long-term effectiveness: Look at the surface tension of the surfactant.
6. Applicability on the machine: Observe defoaming changes by adjusting temperature and dilution frequency.

Product Description:
RK-50P is a mid-temperature polyether ester defoamer suitable for use in paper-making industry and water treatment.
