As temperatures begin to drop, it’s crucial to consider how water-based metalworking fluids are stored and transported. Unlike oils or other industrial fluids, these fluids are highly susceptible to freezing, which can result in separation of components, diminished effectiveness, or even permanent damage.
Why Freezing Matters
When water-based metalworking fluids freeze, the water and other components can separate, leading to instability in the formula. Once the fluid thaws, it may not fully regain its original consistency, impacting performance and potentially causing equipment issues. This separation can also result in increased bacterial growth, which leads to short sump life and poor machine tool lubrication.
Storage Best Practices
To prevent freezing, it is essential to store water-based metalworking fluids in temperature-controlled environments, ideally above 5°C (41°F). Outdoor storage should be avoided unless containers are properly insulated. If indoor storage isn’t an option, you could consider using heated containers or moving fluids indoors during particularly cold spells.
Transport Considerations
When transporting these fluids during winter months, be aware of the risks posed by cold weather. Ensure that delivery trucks are equipped with heating capabilities or that the fluids are properly insulated. If fluids do freeze during transport, it’s essential to warm them slowly and stir thoroughly before use to prevent any damage to the emulsion.
IMPORTANT: Always check with your manufacturer if you think the product may have been frozen. The manufacturer can provide instructions on how to proceed.
Being proactive about winter storage and transport not only extends the life of your metalworking fluids but also ensures that your machining operations run smoothly throughout the colder months.
