What is the shelf life of wire drawing oil?
2 Answers
Wire drawing oil generally has a shelf life of 5,000 kilometers. Higher quality wire drawing oil can last longer, reaching 8,000 to 10,000 kilometers. Introduction to wire drawing lubricants: These are lubricants used during metal wire drawing, typically divided into two types: dry wire drawing lubricants (commonly known as drawing powder) and wet wire drawing lubricants (water tank wire drawing lubricants). They serve as process lubrication materials in metal wire drawing operations. Performance characteristics of wire drawing lubricants: They can firmly adhere to the wire surface and enter the drawing die with the wire, effectively separating the two interfaces in the deformation zone; resistant to high pressure and temperature, maintaining continuity and lubricity without being destroyed, charred, clumped, or deteriorated under the high pressure and temperature rise conditions during drawing, demonstrating both physical and chemical stability.
I remember when storing spare car engine oil in the past, I found that unopened containers have a shelf life of about 3 to 5 years, especially synthetic oil which can last even longer. But the key lies in storage conditions—it should be kept in a cool, dry place, away from direct sunlight and high temperatures; humidity can degrade the oil quality, potentially turning it watery or causing sedimentation. Once opened, the bottle is exposed to air, and it's best to use it within 6 to 12 months. I've experienced increased engine noise with oil older than a year, so regularly checking the oil's color and viscosity is crucial. During oil changes, look for signs of thickening or cloudiness—if these are present, don't use it, as it could lead to increased part wear and higher repair costs.
