Hello!
We are using Chevron Rykon Oil AW ISO 46 in our laminator machine. The oil gets heated up to 250 degrees F and then pumped through a metal drum. The drum gets heated up to melt lamination film as it is rolled over the paper.
I found out that we need to change the oil every 3 to 6 months. The oil gets darker over time. If we leave it on longer, the machine builds up sludge (and we know where that leads to).
I was wondering why does the oil get darker. Is it burning up? I thought in a closed system like this, it doesn't get any contaminates and should stay the original color. And is there any other oil we can use that would be similar, like a synthetic (if it isn't syn already) that might work better?
Thank you.
