Does water - based metal working fluid deteriorate after a period of use?
2022-10-27
This is due to iron processing, iron ions dissolved in water, the formation of iron hydroxide (red); And if there are amines in the cutting fluid, in this case, highly active iron powder will react with amines to form red substances; Therefore, the cutting fluid will turn red. Judge whether the cutting fluid is metamorphic, see its PH value, concentration, rust resistance is normal.
