As iron ion isdissolved in water when cast iron is being processed, it generates ferrichydroxide (in red); in the case of any presence of amine substances in cuttingfluid, in this case, highly active ferrous powder will react with aminesubstances to generate red substances; therefore, the cutting fluid will turnred. It is required to judge whether such cutting fluid becomes deteriorated, tosee whether its PH value, concentration and antirust performance is normal.
