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.

The goal of maintenance and management of water-based metal processing fluid is to make its pH value, concentration ratio, bacteria content and other technical indicators within the set range, so as to achieve the extension of service life. No matter how good the performance of water-based metal processing liquid is, if you do not pay attention to the daily maintenance and management,

Alkalinity: long-term exposure to strong alkaline substances. Acidity: Source of any contaminating acid will eventually lower pH and pH levels below 7 will irritate skin. Solvents: Solvents remove the natural protective oils from the skin, leaving the skin more exposed to chemical immersion.

This is because the lubricity of water-based metal processing liquid is not as good as that of oil-based metal processing oil, so this situation may occur. The solution is to use emulsified water-based metal working fluid with better extreme pressure performance to reduce dilution, increase the concentration of the working fluid, and increase the amount of lubricant injected into the working area.

In the working state, the processing fluid can not be eliminated in time due to the formation of a large number of foam spray, mainly due to A. The pressure is high, the current is fierce; b. Too high concentration; c. Soft water quality; d. The liquid level is too low; e. The system defoaming performance decreases, c. Soft water quality;d. The liquid level is too low;e. The system defoaming performance decreases, etc
