The PH value of drawing oil usually decreases in the process of use, and the decrease of PH value can cause the rustiness and antibacterial ability of drawing oil to deteriorate.

When the concentration meets the requirement, but the PH value is not up to the specified value, we should use triethanolamine, sodium carbonate, etc. to improve the PH value of the working fluid in time and control it within the specified range. (Drawing oil)

The reasons for the decrease of rust prevention are the consumption of antirust agent, the decrease of PH value, the propagation of bacteria, and the low concentration of drawing oil, etc. These reasons should be solved, and if the consumption of antirust agent is too much, the antirust agent can be added to the working fluid of drawing oil. (Drawing oil)

Percentage concentration and PH value of wire drawing oil is checked once a day, the concentration is stable to ensure the lubricating performance of wire drawing oil, so it should be regularly replenished with new copper wire drawing oil to stabilize the PH value at 7.0 to 8.0.

PH value is lower than 7.0, drawing oil in the oil and water may be separated, you can add a certain amount of low-concentration PH blending agent to adjust.

However, too high a PH value will produce a tendency to precipitate soap, resulting in the tower wheel and the mold is not clean, drawing oil lubricating properties decline.
