Several factors affecting the anti-rust performance of cutting fluid

The following small series details the anti-rust performance of the cutting fluid to better improve the processing quality of the cutting workpiece.

1, the anti-rust performance in the cutting fluid, that is, the quality of the anti-rust agent itself added to the cutting fluid. High-quality anti-rust additives can bring good anti-rust effect, which is particularly important.

2, the amount of anti-rust agent added in the cutting fluid, with enough anti-rust agent added to ensure that the cutting fluid is diluted to meet the target anti-rust needs.

3. Synergistic anti-rust effect. The value is the other component additives in the cutting fluid to provide a certain amount of secondary rust prevention subsidies.

4, the surfactant boost effect, no matter how good the anti-rust agent can not react evenly with the clean metal surface is useless;

5, the appropriate ph value, the alkaline environment is conducive to slowing the speed of movement between metal electrons, usually ph higher than 9 is the best, but considering the corrosion of the cutting fluid acid base, operator adaptability, etc., the cutting fluid ph value is usually positioned between 7.5 and 9.5.

6, the number of calcium and magnesium ions in the water quality, because the anti-rust agent in the cutting fluid is easy to react with the calcium and magnesium ions in the water to produce water-insoluble substances.

7, the workpiece storage environment, the humidity of the air in the storage environment, the temperature of the workpiece rust prevention time is also very important.

Do a good job of cutting fluid rust resistance, better improve the machining quality of the cutting workpiece, improve work efficiency.
