For manufacturers who use cutting fluids, rust, blisters, and fog lamps often appear when cutting fluids are used; in general, these phenomena are caused by the growth of bacteria. To eliminate these phenomena, you need to understand the classification of bacteria in the cutting fluid and living habits, and restrain the growth of bacteria at the source, so as to provide an ideal environment for the use of the cutting fluid.
1.2 Anaerobic bacteria habits: easy to breed in the anaerobic environment, most of them exist in cutting fluid and machine oil leakage.
Hazard: Digest the sulfur in the cutting fluid and machine tool oil leakage, and decompose it into oxygen sulfide gas, which has a serious smell of rotten eggs. It seriously affects the respiratory tract of the staff, and may also cause the PH value of the processing fluid to drop, which may cause rust and instability in the processing industry.
Solution:
1) Use a fungicide.
2) Keep the pH of the cutting fluid between 8.5 and 9.5.
3) Keep the concentration of the cutting fluid in direct proportion to the fungicide.
4) Test the water hardness.
5) Increase the concentration ratio.
2.1 Decreased ph value leads to decreased concentration; work also pollutes the bed; humid environment
Solution:
1) Increase the ph value, increase the concentration, and increase the bactericide.
2) Try to use deionized water for liquid preparation to ensure the concentration and use the liquid preparation method correctly.
3) Reduce the pollution of miscellaneous oil.
4) Control the potential difference.
Reasons for formation:
1) Concentration is too high.
2) Water quality is too soft.
3) Liquid level deviation.
4) Nozzle pressure is too high.
5) There are too many floating oils
Solution:
1) Check and adjust the concentration.
2) Detect the ph value.
3) Adjust the pressure of the nozzle.
4) Use a defoamer.
5) Detect the softness and hardness of the water.
6) The mailbox hydraulic pressure is not less than 80%.
Causes:
1) The machine tool system has a high oil content, especially the emulsified liquid will reduce the surface tension of the processing fluid, and it is easy to produce oil mist;
2) The oil mist collector is broken.
3) The agitation is large.
Solutions:
1) Reduce miscellaneous oil.
2) Use additives to increase the surface tension of the processing fluid.
3) Check the oil mist collector.
4) Use products with low oil content as much as possible while ensuring the normal operation of the oil mist collector.Reasons:
1) The concentration is too high.
2) Some harmful minerals gather together.
3) The emulsion is unstable.
Solution: Clean the machine often.Solution:
1) Apply hand cream before get off work and wash hands promptly after work.
2) Prevent workers from mixing some strong alkalis into the processing fluid.
3) Try to wear gloves.
4) Strengthen personal hygiene.
