Cutting solution soap? How to avoid?
June 23, 2022
During the use of the cutting fluid, layered phenomena will sometimes occur, and the precipitated oil and soap that is insoluble in water. Cutting solution oil and soap, indicating that the cutting fluid is deteriorating, not only does it not achieve the effect of the cutting fluid, but it will also produce a irritating odor, which will cause pollution to the surrounding environment, which is not conducive to the health of workers.
How is this phenomenon from? What should I avoid? What is the cause of the phenomenon of soap? 1. The water quality is too hard The water with the emulsion solution is too hard. When an emulsifier encounters CA2+, MG2+ions in hard water, combines with CA2+and MG2+ions to form a saponification substance! 2. The cutting fluid is decomposed by microorganisms in the water The fatty oil and unsaturated fatty acids contained in emulsification solution are easily eroded by microorganisms. Microbial, mold, mold, and algae that often encountered in emulsification solution. These three types of microorganisms have adversely affect the stability of emulsification. Many emulsifiers contain sterilizers, but their additions are limited by oily dissolving. When the configuration of the emulsion, the concentration of the sterilizer is further reduced, which reduces its sterilization effect. After the emulsification solution is eroded by microorganisms, compounds such as unsaturated fatty acids in emulsion solution are decomposed by microorganisms, destroying the balance of emulsion, generating oil analysis, increased soap and acid values, and further causing emulsion liquid corruption. How to avoid cutting liquid analysis soap? 1. Dilute the emulsification solution should be diluted with tap water or soft water to avoid the use of groundwater containing E. coli and inorganic salts and surface water with many microorganisms. 2. When injecting a new solution, first remove the cutting fluid and oil from around the machine tool and the liquid supply system, and add the new solution after disinfection with a bactericide. It is equivalent to corrupt bacteria that are not cleaned. 3. To manage the supply solution, keep the emulsion work under the specified concentration, and the thin concentration of the emulsion solution promotes the reproduction of bacteria. 4. When the pH value is found to have a tendency to decrease, the pH increase agent should be added to keep the pH value of about 9. When the pH value of the emulsification fluid exceeds 9, it is difficult to reproduce by microorganisms. 5. When long -term shutdown such as holidays, regularly drums into the air into the liquid box to prevent the reproduction of anaerobic bacteria, and it can also remove the odor. 6. While paying attention to preventing oil leakage from mixing, install a device that can quickly remove the oil leakage. 7. Effective chipping methods are used to avoid chipping into the liquid box. 8. If you are aware of the signs of corruption, you should immediately add a bactericide to kill the bacteria. Reminder: In order to improve production efficiency, reduce maintenance costs, and achieve good economic benefits, the first time the cutting fluid protection measures should be selected. At present, there are many types of cutting fluid markets, different sources, and different quality and quality. It should be eliminated with high -quality brands with unknown and unknown and three -without quality. Try to choose manufacturers with genuine products and professional after -sales service guarantee.
