Why Does Mirror Spark Oil Change Color? Is it different from regular spark oil?
April 14, 2023
There is a difference between mirror spark oil and regular spark oil Spark oil is divided into mirror surface spark oil and general spark oil. No matter which kind of engine oil is used, it is required to have a high brightness. The color of the oil is bright and clear, without foam and corrosion, so as to facilitate manual operation. In addition, it is also required that the flash point be above 110 degrees Celsius and have good insulation function to avoid safety damage. Mirror spark oil has a higher flash point compared to regular spark oil, which can provide higher safety and instant discharge capability during the machining process; The lower conductivity allows for better control of sparks and enhances the clarity of machining. The aromatic content is simply close to zero, almost achieving a tasteless effect, increasing the comfort and safety of use. Mirror surface spark oil and general spark oil can meet general machining requirements, but when there are higher precision and quality requirements, mirror surface spark oil needs to be used, and mirror surface spark oil is becoming more environmentally friendly. It is recommended to use both mirror surface spark oil. No matter what type of spark oil it is, it is necessary to operate it safely according to the requirements, and correctly use spark oil in order to improve processing power and ensure processing safety.
Reasons for discoloration of spark oil 1. Impurities such as dust were mixed in during use The use environment of spark oil is not enclosed. During use, impurities such as dust in the air and debris generated by spark plug operation can enter the spark oil, causing it to become black. 2. The temperature during use is too high, causing the oil to oxidize and form carbon deposits In the process of electric discharge machining, an arc is generated between the two electrodes, causing an instant increase in temperature. Therefore, during machining, we will completely immerse the parts that need to be machined into the spark oil, and the temperature increase generated by the work will accelerate the oxidation reaction of the oil, thereby making it black. 3. Mixed with water, emulsified with oil The moisture in the air will enter the oil and undergo emulsification reaction with the components in the oil, resulting in the oil turning white or yellow. How long does the spark oil change? According to the contact of the spark plug, the general platinum contact can be replaced after 60000 kilometers, while the regular contact can be replaced after 20000 kilometers. Secondly, it is recommended to replace it around once a year based on the amount and frequency of use.
How to choose spark oil? In summary, the six most important factors for purchasing spark oil are: 1. Oil viscosity should be below 2.0 2. The flash point should be above 110 degrees 3. Good insulation performance 4. Oil is not volatile 5. Require non-toxic and harmless 6. The color of the oil product requires clarity and high transparency
