Problems solved by technology

[0003] However, due to the active chemical properties of magnesium alloys, it brings great difficulty to the processing. During the processing, a large amount of magnesium ions will dissolve into the cutting fluid, causing the magnesium hardness of the cutting fluid to rise rapidly, resulting in the stratification of the cutting fluid and making it unusable.
At the same time, the corrosion resistance of magnesium alloy is poor, and it is easy to cause corrosion and discoloration during processing, and it is also easy to generate hydrogen gas, which affects the safety of operation and processing.
However, the current conventional magnesium alloy cutting fluids have been unable to adapt to magnesium alloys due to the common problems of poor resistance to magnesium hard water, short service life, poor magnesium corrosion resistance, large hydrogen generation, and poor operating safety. Therefore, it is necessary to develop a water-soluble cutting fluid with excellent performance that meets the harsh requirements of magnesium alloy processing.

Description

Technical field: [0001] The invention relates to a water-soluble cutting fluid. Background technique: [0002] Magnesium alloy has low density (about 1.8g / cm3, about 2 / 3 of aluminum, 1 / 4 of iron), high specific strength, good heat dissipation, strong anti-electromagnetic interference, large elastic modulus, and good shock absorption And other advantages, so it has a wide range of applications in the fields of aviation, aerospace, automobile industry, etc., in order to achieve the purpose of lightweight. [0003] However, due to the active chemical properties of magnesium alloys, it brings great difficulty to the processing. During the processing, a large amount of magnesium ions will dissolve into the cutting fluid, causing the magnesium hardness of the cutting fluid to rise rapidly, resulting in the stratification of the cutting fluid and making it unusable. . At the same time, magnesium alloys have poor corrosion resistance, and are prone to corrosion and discoloration d...
