What are the characteristics of Span-80 emulsifier? How is it used in metal working fluids? What are the advantages?
Span-80 emulsifier, chemically known as sorbitan monooleate or anhydrous sorbitan monooleate, is an amber to brown oily liquid with unique chemical properties. Its melting point is moderate, the flash point is high, the smell of fat is emitted, it is insoluble in water but can be easily dissolved in hot oil and organic solvents, showing the characteristics of advanced oil-wet emulsifier. In addition, it also has the characteristics of acid, alkali and hard water resistance, so that it can maintain a stable emulsification effect in a variety of environments.
Span-80 emulsifiers are widely and deeply used in metal working fluids. First of all, it is often used as a co-solvent of anti-rust agents, and benzotriazole, barium petroleum iodate, petroleum grease oxide and other anti-rust agents used together, can effectively improve the anti-rust effect, extend the service life of metal products. Secondly, in the metal cutting fluid, coolant and other processing fluids, pan 80 emulsifier can significantly improve the stability and lubricity of the liquid, reduce the friction and wear of the metal surface, and improve the processing quality and efficiency. In addition, it also has excellent dispersion properties, which can evenly disperse the solid particles in the processing fluid to prevent clogging and wear.
Span-80 emulsifier has obvious advantages in the application of metal working fluids. First of all, its excellent emulsification performance can effectively mix water and oil to form a stable emulsion, improving the stability and service life of the processing fluid. Secondly, the wide range of application of Pan 80 emulsifiers enables it to respond to a variety of metal processing needs, whether cutting, grinding or cooling, can play a good role. Moreover, its strong stability ensures that the processing fluid is not easy to stratification and precipitation during long-term use, reducing maintenance costs. Finally, the low foaming property of the Span-80 emulsifier makes the processing fluid less foam during use, reducing the influence of foam on the processing process and improving the work efficiency.
It is worth mentioning that Pan 80 emulsifier also has multiple functions such as solubilization, wetting, thickening, etc. These functions also play an important role in metal processing fluids. The solubilization function can help the processing fluid dissolve various additives better and improve the comprehensive performance of the processing fluid. The wetting function helps the processing fluid to better wet the metal surface and improve the processing quality. The thickening function can make the processing fluid have better adhesion and adhesion, and reduce the loss of the processing fluid.
In addition, Pan 80 emulsifier also has environmental protection, its biodegradability is good, the impact on the environment is small, in line with the development trend of modern green manufacturing. In the metal processing process, the use of Span-80 emulsifier processing fluid can effectively reduce the waste liquid generation and treatment costs, reduce the pressure on the environment.
In general, Span-80 emulsifiers play an important role in metal working fluids with their unique chemical properties and a wide range of applications. Its excellent emulsification performance, wide application range, strong stability and low foam characteristics make it have significant advantages in the metal processing process. With the continuous progress of science and technology and the improvement of environmental awareness, the application of SPan-80 emulsifiers in the field of metal processing will be more extensive and in-depth, providing strong support for the development of metal processing industry.
