What is the difference between barium petroleum sulfonate and sodium petroleum sulfonate in the application of antirust oil?Both products are sulfonate rust inhibitors, in generalBarium petroleum sulfonateIt's better. Sodium petroleum sulfonate is soluble in oil and water, and the configured oil is emulsified in water, so it is inferior to barium petroleum sulfonate in terms of damp heat resistance and salt spray resistance.
Sodium petroleum sulfonate T702 is often used in the preparation of emulsified oils.
Sodium petroleum sulfonate(T702) has a good susceptibility to microemulsions, and the anti-rust effect is very obvious when added in an appropriate amount, and T702 is also a good surfactant as an oil-soluble corrosion inhibitor, which can be better dispersed in the system, thereby reducing the accumulation degree of the aqueous phase and playing a good roleAnti-rust effect.
Barium petroleum sulfonate T701 is divided into liquid and solid, and barium petroleum sulfonate is the product obtained from petroleum lubricating oil fraction by sulfonation and alcohol water extraction, and is prepared by barium salt saponification and then refining, which is used as an antirust additive in anti-rust grease. Liquid petroleum barium sulfonate is more convenient in the process of use, no longer disturbed by high temperature weather, easier to store, and eliminates the procedure of high temperature melting in the use process. Barium petroleum sulfonate has excellent resistance to moisture, salt spray, salt water and water displacement, and has excellent anti-rust performance for ferrous metals and non-ferrous metals.
Barium petroleum sulfonate T701 is suitable for use as a rust inhibitor in anti-rust grease, such as the preparation of replacement anti-rust oil, inter-process anti-rust oil, sealing oil, and lubrication anti-rust dual-purpose oil and antirust grease.
