REGULARITIES OF CHANGING THE WORK OF ADHESION TO THE SURFACE OF A SOLUTIONOF SULFONATE ADDITIVE IN BASE OIL NS-4DURING ULTRASONIC TREATMENT IN THE PRESENCE OF SUCCINIMIDE ADDITIVES

The article presents the results of a study of the effect of ultrasonic treatment of a highly alkaline sulfonate additive on the surface tension and wetting angles of a steel plate with a solution of the sulfonate additive in the base hydrocracking oil NS-4 in the presence of succinimide additives of different molecular weights. The regularities of changes in the work of adhesion to a steel plate of a solution of the sulfonate additive in the base oil during ultrasonic treatment without and in the presence of succinimide additives are revealed. It is shown that ultrasonic treatment contributes to the modification of interphase interactions, and the introduction of succinimide additives has a stabilizing effect on the properties of the resulting dispersed system. The obtained results allow optimizing the composition of additive packages to improve the anticorrosive properties of lubricants and can find practical application in the development of new additive packages.
