Development of the composition and technology for obtaining a synthetic component of the basis of hydraulic oils for special equipment

Abstract

The rapid development of technology, the creation of promising products with characteristics corresponding to or exceeding the characteristics of the best world analogues, dictate the need to create a new level of quality oils – synthetic. The advantages of synthetic-based oils are excellent viscosity-temperature characteristics, good low-temperature fluidity, high anticorrosive properties, as well as increased thermal-oxidative stability, compatibility with materials. Since synthetic oils are chemically stable, they retain their original characteristics longer under adverse operating conditions. Other advantages of synthetic oils include increased resistance to shear deformations (due to the uniformity of the structure), high dispersing ability, fire resistance, chemical inertia and non-toxicity. It is also important that the synthetic base requires the introduction of a minimum amount of thickening additives. In addition, their resource significantly exceeds the resource of petroleum oils of a similar purpose. Among the numerous lubricants, a special place is given to low-viscosity hydraulic oils used in autonomous hydraulic drives of special equipment. The use of a basic synthetic base makes it possible to increase the guarantees of the shelf life and operation of hydraulic oil in products and ensure a quality preservation resource for 20 years or more.
