Development of bioproof lubricant compositions on the basis of regenerated oils
In the Institute of Chemistry of Additives of ANAS the technological scheme of the regeneration of waste oil «Mysella-40» using local natural adsorbent - bentonites was developed. The study of various values of functional additives, based on the products of regeneration, new types of lubricating compositions of «Mysella-40» type were made, which by their exploitation properties fit commodity oil. The article also presents the results of the study the biological stability of the waste and regenerated lubricating oil «Mysella-40» which is intended for high-speed engines with spark ignition, biocides are designed to protect the oil from microbiological defeat. It is found that the use of biocides in the recommended concentrations provide complete and long lasting protection of oil from fungi and bacteria, and at the same time does not adversely influence the basic performance characteristics of the lubricating oil.
