  Water is the most common contaminant found in lubricating oils. It is also one of the most damaging to bearings and other lubricated components. It causes corrosion to metal surfaces, lubricant degradation, and poor lubrication. Water can be present in three forms of dissolved, emulsified, and free in lubricating by:   Physical Properties of Fats and Oils. Contrary to what you might expect, pure fats and oils are colorless, odorless, and tasteless. The characteristic colors, odors, and flavors that we associate with some of them are imparted by foreign substances that are .

Various other physical properties may be measured, most of them relating to specialized lubricant applications. Some of the more important measurements are: density. Important, because oils may be formulated by weight, but measured by volume. demulsification. Ability of oil and water to separate. foam characteristicsCited by: 5.

When soap is made from the sodium salts of the acids of cheap oils or fats, the resulting soap is hard. These soaps contain free alkalis and are mainly used as washing bars for laundry. When soap is prepared from the potassium salts of the acids of good grade oils and fat, it results in soft soap. These soaps do not contain free alkalis.

Physical Properties of Lubricants Valvoline Technical Services Page 1 Following are the important properties of a lubricant. Density Density is fundamental physical property of oil. It is the mass of liquid per unit volume. It is measured at specific temperature by Hydrometer or Automatic Density Size: KB.

The automotive lubricants arena has undergone significant changessince the first edition of this book was published in Environmental concerns, particularly reagarding improvement of arquality have been important in recent years, Reduced emmissions aredirectly related to changes in lubricant specifications andquality, and the second edition of the Automotive LubricantsReference Book 4/5(4).

Lubricating oils can oxidize when exposed to air, particularly at elevated temperatures, and this has a very strong influence on the life of the oil.

The rate of oxidation depends on the degree of oil refinement, temperature, presence of metal catalysts and operating [email protected]{osti_, title = {Physical and chemical properties of industrial mineral oils affecting lubrication}, author = {Godfrey, D.

Liquid lubricants, generally referred to as oils, share the properties of all liquids, are able to flow, and take the shape of their containers.

Lubricating oils, like other types of lubricants, are tested for many different properties that determine how they will function over a range of conditions and environments.

The present paper describes a part of an introductory examination concerning the improvement of tribological properties of base oils (used for lubricating as well as cutting oils compounding.

These tests were set up such that the lubricating oil was degraded in the ring pack before returning to the sump, where it was sampled and chemical and rheological analysis undertaken.

Lubricating oils should be clear and bright and free from water, sediment and other impurities. A water content of 0,01% to 0,02% will make oils cloudy. Only a very small amount of water will actually dissolve in oil, the remainder being insoluble and making the oil cloudy. A Study of Enhancement of the Properties of Lubricant Oil Ahmed N.

The Effect of Base Oils on Thickening and Physical Properties of Lubricating Greases This paper examines the effects of naphthenic, paraffinic, and synthetic (polyalphaolefin or PAO) base oils on the thickening capabilities of lithium hydroxystearate (Li HSA), lithium complex (Li complex), aluminum complex (Al complex), clay base,File Size: 1MB.

The product was to be settled, dechlorinated, purified with active clay (3 hours at ° C, 5% by weight of clay), filtered, and topped. A light lubricating oil and an aircraft lubricating oil were to be obtained from the product.

Chemical and physical properties of product produced in small scale pilot plant tests are shown in Table 1. Base oils can have different physical or chemical properties or perform differently in engine testing.

In order to accommodate the need for flexibility during engine oil manufacture, base oil interchangeability guidelines have been developed to ensure that the performance of engine oil products is not adversely affected when different base oils.

From a survey of available data on the density of fluid lubricants as a function of pressure and temperature, the following empirical equation has been derived: ρ=ρ0(1+ap−bp2)t. ρ is the density at a given pressure (gage) p and temperature t; ρ0 is the corresponding density at atmospheric pressure.

The constants a and b are evaluated over a temperature range extending from 20° to °F Cited by: Abstract. The physical and chemical properties of mineral oils that affect lubrication are reviewed.

Recognition of these properties is useful for designing lubrication systems, diagnostics, friction and wear problems, and selecting appropriate test methods.
