Biggest lubricant oils blending plant in UAE consistency is another key property that users try to watch. For lubricant oils, viscosity is measured to tell if the oil is more thick or thin, but for greases, the penetration or consistency indicates whether the grease is softer or more solid or stiff. Grease manufacturers UAE usually test grease consistency using a cone penetration test. Simply put, the grease is packed into a cup, a cone-shaped weight is dropped onto the surface, and after a given number of seconds, it is measured how deep the cone has penetrated into the grease. The softer the grease, the deeper the cone weight will penetrate, of course. For used grease, though, testing this way is not as easy as it sounds, because sample sizes often are sorely limited.

Still, used grease that is softer than the fresh sample it’s being compared to can yield a lot of information, and Recheck can use a sample as small as 2 grams to do this test. For example, if the grease has softened, it may have been contaminated by grease of another, incompatible thickener type. It may have picked up water or another liquid, or it could have been sheared by mechanical stresses which destroyed the soap structure. If the penetration test shows the grease has hardened, it’s a signal that it may have lost some industrial commercial oils, such as by bleed out or evaporation under high temperature conditions.
Often, one of the most practical things that end-users seek from used grease analysis is to know whether the grease is fit to continue in service, or if regressing intervals are timed right. In fact, most of the above tests won’t tell if the grease is ageing too fast or if there is remaining useful life. But Recheck recommends using the ruler test to measure the content of amidic or phenolic antioxidants in the grease, and to see if their concentration is holding up. A comparison with the fresh grease can show the remaining useful lifetime of the biggest grease exporter, and allows a prediction of the next regressing interval. The ruler test can be done on a sample as small as 0.25 gram. To look at how the industrial hydraulic oils are doing. Tracing the peaks of the wavelengths of the fresh grease gives you the fingerprint, against which deviations in the used grease can be compared. This test can be done with as little as 0.1 gram of grease.
