There are many ways to distinguish between good and bad lubricants, there are four more common and practical methods, oil flow observation method: Take two measuring cups, one containing the oil to be checked, the other empty on the desktop, the The measuring cup filled with oil is lifted 30 to 40 centimeters away from the table and tilted so that the oil slowly flows into the empty glass and observes its flow. Good quality lubricating oil flow slender, uniform, continuous; if the flow suddenly flicker, sometimes a large stream, then the oil has been deterioration. Hand twist method: twist the oil between the thumb and index finger repeated grinding, the better the oil lubrication, less wear debris, no friction; if there is sand between the fingers like a larger friction, it shows Impurities within the oil, can no longer be used, should be replaced with new oil. Light method: In fine weather, use a screwdriver lifted the oil, and 45 degrees angle with the horizontal, the control of sunlight, observation of oil droplets. Light, you can clearly see the wear debris in the lubricant is good; if the wear debris too much, it should be replaced. Drop marks method: Take a clean white filter paper, the number of drops of oil, until the oil leakage, if the surface of a black powder, feel a sense of obstruction by hand, then there are many impurities in the oil, a good oil No powder, dry and smooth by hand, traces yellow.
Lubricant additives according to the functional points are mainly anti-oxidants, anti-wear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, corrosion inhibitors, flow point improvers, viscosity Exponential enhancer and other types. The additives sold in the market are generally more than a single additive compound, the difference is that the composition of a single additive and composite additives within the proportion of several single additive different only. In recent decades, imported cars and the introduction of technology to produce a substantial increase in the production of motor vehicles, the quality requirements of the oil is also getting higher and higher, the use of single-ingredient raw material blending technology not only in the process of trouble, but also in formula evaluation The difficulty is also great, most lubricants blending plant is difficult to do. Therefore, some manufacturers produce composite additives on the basis of gantry evaluation. The compounding agent has many functions required by the refined oil. As long as the appropriate dosage is added to the specified basic oil, a certain quality grade oil can be produced Product The compounding agent as raw material has the advantages of simple production process, convenient operation, short production cycle and good economy.
