Identification of deterioration During the use of lubricating oil, some bulk oils deteriorate due to improper storage. Therefore, to master more of the identification method of deteriorating lubricating oil, it will provide more protection for safe oil. First, the oil flow observation method: take two measuring cups, one of which contains the lubricating oil to [...]
(1) Physical purification method This method mainly includes sedimentation, filtration, centrifugation and water washing. In the specific regeneration treatment, one or several types of unit operations may be selected as the purification treatment of the waste oil according to the degree of deterioration of the waste oil, equipment conditions, and the like. This method is [...]
We all know that there are SJ, SL, SM, and SN grades in the market, but how do we distinguish these levels? We interviewed experts in the field of lubricants, let's continue with the topic that we didn't finish last week. Candy Zhang: What is the difference between the antioxidant properties of SM and SL? [...]
With the development of society, cars are becoming more and more popular in people's daily life. Cars have become an indispensable means of transportation, and the maintenance issues of cars have become a major topic of concern for car owners.So naturally, how to choose the oil is also the first problem. We all know that [...]
The waste oil is sprayed on the road which is easy to dust, and the dust is adhered by the adhesive action, which is dustproof and is also a treatment method of the waste lubricating oil. In the United States, a significant portion of the recovered waste lubricating oil is used for this purpose. However, [...]
Lubricating oils generally consist of two parts, base oil and additive. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, and give some new properties. It is an important part of lubricating oil. Lubricating oil [...]
At present, domestic waste oil regeneration catalyst presents two situations: one is gas phase catalyst, which is filled with strip catalyst in the gas pipeline above the regeneration furnace. The newly produced catalyst is effective in a week and can make the refined oil light in color. But after a week, it will be poisoned [...]
1 Waste oil recovery The sources of used oil are as follows: (waste oil, diesel, transformer oil, heavy oil, lubricating oil, industrial heavy oil, etc.) 1) Waste oil when the equipment is replaced with lubricating oil. Whether it is a regular oil change or a quality change, the equipment is replaced with waste. Oil is [...]
1.Being contaminated by foreign impurities Oil is most susceptible to soiling by various mechanical impurities during system use. These impurities are metal scraps, dust, sand, fibrous matter, and the like. This is because the metal powder that has been rubbed off on the friction mechanism falls into the oil, or the dust and sand are [...]
Lubricants are gradually contaminated with moisture and mechanical impurities during use. Even without the presence of metals and other catalysts, pure liquid water promotes oxidation of the oil. However, in actual use, the lubricant is always in contact with the metal. After water is contained in the oil, the oxidation of the oil is actually [...]
