Introduction
The reasons for the black and turbid waste lubricating oil are as follows:
The most common reason for the blackening and turbidity of lubricating oil is caused by these three kinds of substances: carbon deposition, air bubbles and water (liquid water, water vapor). In addition, there are also some reasons for the turbidity of lubricating oil.
1. There is water in the lubricating oil: if less water is mixed in, the oil will become turbid and look gray, which is similar to the taffy color of grayish yellow. If there is more water, the lubricating oil will turn into milk like white emulsion. In this case, find out the source of water immediately.
2. Incomplete dissolution of additives: there are additives in lubricating oil generally. In some cases, additives will precipitate, which is a normal phenomenon. For example, at low temperature, some oils will have this problem. However, the turbidity caused by this situation should be only a little turbidity, sometimes a little precipitation, is the precipitated additive.
3. Decomposition products of additives: in normal use, additives of lubricating oil will also decompose to produce some white flocculent substances. Since it is produced by normal use, this change of lubricating oil should occur gradually with use.
4. The reason why the black additive is added into the process environment and the lubricating oil turns black is mainly based on the production process and production environment. For example, the rubber tire industry produces tires. In the production process, rubber particles are used for pressing. During the pressing process, the rubber particles will be mixed into the lubricating oil products to form black.
How to solve the problem of black and turbid lubricating oil for you
Features of waste lubricating oil decolorizing vacuum purifier: waste lubricating oil decolorizing vacuum purifier is widely used in engine oil, gear oil (open and closed), hydraulic oil, forming oil, gutter oil, rail oil, compressor oil and vacuum pump oil in petroleum, chemical industry, cement, metallurgy, mine, electric power, ship, machinery, military industry, rubber and plastics, instrument, transportation, building materials, papermaking and other industries , full loss system oil, axle oil, pneumatic tool oil, guide rail oil, bearing oil, cylinder oil, conduction oil, transformer insulating oil (mineral oil, synthetic oil) and other industrial waste oil regeneration.
1. The waste lubricating oil decolorizing oil purifier series is the upgrading product of all oil filters of our company. It has many unique technologies. This machine fills in the blank that the oil filter cannot decolorize. After treatment, it can completely reduce the waste oil to a new oil color, marking the new era of waste oil purification has arrived. In the oil filter industry, this equipment technology is more than ten years ahead of the same industry.
2. According to the characteristics of petroleum, the waste lubricating oil decolorizing oil purifier adopts the unique global low-temperature microfiltration purification technology, that is, the pure physical flocculation and bridge technology is used, without acid-base process, to completely remove all the suspensions or deposits that are not soluble in gasoline and benzene, so that the molecular chain and oil film of the oil can be reconstituted and linked, and the physical and chemical indexes of the oil can be made without destroying the original physical indexes of the oil Standards and cleanliness are restored to national standards, so as to achieve the goal of waste oil reuse.
3. The waste lubricating oil decolorizing oil purifier has no filter element and filter paper. It adopts the global advanced technology - magnetic field filtration technology and automatic operation, which reduces the labor intensity, saves the cost and gets rid of the decades' history of using filter element in vacuum oil purifier. At the same time, it also ended the embarrassing situation that the vacuum oil filter could not filter the oxidized impurities, resulting in the filtered oil not reaching the national standard.
