Clean dispersant is mainly used for internal combustion engine oil. It is the main agent of internal combustion engine oil and the most used additive in lubricating oil. It is mostly surfactant, which is easy to emulsify and foam oil. During the working process of the engine, the high temperature parts, such as the combustion chamber, the piston ring area, and the piston-cylinder lubricating oil, are subjected to high temperature and harmful gases, and the hydrocarbons will decompose and polymerize to form precipitates such as paint film and carbon deposit. The object is attached to the working surface of the engine, which is caused by overheating of the engine part, sticking of the ring, pre-ignition of the surface, etc., causing power loss and piston burning. At medium temperature parts such as crankcases, valve chambers and other water vapours such as water vapor, the mixing of soot and lubricating oil metamorphism will produce sludge, blocking the oil circuit and the filter screen. The above also makes the lubricating oil thicker, thinner, faster and the like. The main function of the dispersing agent is to reduce the high temperature deposits generated by the internal combustion engine oil, and the ten piston zone is kept clean. The action of the dispersant can reduce the formation of sludge, so that the sludge formed by the dispersion cannot be adsorbed to each other and the large particles are suspended in the oil to cause the oil passage and the screen to be blocked. In general, the detergents and dispersants in the formulation of internal combustion engine oils are used in combination, and their functions also partially overlap, so they are generally referred to as detergent dispersants.
Most of the detergents are organic salts of alkali metals (calcium, barium), such as sulfonates, salicylates, alkylphenolates, etc., and some have excess calcium carbonate, all have a high total base number, and have good medium And the performance can neutralize the organic acid oxidized in the use of lubricating oil and the acidic sulfur oxide formed by the combustion of sulfur in the sulfur-containing diesel engine oil, thereby reducing the harm of these acidic substances to the internal combustion engine. The dispersant is mainly a succinimide compound, which acts to disperse and suspend the sediment.
The upgrade of the quality grade of the gas turbine is upgraded, and the upgrade of the grade is directly proportional to the increase of the total additive addition.
