Be well known that at present, when engine operation, there is mechanical friction in moving component each other, and this friction will cause fortuneDynamic component weares and teares and produces corresponding metallic particles and carbon distribution impurity, metallic particles and carbon distribution impurity be entrained in machine oil and along withOil circulation is brought wearing and tearing to miscellaneous part, and particularly wearing and tearing can produce the larger metallic particles of some particle diameters, these larger grainsThe metallic particles in footpath can further produce more serious wearing and tearing to miscellaneous part, like this for a long time, will have a strong impact on the property of engineEnergy and service life. Meanwhile, because metallic particles and carbon distribution impurity are entrained in machine oil, therefore, and after a period of time, the one-tenth of machine oilPoint and molecular structure change, and purity viscosity and greasy property obviously decline, thus it is old to accelerate the wearing and tearing of engine componentsChange, shorten the service life of machine oil and engine, so the metallic particles of greater particle size is to have for engine and machine oilEvil, be called again poisonous metal particle, must remove.
Be to use magnetic to mix machine oil for a solution of the problems referred to above, its principle is in machine oil, to add necessarilySchedule of proportion surface-active agent and magnetic particle, under the magnetic action of magnet particulate, machine oil sticks to parts by magnetic particleOn surface and form lubricating layer, thereby reduce the wear and aging of parts, extend machine oil service life, improve the dynamic property of engineCan, still, magnetic mixer oil is expensive, and will change and destroy together with oil filter after using a period of time.And regular engine oil is under the working environment of the high rotating speed of vehicle motor and high-temperature, its viscosity can be along with the rising of mechanical temperatureAnd reduce, and finally run off from surface of the work, reduce the lubricant effect of parts.
It should be noted that in the metallic particles producing in the moving component wearing and tearing of engine, except larger the having of particle diameterOutside evil metallic particles, also contain the metal particle that some particle diameters are relatively little, these metal particles can make to adhere to through magnetizationThe surface that machine oil in its surface is together effectively adsorbed on engine parts forms lubricating layer, makes the surface of mechanical part damagePlay repair. Therefore, these metal particles need to be retained in machine oil and can be used afterwards by magnetization,Be called again useful metal particle.
