The use of graphene as an additive in motor oil

Because the domestic car culture is not mature enough, many people's car concept still stays in the car is very "precious", need to be careful "care" state, so created a lot of incorrect car concept, such as "high speed destroyed the machine", "early upgear saving fuel", "slow speed to save fuel" and so on.

In this environment, there are more and more maintenance "supplements" on the market, especially the wide variety of oil additives, and there are countless impostors! Today, let's tell you what an oil additive is.

At present, the popular oil additives on the market are generally divided into two categories - cleaning agents and anti-wear agents. Cleaners rarely run in the engine for a long time, and are only used as a thorough cleaning before changing the oil. But the anti-wear agent is not the same, it plays a very important role: for example, when we wash clothes, it is difficult to wash them with water only, but after using detergent, the clothes can be bright as new. For engine oil, base oil is equivalent to water, additives are equivalent to detergent, what is the lubrication and protection ability of an oil, to a large extent depends on the quality of additives.

Through what way to improve the lubrication ability, has been the focus of the major oil and additive manufacturers research, the current most mainstream anti-wear additives with active metals (such as zinc, molybdenum, etc.) with phosphorus and other oxidants to achieve the effect of "the friction surface of the broken gully filled", so as to achieve reduced resistance.

With the development of science and technology, especially the improvement of graphene technology in recent years, graphene additive technology has entered the field of lubricating oil. From a technical point of view, the lubrication principle of graphene is not exactly the same as the previous anti-wear additives - because the molecular particles of graphene are very small, it can produce a ball effect when friction between the cylinder wall and the piston, turning the sliding friction into rolling friction, and at the same time, it can smooth the uneven place on the cylinder wall like putty.

For example, with the action of graphene oil, it is as if we are pushing a large stone (piston) on the ground which is covered with balls and spilled oil. In this case, there is no ball for the reduction of friction can be said to be a world of difference. Does the complexity of the technology suddenly become clear in your mind?

The application of graphene as an anti-wear agent can make low-viscosity oil more popular, thereby helping cars be more energy efficient and environmentally friendly. But is technology that sounds so grand just out of our reach? Not necessarily

Recently, after a long period of research and development and testing, the graphene oil produced by a lubricant company in Beijing has begun to go on sale, which can reduce the coefficient of friction and high temperature resistance, and China's graphene technology is in the world's leading level, domestic graphene can meet the requirements.
