Additive action and mechanism
Use, then you must use extreme pressure agent. At the beginning of the extreme pressure agent and friction metal surface solid interface for the friction should be generated, to prevent the metal friction surface contact protection lubricating film. Organic polar molecules with double bond structures, such as the chemical reaction mechanism of alpha-olefins, are less affected by the pressure and the temperature plays a major role, doubling the reaction rate for each 10 ° C rise, but under the action of friction May reach several hundred times to several hundred times.
When the heavy or heavy impact load is generated when the local high temperature close to 200 ℃ or more, the oil chemical adsorption film will be lost
Oil additives to improve and improve the lubricating performance of lubricating oil can be divided into two parts: oiliness additive and EP-Antiwear (China). Because of their differences in applicability and mechanism of action, It is sometimes difficult to distinguish between the two. Therefore, in the Western countries, the extreme pressure agent, anti-wear agent and oily agent collectively referred to as load additives (Load-Carrying additives).
