For last two decades, with

With economic development and technology continuous improvement, automobile design of the engine to development of the miniaturized, powerful, high speed and made higher demands to thermal stability of additives of lubricating oil carry out their functions under conditions of environment of the high temperature accompanied by factors of environment, and the government declared instructions which limit use of certain additives. For last two decades, with understanding of physical and chemical properties of pine forest of an element, scientists found that the entered powder of pine forest to oil lubricant additives can improve and increase protivoiznosny properties and thermal stability, additives of pine forest can solve better the additives containing a harmful component and a part of metal for some limited and reduced number of oil function, pine forest of an element gives oil energy saving and environmental protection. Part of the main business of additives of production at the international level, the dispergator and protivoiznosny agents containing pine forest and a set harmless to environment, the energy saving changed products in the 1980th, the 1990th developed the detergents containing pine forest, containing pine forest, do a pine forest element widely used in the field of additives of lubricants. China is developed now containing pine forest a dispergator and extreme pressure containing pine forest and protivoiznosny agents and so on. The element of pine forest is usually entered by means of boric acid and alkaline compound cumulative molecules, thus, boric acid, became one of important raw materials for additives of lubricants.
