  柴油抗磨剂产品意义

  Significance of diesel antiwear agent products保护环境,降低汽车尾气对危害,提高柴油的品质,柴油的低硫化越来越受到世界各国的普遍关注,我国的柴油标准自2011年7月1日起执行GB19147-2009车用柴油标准,硫含量要求小于0.035%,对硫含量提出了较严格的要求。柴油在发动机中既作为燃料有作为输油泵的润滑剂,但是通过加氢脱硫等精制手段降低硫含量的同时,也降低了柴油的天然润滑性,造成使用低硫柴油的发动机易磨损和损坏,缩短 发动机的寿命,严重时可能引起油泵泄漏。因此柴油润滑性改进剂-柴油抗磨剂作为有效提高柴油润滑性能的手段,将到广泛的应用。

  To protect the environment, reduce the harm of automobile exhaust and improve the quality of diesel oil, the low sulfuration of diesel oil has attracted more and more attention all over the world. Since July 1, 2011, China's diesel oil standard has implemented gb19147-2009 standard for automobile diesel oil. The sulfur content is required to be less than 0.035%, which puts forward stricter requirements for sulfur content. Diesel oil is not only used as fuel in the engine, but also as the lubricant of the oil delivery pump. However, it can reduce the sulfur content by hydrodesulfurization and other refining means, but also reduce the natural lubricity of diesel oil, which makes the engine using low sulfur diesel oil easy to wear and damage, shortens the life of the engine, and may cause oil pump leakage in serious cases. Therefore, diesel lubricity improver - Diesel antiwear agent, as an effective means to improve diesel lubricity, will be widely used.

  以前,由于对柴油的精制要求不高,柴油中含有较多的杂环芳烃硫化物或氮化物、多环芳烃的硫化物或氮化物,而这些物质是天然的抗磨组分。因此,没有出现柴油的润滑性问题。近年来,随着环保对柴油质量提出的要求越来越高,柴油中硫含量受到了严格的控制,柴油的润滑性问题逐渐暴露出来。大多数低硫柴油润滑性很差,硫含量小于500μg/g的柴油就可以会使发动机产生磨损,而欧Ⅳ标准规定柴油的硫含量不能大于50μg/g。柴油低硫化将成为未来车用柴油发展的必然趋势,但随之引起的低硫或超低硫柴油的润滑性问题必然越来越严重。

  In the past, due to the low refining requirements for diesel oil, there were more heterocyclic aromatic sulfide or nitride, polycyclic aromatic sulfide or nitride in diesel oil, and these substances were natural anti-wear components. Therefore, there is no lubricity problem of diesel oil. In recent years, with the increasing requirements of environmental protection for diesel quality, the sulfur content in diesel has been strictly controlled, and the lubricity of diesel gradually exposed. The lubricity of most low sulfur diesel is very poor. If the sulfur content is less than 500 μ g / g, the engine will wear. However, according to Euro IV standard, the sulfur content of diesel cannot be more than 50 μ g / g. Low sulfur diesel will become the inevitable trend of the development of automotive diesel in the future, but the lubricity of low sulfur or ultra-low sulfur diesel will become more and more serious.

  柴油抗磨剂作用原理

  Action principle of diesel antiwear agent润滑性改进剂是具有一定极性和化学反应活性的化合物。当温度较缓和时,吸附为物理吸附;在温度很高时,极性基团与表面活性金属发生化学反应,形成金属有机化合物,使润滑膜不发生破裂,起到提高润滑性能的作用。

  Lubricity improver is a compound with certain polarity and chemical reaction activity. When the temperature is moderate, the adsorption is physical adsorption; when the temperature is very high, the polar group reacts with the surface active metal to form organometallic compounds, so that the lubricating film does not break, which plays a role in improving the lubricating performance.
