一)清净分散剂
(1) detergent dispersant
清净分散剂被用来中和油品氧化后产生的酸性化合物,防止酸性化合物进一步氧化,并能吸收氧化物的颗粒,使之分散在油中。因此就可以抑制漆膜的生成,将已生成的积炭和漆状物从金属表面洗涤下来,不至于结垢或沉积在金属表面上。这类清净分散剂是一种抗氧化、抗腐蚀、抗磨多效能添加剂,主要应用在内燃机油中,其消耗量目前占全部润滑油添加剂50%以上。
The detergent dispersant is used to neutralize the acidic compounds produced by the oxidation of the oil products, which can prevent the acid compounds from further oxidation, and can absorb the particles of the oxide, so that it can be dispersed in the oil. So it is possible to inhibit the film formation, has produced the coke and paint from the metal surface washing down, as regards the scaling or deposition on the surface of the metal. This kind of detergent dispersant is a kind of antioxidant, anti corrosion and anti wear additive. It is mainly used in diesel oil, and its consumption accounts for more than 50% of all the lubricating oil additives.
(二)抗氧化添加剂
(two) antioxidant additives
抗氧化添加剂可防止油料氧化变质。抗氧剂加入润滑油中,可以减少油料吸取的氧气量,从而使润滑油与氧作用发生酸性化合物的生成率大大降低,阻止氧化反应,延长了油料的使用寿命。抗氧剂多用在中低温度下运行的润滑油,如变压器油、汽轮机油、液压油、仪表油等。
Antioxidant additives to prevent oil oxidation. Antioxidant is added in lubricating oil, can reduce the amount of oxygen absorb oil, so that the role of lubricating oil with oxygen of acidic compounds generation rate is greatly reduced, prevent the oxidation reaction, and prolongs the service life of the oil. Use of antioxidant lubricating oil run in low temperature, such as transformer oil, turbine oil, hydraulic oil, oil and other instruments.
(三)增黏剂
(three) viscosity increasing agent
增黏剂加入油中能影响润滑油的黏度。当温度升高时,增黏剂的分子便“舒展”开来,防止了润滑油的黏度降低。在温度低时,增黏剂溶解度减小,分子又开始“蜷缩”成紧密的小团,所以对黏度的影响小,不至于润滑油在低温时黏度过于变大。
The viscosity of lubricating oil can be influenced by adding viscosity agent into oil. When the temperature is raised, the molecules of the adhesive will be "stretched" to prevent the viscosity of the lubricant. When the temperature is low, the viscosity reducing agent solubility decreases, and the molecule begins to "curl" into a tight small group, so the viscosity is small, and the viscosity is too large when the temperature is low.
(四)油性添加剂
(four) oily additives
油性添加剂是用来改善油品在边界摩擦时的润滑性能,保持小的磨损和低的摩擦系效。这类添加剂都是极性分子,定向地吸附在金属摩擦表面,形成牢固的油膜。这类油品在承受较高的压力时油膜不易破坏,加强了边界润滑的效果。油性添加剂一般在边界润滑时起作用,但不能起极压润滑作用。
Oil additive is used to improve the lubrication performance of the oil in the boundary friction, keep the minimum wear and low friction coefficient effect. These additives are polar molecules, which are adsorbed on the surface of the metal friction, and form a strong oil film. The oil film is not easy to damage when the oil is subjected to high pressure, and the effect of boundary lubrication is enhanced. Oily additives generally play a role in boundary lubrication, but can not play the role of extreme pressure lubrication.
(五)极压添加剂
(five) extreme pressure additive
极压添加剂主要是含硫、磷、氯的有机极性化合物,这类化合物在常温时不起润滑的作用,在高压高温下能与弹簧机械金属表面形成比较牢固的化合物膜。它比金属的熔点低,当弹簧机表面因摩擦而温度升高时,这层化合物膜就熔化了,生成光滑的表面,能减少摩擦和磨损。此外,常见的添加剂还有防锈添加剂、降凝剂、抗泡剂、抗氧抗腐添加剂等。
Extreme pressure additive is mainly sulfur, phosphorus, chlorine organic polar compounds. These compounds at room temperature without lubrication and under the high temperature and high pressure can form relatively strong compound film with the mechanical spring metal surface. It is lower than the melting point of the metal, when the spring machine surface due to friction and temperature rise, this layer of compound film will melt, and generate a smooth surface, can reduce friction and wear. In addition, the common additives are anti rust additives, reducing agent, anti foam agent, anti oxidant, anti - corrosive additives, etc..
