Type of diesel antiwear agent: diesel antiwear agent is an additive to improve the lubricity of diesel oil. The ideal antiwear additive is mainly composed of long chain linear molecules with polar oxygen and nitrogen. At present, the main additives to improve the lubricity of diesel oil are long chain carboxylic acids, esters, amides, ethers, alcohols and so on. It is characterized by hydroxyl, amine, organic carboxyl polar groups of the oily agents. Esters are the most promising components of clean diesel oil at home and abroad. Esters are dehydrated by organic acids and alcohols. It has the advantages of strong hydrolysis resistance, good detergency and dispersion, and high extreme pressure performance. Esters contain many kinds of oxygen atoms, such as carbonyl oxygen and alcohol oxygen, which can form a thick oil film between friction and each other, which is very important to lubricate effect, and effectively protects the metal surface from being oxidized and corroded. Non-toxic and harmless, it is an environmental-friendly anti-wear agent for hydrogenated diesel oil.
Product advantages: polyglycerol polycastor oil ester is the most advanced and most environmentally friendly diesel antiwear additive with high molecular weight (1200-1400), good oil solubility, easy dispersion, difficult emulsification, strong water resistance, good cleanliness and dispersion, and high extreme pressure performance. Lubricating effects and mottled lubricating film effects have caught up with similar products in the United States. The added amount of this product is 1/3 of low freezing point fatty acid, the added amount is 80-200 mg / kg, the diameter of friction spot is less than 200-300 μ m.
