Objective: to reduce friction and wear Typical compounds: sulfur, phosphorus, chlorine, lead and other compounds. Such as sulfurized olefins, chlorinated paraffins, ZDDP, borates, etc., they form an adsorption film or reaction film on the friction surface to protect the friction surface. Detergent...
The advanced anti-wear additives in Pennzoil Synthetics, like ZDDP or “zinc,” form a protective layer that is thinner than a strand of human hair, yet able to absorb impact at high pressure points inside your engine. This layer protects all of the parts of your engine from wear caused ...
ZDDP in motor oil. A letter to the editor is presented in response to the article "What's That Stuff?," by Steve Ritter.GussmanNeilChemical & Engineering News... Gussman,Neil - 《Chemical & Engineering News》 被引量: 0发表: 2006年 ...
Zinc dialkyldithiophosphate (ZDDP) is a common anti-wear agent. This type of additive literally reacts with the metal surface when the reaction energy (temperature) is high enough. The reaction layer provides sacrificial surface protection. As the loading and metallic contact increase, the strength...

FTIR is a quick and sophisticated method for determining several oil parameters including contamination from fuel, water, glycol and soot; oil degradation products like oxides, nitrates and sulfates; as well as the presence of additives such as zinc dialkyldithiophosphate (ZDDP) and phenols. The FTI...
