The structure of zinc dithiophosphate The R group dictates whether it is an alky or aryl dithiophosphate In order to understand the lubrication properties of ZDDP one needs not only to determine its lubrication performance but also be able to explain its behaviour at a fundamental level Both objectives involve a wide range of investigations
2 Zinc Dithiophosphate Powder Description The main use of Zinc Dithiophosphate Powder is in anti wear additives to lubricants such as greases gear oils and motor oils which often contain less than 1% of this has been reported that zinc and phosphorus
Sliding experiments were performed with various blends consisting of base oil zinc dialkyl dithiophosphate ZDDP additive and two different dispersants at an elevated oil temperature for a wide

Zinc dialkyl dithiophosphate ZDDP is one of the most favored antiwear additives that react very rapidly with rubbing surfaces to form tribofilm that reduces wear In this study the experimental work aims to investigate the effect of ZDDP replenishment on tribological performance in the existence of soot and after removing soot from heavy
Zinc dithiophosphate is a coordination compound of zinc and dithiophosphoric acid It is used in anti wear additives to lubricants such as greases gear oils and motor oils Zinc is a metallic element with the atomic number 30 It is found in nature most often as the mineral sphalerite Though excess zinc in harmful in smaller amounts it is
Zinc dialkyldithiophosphate ZDDP provides superior antiwear protection as a lubricant additive Learn about its current use and its future Wikipedia Zinc dithiophosphate; Varlot K Kasrai M Martin J et al Antiwear film formation of neutral and basic ZDDP influence of the reaction temperature and of the concentration
Lab results show that the addition of a minor amount of zinc dialkly dithiophosphate ZDDP is an effective means of improving the performance of most classes of lubricants including those used with water based fluids Downhole conditions of temperature and pressure can provide the necessary conditons for the ZDDP to decompose and form a
Zinc dialkyl dithiophosphate ZDDP is a typical anti wear additive that forms tribofilm on sliding surfaces and prevents adhesion wear but increases the friction force In this study the nano friction and adhesion properties of ZDDP tribofilms were investigated by performing in situ observations by atomic force microscopy to explore the relationship between
