What Is The Difference Between Ashless Antiwear Hydraulic Oil And Ordinary Antiwear Hydraulic Oil?
Anti-wear hydraulic oil additive system is divided into gray (zinc) type formula and ashless type formula.
The ash type is: zinc-containing main agent ZDDP zinc dialkyl dithiophosphate, whose standard is bounded by 0.03% zinc in oil.
The ashless type is: no zinc. The advantage of the ashless type is that it does not contain zinc and does not reflect with the silver parts. Because many components, such as valves, use silver-plated materials, zinc will be electroplated with silver to reflect silver and destroy parts.
