Typical problems
At high temperatures, industrial oils easily oxidize and break down, which leads to increased sludge formation and an increase in acid number. Not only does this increase operating costs due to frequent oil changes, but it can also shorten equipment life. How to solve the problem of high-temperature oxidation of oils and reduce total procurement costs?
Solution: Our L57 line is high temperature amine antioxidants. By capturing free radicals, they interrupt oxidation chain reactions and thereby initially increase the thermal stability of the oil. In practice, when added to hydraulic oils or coolants at a concentration of 0.1-0.5% - as a professional additive for hydraulic oils - it effectively suppresses oxidation and the increase in acid number during high-temperature operation. Our technical team, using synergy with phenolic antioxidants, has achieved that it has a long-lasting effect at high temperatures that is superior to conventional hindered phenols.
