Problems solved by technology

However, the existing composite additives for hydraulic oils are not effective, and it is difficult to meet the higher requirements of various mechanical equipment, and the comprehensive effect is not obvious.
Moreover, there are fewer suppliers of compound additives for hydraulic oil than suppliers of compound additives for engine lubricating oil, and the price is expensive. Many lubricating oil manufacturers basically use several single-agent blends to produce hydraulic oil. The reduction in production costs will inevitably make The produced hydraulic oil has poor efficacy, short service life and unsatisfactory overall efficacy
