Maxtop Coal mine support emulsified oil is refined from deeply refined lubricating oil as the base oil, with the addition of antioxidants, oiliness agents, extreme pressure agents, rust inhibitors, defoamers and multiple emulsifiers. It features excellent extreme pressure, lubrication, cooling, stability, emulsification performance, rust prevention and corrosion resistance. Containing extreme pressure and anti-wear additives, it effectively reduces the wear of plunger pumps and hydraulic valves. The antifoaming agent system ensures the efficient pressure transmission of the hydraulic system, avoids cavitation, and ADAPTS to complex water quality environments.
