The concentrated solution specifically designed for the electro-hydraulic control of hydraulic supports is primarily utilized in the electro-hydraulic control system of fully mechanized coal mining. Synthesized through "molecular design", its dispersed particle size attains the nanometer level, fulfilling the requirements of the electro-hydraulic control system for a more stable, cleaner, and high-filtration-precision transmission medium. This effectively prevents the medium from clogging components such as filter cartridges, filters, and pilot valves. Additionally, the product's lubricity and rust resistance are significantly enhanced by the use of a self-developed multifunctional lubricating and rust-preventative agent. Furthermore, it exhibits superior rust resistance against ferrous metals and corrosion resistance against non-ferrous metals. This product possesses the following technical features: 1. Nanometer-sized particles, fully meeting the high-precision requirements of electro-hydraulic control systems; 2. Free of mineral oil, environmentally friendly, and exhibiting excellent biodegradability; 3. Excellent water quality adaptability, accommodating a water hardness range of 0 to 2000 mg/L for solution preparation; 4. Outstanding lubricity, excellent corrosion inhibition for ferrous and non-ferrous metals, good compatibility with sealing materials, and adaptability to sealing materials such as polyurethane, nitrile rubber, and polyoxymethylene; 5. Reduced blockage of solenoid valves and pilot valves, ensuring the normal operation of electro-hydraulic control systems and reducing the overall cost of coal mining.
