ML-700 cleaning and degreasing agent is a composite of agents with multiple functions such as chelation, cleaning, degreasing, dispersion, and penetration. It has unique effects in degreasing, rust removal, and cleaning, and is a good degreasing and cleaning agent. It can effectively remove dirt on equipment and remove emulsified oil in water and oil film adhered to the surface of pipeline equipment, without generating secondary pollution. The ML-700 cleaning and degreasing agent has a good effect on removing oil that leaks into the circulating water, which is comparable to the degreasing effect of biological enzyme preparations. At the same time, it has water-saving and time-saving properties, does not damage the water balance, and has good compatibility with phosphorus series corrosion and scale inhibitors. ML-700 cleaning and degreasing agent is suitable for cleaning and degreasing oily circulating water systems, mainly used for cleaning and degreasing before pre membrane of new systems, providing conditions for pre membrane.
