Surfactant is mainly through its wetting, penetration, emulsification and other characteristics,
so that the adhesion of oil on the metal surface is weakened, and then through mechanical and physical
ways to accelerate the oil from the metal surface into the lotion, and is emulsified, dispersed,
can remove the metal surface of oil, dust and other dirt;
can improve the alkaline detergency and emulsify the mineral oil that cannot undergo saponification into the lotion
can be used in the process of pickling to inhibit the production of acid fog, speed up pickling speed and prevent corrosion.
