Product Description

ZH-2 is a kind of cationic imidazoline corrosion inhibitor. It is also a kind of water soluble inhibitor. There are polar group and non-polar group in ZH-2 molecular structure. With polar group adhering to the surface of metal and non-polar group being placed closely on the surface of metal, lyophobic oil film is formed. The existence of oil film stops the movement of electricity charge or materials that are related to corrosion reaction. Therefore, ZH-2 can be used for preventing pipes from being corroded in the process of exploration and transportation of oil and gas field, and can prolong service time of pipes. The recommended dosage is 20-200ppm.
