Corrosion and scale inhibitor
Chemical substances or compounds that can prevent or slow the corrosion of materials when present in the environment (medium) in an appropriate concentration and form, so corrosion inhibitors can also be called corrosion inhibitors. Its dosage is very small (0.1% ~ 1%), but the effect is remarkable. This method of protecting metals is called corrosion inhibitor protection. Corrosion inhibitors are used in neutral media (boiler water, circulating cooling water), acidic media (hydrochloric acid for removing scale from the pot, acid leaching solution for removing rust from plating parts before electroplating) and gas media
