Main components of acid pickling corrosion inhibitor

Posted on September 11, 2023 By admin No Comments on Main components of acid pickling corrosion inhibitor

Pickling corrosion inhibitor is a chemical agent used in the pickling process of metal surfaces, mainly used to remove oxides, rust, and other pollutants from metal surfaces, and provide corrosion protection. The specific components of acid pickling corrosion inhibitors vary depending on the product brand and model. The following are some common components:

Corrosion inhibitors: Common corrosion inhibitors include organic acids (such as acetic acid, oxalic acid, citric acid, etc.) and inorganic salts (such as phosphates), which can form a protective corrosion film with the metal surface to reduce further metal corrosion.

Cleaning agents: Acid pickling corrosion inhibitors usually contain cleaning agent components, which are used to remove dirt, grease, and other impurities from metal surfaces to ensure better acid pickling effect.

Surfactants: In order to increase the wettability and permeability of pickling solution on metal surfaces, pickling corrosion inhibitors often contain surfactants to help the solution better contact and clean the metal surface.

Acidic substances: The main function of acid pickling corrosion inhibitors is to provide an acidic environment. Common acidic substances include sulfuric acid, hydrochloric acid, phosphoric acid, etc., which can dissolve oxides and rust layers on metal surfaces.

It should be noted that when using acid pickling corrosion inhibitors, safety operating procedures must be followed, and protective measures must be taken, such as wearing protective glasses, gloves, and appropriate protective clothing. Before using acid pickling corrosion inhibitors, please carefully read and follow the product instructions for proper use and treatment. For professional metal pickling processes, it is recommended to consult or entrust professionals or service providers for operation.
