Pickling corrosion inhibitor is a chemical used in the pickling process of metal surfaces, which mainly includes the following components:
Corrosion inhibitor: The main component of acid pickling corrosion inhibitor is corrosion inhibitor, which can form a protective corrosion film, reduce direct contact between metal and acid solution, and reduce corrosion and erosion of metal. Common corrosion inhibitors include organic amines, phosphates, phosphates, nitric acids, etc.
Surfactants: Surfactants are often added to acid pickling corrosion inhibitors to improve their wettability and permeability, enabling corrosion inhibitors to better adhere to metal surfaces and improve cleaning efficiency. Surfactants can be of different types, such as non ionic, anionic, or cationic.
PH regulator: In order to provide suitable acidity and alkalinity for pickling corrosion inhibitors, pH regulators are generally added to control the pH value of the pickling solution. Common pH regulators include hydrochloric acid, sulfuric acid, phosphoric acid, etc.
Additives: According to specific applications and requirements, pickling corrosion inhibitors can also add other auxiliary components, such as anti foaming agents, thickeners, dyes, etc., to improve the operational performance of the pickling process or achieve specific effects.
It should be noted that different pickling corrosion inhibitors have different composition combinations and ratios, and the specific composition may vary depending on the manufacturer, product type, and application field. Therefore, in practical use, it is recommended to follow the product manual and relevant standards for guidance and use.
