Hydrochloric acid continuous pickling corrosion inhibitor

Hydrochloric acid continuous pickling corrosion inhibitor is a chemical agent used for metal surface treatment on continuous production lines, mainly composed of hydrochloric acid, phosphate corrosion inhibitors, surfactants, corrosion inhibitors, etc. It can effectively remove oxide skin and pollutants from the metal surface, improve its surface quality and rust resistance. The following is a conventional hydrochloric acid continuous pickling corrosion inhibitor formula:

Hydrochloric acid (concentration 37%): 150-170 g/L

Phosphate corrosion inhibitor (such as epoxy propane acrylic acid copolymer, etc.): 1-3 g/L

Surfactants (such as sodium dodecylbenzenesulfonate, sodium octylbenzenesulfonate, etc.): 0.5-1.5 g/L

Corrosion inhibitors (such as copper nitrate, zinc nitrate, etc.): 0.5-1.5 g/L

Mix and stir the above ingredients in a certain proportion. It should be noted that in practical applications, the composition and proportion of the formula may vary depending on factors such as production line conditions, types of metal materials, and processing requirements. Therefore, before using hydrochloric acid continuous pickling corrosion inhibitor, sufficient testing and adjustment should be conducted to ensure good pickling effect and surface quality.

When using hydrochloric acid continuous pickling corrosion inhibitors, the following points should be noted:

Control the concentration and temperature of the pickling solution to avoid excessive corrosion or deformation of the metal.

Ensure the stability and consistency of dosing and discharge, and avoid any impact on the production line and the environment.

Take protective measures to avoid splashing and corrosion of acid washing solution from causing harm to human health and equipment.
