Usage of acid pickling corrosion inhibitor

Pickling corrosion inhibitor MBT 2-Mercaptobenzothiazole is a chemical reagent used for metal surface pickling treatment, mainly used to remove oxides, rust, and other pollutants from metal surfaces, and provide corrosion protection. The following are general usage guidelines for acid pickling corrosion inhibitors:

Pre treatment: Before acid pickling, the metal surface must be cleaned thoroughly to remove grease, coatings, and pollutants from the surface. Alkaline cleaning agents or solvents can be used for pre-treatment.

Preparation solution: Prepare the pickling solution in an appropriate container according to the product manual of the pickling corrosion inhibitor. Usually, it is necessary to add the pickling corrosion inhibitor to the water at the recommended concentration and ensure sufficient stirring to achieve uniform mixing.

Temperature control: Control the temperature of the pickling solution according to the requirements of the pickling corrosion inhibitor. Generally speaking, the temperature of the solution will affect the pickling effect and reaction rate. The solution can be heated or cooled to reach the desired temperature.

Soaking time: Completely immerse the metal parts to be treated in the pickling solution and soak according to the time specified in the product manual. The soaking time generally ranges from a few minutes to several tens of minutes, depending on the type of metal, surface conditions, and requirements for acid pickling corrosion inhibitors.

Rinse: After pickling, rinse the metal surface thoroughly with clean water to remove residual pickling solution and generated waste. Ensure thorough flushing to prevent residual pickling agents from affecting subsequent processes or coating quality.

Surface treatment: Further surface treatment, such as neutralization treatment, coating, coating, etc., shall be carried out as needed.

It should be noted that when using acid pickling corrosion inhibitors, safety operating procedures must be followed, appropriate personal protective equipment must be worn, good ventilation must be ensured, and relevant regulations and environmental protection requirements must be followed. In addition, there may be differences in pickling treatment for different metals and specific situations, so it is recommended to operate according to specific product manuals and process requirements.
