Scales are formed on a metal surface during heat treatment processes.  Descaling or metal cleaner formulation is a metal cleaning process that removes unwanted surface deposits on metals to provide a smooth surface finish and is a part of the pre-finishing processes which include cleaning, stripping and pickling.

Descaling of metal  refers to the process of removing scales or oxide layers that form on metal surfaces . Due to exposure to high temperatures, corrosion, or other chemical reactions. The scale is a type of metal oxide that can form on the surface of metals like steel, iron, copper, and others. Metal cleaner formulation can reduce the metal’s strength, cause surface irregularities, and negatively impact its appearance. Descaling is essential to restore the metal’s surface to its original condition and improve its performance and aesthetics.

There are various methods for descaling metal, depending on the type of metal, the thickness of the scale, and the specific requirements of the application.

Methods used for  metal clearing

  1. Mechanical Descaling: Mechanical descaling involves physically removing the scale using mechanical means, such as wire brushing, grinding, sanding, or shot blasting. This method is suitable for removing thick scales and surface irregularities.
  2. Chemical Descaling: Chemical descaling utilizes acids or other chemical solutions to dissolve and remove the scale from the metal surface. Acid solutions, like hydrochloric acid or sulfuric acid, are often used for this purpose. The metal is immersed or treated with the acid, which reacts with the scale, converting it into a soluble form that can be easily washed away.
  3. Electrolytic Descaling: Electrolytic descaling uses an electric current to remove the scale from the metal surface. The metal is immersed in an electrolytic solution, and an electric current is passed through it. As it  causing the scale to dissolve and separate from the metal.
  4. Thermal Descaling: Thermal descaling involves heating the metal to high temperatures to facilitate the oxidation and subsequent removal of the scale. The high heat causes the scale to crack and peel off the metal surface.
  5. Abrasive Blasting: Abrasive blasting, such as sandblasting or shot blasting, is a process that uses abrasive materials propelled at high speed. It removes the scale and other surface contaminants.
  6. Ultrasonic Descaling: Ultrasonic descaling utilizes high-frequency sound waves to create cavitation bubbles . It  helps to break up and remove the scale from the metal surface.

Product making guide of metal cleaner formulation

The choice of descaling method depends on factors like the type of metal . The other factors are the  thickness of the scale, the extent of corrosion, and the desired surface finish. It’s essential to consider safety precautions and environmental regulations when performing descaling processes involving chemicals or other hazardous materials.

After descaling, it is crucial to clean and protect the metal surface to prevent further oxidation or corrosion. Proper maintenance and surface treatment can help prolong the metal’s life and maintain its appearance and functionality. This product guides you in the right way to descaling or meter cleaner product manufacturing.
