The alkaline cleaning process is a method of cleaning the metal surface with an alkaline solution, aiming to remove oxides, oil stains, and other impurities on the surface to improve the surface quality and performance of the metal. Our company can provide Molybdenum plates with Alkaline Cleaning Surface, rods, or targets, and can also accept customized services in terms of size specifications and surface treatment. The alkaline cleaning process can be widely used in steel smelting, rolling, galvanizing, and other processes. The specific steps are as follows:
1. Prepare alkaline cleaning solution: Add an appropriate amount of alkaline substance to water, stir evenly, and adjust the concentration of the solution. The concentration of the solution needs to be determined according to the metal material and treatment requirements. Too high or too low a concentration will affect the cleaning effect.
2. Soak the metal parts in the alkaline cleaning solution: Put the metal parts to be treated into the alkaline cleaning tank and ensure that they are completely immersed in the solution. 3. Ensure that the metal surface is exposed to the solution. The soaking time depends on the metal material and treatment requirements. It usually takes a period to ensure thorough cleaning. 4. Stirring the solution: Use a stirrer to stir the solution to keep the alkaline substances in the solution and the metal surface in uniform contact to improve the cleaning effect.
5. Filtering the solution: Use a filter to remove suspended matter and impurities in the solution to keep the solution clean.
6. Pickling: Move the metal parts to the pickling tank to remove the residual alkaline substances to avoid adverse effects on the metal surface.
7. Washing: Use clean water to thoroughly rinse the metal parts to remove the pickling residue.
8. Drying: Dry the metal parts or use appropriate methods to speed up drying.
In actual operation, choose the appropriate type and concentration of alkali solution according to the metal material and surface condition. Appropriate temperature can increase the speed of chemical reaction but avoid excessively high temperature that causes the alkali solution to volatilize too quickly. Too long or too short soaking time will affect the cleaning effect.
