Combined phosphate degreaser

When degreasing and phosphating of metal parts are carried out simultaneously, it is called combined phosphate degreaser. In this way, iron phosphate is used with a neutral degreasing agent in spray iron phosphating lines. It should be noted that when using neutral degreasing products, high temperatures are required for the degreasing effect and, compared to iron phosphating baths, the water quality (hardness, conductivity, etc.) must also be higher.

Performance

– Degreasing: The alkaline compounds in this solution dissolve and remove fats, oils, greases, and other organic contaminants from the metal surface.

-Phosphating: After degreasing, the phosphate salts in the solution react with the metal surface and form a thin, crystalline layer of phosphate on the surface. This protective layer increases the adhesion of paint, coatings, and other organic materials and prevents corrosion of the metal.

Advantages

-Reduction of steps: Since both degreasing and phosphating are done in one step, time and cost are saved.

-Increased efficiency: The process is carried out continuously and efficiently.

-Improved adhesion: The phosphate layer created significantly improves the adhesion of paint and other coatings to the metal.

-Corrosion resistance: The phosphate layer protects the metal from corrosion.

Disadvantages

-Environmental hazards: Some of the chemical compounds in these solutions can be harmful to the environment. Therefore, their proper use and disposal is very important.

Metal Restrictions: May not be suitable for all metals.

Overall, combined phosphate degreaser is an efficient and economical industrial solution for preparing surfaces prior to painting or applying other coatings.
