Product treatments for an optimal result
Chemical pickling
The term pickling refers to a chemical process of removing metal oxidations.
In the case of copper, pickling is necessary in order to effectively remove the layers of surface oxides that form on the surface, or as a result of heat treatments or due to corrosion.
In addition to bringing the metal back to its original color, pickling is essential if you need to proceed with subsequent treatments (galvanizing processes, painting, etc.)
One of the main aesthetic reasons is the removal of slag and welding oxides, in order to obtain a clean and uniform external surface.
Galvanizing
Galvanizing is the most efficient and effective chemical process for protecting steel from corrosion.
The piece to be treated is first pickled and degreased, in order to be ready for the application of the zinc layer.
The material is subsequently immersed in a special electrolyte solution based on zinc salts.
By creating an electrical current between the part and the solution, the metallic zinc will settle on the surface of the piece itself.
The electrolytic treatment allows us to obtain an excellent corrosion resistance even with low levels of thickness of zinc, considerably lengthening the life time of the material.
Nickel Plating
The nickel-plating process is able to give greater resistance to wear and corrosion to products.
-
The chemical nickel-plating is a nickel deposit with high resistance to wear and anti-friction.
The deposit takes place chemically without the use of electric current, thus allowing the treatment on any secondary layer and shape.
Being a chemical and not an electrolytic process, a coating of extremely uniform thickness is obtained independently of the shape of the object. -
Electrolytic nickel-plating requires an accurate cleaning of the piece before treatment.
Once the preparation has been completed, the piece is fully immersed in a bath of electrolytic solution, and placed as a cathode, using instead as an anode of nickel dissolved in the liquid in ionic form.
As usual in the electrolytic process, the metal atoms travel in the solution and settle on the piece, completely covering it.
Anodizing
Anodizing is a process that uses acidic substances to create a protective layer of oxide on the surface of a metal.
Mainly this treatment is used for aluminum products.
The anodic layers are made for the following purposes:
- Improve corrosion resistance
- Improve resistance to wear and abrasion
- Effectively apply paints or lubricants
- Give a particular aesthetic appearance
Teflon
Teflon is a thermoplastic polymer, immune to any chemical substance.
It does not contaminate the substances with which it comes into contact, leaving its characteristics unaltered.
The advantages of using Teflon-coated pipes are:
- Longer life, because it is very resistant to corrosion.
- Resistance to high temperatures.
- Better operating and safety conditions, reduction of losses of harmful substances and vapors thanks to Teflon coatings.
- High compatibility with almost all materials.
- Resistance to abrasion and wear, preserving the characteristics of hardness and resistance.
