- Model F - Formulation Removal Chemical

0

To be used wherever it is necessary to remove or reduce FLUORIDES. This chemical formulation removes up to 99% of the Free and complex Fluorides.

  • Used in the purification of water from stainless steel, aluminum and special metals pickling (Cu, Ni, Cr, ...)
  • Used in the purification of water from Anodizing, stainless steel, aluminium pickling and steel sulphuric pickling.
  • For Z.L.D. (Zero Liquid Discharge) process
  • Used in the treatment of wastewater for removal of heavy metals.

The chemical pickling is an operation carried out to remove surface layers of a material by means of acid solutions. The surface is thus cleaned of rust residues formed from the hot-rolling operation such as surfactants (soaps that increase the wettability), corrosion inhibitors or other chemicals, mill scale and other contaminants, in order to make the surface of the metal suitable to be covered by another finishes. After the pickling, the treated surface becomes porous and allows the other materials to bond securely to the one below.

The process of phosphating aluminum and steel parts is typically listed as a conversion coating because the process involves metal removal as part of the reaction. The final surface is a layer of very fine phosphate crystals adhering to the surface of the metal.

Chromating is applied on aluminium or its alloy, as a coating pre-treatment as it provides high-quality adhesion and excellent protection against corrosion. General method is to clean the aluminium surface and then apply an acidic chromium composition on that clean surface.

Chrome free treatment is applied on aluminum and its alloys, surfaces instead of Chromating . The coat is based on titanium or zirconium oxides. While the bath contain also fluorides to form Al F3 complex

After any chemical operation, water rinses are used to reduce the risk of introducing unwanted chemicals to subsequent baths. Rinses system may be optimized by using either a 2 or 3 cascading rinse tank configurations in order to maximize rinses quality and minimize consumprion of water.

Sometimes the cleaning operations is done with an Acidic bath instead of Alkaline bath. This is true for Aluminium processing prior to Phosphating, Chromating or Chrome free treatments.

Any rinses following an Acidic step will be Acidic as a result of the Acid being carried over

Some Nanotechnolgy treatment process require final rinses and some do not.

Extrusion

In metal finishing field, Aluminium is the most commonly extruded material. Aluminium can be hot or cold extruded. If it is hot extruded it is heated to 575 to 1100 °F (300 to 600 °C).Examples of products include profiles for tracks, frames, rails, mullions, and heat sinks.

Aluminum

Coil coating and pickling

Coil coating makes use of a simple, but effective principle, to clean, pretreat and coat flat coils or sheets of steel or aluminium in a continuous operation, before other stages of industrial manufacture. Pickling is the cleaning part of this operation where acids are used to remove oxide layer and other impurities.
