| De Nora manufactures a variety of different anode
coatings to meet the varied and demanding performance expectations of
the plating industry. De Nora ’s DSA® (Dimensionally Stable
Anode) anode coatings are used in many applications, including but not
limited to, electro-galvanizing (high speed continuous sheet strip and
wire plating), balancing anodes for soluble anode baths and in metal
recovery cells for waste water treatment. |

Electrogalvanizing Anodes – EGL
Zinc plating of steel
sheet in a continuous steel processing line. This sheet is used
primarily for the automotive and appliance markets.
De Nora ’s DSA® anodes offer significant advantages over competing
soluble and insoluble production systems. Compared to soluble
anode systems in zinc sulfate electrolytes, DSA® anodes: |
 |
- Improve plating uniformity
- Reduce energy consumption with smaller anode-to-strip
gaps
- Improve line operations due to better gap stabilty
- Permit higher plating current densities
Relative to other insoluble anode systems, DSA® anodes
offer:
- Power cost savings from constant anode-to-strip
gap
- Insolubility does not require expensive contaminant
removal
- Better quality product with fewer pollution problems

| TiFace™ is an anode surface treatment developed
to repair anodes that were damaged during operation in an electro-galvanizing
high-speed, continuous strip, plating line. The treatment,
unlike traditional approaches at the time, recovered the integrity
of the anode surface thereby allowing the anodes to be recoated.
In addition, the TiFace™ treatment doubled the surface area
of the anodes thereby prolonging the life of the coating. This
technology revolutionized the high-speed, strip steel electrogalvanizing
industry. |

Pickling Anodes
In recent years DSA® anodes have been successfully used as a
direct replacement of conventional anodes made of Lead (Pb) cladding
over copper or steel substrates. The use of De Nora ’s inert
DSA® type anodes eliminates the risk of any additional toxic or
hazardous substances being introduced to the process line. This
thereby reduces or eliminates costs associated with hazardous
waste disposal and the worries of Lead contamination on the finished
product. |

Tin Plate Anodes for Tin Line
The use of DSA® anodes for Tin Lines is another important use
of the titanium anodes with iridium oxide anode coatings. These
anode are typically used for
balancing (plating out excess tin) of the dissolved tin in a Methane Sulfonic
Acid (MSA) bath or in a Phenyl Sulfonic Acid ( PSA ) bath or for tin
plate lines which use DSA® anodes as the main anode for the tin
plating. |
