Definitions

  • Scale formation originates from various causes. One is that the surface of the metal being treated with the composition is attacked by the composition to result in dissolution of the base metal which then reacts with phosphate to form scale. Another is that the phosphate compositions themselves may tend to dissociate to form scale.
  • n is a number from 2 to 8 inclusive, and salts thereof.
  • a particularly preferred material is that sold by Ciba- Geigy (U.K.) Limited under the trademark Belloid, for example Belloid SFD.
  • the dispersing agent may be used in any amount that is effective to give improved results.
  • the improvement that is obtained in the invention vmost usually is a change in the nature of the deposit that is formed.
  • this'cleaning can very easily be effected, for example, by merely rinsing the surfaces carrying the deposit.
  • the high molecular weight dispersing agent may be included in any aqueous acidic phosphating solution comprising scale forming metal ions and phosphate ions employed in the phosphate coating of metals.
  • the solution may be, for example, a zinc phosphate solution or other coating phosphate solution (e.g., containing Mg, Mn or Fe ions). It may also be a non-coating phosphate solution, e.g., a sodium phosphatesolution. Initially, such non-coating solutions are generally free of scale forming metal ions and scale formation is not then a problem. However, during use iron or other metal ions are generated from the surface being treated to yield an acidic solution containing iron or other scale forming ions such as those of aluminum or zinc. Accordingly, scale formation again becomes a problem, even though the amount of iron may be less than the amount of heavy metal in a coating phosphate solution. Thus, scale formation in both coating and non-coating solutions can be reduced or eliminated by the invention.
  • the dispersing agent may be included in concentrates, either aqueous or non-aqueous, that are diluted before use to form a working solution or it may be added directly to a working solution.
  • the solution may contain any of the various additives known in the art.
  • concentration of the various components of the solution will be selected having regard to the end use. For example lighter coatings, and therefore lower concentrations, are required when the coating is to serve as a paint base than when it is only to provide corrosion resistance.
  • Typical concentrations and components for a zinc phosphate solution include the following:
  • the metal surface to be treated is washed, rinsed and then has the zinc phosphate solution applied to it, normally by spray or immersion. Conventional further treatment, such as rinsing and drying, may be conducted. Application of the treatment solution is normally carried out at elevated temperatures, for ex- 3 ample 100 to 200F and preferably 130 to 170F.
  • the metal surface treated may be zinc, aluminum, iron (or alloys containing predominant amounts of these).
  • an aqueous acidic phosphating composition containing scale forming metal ions comprising including at least 0.0005% of'a naphthalene sulfonic acid/formaldehyde condensation product or a salt thereof.
  • composition of claim 1 wherein the naphthalene sulfonic acid/formaldehyde product has the general formula:
  • composition of claim 2 wherein said scale forming metal is selected from the group consisting of zinc, manganese, magnesium, iron, aluminum and cal-
