Definitions

  • adhesion fluxes any of the substances are included which, within the scope of the invention as hereinafter fully set forth, are capable of producing, by their reaction on the coating metal after the fusing of the same, in combination with. the subsequent cooling as by treatment with water or aqueous solutions, a smooth, bright coating, free from pores.
  • . is band isled from a supply table 1 or a roller or the like, and is continuously fed by suitable feeding devices to the various parts of the plant in succession and, when finished, wound upon a winding drum or roller 20.
  • the several apparatus of the plant are the following:
  • 2 is a pair or set of pressure rollers serving. on t forward and on the other hand for ressing o'ut'or smoothin down the folds a2. etween the consecutive en s or sheets.

  • 4 is a rinsing apparatus which -frees the band from any impurities remaining after the removal of fatty matter.
  • 5' is an electric pickling apparatus in which in well known manner the and is thoroughly ickled by means of a pickling bath through which an electric'current is passed.
  • the pickhng bath 5 and the electroplating cell 6 further apparatus (not shown in the drawings) well known in themselves for removing fatty matter for rinsing, brushing and again rinsin the band is, .by which means the cleaning of the 'band is completed.
  • 6 is the electro lating bath.
  • 7 is an elastic air of rollers by which the excessof li ui adhering to the "band after electrodeposition of the coatin is removed.

  • t c said pr ocess consists in treating the electrolytically coated goods before or during fusing of the galvanically deposited coating with an adhesion flux and in subsequently treating in water or aqueous solutions the deposited coating preferably whilev warm which has been fused in the presence of the dried adhesion flux the goods being of course cooled at the same time.
  • adhesion flux in the absence of exact scientific explana-' tion of what takes place in the present process is to be interpreted in the widest sense. It is essential that the adhesion flux used should be adapted when split up upon the fusion of the coating to cause a perfectly smooth adhesion free from pores. In other words the adhesion flux must be of such a nature that the fused coating on solidifying thoroug gl y intimately adheres to the ground metal and forms a bright surface free from any pores, as these condition are essential for the perfect protection of the ground metal against-the deleterious atmospheric action which is the main object of -the coating.
  • the adhesion flux should preferably be of such a nature that the oxides formed on fusing the coating combine with the residues of the adhesion flux to form substances which are soluble in water and may be readily removed.
