Definitions

  • This Patent of Invention relates to a new procedure for preparing suspensions of salts of ammoniac, primary amines, secondary amines, tertiary amines and zinc at high concentrations and presenting optimum stability and fluidity and especially ideal ease of application, as a disintegrating agent for various copper compounds or alloys thereof, which form over time (ageing), while at the same time lowering the melting temperature of alloys of tin, lead and silver at multiple concentrations, and in the form of bars, wire or powder, with copper or alloys thereof, thus permitting, with the application of heat, the diffusion of the additive alloy on the surface of the copper compounds.
  • This invention has achieved a stable suspension of the chemical components at a high concentration, thus lending the product a consistency such as to avoid accidental spillage, while permitting it to be applied by brush, thereby achieving a hygienic way of working. Chemically, it is difficult at such high concentrations to achieve a fluid suspension which is stable over time.
  • the procedure of this invention is characterized by the utilization of a suspending or emulsifying agent formed by a mixture of one, two or three of the following components, in multiple proportions:
  • Example 1 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 25 grams of zinc chloride, 5 grams of ammonium chloride and 17 grams of the mixture of polyethylene glycol ethers with the fatty alcohols; the mixture is then cooled with agitation.
  • Example 2 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 15 grams of zinc chloride, 10 grams of dichloride of zinc and ammonium and 17 grams of the mixture of polyethylene glycol ethers with the fatty alcohols; the mixture is then cooled with agitation.
  • Example 3 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 25 grams of zinc chloride, 5 grams of ammonium chloride, 10 grams of finely powdered mixture of tin, lead and silver, in various proportions, and 17 grams of the mixture of polyethylene glycol ethers with the fatty alcohols; the mixture is then cooled with agitation.
  • Example 4 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 15 grams of zinc chloride, 15 grams of triethanolamine and 17 grams of the mixture of polyethylene glycol ethers with the fatty alcohols; the mixture is then cooled with agitation.
  • Example 5 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 20 grams of zinc chloride, 15 grams of triethanolamine and 13 grams of the mixture of fatty alcohols and fatty acid salts, and 5 grams of the mixture of polyethylene glycol ethers with the fatty alcohols; the mixture is then cooled with agitation.
  • Example 6 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 15 grams of zinc chloride, 15 grams of dichloride of zinc and ammonium and 17 grams of the mixture of fatty alcohols and fatty acid salts; the mixture is then cooled with agitation.
  • Example 7 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 25 grams of zinc chloride, 5 grams of ammonium chloride, 10 grams of finely powdered mixture of tin, lead and silver, in various proportions, and 17 grams of the mixture of fatty alcohols and fatty acid salts; the mixture is then cooled with agitation.
  • Example 8 100 grams of water are heated to a temperature of 85-90°C and the following components are then added, with mechanical agitation: 15 grams of zinc chloride, 15 grams of paraphenylendiamine hydrochloride and 17 grams of the mixture of fatty alcohols and fatty acid salts; the mixture is then cooled with agitation.
