Definitions

  • the invention relates to glycol-free, frost resistant cooling and heat transference liquids on potassium-acetate - potassium formate basis, as im ⁇ provement to the solution of Hungarian patent No. 203 776, having the same subject matter.
  • Said patent gives detailed discussion and summary of the state of the prior art and indicates the task aiming at a more advantagous satisfaction of need compared to it.
  • the goal to be achieved by the present patent application lies in an improvement by modificating of the liquid's com ⁇ position ensuring an efficacious protection against corrosion even if having been mixed with usually applied cooling liquids on glycol basis and meeting the more exacting hygienic requirements in heat exchangers of water for consumption as well as in heating systems, such as in radiators.
  • the achievement of the aim set recently could be based on the obser ⁇ vation that, if a water-soluble lubricant, preferably glycerine is added to the heattransferene liquid in a ratio of about 4 to 6 mass%, this lubricant, be ⁇ sides protecting the mobile metallic surfaces against friction, can impede the formation of the local concentration ceils and, in this way, so can the possi ⁇ bility of the pitting and crevice corrosion even at identic inhibitor composition by ensuring the uniform distribution of the inhibitors in the adhering liquid film.
  • a water-soluble lubricant preferably glycerine
  • the liquid may contain in a given case besides the glycerine and the usual quantity of the other inhibitors listed, benzo-and tolyl-triazoie respectively.
  • the present invention is characterized in that the frost resistant cooling and heat-transference liquids contain as erosion-and corrosion hin ⁇ dering components 4-6 mass% glycerine, 0,8-0,9 mass% alkali-benzoate, 0,08-0,12 mass% alkali-polymetaphosphate and 0,02-0,04 mass% borax, and in a given case 0,15-0,20 mass% benzo-or tolyl-triazoie.
  • Example 1 Moderately frost resistant cooling liquid variety One ton liquid is produced by blending of 649,3 kg water, 189,4 kg caustic potash solution of 50 w%, 84 kg acetic acid solution of 96 w%, 16 kg formic acid solution of 99 w%, 50 kg glycerine of technical quality, 8,3 kg sodium-benzoate, 1 ,7 kg tolyl-triazoie, 0,5 kg sodium-trimeta-phosphate, 0,5 kg sodium-hexametaphosphate and 0.3 kg borax (dissolving under stirring and cooling).
  • the concentration of the acids and that of the alkali may obvi- sously be different from that as it is given above. If so, the proportions are to be varied according to the sense.
  • the crystal point of the liquid produced in this way (in other words: its theoretic, i.e. thermodynamic freezing point) is - 10°C but the separated, loose crystals containing liquid can be used even at -16°C (lower temperature
  • Example 3 Cooling liquid variety frost resistant in an increased degree To one ton of the make 216,1 kg water is blended with 472,6 kg caus ⁇ tic potash of 50 w%, 210 kg acetic acid of 96% and 40 kg formic acid of 99 w%, the further components are unchanged.
  • the crystal point of the liquid produced in this way is -45°C, its lower temperature limit, however, is -70°C.
  • optional other varieties can also be manufactured by interpolation, according to the prescribed frost resis ⁇ tance.
  • the given freezing points do not practically change if the liquids are blended with ones on glycol basis of identic freezing point.
  • the mixing of liquids of different freezing point results in freezing point that can be esti ⁇ mated by proportionate interpolation.
  • Another important advantage of the inhibotor composition elaborated is inherent in its compatibility with the in ⁇ hibitors generally used in antifreeze makes on glycol basis. All these enables to keep the inhibitors' concentration constant, independently of that of the freezing point depressants, as shown in the examples. In this way it can be attained, that the liquid is not diluted with respect to the inhibitors but will contain their optimum concentration, regardless of whatever dilution needed corresponding to the lesser frost resistance requirement.
  • Middling frost resistant liquid of health safety in an increased degree To one ton of the product 523,8 kg water, 272,6 kg caustic potash of 50 w%, 121 kg acetic acid of 96 w%, 23 kg formic acid of 99 w%, 50 kg glycerine, 8,3 kg sodium-benzoate.
  • 0,5 kg sodium-trimetaphosphate, 0,5 kg sodium-hexametaphosphate and 0,3 kg borax are to be blended.
  • the crystal point of the liquid is -23°C, whilst its lower temperature limit is -36°C.
  • the pH of the liquids manufactured in the treated way is in any case in the range of 8,7 ⁇ 0,1. If there is a departure therefrom due to the fluctuation of the components' water content, a small quantity of acid or alkali is to be added to set the pH prescribed.

Abstract

Liquide de refroidissement caloporteur et résistant au gel. Ce liquide est à base d'acétate de potassium et de formiate de potassium, et il renferme, à titre de constituants inhibant l'érosion et la corrosion, de 4 à 6 % en poids de glycérine, de 0,8 à 0,9 % en poids de benzoate alcalin, de 0,08 à 0,12 % en poids de polymétaphosphates alcalins, et de 0,02 à 0,04 % en poids de borax. On maintient à une valeur optimale la concentration des constituants inhibant l'érosion et la corrosion, et ce, indépendamment de la teneur en eau du liquide. Selon un mode de réalisation, il s'agit de 0,15 à 0,20 % en poids de triazole benzoïque ou tolylique.
