Definitions

  • the present invention relates to auxiliaries.
  • the present invention relates to auxiliaries for stabilizing bleaching solutions used for wood pulp bleaching, in particular when using bleaching solutions containing peroxide and / or sulfite.
  • the bleaching of the wood pulp necessary for use as a raw material in paper production is generally carried out with the aid of hydrogen peroxide and / or dithionite or hydrosulfite.
  • the bleaching can be carried out in one or two stages.
  • the bleaching result is influenced by the type of wood and wood pretreatment, the amount of bleach, the water quality, the Dosage and the type of additives.
  • the average increase in white for one-step bleaching is 8-10 points, for two-step bleaching 16-19 points.
  • the aim of the present invention was therefore to develop products which allow complete replacement of the water glass in the peroxide bleaching of wood pulp and which also have a bleaching support in the case of the dithionite bleaching.
  • Gluconic acid citric acid, N, N-dihydroxyethylenegycin, diethylenetriaminepentaacetic acid, ethylenediaminetetraacetic acid, nitrilotrisacetic acid or the corresponding salts of these acids.
  • the corresponding alkali and alkaline earth metal salts of orthophoric acid b and polyphosphoric acids can be used as the phosphate component.
  • a bleaching formulation can have the following composition:
  • Example 2 as example 1, but 4% water glass was replaced by 1% of the specified compound.
  • Example 3 as example 1, but instead of 4% water glass 1% of combinations of the compounds mentioned in example 2
  • Example 4 Experimental procedure as in Example 1, but with a combination of three substance groups.
  • the test was carried out at a consistency of 5% under inert gas.
  • the pH was 6, the equilibrium temperature was 60 ° C., the residence time was 1 hour.
  • the bleaching aid was metered in at 1%, as was the Na 2 S 2 O 4 .
