Definitions

  • the invention relates to a method for the rapid dissolution of water-soluble polymers.
  • Water-soluble synthetic or natural polymers are used for a wide variety of technical purposes. Their use in the form of very dilute aqueous solutions as flocculation and sedimentation aids and as retention aids in the paper industry is particularly known.
  • the polymer emulsion is added to the water provided (and not vice versa), as well as the presence of a wetting agent when the polymer emulsion is brought into contact with water.
  • the desired rapid resolution is only obtained if these two conditions are met. If the procedure is reversed, ie if water is metered into the water-in-oil emulsion of the polymer, there is no rapid dissolution. Rather, it must be stirred intensively to dissolve it. A quick dissolution is also not obtained if the polymer emulsion is added to the water in the absence of a wetting agent.
  • the invention relates to a method for rapid dissolution in water, which is characterized in that water is introduced into the finely divided polymer under pressure in a finely divided state.
  • the water is advantageously injected at a pressure of at least 20, preferably> 25, in particular 50 to 80 bar. It has proven to be particularly advantageous to add the water tangentially to the surface of the polymer initially introduced, as a result of which very good mixing is achieved.
  • the known water-soluble synthetic or natural products are suitable as polymers for the purposes of the invention, for example polymers and copolymers of acrylic acid, acrylamide, methacrylic acid, methacryiamide, vinylpyrrolidone, acrolein, vinyl-containing quaternary ammonium salts and natural gums.
  • hydrophilic wetting agents which reverse the water-in-oil emulsion or the suspension of the powdery polymer in oil to form an oil-in-water emulsion.
  • the wetting agent used is hydrophilic and water-soluble. It is used in amounts of 0.01 to 20%, based on the polymer, with wetting agent amounts of 1.0 to 10% being sufficient for practical purposes.
  • wetting agents oxyethylated alkylphenols, e.g. B. nonylphenol-9-EO, Na or Ka soaps of higher fatty acids, fatty alcohol sulfates.
  • the wetting agent can either be added separately after the addition of water or shortly before or added together with the injected water.
  • the flocculation test subsequently carried out on an aqueous clay suspension (18 g blue shade Witterschlick / l) gives a flocculation value of 4 seconds when 1 ppm of polymer is added.
  • Example 2 1.2 kg of an anionic 25% E-polymer from Example 1 are dissolved according to the method of Example 1, but the product initially added is mixed with 10 l of water and immediately afterwards by adding 88.8 l of water through the water lance solved a pressure of 80 bar. After about 4 minutes, a homogeneous 0.3% solution of the polymer with a viscosity of 800 mPas is obtained.
  • the flocculation test subsequently carried out on an aqueous clay suspension (18 g blue shade Witterschlick / l), when 1 ppm of polymer was added, gave a flocculation value of 4 seconds.
  • the flocculation test subsequently carried out on an aqueous clay suspension (18 g blue shade Witterschlick / 1) gives a flocculation value of 5 sec when 2 ppm is added.
