Definitions

  • tall resin or rosin dispersions have a solids content of 30 to 40% by weight, a pH of 6 to 8 and a free resin content of 75 to 97% by weight.
  • the patent owner sells a particularly suitable resin glue dispersion under the RESOPLAN® brand. It is a tall resin dispersion which is reinforced with 7 to 8% by weight of fumaric acid, contains casein as a protective colloid and has a pH of 6, a solids content of 30% by weight and an average particle diameter of 0.5 up to 1 ⁇ m.
  • the diluted solutions of aluminum sulfate and sodium aluminate thus produced are mixed homogeneously in a T-mixer.
  • the flow rate of the aluminum sulfate solution in the mixer is 2.7 m / s, that of the sodium aluninate solution 4.2 m / s.
  • the homogeneous aluminum hydroxide thus formed has a pH of 6.9.
  • the Reynolds number of the colloidal solution of the homogeneous aluminum hydroxide is 25,000. This solution is added to the thin material immediately after it is formed 0.5 m in front of the pressure sorter.
  • 370 g of deinked, but not yet acidified waste paper with a consistency of 5.4% are diluted with tap water to a consistency of 1%, mixed with 1.5% by weight aluminum sulfate and stored in a storage vessel 1 with stirring.
  • the fiber suspension is pumped from the storage vessel 1 into a storage vessel 2 with a delivery rate of 2.0 liters / minute.
  • mixture A RESOPLAN® and RESIAFIX® are diluted with water to a solids content of 50 g / liter and 1.5 g / liter, respectively, and equal volumes of the products thus diluted are mixed in a static mixer. Mixture A is added to the fiber suspension in an amount of 40 ml / minute.
  • mixture B 150 parts by volume of an aqueous solution which contains 1.456 g / liter of commercially available aluminum sulfate with an aluminum content of 17% by weight, calculated as aluminum oxide, with 50 parts by volume of an aqueous solution which , Contains 26 g / liter of liquid sodium aluminate with an aluminum content of 25% by weight, calculated as aluminum oxide, mixed intensively in a T-mixer and immediately after mixing in a quantity of 200 ml / minute of the fiber suspension.
  • Example 2 The procedure is as in Example 2, except that the mixture B consists of 150 parts by volume of the same aluminum sulfate solution as used in Example 2 and 50 parts by volume of an aqueous solution containing 8.093 g / liter of sodium silicate contains a molar ratio NaO: SiO2 of 1: 3.3 and a density of 1.35.
  • Example 2 The procedure is as in Example 2, except that the mixture B consists of 150 parts by volume of an aqueous solution, the 1.456 g / liter of the same aluminum sulfate as used in Example 2 and 1.3 g / liter of RESIAFIX ® contains, and 50 parts by volume of the same sodium aluminate solution as used in Example 2 is prepared.
  • the sheets produced have a basis weight of 80 g / m2. Examination of the finished sheets showed a Cobb 15 value of 54 g / m2. An anionic charge of 6.1 ⁇ eq / liter of polyvinyl potassium sulfate, a hardness of 13.5 ° dH and a pH of 7.4 were measured in the filtrate.
