Definitions

  • the amount of anionic colloid which is added to the stock should suitably be within the range of from 0.005 to 2 per cent by weight, preferably from 0.01 to 0.4 per cent by weight, based on dry cellulose fibres and optional fillers.
  • the concentration of the colloid, preferably colloidal silica, in the sol added to the stock is not critical. From a practical point of view it is suitable that the sols at the addition to the stock have a concentration of from 0.05 to 5.0 per cent by weight.
  • the anionic colloid was an alkali stabilized silica sol with a specific surface area of 500 m2/g.
  • the cationic synthetic polymer was a cationic polyacrylamide of medium cationicity sold by Allied Colloids under the name Percol 292.
  • the sodium aluminate was added in the form of a 0.025% aqueous solution and the given amounts of aluminate are expressed as kg Al2O3.
  • the additions of chemicals were made to 1 l diluted stock (about 0.3%) with intervals of 15 seconds under agitation in the order aluminate, cationic polymer, inorganic colloid.
  • the flocked stock was transferred to the freeness apparatus and measurements were made 15 seconds after the last addition.
  • the water which is collected is a measurement of the dewatering effect and is expressed in ml Canadian Standard Freeness (CSF).
  • CSF Canadian Standard Freeness
  • a groundwood stock was used which did not contain any fillers.
  • the cationic polymer was the same polyacrylamide as in Example 1.
  • the anionic colloid was an aluminum modified, 15% alkali stabilized, silica sol where the surface of the colloidal particles had been modified with 9% aluminum atoms and the surface area of the particles was 500 m2/g.
  • the order of addition was sodium aluminate, cationic polymer followed by anionic colloid. Tests were made both with a stock pH of 6 and a stock pH of 7.5 whereby the pH had been adjusted with diluted H2SO4 and diluted NaOH respectively.
  • Example 3 a groundwood stock with addition of 0.5 g/1 of Na2SO4.10H2O was used as in Example 3.
  • the pH of the stock was 6.5 and the added chemicals were sodium aluminate, a cationic polyethylene imine sold by BASF under the name Polymin SK and an anionic colloid which was a bentonite colloid having a specific surface area of from about 400 to 800 m2/g in water.
