Definitions

  • the present invention relates to a procedure for the production of mechanical pulp from a fibrous product.
  • the production of mechanical pulp from a fibrous product, such as whole wood, wood chips, chips or refined pulp is mainly implemented by mechanical methods.
  • the production of mechanical pulp is based on the utilization of friction. Energy is transferred to the wood in a compress-release process generating frictional heat which softens the wood so that individual fibres can be released.
  • the object of the present invention is to create a solution that allows the refining energy requirement to be reduced from its present level.
  • the invention is characterized in that the fibrous product is subjected to an enzyme treat­ment in which an enzyme acts on the lignin in the fibrous product.
  • an enzyme treat­ment in which an enzyme acts on the lignin in the fibrous product.
  • the raw material sub­jected to enzyme treatment may be either whole wood, wood chips, or pulp refined one or more times.
  • the enzyme action requires a good contact with as large a fibre area as possible.
  • the purpose of the enzyme treatment is to modify the struc­ture of the lignin in the fibres in such a way that the fi­bres will come apart more easily during mechanical refin­ing.
  • the desired result is achieved by treating the fibrous product with an oxidizing enzyme and adjusting the redox potential with a suitable oxidation-reduction chemical.
  • the enzyme to be used is preferably phenoloxidase, lignin peroxidase, manganese peroxidase or a mixture of these.
  • a suitable enzyme is the phenoloxidase or laccase produced by white-rot fungus Coriolus versiculum.
  • the temperature range of the enzyme treatment may be 10-90°C, preferably 40-70°C, and the pH range 2.0-10.0, preferably 4.0-8.0.
  • oxidiz­ing enzymes such as phenoloxidase, lignin peroxidase and manganese peroxidase are used
  • suitable oxida­tion-reduction chemicals or redox regulators e.g. gaseous nitrogen or oxygen, antioxidants, sugars or sugar deriva­tives, organic acids or inorganic salts, used either by themselves or in mixtures.
  • sodium hydroxide in an amount of 4% of the dry matter of the mixture was added to the mixture. The mixture was then stirred manually for 30 min., whereupon it was concentrated, centrifugalized, homogenized and frozen.
  • the pulp was refined in a Sprout Waldron d 30 cm refiner with a diminishing blade distance.
  • the refining energy was measured, whereupon a sample of 200 g (average) was taken.
  • the sample was analyzed to determine its freeness value (CSF), fibre distribution, fibre length and shives content.
  • CSF freeness value
  • a circulation water sheet was produced from the sample and analyzed to determine its density, tensile index, tear index, light scattering coefficient, light absorption coefficient and blue reflectance factor.
  • Tables 1 and 2 show the results of the analytical tests reflecting the refining result and the quality of the pulp.
  • test 3 In addition to the above-described test (test 3) illustrat strictlying the invention, two reference tests (tests 1 and 2) and two additional tests (tests 4 and 5) were carried out. The results of these tests are also presented in Table 1 below. The tests were performed as follows:
