Claims (12)

1. Postupak prikupljanja drvnih vlakana iz obrađenog drvnog materijala, naznačen time što obuhvaća slijedeće korake: miješanje isječenog obrađenog drvnog materijala s vodom kako bi se dobio mulj; i propuštanje električne struje kroz mulj kako bi se zagrijao isječeni drvni materijal, a time i oslabilo veze između drvnih vlakana u drvnom materijalu.1. The process of collecting wood fibers from processed wood material, characterized by the fact that it includes the following steps: mixing the chopped processed wood material with water to produce a slurry; and passing an electric current through the sludge to heat the cut wood material and thereby weaken the bonds between the wood fibers in the wood material. 2. Postupak u skladu s patentnim zahtjevom 1, naznačen time što se mulj grije do temperature između 30 °C i 99 °C.2. The process according to claim 1, characterized in that the sludge is heated to a temperature between 30 °C and 99 °C. 3.

A process according to any preceding claim, characterized in that the step of mixing the sludge further comprises the addition of an electrolyte. 8. Postupak u skladu s bilo kojim prethodnim patentnim zahtjevom, naznačen time što korak miješanja mulja dodatno obuhvaća dodavanje površinski aktivnog sredstva.8. A method according to any preceding claim, characterized in that the step of mixing the sludge additionally comprises the addition of a surfactant. 9. Postupak u skladu s bilo kojim prethodnim patentnim zahtjevom, naznačen time što je prosječna veličina komada isječenog obrađenog drvnog materijala u rasponu od 25 mm do 45 mm.9. A method according to any preceding claim, characterized in that the average size of the pieces of cut treated wood material is in the range of 25 mm to 45 mm. 10. Postupak u skladu s bilo kojim prethodnim patentnim zahtjevom, naznačen time što dodatno obuhvaća korak izdvajanja nečistoća iz mulja prije ili nakon koraka grijanja.10. A process according to any preceding patent claim, characterized in that it additionally comprises the step of extracting impurities from the sludge before or after the heating step. 11. Postupak u skladu s bilo kojim prethodnim patentnim zahtjevom, naznačen time što se, nakon grijanja, mulj podvrgava brzom vakuumiranju.11. A process according to any preceding patent claim, characterized in that, after heating, the sludge is subjected to rapid vacuuming. 12. Postupak u skladu s bilo kojim prethodnim patentnim zahtjevom, naznačen time što dodatno obuhvaća prebacivanje mulja kroz posude u kojoj se provodi korak grijanja u kontinuiranom postupku.12. A process in accordance with any previous patent claim, characterized in that it additionally comprises the transfer of sludge through vessels in which the heating step is carried out in a continuous process.
