Claims (18)

  1. Ett förfarande för att framställa ett fast skum innefattande 75-95 viktsprocent cellulosafiber, beräknat på skummets totala vikt, varvid metoden innefattar deponering av diskreta enheter av skum på en yta för att erhålla en första skumdeponering, deponering av ett vått skum mellan de diskreta enheterna för att erhålla en ytterligare skumdeponering, och torkning av det våta skummet för att erhålla ett fast skum i vilket diskreta enheter av skum är inneslutna i en skummatris, och varvid densiteten på skummet i de diskreta enhterna är högre än densisteten på skummatrisen.
  2. Förfarandet enligt patentkrav 1, varvid höjden på de diskreta enheterna är fråntill 100% av höjden på det våta skummet i den ytterligare skumdeponeringen.
  3. Förfarandet enligt något av patentkraven 1 eller 2, varvid det våta skummet i den ytterligare skumdeponeringen innefattar åtminstone 10 viktsprocent cellulosa, beräknat på det våta skummets totala vikt.
  4. Förfarandet enligt något av patentkraven 1-3, varvid de diskreta enheterna erhålls genom distribuering av ett vått skum i diskreta enheter på en yta, företrädesvis i cylinderform, följt av torkning av det våta skummet.
  5. Förfarandet enligt något av patentkraven 1-3, varvid de diskreta enheterna erhålls genom extrudering av ett vått skum, torkning av skummet, skärning av det torkade skummet till diskreta enheter, och deponering av de diskreta enheterna på en yta.
  6. Förfarandet enligt något av patentkraven 4-5, varvid det våta skummet som används i de diskreta enheterna innefattar åtminstone 10 viktsprocent cellulosa, beräknat på det våta skummets totala vikt.
  7. Förfarandet enligt något av patentkraven 1-6, varvid det våta skummet har en densitet från 70 - 600 kg/m
  8. Förfarandet enligt något av patentkraven 1-7, varvid det fasta skummet har en densitet på 10 - 80 kg/m
  9. Förfarandet enligt något av patentkraven 1-8, varvid densiteten på skummet i de diskreta enheterna är åtminstone 110% av densiteten på skummatrisen.
  10. Förfarandet enligt något av patentkraven 1-9, varvid bredden på varje diskret enhet år mindre än 1,3 gånger dess höjd.
  11. Ett fast skum kånnetecknat av att det innefattar diskreta enheter av skum inneslutna i en skummatris, varvid densiteten på skummet i de diskreta enheterna år högre än densiteten på skummatrisen, och varvid det fasta skummet innefattar åtminstone 75-95 viktsprocent cellulosafiber, beräknat på skummets totala vikt.
  12. Ett fast skum enligt patentkrav 11, varvid höjden på de diskreta enheterna år från 90 till 100% av höjden på skummatrisen.
  13. Ett fast skum enligt något av patentkraven 11 eller 12, varvid det fasta skummet har en densitet på 10 - 80 kg/m
  14. Ett fast skum enligt något av patentkraven 11-13, varvid varje diskret enhet av skum omges av ett tätare skumskikt.
  15. Ett fast skum enligt något av patentkaven 11-14, varvid varje diskret enhet har en cylinderform.
  16. 16. Ett fast skum enligt något av patentkraven 11-15, varvid densiteten på skummet i de diskreta enheterna är åtminstone 110% av densiteten på skummatrisen.
  17. 17. Ett fast skum enligt något av patentkraven 11-16, varvid bredden på de diskreta enheterna är mindre än 1,3 gånger dess höjd.
