Abstract

Fremgangsmåte for fremstilling av et polysakkaridskum, omfattende fremstilling av en vandig polysakkaridoppløsning, innføring av gass i denne slik at det dannes et vått skum, og tørking av dette med oppvarmet luft slik at det dannes et tørket polysakkaridskum. Det beskrives også fremstilling av et flerlags laminert polysakkaridskum gjen- nom lagvis anbringelse av minst to lag med tørket polysakkaridskum og trykk- belastning på lagene for å laminere disse til en kompositt-struktur. Et flerlags laminert polysakkaridskum fremstilles også ved lagvis anbringelse av minst to lag med kalsiumalginatskum, behandling av disse med en oppløsning av natriumklorid for omdannelse til et kal- sium-natrium-alginatskum, og vasking og tørking av det omdannede skum for å danne et flerlagslaminat.
