VERFAHREN UND VORRICHTUNG ZUM HERSTELLEN VON CARBON-SCHAUM-PLATTEN
A method for producing carbon foam boards from starch for use as an insulation material or a filter is disclosed. The method is suitable for producing fine-pored carbon foam boards having a mainly homogeneous structure. This is achieved by sprinkling at least one very thin layer of foamable starch powder onto a temperature-resistant boardlike substrate, introducing the starch-powder-coated substrate into a furnace, introducing air, argon or nitrogen into the furnace until an internal pressure of ≈720 mbar to ≈1000 mbar has been established, heating the furnace to a foaming temperature of 180° C.-450° C. to foam the starch powder, maintaining the temperature over a prolonged duration of up to 10 hours to stabilize the foamed starch into a foam board.
