Application Number: JP,2024-175569
Category (FI): B29C44/36,B29C44/00@F,C01B32/205
Stage: PROBLEM TO BE SOLVED: To provide a method for producing fine-pored carbon foam boards having a mainly homogeneous structure regarding a method for producing carbon foam boards from starch for use as an insulation material or a filter.SOLUTION: The problem is solved by sprinkling at least one very thin layer of foamable starch powder 4' onto a temperature-resistant boardlike substrate 4, introducing the starch-powder-coated substrate into a furnace, introducing air, argon or nitrogen into the furnace until an internal pressure of about 720 mbar to about 1000 mbar has been established, heating the furnace 2 to a foaming temperature of 180degC to 450degC 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 11.SELECTED DRAWING: Figure 1 (Grant)
