APPARATUS FOR PRODUCING POROUS BODY AND METHOD FOR PRODUCING POROUS BODY

摘要

Disclosed is an apparatus for producing a porous body, wherein an expandable slurry (S1) containing at least an inorganic powder, a foaming agent and a binder is formed into a sheet, and the thus-formed expandable slurry sheet (S2) is foamed and fired, thereby producing a porous body. This apparatus for producing a porous body comprises a mixer (15) for preparing the expandable slurry (S1) by containing the inorganic powder, the foaming agent and the binder, a die coater (5) for shaping which has a discharge opening (5b) for discharging the expandable slurry (S1) supplied from the mixer (15) to the outside, and a carrier sheet (7) arranged opposite to the discharge opening (5b) of the die coater (5) at a distance for conveying the expandable slurry (S1) discharged from the discharge opening (5b). The flow path of the expandable slurry (S1) from the inside of the mixer (15) to the discharge opening (5b) of the die coater (5) is hermetically sealed from the outside.
