Method for producing porous body |
摘要 |
An apparatus for producing a porous body that forms an expandable slurry containing at least inorganic powder, a foaming agent, and a binder into a sheet, causes the expandable slurry sheet to be foamed and baked, and thereby produces the porous body, the apparatus includes: a mixer preparing the expandable slurry by containing inorganic powder, a foaming agent, and a binder; a die-coater that has a discharge opening which discharges the expandable slurry provided from the mixer to an external thereof so as to shape the expandable slurry into a sheet; and a carrier sheet arranged so as to face the discharge opening of the die-coater with a gap interposed therebetween, and feeding the expandable slurry discharged from the discharge opening, wherein a flow path of the expandable slurry from inside the mixer to the discharge opening of the die-coater is hermetically sealed from an outside. |

1. A method for producing a porous body that forms an expandable slurry containing at least inorganic powder, a foaming agent, and a binder into a sheet, causing the expandable slurry sheet to be foamed and baked, and thereby producing the porous body, the method comprising the steps of:
deaerating a powdered slurry that contains the inorganic powder and the binder; preparing an expandable slurry by mixing the dearated powdered slurry and the forming agent; and incorporating gas bubbles into the deaerated powdered slurry, wherein the expandable slurry is hermetically sealed until the expandable slurry is formed into a sheet in order to prevent unexpected gasses from incorporating into the expandable slurry, thereby controlling a porosity of the porous body with a higher level of precision after preparing the expandable slurry from the inorganic powder, the foaming agent, and the binder.
