Abstract
An object is to provide a dehumidifying member having a high tensile strength. The object can be achieved by a dehumidifying member including a honeycomb structure. The honeycomb structure includes a planar base material and a corrugated base material, a contact part where a wave top portion of the corrugated base material and the planar base material are in contact with each other, and an air hole. The contact part includes an adhesion part adhered by an adhesive agent and silica gel formed on the air hole side from the contact part. The component forming the adhesive agent differs from the component of the silica gel formed on the air hole side from the adhesion part.
Claims16
A dehumidifying member comprising a honeycomb structure,
- wherein the honeycomb structure includes
- a planar base material and a corrugated base material, and
- a contact part where a wave top portion of the corrugated base material and the planar base material are in contact with each other, and
- an air hole,
- wherein the contact part includes
- an adhesion part adhered with an adhesive agent, and
- synthesized silica gel, which is a silica gel synthesized from sodium silicate, formed on the air hole side from the adhesion part, and
- wherein a component forming the adhesive agent differs from a component of the synthesized silica gel formed on the air hole side from the adhesion part,
- wherein the planar base material and/or the corrugated base material is mixed paper,
- wherein the mixed paper is a sheet-like base material made with hygroscopic particles filled in space between fibers of a fibrous base material forming the planar base material and/or the corrugated base material.
A manufacturing method dehumidifying member, the manufacturing method comprising:
- a carrying step of causing a honeycomb structure to carry a sodium silicate solution;
- and
- a silica gel synthesis step of synthesizing silica gel to form synthesized silica gel by performing acid treatment on sodium silicate carried in the honeycomb structure by the carrying step,
- wherein the honeycomb structure includes
- a planar base material and a corrugated base material,
- an adhesion part adhered with an adhesive agent that adheres a wave top portion of the corrugated base material and the planar base material to each other, and
- an air hole,
- wherein the synthesized silica gel of the silica gel synthesis step forms, together with the adhesion part, a contact part where a wave top portion of the corrugated base material and the planar base material are in contact with each other,
- wherein a component forming the adhesive agent differs from a component of the synthesized silica gel formed on the air hole side from the adhesion part,
- wherein the planar base material and/or the corrugated base material is mixed paper,
- wherein the mixed paper is a sheet-like base material made with hygroscopic particles filled in space between fibers of the fibrous base material forming the planar base material and/or the corrugated base material.
