Title:
MESOPOROUS HUMIDITY-CONTROL MATERIAL, METHOD FOR PRODUCING MESOPOROUS HUMIDITY-CONTROL MATERIAL, AND HUMIDITY-CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/054399
Kind Code:
A1
Abstract:
Provided is a mesoporous humidity-control material containing a compound represented by formula (X), wherein α defined in formula (1) is 0.18 or less. Formula (X): SiO2⋅nMOm/2 (In formula (X), M represents a polyvalent metal atom, m represents the valence of the polyvalent metal atom, and n represents a number from 0.001 to 0.1 inclusive.) Formula (1): α = 1 - B1/A1 (In formula (1), A1 represents the BET specific surface area of a mesoporous tempered material, and B1 represents the BET specific surface area of the mesoporous tempered material treated under the following treatment conditions. (10) 0.1 g of a mesoporous humidity-control material is added to a beaker. (11) 10 cc of water are added into an autoclave having an internal volume of 50 cc. (12) The beaker is accommodated so that part of the beaker is submerged in the water in the autoclave, and the autoclave is sealed. (13) The autoclave is kept in a 100°C electric furnace for 24 hours. (14) The autoclave is unsealed and the mesoporous humidity-control material is taken out.)
