Element for humidity exchanger, humidity exchanger medium and method of manufacturing same

摘要

The humidity exchanger medium is manufactured by forming a laminate of (i) a corrugated sheet and (ii) a flat sheet bonded to points of contact of a ridged surface of the corrugated sheet, the laminate having been impregnated with sodium silicate waterglass and then partially dried, each corrugated and flat sheet constituted of a paper of inorganic fibers; forming a honeycomb matrix from at least one laminate; soaking the honeycomb matrix in an acidic solution containing at least a titanium inorganic salt to convert the sodium silicate waterglass to a titanium-containing silicate hydrogel; and washing and drying the honeycomb matrix to convert the titanium-containing silicate hydrogel to a titanium-containing silicate aerogel.
