SHEET FOR TOTAL HEAT EXCHANGE ELEMENT, TOTAL HEAT EXCHANGE ELEMENT, TOTAL HEAT EXCHANGER, AND STEAM SEPARATION BODY

摘要

To provide a sheet for a total heat exchange element, a total heat exchange element, a total heat exchanger, and a steam separation body that achieve a high water vapor permeation speed and a high steam separation ratio.SOLUTION: A sheet for a total heat exchange element includes: a porous member including an organic fiber; and a membrane provided on one surface of the porous member and including an inorganic fiber with an average fiber diameter of 1-50 nm. When water is dropped on one surface of the porous member, an average extrapolation contact angle of three or more positions in an extrapolation contact angle at the time of dropping extrapolated from a temporal change in the contact angle is 100 or more degrees and less than 180 degrees, and an average contact angle of three or more positions after a lapse of five minutes from the dropping is 40 degrees or more and less than 180 degrees.SELECTED DRAWING: Figure 3
