ABSTRACT:
A dehumidifier element is produced by alternately laminating corrugated paper and flat liner paper, both papers being of low density and composed of inorganic fiber such as ceramic fiber, to form a honeycomb matrix having many small channels penetrating through opposite surfaces. The formed matrix is fired with hot air to remove organic substances contained in the sheets, or the sheets may be fired before the lamination. The matrix is impregnated with water glass after the laminating process, or the sheets are impregnated before the laminating process. In either case, the formed matrix is soaked in an aqueous solution of aluminum sulphate or magnesium sulphate to form a silicate hydrogel on the papers and in the apertures between fibers of the papers. The shaped matrix and the metal silicate hydrogel are washed and dried to obtain a dehumidifying element having physical strength. The metal sulphate solution is cooled to precipitate and remove sodium sulphate from the solution. Additional sulphate is added to the metal sulphate solution for repeating the manufacturing process for another dehumidifier element. The main constituent of the element is metal silicate aerogel deposited in the apertures between the fibers of the inorganic fiber paper and on the inorganic fiber paper, which acts as an adsorbent.
