Method of manufaturing an active silica gel honeycomb adsorbing body usable in the atmosphere of 100% of relative humidity.

摘要

An active silica gel honeycomb adsorbing body usable for a process air having 100 % of relative humidity is manufactured. A single-faced corrugated sheet of wave length 2.5 - 4.5 mm and wave height 1.3 - 2.5 mm made of inorganic fiber papers of bulk density 0.3 - 0.6 g/cm<2> ( 30 - 180 g/m<2> ) and thickness 0.1 - 0.3 mm is laminated to form a honeycomb structure laminated body. The laminated body is impregnated with aqueous water glass solution, then impregnated with acid and dried to form active silica gel having micropores whose diameter is mainly distributed in the range of 20 - 40 ANGSTROM and whose surface area is 300 - 600 m<2>/gr, the active silica gel is adhered in fiber gaps and on the surface of inorganic fiber paper. <IMAGE>
