SILICA GEL, METHOD FOR PRODUCING THE SAME, PAPER CARRYING THE SAME AND SILICA GEL ELEMENT

摘要

PURPOSE: A manufacturing method of silica gel, silica gel deposited paper, and a silica gel element is provided to manufacture the silica gel products having high absorption efficiency. CONSTITUTION: Silica gel has a maximum value of pore distribution in a region of a pore diameter of 2.5nm or less. A ratio of sum pore volume of the sum of the pore volume and the sum of the pore diameter is 0.15~0.4. A manufacturing method of the silica gel includes the following steps of: gaining droplet materials by drying droplet consisting of a sodium silicate solution; gelling the gained droplet materials; and removing remaining sodium among a silica hydrogel.
