INORGANIC HYDROTHERMALLY SOLIDIFIED BODY, METHOD OF MANUFACTURING THE SAME AND MATERIAL USING HYDROTHERMALLY SOLIDIFIED BODY

摘要

PPROBLEM TO BE SOLVED: To provide a zeolite hydrothermally solidified body having high air permeability and water permeability and excellent function of deodorization and water cleaning. PSOLUTION: The zeolite solidified body is obtained by molding a kneaded material of zeolite powder, an active calcium source and water and subjecting the molded material to water hydrothermally solidification reaction in an autoclave. The quantity of raw material zeolite to be blended is several times to ten times of the quantity of the active calcium source and is set to have 0.1 mm average particle diameter. A part of the raw material zeolite and the active calcium source are reacted with each other to produce calcium silicate hydrate and the raw material zeolite and the active calcium source are solidified by the reaction to secure the strength and to form voids running in all direction. The function such as deodorization is kept because the quantity of zeolite is excessive compared to the quantity of the active calcium source and the high porosity is secured by the large particle diameter of the zeolite.
