METHOD OF MANUFACTURING ALUMINA-BASED HUMIDITY CONDITIONING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing an alumina-based humidity conditioning material which rapidly increases an adsorbing amount at a regulated optional humidity, can keep the humidity optionally at a certain level even at a place where a low humidity is locally required (a place such as a corner where dew condensation easily occurs) and can prevent dew condensation and propagations of molds and ticks. SOLUTION: The alumina-based humidity conditioning material is manufactured by heat-treating an aluminum hydroxide powder with an average particle diameter of≤50μm in the air. The heat-treatment is preferably given at a temperature of 300-800°C. COPYRIGHT: (C)2006,JPO&NCIPI
