Abstract: PURPOSE: A powdery self humidity control material is provided to control indoor humidity between 40 % to 70 % automatically irrespective of outdoor humidity changes. CONSTITUTION: The method comprises the steps of forming porous gel by reverse titration where sodium silicate solution is added to acid solution; aging the porous gel at pH 4.0 to 6.0, followed by washing, drying and calcination. Above reverse titration is not subject to redissolution process and carried out at 0 to 10 deg.C. The obtained powdery self humidity control material has porosity of 3.0 to 6.0 nm and porous volume of 0.7 to 1.0 cc/g.

Abstract: PURPOSE: A process of preparing artificial culture soil by mixing low quality ceramic material with additives such as paper making sludge, pulp waste water, etc. is provided which improves various physical properties such as air permeability, drainability, water retention properties and compression strength, etc., reduces manufacturing cost and recycles industrial wastes. CONSTITUTION: One or more components selected from kaolin, zeolite, coal ash and bentonite are mixed with paper making sludge and elvan at a speed of 300rpm, added with water, pulp waste water and sodium silicate, dried and then calcined at 900 to 1,100deg.C. Thus the obtained culture soil comprises 75 to 95% by weight of ceramic material containing the above one or more components, 2 to 15% by weight of paper making sludge and 3 to 7% by weight of elvan, and has a bulk density of 0.83 to 0.95g/ml, a compression strength of 26 to 64kg/cm¬2 and a void ratio of 50±5%.
