Manufacture of air purifying agent

Abstract

Abstract PURPOSE:To manufacture an air purifying agent having excellent water resistance, strength, and air pollutant removing efficiency by adding water to potassium permanganate, zeolite, slaked lime, and colloidal silica, kneading, molding, and drying. CONSTITUTION:3-30pts.wt. potassium permanganate, 10-70pts.wt. zeolite, and 6-70pts.wt. slaked lime and colloidal silica are blended to obtain 100pts.wt. total solids. Then 10-100pts.wt. water is added to the 100pts.wt. total solids, and the mixture is kneaded, molded, and then dried at 50-150 deg.C. In that case, slaked lime and colloidal silica are blended in 0.5-10mol ratio of CaO/SiO2. The air purifying agent thus obtained exhibits a high absorbing and adsorbing performance of harmful gases such as NOx, SOx, and gaseous NH3, and does not disintegrate even in water. The agent, having water resistance and high particle strength, without generating dust, and easy to handle, can be utilized industrially.
