SINTERED BODY OF POROUS BALL TYPE HAVING MULTI-FUNCTUIN OF DEODORINGATION, DEHUMIDIFI-CATION AND ANTIBIOSIS ETC

摘要

PURPOSE: A multifunctional porous spherical sintered body is provided to have excellent deodorization, dehumidifying, antibiotic, far-infrared radiation, and anion generating functions by using a natural volcanic ash powder, an inorganic antibacterial agent, and a charcoal powder. CONSTITUTION: A manufacturing method of a multifunctional porous spherical sintered body comprises the following steps. A spherical composition comprised of 94 to 98.5 parts by weight of a natural volcanic ash powder of 80 to 200 mesh, 0.5 to 1.0 part by weight of an inorganic antibacterial agent, 1.0 to 5.0 parts by weight of a charcoal powder is prepared. A plasticization material is obtained by adding 110 parts by weight of plasticization water based on 100.0 parts by weight of the spherical-shaped composition. A spherical structure is molded by using the plasticization material to a size of 2 to 20 mm. The spherical structure is dried at a temperature of 100 to 200°C in a drying furnace for about 2 to 24 hours to obtain a spherical structure having a moisture content of 10% or less. The dried spherical structure is sintered at a temperature increasing at a constant rate from 300°C to 1000°C for 3 to 5 hours. The inorganic antibacterial agent is prepared by substituting an antibiotic metal ion to zirconium phosphate or a zeolite carrier.
