PCM PHASE CHANGE MATERIAL FOR ONDOL HEATING MANUFACTURING METHOD OF PARTICLES OF PHASE CHANGE MATERIAL FOR PREVENTING LEAKAGE PHASE CHANGE MATERIAL

摘要

The present invention relates to a phase change material (PCM) for ondol heating, and a manufacturing method of particles of the phase change material which prevents the phase change material from leaking out by successively coating the same in three steps using gypsum coating, polyvinyl alcohol (PVA) coating, and organic/inorganic nanocomposite resin coating, so as to utilize the phase change material to manufacture an ondol heating floor panel for dry construction.
