Interest in indoor air quality pollution has increased due to increased indoor life due to the spread of coronavirus. The World Health Organization recommends outdoor and indoor standards separately as a factor that adversely affects the extent that fine particle-sized dust among air pollutants causes human deaths. It is necessary to analyze fine dust generated indoors and take measures according to the amount of fine dust generated. Therefore, in this study, friction deterioration that can occur in indoor floor coverings was realized through a mechanical device and the difference in concentration and particle count was compared as deterioration occurred. In case 1, the maximum amount of 0.3~0.5㎛ particles during secondary deterioration was 28% different from that of 4.0~10㎛ particles.

Humidity and temperature are parameters that affect each other, and it is necessary to analyze the interrelationship of materials that affect each parameter. This study analyzed the influence of the material by producing an indoor finishing material. The effects of each other were compared by varying the mixing ratio of porous absorbent sediment (PAS) and micro-encapsulated phase change material (MPCM). It was confirmed that they affected each other"s ability, and hygroscopicity was not well controlled due to the increase in PAS. This requires an appropriate ratio of PAS and MPCM, and has been confirmed through heat and moisture experiments. It was confirmed that the ratio of PAS and gypsum was 0.35: 0.65, and the specimen containing 10% MPCM in the binder was the most appropriate ratio.
